Common Wiring Diagrams

Common

terminals

Wyze Wire

terminals

Meaning

This wire controls the blower fan, which is

responsible for pushing warm or

cool air through all the vents in your house.

This stands for the “common” wire in an HVAC

system, and it provides power to

the thermostat.

Y, Y1

The Y wire is used to send a signal to your

HVAC system telling it to fire up the

air conditioner. For cooling.

Second stage cooling.

W, W1

Just like the Y wire, the W wire(s) control the

heating aspect of your system.

This works nearly identically to auxiliary heat,

but for emergency purposes only.

It has to be turned on manually, whereas

auxiliary heat can turn on automatically if need

be.

O, O/B

O/B

These wires are responsible for switching the

changeover valve in a heat pump system.

The O wire reverses the valve from heating to

cooling, and the B wire switches the

valve from cooling to heating.

W2, Aux

Second stage heating, usually auxiliary

(electric) heating.

Less common thermostat wires:

Uncommon

terminals

Wyze Wire

terminals

Meaning

X, X1, X2

W1, W2 or

X wire is for back-up on a heat pump

and allows for auxiliary heating from

the back-up heat source.

C or O/B

Some systems use B for common

wire. Determine if your B wire is a

common or O/B wire.

ACC, H, Hum,

Hum1,

H2, Hum2, D, DH,

Dhum, Dehum,

D2,

Some thermostats have this terminal

to connect equipment like

a whole-house humidifier or

dehumidifier.

Not needed

The L wire is a system monitor and

used to light a light on the thermostat.

S, S1, S2, T

Not needed

These wires run directly outside and

provide outdoor temperature

information to the thermostat.

Complete Installation Instructions

The Wyze app provides a thorough installation guide. However, here

are some more detailed instructions to walk you through the process

of installing your Wyze Thermostat.

Begin installation with the app

1. You must have the latest version of the Wyze app to complete

setup. Download it from the Apple App Store or from Google

Play. If you don’t already have a Wyze account, the app will

ask you to create one and sign in.

2. Tap the plus sign (+) on the upper left corner of the screen on

the app’s home screen.

3. Select Add Device, then Home and Wyze Thermostat to

start the setup guide.

4. The app will show you how to install your thermostat. It will

also ask you some questions about your current thermostat’s

wiring. Answer these questions as accurately as possible.

You’ll get a custom wiring diagram for your system after you’ve

selected your wires.

Step 1. Turn power off

To protect yourself, turn off the switch that controls your

heating/cooling system at the breaker box or use the switch on your

furnace or air handler. If necessary, turn off the main power at the

breaker box. After verifying the power is off, confirm in your app by

tapping Next.

Breaker box switch

Power switch at the furnace

Note: Try changing the temperature on your old thermostat. Wait 5

minutes to make sure that the system does not run.

Step 2. Remove your existing thermostat cover

On most thermostats, you can take off the thermostat cover by

grasping and gently pulling it off. Some thermostats may have screws,

buttons, or clasps to undo. Use the included screwdriver to remove all

the screws or use the button/clasps to remove the cover. You should

have wires that run from your heating/cooling system attached to the

back panel of your old thermostat, and your thermostat’s back panel is

screwed to the wall. Tap Next to confirm.

Note: Do not remove any wires at this step! If you don't see any wires,

you may have a mid-layer that needs to be removed by unscrewing.

Step 3. Make sure you are not using a high voltage system

If your existing thermostat has:

1. 110/120V thick wires capped with wire nuts,

2. Caution label saying 120/240V,

3. Only two terminals labeled as L1 and L2,

Then it is a high voltage system and is not compatible with Wyze

Thermostat. You can find information about our Wyze return policy at

https://wyze.com/return-warranty-policy. If you do not have a high

voltage system, confirm in the app by tapping No to continue.

Step 4. Take picture of your current thermostat wiring

Don't forget to include the letters next to the terminals where the wires

are inserted. This will be a helpful reference when wiring your

thermostat. We’d greatly appreciate it if you shared your old wiring

pictures with us so we can improve our training materials.

Step 5. Remove jumper wires

Your old thermostat may have a jumper wire connecting one terminal

to another. It may look like a small staple or a colored wire. Use a

screwdriver or press a lever to release the wires from their terminals

and remove the jumper wire. Your Wyze Thermostat does not require

any jumper wires.

Note: Do not disconnect any other wires in this step.

Step 6. Get a wiring diagram from the Wyze app

To get a custom wiring diagram for installation, simply follow the Wyze

app’s thermostat installation instructions. Select the letter(s) of all the

terminals with wires connected on your old thermostat. The Wyze app

is confirming the thermostat’s compatibility before moving to the next

steps.

The Wyze app will generate a customized wire diagram with how your

wiring should look like to make your installation easier.

Note: If you don't have a C-wire selected in the compatibility checker,

you will need to install a C-wire adapter to supply power to your Wyze

Thermostat.

Some common issues:

1. Thermostat with 2 sets of labels: Some thermostats may have

2 sets of terminal labels, including "conventional" and "heat

pump". Please select the terminal names based on your actual

system.

2. Unused wire(s): It is best to identify if the wire is used at the

control panel as well. If the wire is being used at the control

panel, please label it clearly with the included label. If it is not

being used, label your unused wire with the empty sticker

label.

3. Two wires in one terminal: You may have a dual transformer

system.

Incompatible wires:

1. Stranded wires: Wyze Thermostat is not compatible with

stranded wires. Do not connect Wyze Thermostat to stranded

wires.

2. High voltage wires: If your thermostat is labeled 120V or 240V

or has thick wires with wire nuts, your system is high voltage

and isn’t compatible with Wyze Thermostat. Do not connect

Wyze Thermostat to high-voltage wires.

Step 7. Label the wires

It is time to install your Wyze Thermostat! Using the old thermostat

base as a guide, put the provided sticky label on each wire as you

disconnect it. Make sure all wires are disconnected from the old

thermostat.

Note: Label wires according to old thermostat terminal designations,

NOT by wire color.

Step 8. Disconnect and remove your old thermostat

Remove the old thermostat’s back panel by unscrewing it from the

wall after wires are all labeled and disconnected. Make sure the wires

do not fall back into the wall due to gravity.

Step 9. Mount your Wyze Thermostat back panel

Thread the wires through the center of the back panel (the wall cover

is optional). Hold the back panel to your wall, use a pencil to mark the

holes for your thermostat to be placed. Drill mounting holes for the

drywall anchors (e.g., 3/16 inch holes for drywall).

Use the included drywall anchors and screws to mount the back panel

to the wall. Keep centering the bubble on the built-in level to make

sure your thermostat is in alignment.

Note：You may use your existing wall anchors. Hold the back panel up

against the existing anchors to check for alignment.

Step 10. Connect the wires to Wyze Thermostat

Push down on the levers to insert the wires into the inner holes of

their corresponding terminals on the wall panel (only one wire per

terminal) until it is firmly in place. Gently tug on each wire to verify

they are securely connected. If you need to release the wires again,

push down on the terminal levers.

Note: Make sure the wires have at least 1/4'' exposed for inserting to

the back panel terminals

Step 11. Attach Wyze Thermostat to the back panel

Push excess wires back into the wall and snap your Wyze Thermostat

into the back panel. After a satisfying "click" sound, your Wyze

Thermostat is ready for setup.

Step 12. Turn on on the power

Go back to the circuit breaker or where you powered off your system

to turn on the power. Wait a moment for the Wyze logo to appear on

your screen. It is now in pairing mode. Follow the app instructions to

personalize your thermostat settings and enjoy！

Installing a thermostat with less common

configurations

3-wire heating-only thermostat system (R, G, W)

For a heat-only system that only contains connections R, G, and W,

The G wire can be repurposed as a C-wire.

1. Identify the G wire at your control board.

2. Remove the G wire from the G terminal on the control board

and connect it to the C terminal at the control board.

3. Connect a jumper wire from the W terminal to the G terminal

on the control board.

4. At the thermostat, label the G wire from the old thermostat as

the C-wire.

5. Follow the Wyze app to complete installation, selecting the Rc,

C, W wires.

NOTE: To keep fan power, you’ll need to add an additional jumper

wire between the G terminal and the W terminal. You will lose

independent fan control.

Installing your Wyze Thermostat with a boiler and AC (dual

transformer system)

If you have a boiler as well as an air conditioner, you have a dual

transformer system. The installation process for a dual transformer

system is different from a standard installation, so please refer to the

information below.

With dual transformer setups, you will have two R wires—one from

the cooling transformer (RC) and one from the heating transformer

(RH).

It’s also important to note that your C-wire must come from the

cooling side. If your current thermostat has a C-wire that’s coming

from your boiler, this will not work with Wyze Thermostat. If you

don’t already have a C-wire coming from your air handler, you have

two options:

1. Run an additional wire from the air handler to Wyze

Thermostat to use as a C, or

2. Repurpose your G wire as the C using the CWA.

Setting up your Wyze Thermostat

After installing the thermostat and powering it, your Wyze Thermostat

will guide you through a series of simple questions about setting your

temperature preferences, and about your heating and cooling system.

This information is used to set your comfort preferences and save on

energy.

Configuring your Wyze Thermostat for the first time

Turn the knob on the thermostat like a dial to highlight different

options and press it like a button to make your choices. Below are the

topics your thermostat will cover during setup. Select each to learn

more.

Equipment detected

Your thermostat will show you the wires it detects in its connectors.

● If there’s a wire missing, pull off the thermostat display and

check that each wire is fully inserted into their connector, and

that the connector button stays down.

● If you see a wiring error on your thermostat you’ll need to fix it

before continuing. If you selected less wires in the wire

selections stage in the app than you connected in the

thermostat terminals, ensure that the wires connected are

correct and restart the installation process in the app to select

the correct wires.

Once you’ve confirmed the wiring is correct, your thermostat will ask

some questions about your system, such as what kind of fuel it uses

and what type of heating you have.

Fuel Source

If you have a conventional system installed, your thermostat will ask

about the fuel source for your heat and how that heat is delivered.

Wyze Thermostat uses this information to determine how to control

your heating and cooling system.

If you know your fuel source, select it from the list. You can also

choose “I don’t know/Others” if you’re not sure.

Type of heating

You may also be asked whether you have a furnace/forced air, in-floor

radiant, or a radiator system for heating. For help determining what

kind of heating you have, go to the following article.

How can you tell which heating system you have?

Forced

Air

With this kind of heating system, warm air comes out of

vents throughout your home.

In-Floor

Radiant

This utilizes electric coils or hot water pipes under the

floor of your home to provide heating.

Radiators

Radiators are sealed metal containers filled with hot

water, steam or electric coils. They’re similar to in-floor

systems, since they don’t use vents or fans, but

radiators aren’t installed under the floor.

Finish setup with the app

Once your thermostat is connected to your account, the Wyze app will

ask you a few more questions about setting a temperature schedule

and testing your system.

Basic Functions

Adjusting the temperature preferences

● To access your preferences, tap Menu > Settings >

Thermostat Preferences. Refer to the User Guide

(Configuring Personal Preferences).

1. Tap on the State (Home, Away and Sleep) to edit that specific

temperature.

2. Tap on the temperature to change it.

3. Tap Save to go back to the temperature preference page and

tap on Save again to confirm the changes.

Adjusting heat/cold comfort settings

Auto mode on your Wyze Thermostat will display two set points—one

for heating and one for cooling. The cooling set point is blue while the

heating set point is red.

To enable this system mode, tap on Controls on the Main Menu to

display the control options and then select Auto under modes to

activate it.

Setting Schedule on Your Wyze Thermostat

Go to the schedule tab from the main settings menu: Settings >

Schedule. You will see your schedule for the day. Tap on any of the

already existing schedules to view or edit your schedule for that

specific day. If you wish to add a new schedule into your schedule list,

tap the + icon in the bottom left corner.

You will have the option to choose the State for the schedule (Home,

Away and Sleep). Select the State you wish to add and then set the

time for the schedule.

After setting the time, tap Heat to and Cool to to set the heating and

cooling temperatures, respectively.

Tap Save in the bottom right corner to save your new schedule.

Adjusting the fans of your HVAC system

The fan control under advanced settings allows you to either control

the HVAC fan using the thermostat control logic or use the control

logic of the HVAC. It also allows you to either run the fan in Auto Mode

or On Mode

Wyze Thermostat has 3 fan control modes as shown below:

● Auto: The fan will only run with the cooling stage. (It is always

necessary for any system to run the fan with the cooling

system).

● Cycle: Configurable in Settings > Advanced > Fan Cycle.

Cycle is configurable from 0 min/hr to 55min/hr. Note: This is

the minimum amount of time the fan will run each hour. This

means the time the system is in the cooling stage and running

the fan is counted towards the fan cycle time.

● On: The fan will run continuously.

Fan Control

Under the fan control, you can choose On (the fan runs continuously)

or Auto in which case the fan will run according to the fan cycle time

selected in Settings > Advanced > Fan Cycle. The default 0 min/hr

fan cycle time means that the fan will turn off immediately after the

heat is turned off. Any of the other fan cycle times mean that the fan

will run for that duration within every hour.

Fan Activation Delay:

This setting allows you to determine when your furnace blower fan

should turn on during heating. Users can either select By Furnace,

15s, 30s, 45s or 60s. If you select By Furnace, the furnace fan will

be controlled according to the furnace control logic during heating.

However, if you select any of the times listed, the thermostat will turn

on the furnace fan at the set time during heating. This means that if

you select 15s, the fan will turn on after 15 seconds of heating.

To set this, go to Settings > Advanced > select fan activation delay

and choose your desired setting.

Note: The default setting for fan activation delay is By Furnace. For

conventional units, Wyze Thermostat is automatically configured to

have a 15 second Fan delay. This means that, when the furnace is

turned on, the fan does not turn on immediately. The fan only turns on

30 seconds later to allow enough time for the furnace to heat up.

Customizing Your Thermostat

Renaming your Wyze Thermostat

Go to Settings > Name. You can choose from a list of suggested

names, or enter the name you wish to use for the device in the text

box. If you have multiple devices, this will help differentiate where in

the home the thermostat is located and will be used for device

organization and voice commands.

Smart Home/Away

Auto Switch is a feature that can be turned on to use geofencing when

the Away routine starts, and return to your scheduled temperatures

when the Home routine starts.

To access this feature:

1. In your phone settings, allow the Wyze app to access your

location.

2. In the Wyze app, add a home address for the app to know if

you are home or away by tapping Wyze Thermostat >

clockwise to the Settings icon.

2. Press the knob again to enter your settings.

3. Turn the knob clockwise again to the Lock icon.

4. Press the knob to lock or unlock the thermostat.

Setting Weekly Schedules

Time-Based scheduling: Program your thermostat for one week; each

day (each day is a different schedule); or any group of days, like

Mon-Fri, Sat, Sun, or Mon-Fri, Sat-Sun. You can further customize the

temperature of a specific time period without changing the rest of the

time slots.

Deleting Schedule

To delete a schedule from your list of schedules, swipe left on that

schedule. A Delete icon will appear. Tap the icon to delete the

schedule.

Auto Switch

When the Auto Switch feature is enabled, we’ll use the motion sensor

in the thermostat and the location of your phone to switch between

Home and Away status. Your thermostat will switch from Home to

Away when your phone is 3 km away from home, or switch from Away

to Home when your phone is within 3 km from home. Once the motion

sensor detects movement in front of the thermostat while the status is

Away, it will switch to Home.

The Auto Switch feature can be toggled on/off in your settings.

Coast to Cool

Wyze Thermostat can send a signal to turn off your compressor or

furnace before the end of a cooling cycle or heating cycle, and keep

the fan on to blow the remaining cool air or warm air into your home.

This feature can help save energy during summer or winter months.

Humidity Preferences

If the * terminal has been connected with an integrated (whole house)

humidifier or dehumidifier, the thermostat can turn the accessory

device on to moderate the humidity level. Go to Settings > Humidity

Preferences to adjust the desired humidity level.

Safety Temps

Safety Temps can help protect your home from extremely cold or hot

weather by turning on your heating or cooling system when your set

limits are reached, even if your thermostat is set to Off or no heating is

scheduled. You will receive a notification when the safety temperature

is reached.

By default, your heating Safety Temp is set to 40°F / 4°C and cooling

is off. But both can be adjusted by going to Settings > Advanced >

Safety Temperature.

For example, when the weather becomes lower than the frost point

when you are away from home, Wyze Thermostat can heat the room

up to prevent low temperatures from damaging your water pipes.

Another good use of this feature is when you have to leave plants or

pets at home. You can set the Safety Temp higher in the winter and

lower in the summer to keep them comfortable during extreme

temperatures.

Note: This feature works without WiFi.

Differential Temp

You can set the value of the minimum difference between the current

temperature and set temperature before the system calls to heat or

cool. A smaller difference means shorter cycle times, whereas a larger

difference results in longer cycle times. By default the differential temp

is 1°F which means if the heat is set to 65°F the thermostat will turn

the HVAC on when the temperature falls to 65°F. A higher differential

temp will help prevent unnecessary short cycles from wearing out

your heating/cooling system and reduce starting cost. The

temperature range is adjustable from 0.5ºF to 3°F (0.5ºC to 2°C) by

going to Settings > System > Differential Temp.

Minimum Comfort Zone

Minimum Comfort Zone is the minimum difference between the heat

mode set temperature and the cool mode set temperature when the

system mode is in Auto Mode. The delta is adjustable from 3ºF to

10°F (1.7ºC to 5.5°C). The default value is 5°F (2.8°C).

Temperature & Humidity Correction

Wyze Thermostat has built-in temperature and humidity sensors that

are calibrated during production. If the sensors seem to be

consistently reading slightly above or below the actual temperature or

humidity, you can adjust it with a reference thermometer. For example,

if the thermostat reading is higher than your reference temperature,

apply "-1". or "-2" in this setting.

You can update these features in Settings > Advanced >

Temperature Correction or Settings > Advanced > Humidity

Correction.

Minimum Runtime (Short Cycling

Protection-alternative name) (N/A)

If the compressor is restarted too soon after a shutdown, system

damage can occur. This feature allows the compressor to wait a few

minutes before restarting, helping to prevent damage to the heating or

cooling system. During the brief wait period, the thermostat will show

Cool on (or Heat on if you have a heat pump) until the wait period is

over, at which point the compressor will turn back on. The time is 5

minutes by default, but you can adjust it from 2 to 8 minutes by going

to Settings > System > Minimum Runtime.

Changing Measurement Units

You can switch between using Celcius and Fahrenheit by going to

Settings > Advanced > Temperature Units.

Note: this setting will be applied on both Wyze Thermostat and the

Wyze app when adjusting and displaying the temperature. The unit for

system settings will always be in Fahrenheit.

HVAC Accessories (* Terminal)

Wyze Thermostat offers an accessory terminal that is capable of

connecting to 1 of the following 4 devices:

1. Dehumidifier. To configure the dehumidifier, select:

1. Cooling: Dehumidifier will only run when cooling stage

is active and the humidity is outside the desired range.

2. Fan: Run the fan when the dehumidifier is active.

3. Energize: Active on or Active off.

2. Humidifier. To configure the humidifier, select:

1. Fan: Runs the fan when the humidifier is active.

2. Heating: Humidifier only runs when the cooling stage is

active and the humidity is outside the desired range..

3. Ventilator.

4. Emergency Heat. Can be activated from the settings in the

Wyze app. Note: This feature is only available when

Emergency Heat is chosen as the * terminal during the setup

process. Emergency Heat can only be turned on manually by

going to Settings > Advanced in the Wyze app.

Sharing Access

You can share access to the thermostat with your family members,

roommates, and even Airbnb guests.

Restrictions on shared devices:

There are some restrictions to what a shared user can do in the Wyze

app. A shared user:

1. Cannot name or rename the device.

2. Cannot share the device with others.

3. Cannot execute OTA.

4. Tapping on the Delete Device icon in Settings only removes

the device from the shared user's Wyze app device list, but

does not delete the device from the primary user's list.

Important:

Shared devices can use Auto Switch. This means anyone who leaves

home who activates Auto Switch, changes the state to Away.

Hold Schedule (Going on Vacation)

Use this feature when you go on vacation or are away from home for

an extended period of time. Quickly access the Hold function on the

controls panel on Wyze Thermostat’s page in the app. When enabled,

motion detection and the Auto Switch features will be disabled but you

will still receive notifications. Three configurations are available:

● Indefinitely: Schedule is on hold until you manually turn it off.

● Time: Set the time for your schedule to resume.

● Date: Set the day for your schedule to resume.

Filter reminder

Wyze Thermostat has a built-in filter management system that can

store filter information like sizing factors. You will be notified when the

filter needs to be replaced.

Installing Zone Control

Wyze Thermostat is compatible with most zone control systems,

including zone systems with dampers. However Wyze Thermostat

uses standard thermostat connections; proprietary connections such

as DAMP or MISC are not compatible.

Zoned Systems: If your house has multiple thermostats connected,

then it can be considered a zoned system. A zoned system will use

dampers in the HVAC duct to open and close off zones in your house.

You can replace one or all of your thermostats with a Wyze

Thermostat.

Master/Slave

In a master/slave controlled HVAC system, one thermostat (master)

controls the other thermostats (slave). Some master slave

configuration thermostats may not be compatible.

Thermostat controlled dampers

Some dampers are controlled from the thermostat through specialty

wiring connections on the thermostat, such as Damp. Wyze

Thermostat is not compatible in this case.

Zoned system panels

By far the most common type of zone system utilizes a zone system

panel. Wyze Thermostat is compatible with most of these panels. If

the old thermostat doesn’t have special terminals like MISC or Damp

then it will be compatible. Follow the Wyze app to install as normal.

Zoned system panel without C-wire

Connecting the C-Wire Adapter (CWA) module to a zoned system is

almost the same as connecting to a normal control board. Two things

to remember:

1. Identify the correct control board. Your system may have

multiple control boards. You must identify the zone control

board, as that will be the board used to connect the C-wire

adapter.

2. Identify the correct zone on the panel. As shown below, the

panel can connect several thermostats. You must identify

which zone thermostat you are changing.

3. Connect the C-Wire Adapter (CWA). Follow the Wyze app

for how to connect the thermostat. Remember, connect the

CWA to the zone thermostat wires. Refer to the image below

for a common wiring scenario.

Troubleshooting

Common Stages

Determine if your B wire is a common or O/B wire

Most thermostat manufacturers use C to designate the connector for

the common wire. However there are some Trane, American

Standard, and York thermostats that use B for the common wire. To

address this, check:

1. If you’re installing a Wyze Thermostat to control a heat pump

system and the current thermostat has both a B and a C,

connect the B to the Wyze O/B terminal and connect the C to

the Wyze C terminal.

2. If you’re installing a Wyze Thermostat to control a heat pump

system and the current thermostat has both an O and a B,

connect the O to the Wyze O/B terminal and connect the B to

Wyze C terminal.

3. If you’re installing a Wyze Thermostat to control a heat pump

system and the current thermostat only has a B wire, connect

the B to the Wyze O/B terminal and install a CWA.

4. If you’re installing a Wyze Thermostat to control a conventional

system (non heat pump) and you see a B wire connected to

the current thermostat, that B is a common wire and should be

connected to the C terminal on Wyze Thermostat.

Important: If you have a B wire that is actually a common wire, not

following the rules above can lead to blowing a fuse on your HVAC

controller board and, most likely, damaging your WyzeThermostat.

When X, W1 or W2 is an AUX wire

In a heat pump system, W1, W2, X, X1 or X2 are used to turn on

auxiliary heat and one of them should be attached to the W1 or W2

terminal in your Wyze Thermostat. You should, however, verify that

the X wire on the old thermostat is not a common wire. Once you’re

sure, you can assume that the X is the auxiliary heat and should be

inserted into the W1 or W2 terminal on Wyze Thermostat depending

on the available terminal after connecting the other wires.

1. If you’re installing a Wyze Thermostat to control a heat pump

system and the current thermostat has both an X and a C,

connect the X to the Wyze W1 or W2 terminal and connect the

C to the Wyze C terminal.

2. If you’re installing a Wyze Thermostat to control a heat pump

system and the current thermostat has an X and both O and

B (where B is C), connect the X to the Wyze W1 or W2

terminal and connect the B to the Wyze C terminal.

3. If you’re installing a Wyze Thermostat to control a heat pump

system and you see an X wire connected to the current

thermostat without a C-wire, that X is a common wire and

should be connected to the C terminal on Wyze Thermostat.

Changing from an ecobee PEK

If you have an ecobee PEK, follow this guide to change the PEK to

the Wyze CWA.

Note: The ecobee PEK and Wyze CWA are not the same, and Wyze

Thermostat is not compatible with the PEK without some

configuration.

Control Board:

At the control board, we will need to switch out the PEK for the CWA.

Wyze Thermostat CWA and ecobee PEK wiring line up directly the

same at the control board. So it is very simple to change the wiring

from the PEK to the CWA.

1. Ensure the HVAC system is power is shut off from the circuit

breaker

2. If the labels on the PEK thermostat side (4 wires) labels are

missing, please label them with the stickers provided in the

box for your Wyze Thermostat.

3. Remove one wire at a time from the PEK and directly wire it to

the CWA.

● Y -> Y

● G -> G

● R -> R

● W -> W

4. Remove the PEK wires attached to the control board. This can

be done while simultaneously connecting the wires from the

CWA to the control board.

● Remove the PEK Y wire from the control board, then connect

the CWA Y wire to the control board.

● Remove the PEK W wire from the control board, then connect

the CWA W wire to the control board.

● Remove the PEK G wire from the control board, then connect

the CWA G wire to the control board.

● Remove the PEK C-wire from the control board, then connect

the CWA C-wire to the control board.

Thermostat:

From the thermostat wiring, the change is also simple. Label the PEK

wire as Y1.

For the rest of the installation, follow along in the Wyze app.

Installing a C-Wire Adapter

The C-wire Adapter (CWA) should be installed when your old

thermostat has no C-wire, but has at least a G and Y wire. Please

check the compatibility checker either online or in the Wyze app.

Step 1. Initial steps

Follow the initial installation guide in our Help Center until you reach

step 6, then return here for step 2 for the C-wire adapter.

Step 2. Make sure your HVAC system is off!

It Is very important that your system is off. We want you to be safe

when connecting wires at the control board. Ensure that your HVAC is

turned off at the circuit breaker or furnace.

Step 3. How to find your control board

Please locate your control board, it will be near your HVAC system,

usually in the basement. The HVAC control board is where the

thermostat wires connect to your heating and cooling system. In most

cases the control board can be found at your furnace or air handler. If

you have a furnace, you will need to open your system's cover.

The control board should look similar to the picture above. The control

board has wires with the same colours and thickness as the wires on

the thermostat. You will also find labelings similar to those at the

thermostat.

Step 4. Take a picture of your current control board wiring

Make sure you can see the terminal letters and identify the colour of

the wires in the photo.

Step 5. Label the wires

To install the CWA, you will need to disconnect the 4 wires (Y, G, R

and W) from the control board and connect them to the CWA. Label

the wires Y, G, R, and W. Note: If you don't have a W wire, the system

is still compatible. R can also be Rc.

Step 6. Disconnect the labeled wires from the control board

You may need to loosen the screw holding the wire to the control

board.

Step 7. Connect the labeled wires from the control board to the

CWA

Use the included screwdriver to tighten the screw after inserting each

wire to ensure it's securely connected.

Step 8. Connect the wires from the CWA to the control board

Match the wire to the control board terminal and make the connection.

Make sure to tighten the screw.

Step 9. You're all done! Replace any covers removed during the

installation

With the CWA installed, return to Step 6 of the installation instructions

in the Help Center to continue installing your thermostat.

Installing the C-Wire Adapter (CWA) when you have extra wires at

the control board

When installing the CWA module for Wyze Thermostat, the CWA will

need to be connected to the control panel. In some situations you will

find the control panel terminals have multiple wires connected as

shown below. The CWA will only need one wire from each terminal

(W-R-Y-G-C), as shown in the image to the right, the Y terminal has

two wires connected to it. To connect the CWA.

1. Identify which wire from terminal will be used for the CWA

1. At the thermostat identify the wire and colour of the

terminal we are looking into, in this case the Y-terminal

at the thermostat has a blue wire.

2. At the control board, the Y-terminal has a blue wire and

a white wire. In this case the blue wire at the control

board will be used for the CWA connection. Label the

blue wire with Y1 label provided in the box for Wyze

Thermostat.

3. Leave the remaining wire connected to the terminal, in

this case when connecting the CWA wires to the

control board, the white wire seen in the control board

will remain.

2. Continue with your CWA installation from the Wyze app.

Thermostat wires with no label

If one or more wires in your current thermostat doesn’t have a label,

don’t guess. You’ll need to know what wires are connected to your

current thermostat before you can install your Wyze Thermostat.

It's best that you check your system’s manual, contact an HVAC

professional, or look at your system’s control board.

Important: Most systems don’t use all the wires in the bundle coming

out of the wall. If any wires were not originally connected to your

current thermostat (and don’t have a label), they typically aren’t

connected to your system. There may be no need to connect these

wires to your Wyze Thermostat.

Determining a Conventional or Heat Pump (W or O/B)

Note: If you mistakenly chose the wrong terminal during setup, you

will need to reset the thermostat and select the correct terminal.

If you have the thermostat shown above it can be difficult to know

which wires to select in the Wyze app. Heat pumps live outside your

home and provide heating and cooling capabilities. That's where the

O/B terminal comes into play. If you have no equipment outside, you

definitely have a conventional system.

If you don’t know what system that you have off-hand, no worries!

Here are a few dead giveaways:

1. An easy way to identify a heat pump is to check on the control

board for the terminal labels. A heat pump will have O, B or

O/B terminals on the control board. Conventional units do not

usually have the O, O/B terminal.

2. Also, try turning on the heat, then check if your outside

condenser/air conditioning unit starts running. If it does, you

have a heat pump system.

3. If turning on the heat doesn’t make your outside unit run, you’ll

probably hear sound coming from your basement, a closet, or

the ceiling when your heat is on. This would mean you have a

conventional system.

4. Check the labels on your condenser or indoor air handler for a

model number or name. You likely can search this up to figure

out what type of system you have.

Determining the kind of heating system you have

During setup, Wyze Thermostat will ask what type of system you have

and the type of fuel it uses. It’s important that you enter the correct

system information during thermostat setup.

Wyze Thermostat needs to know the type of heating system you have

so it can correctly control it. To help you choose the system you have,

here’s a breakdown of how each system works.

Forced Air

With this kind of heating system, warm air

comes out of vents throughout your home.

Image

In-Floor

Radiant

This utilizes electric coils or hot water pipes

under the floor of your home to provide heating.

Image

Radiators

Radiators are sealed metal containers filled with

hot water, steam or electric coils.

They’re similar to in-floor systems, since they

don’t use vents or fans, but radiators aren’t

installed under the floor.

Image

My Thermostat isn’t turning on after installing (No

Power)

You must have a wire in both the Rc and C terminal. Follow the below

guide, before attempting to adjust any wiring ensure the power is shut

off at the circuit breaker. Use either the breaker box switch or Power

switch at the furnace to turn off the power before attempting to adjust

the wiring.

Regardless of with or without CWA, the wiring on Wyze Thermostat

must match one of the two images below.

1. Before checking/adjusting any wiring, check that power to the

heating/cool system is powered on. If it is, turn it off again

before checking/adjusting any wires.

2. Check your wiring. Please note that Wyze Thermostat power

configurations only support the two images shown above.

1. Important: Rh cannot be used independently, the Rh

will have to be changed to Rc. Note the above image.

2. To change Rh to Rc:

1. Turn off the heating/cooling system.

2. Disconnect the wiring from Rh.

3. Connect the wiring to Rc.

4. Power on the heating/cooling system.

3. Check the C-wire.

1. Turn off the power to your HVAC system.

2. The thermostat must have a C-wire. If you installed a

CWA, the old G-wire will become the C-wire. Don't

worry, you won't lose independent fan control.

3. Ensure C-wire and Rc-wire is properly installed at the

thermostat.

4. Sometimes the C-wire in your old thermostat is

unused, even if it is plugged into the C-terminal on your

old thermostat. If you have R (or Rc), G, W, Y (or Y1)

and unused C (or no power running through), you are

likely to fall into this case. To make it work, you can try

one of two ways:

1. Remove the C-wire at the thermostat, restart

the installation process without selecting

C-terminal and follow the app to install the

C-wire adapter.

2. Identify the C-wire coming from the thermostat

at the control board and wire it to the control

board C-terminal. Identifying the wire can be

challenging, we recommend the assistance of

an HVAC professional. Ensure the power is off

at the circuit breaker, before starting.

2. If you have installed C-Wire Adapter (CWA)

1. Turn Power off

2. Ensure C-Wire Adapter is properly installed

1. Review your photo of the old control board

wiring and ensure the labels were applied

correctly. Do you have an extra wire in one of

the control board terminals (R-G-W-C)?

2. Check that the correct wires are connected to

the CWA.

3. Double check the correct CWA wires are

connected to the control board.

4. Check all connections are secure and screws

are firmly tightened.

3. Check the equipment cover has been reinstalled (some

have kill switches there)

4. At the thermostat: If the C-Wire Adapter is installed, the

G-wire is used as the C-wire now. Ensure old G -> new

Heating or cooling system isn’t responding

If the thermostat is powered on and heating/cooling is engaged but

your HVAC system is not responding:

1. Turn off the power to the HVAC system.

2. Check your wiring at the thermostat, ensuring that each wire is

secure

○ Also check the wires at the control board, ensuring

each wire is secure

3. Turn the power back on and go through testing the system

(testing can be found under Settings > Advanced > System

Test).

4. If you continue to have issues, restart the reinstallation

process.

System Testing results are inaccurate

Upon completing testing, your system shows results similar to the

image below.

The system returns "Not Tested" even after being given a "Yes"

response during the testing phase. This is due to a communication

delay between Wyze Thermostat and the app. This result should

not raise any concerns and can be ignored.

Resolving Wire Detection Issues

The wire detection operation is completed when the device first turns

on.

Wire(s) not detected

1. Unplug the thermostat and check the wires.

2. Plug in the thermostat again. Wait ~2 minutes for the device to

reconnect to the server.

3. Connect the wire again, making sure the wire connection is

secure.

4. Go to the control board and verify that the wire is securely

connected.

○ Is there a wire not connected at the control board? This

wire is unused and can be removed from the

thermostat’s connections, and ignored in the wire

selection step during setup.

5. If the above suggestions do not work, skip the stage by

tapping on Try Again till the Skip option appears.

6. Follow the troubleshooting flowchart below if needed.

Extra Wire(s)

1. Unplug the thermostat and check the terminals showing extra

wire(s) to ensure that there is no wire or obstacle in the

terminal.

2. Plug in the thermostat again. Wait ~2 minutes for the device to

reconnect to the server.

3. Attempt the wire connection again.

4. If the above suggestions do not work, skip the stage by

tapping on Try Again till the Skip option appears.

Resolving WiFi Communication Errors

If your Wyze Thermostat has issues connecting to the Wyze app or

your WiFi network, try one of the following tips to resolve the issue:

1. Check your app version.

Make sure that you have the latest version of the Wyze app on your

phone or tablet. You can download it in the Apple App Store or Google

Play.

2. Make sure your home WiFi is online and working.

Since your thermostat uses your home’s WiFi network, check that you

can get online with another device in your home. If you can’t connect,

try using a different device to double-check. If you can’t connect to

WiFi with any device, contact your internet service provider to check

the service status in your area.

3. Check your SSID.

Unusual characters or spaces in your SSID can cause problems

during setup. Check the SSID (name) of your network. If it has special

characters or blank spaces before or after the name, rename the

network to something simpler. Once the device is online, update its

firmware. Once updated successfully, you should be able to set your

network back to its previous settings, then set the device back up to

see if your device will connect.

4. Restart your router

Restarting your router will reset your internet connection. You should

also restart any WiFi range extenders or repeaters. Here's how to

restart your router:

1. Unplug your modem and router power cords. You may have a

combination modem/router, or they may be separate devices.

All the lights on your modem and router should be off.

2. Wait for 30 seconds, then plug your modem and router back

in.

3. Your modem and router will restart. Wait a couple of minutes

or until you see steady power and connection lights. You may

also see a quickly flashing data light.

Note: Every router is different. You may need to consult your router’s

user manual for specific instructions on how to restart your router.

Once your router has been restarted, test the WiFi connection with a

computer or phone (make sure that cellular data is switched off). Then

try adding your Wyze Thermostat to the Wyze app again.

5. Reset your thermostat.

Reset your thermostat to its default settings. For more information and

instructions on resetting your thermostat, check out our Help Center.

You should also restart your phone or tablet and reopen the Wyze

app.

6. If the above steps don’t work, try connecting via mobile

hotspot. If you are able to connect with the mobile hotspot,

then your WiFi settings are not compatible with the thermostat.

Important: Make sure you have Bluetooth and WiFi enabled on your

phone or tablet before trying to add your thermostat again.

WiFi Compatibility:

1. Wyze Thermostat only supports 2.4 GHz bandwidth. Wyze

Thermostat does not support 5 GHz bandwidth.

2. Not compatible with Mesh WiFi.

3. Not compatible with a WiFi portal that requires a username

and password to access the Internet.

Resolving Bluetooth Pairing Issues

If you are unable to add your Wyze Thermostat to the app and

continue to see the page below after several attempts, follow the

following steps to troubleshoot.

1. Follow the instructions in the Help Center to reset your Wyze

Thermostat.

2. During setup in the Wyze app, tap Adding Your Thermostat.

3. Repeat from step 1 above. Remember to reset the device

each time. After 5 failed attempts, move on to step 4.

4. Try again with a new phone, then repeat from step 1.

Note: Once connected, you will still be able to control Wyze

Thermostat with your original phone.

5. If none of the tips above work, please contact Wyze Support.

Resolve Firmware Update Issues

If the thermostat is not working correctly after a firmware update, try

these tips before attempting to adjust any wiring:

1. Power cycle the thermostat. Unplug the thermostat from the

wall and plug it back in.

2. Factory reset the thermostat. Follow the instructions in the

Help Center for how to do this.

Handling Extra Wires

Extra wires are found exposed from the thermostat as shown in the

image below, and sometimes extra wires are found inside the wall

behind the thermostat. Usually, you can ignore the extra wires.

However if there is no C-wire in the C terminal, one of these extra

wires could be a potential C-wire. You will need to check where these

extra wires go at the control panel.

1. Follow the extra wire back to the control panel.

2. If the wire is unused at the control panel as well. (If the wire is

connected to another terminal but unused at the thermostat, it

can be disconnected).

3. Connect the wire to the C-terminal at the control board.

4. Label the wire at the thermostat as the C-wire.

Using the thermostat without the Wyze app

1. Single-press the knob on the thermostat to enter the control

menu.

2. Scroll the knob to the right to select State, Mode, Fan Control

or Settings.

3. Press the knob again to select the control you want.

Installing Wyze Thermostat on Dual Transformers

Some systems with heating and cooling are configured with a dual

transformer design. That means you have both Rc and Rh wires being

used, Rc = cooling side, Rh = heating side. As long as you have a C

terminal on the same board as Rc, your system is compatible with

Wyze.

There are four cases that you should be aware of:

1. C-wire coming from the Rc board.

2. C-wire coming from both Rc board and Rh board.

In both cases above, nothing needs to be done at the control board.

Please continue installation from the Wyze app.

3. C-wire is coming from the Rh Board: For compatibility with

Wyze Thermostat:

1. Remove the C-wire from the Rh board.

2. Connect the wire directly to the C terminal of the Rc

board.

4. No C-wires - In the case that you have no C-wire connected.

Review the image below for the modified CWA installation.

The CWA will be solely connected to the Rc board.

Note: If you open your thermostat wiring and see a jumper wire

between the Rc terminal and the Rh terminal, this is not a dual

transformer system.

Resetting your Wyze Thermostat

A: If you want to reset the device:

1. Press and hold the wheel/knob on the thermostat for 10

seconds.

2. Turn the wheel to select "Yes" to answer the question "This

will reset all settings, Continue?"

3. Push/press the knob to reset the thermostat.

Product FAQ

thermostat if you do not have a working WiFi.

Q: How do I set the Heat and Cool temperature in Auto Mode?

A. The minimum allowable temperature difference between heating

and cooling is 5 degrees fahrenheit (2.5 degrees Celsius). To set the

temperature for Auto Mode:

1. In the Wyze app, on the thermostat, tap either the Heat to or

Cool to on the thermostat main page to display the

temperature dial.

2. Swipe along the dial to the right or left to increase or decrease

the temperature setting.

Note: Always make sure the minimum temperature between Heat to

and Cool to is more than 5 degrees Farenheit to be able to increase

the “Heat to” temperature or decrease the “Cool to'' temperature.

Q: When does the next stage turn on?

A: The heat and cool stages change based on two factors; the

differential temp (set Temp - current temp), and default run time. After

the default run time, if the current temperature has not reached the set

temperature, the system will move to the next stage.

Stage 1: 1 - 5 degrees from the set temp.

Stage 2: 5 - 10 degrees from the set temp.

Stage 3: 10 - 15 degrees from the set temp.

Q: Can I set what stage will be used?

A: No. You can not manually set the heating or cooling stage to be

used by the system. See our Help enter for details on the various

stages.

Q: If wires are not automatically detected during the app setup,

how can I configure the wires manually?

The wire detection may not work well for some HVAC systems

because they do not provide feedback signals. If you are certain that

the wires are firmly inserted into the correct terminals, you can skip

the wire detection procedure by tapping Try Again twice. The app will

allow you to continue and test the system.

Q: How do I submit a log?

A: You can submit a log one of two ways. Through your Wyze

Thermostat’s app settings or through the Wyze app’s home page.

Submit the log and write down the Ticket ID to give customer support

Settings >Advanced >Temperature Correction.

Q: How do I change my WiFi?

A: You must reset the thermostat to change the WiFi it connects to.

Q: If I change addresses, what do I do?

A: Reset the device and delete it from your account in the Wyze app.

You must repeat the setup process at your new address.

Q: Does it have a heat anticipator setting?

A: No.

Q: What if I have a K Terminal and what do I do with it?

A: The K terminal located on the Honeywell thermostat combines the

Y and G wires. It does this using the Honeywell wiresaver. The Wyze

system is not-compatible with the Honeywell wiresaver. However your

system is compatible with Wyze Thermostat once the Honeywell

wiresaver is removed.

Please follow the following step to install your Wyze Thermostat.

1. Take photos of your control board, thermostat wiring and

Honeywell wiresaver.

2. Remove the Honeywell wiresaver.

At the Control Board

1. On the "Thermostat" side of the Honeywell wiresaver, label the

wires as follows.

1.1. Rc terminal -> Rc Label

1.2. K terminal -> Y Label

1.3. C terminal -> G Label

1.4. W-O/B terminal -> Please follow the W-O/B terminal

wire from the wiresaver to the control board. Label the

wire on the thermostat side of the wiresaver

corresponding to the terminal label found on the control

board. Note: If the control board also is labelled

W-O/B, you will need to determine if your system is a

heat pump system(O/B) or conventional (W).

2. With the wires correctly labelled, remove the wires from the

wire saver.

3. Remove the wires from the control board connected to the

wire saver.

4. Wire the labelled wires to their corresponding terminals on the

control board. Note: You may notice you no longer have a

C-wire. Don't worry, the app will walk you through setting up

the Wyze C-Wire Adapter.

5. Correct the thermostat wires.

At the Thermostat

1. Remove the thermostat cover panel (your wiring should be

similar to the wiring on the above left side photo).

2. To be compatible with Wyze Thermostat, wires K and C will

need to be adjusted.

3. Place the wire in the C terminal into the G terminal.

4. Place the wire in the K terminal into the Y terminal.

Your system is now compatible with Wyze Thermostat, please open

the Wyze app and add a new thermostat. Select the wires currently

connected in your system and the App will guide you through how to

connect the Wyze C-Wire Adapter.

Q: What do I do if I have GH and GC wires terminals at the

control board?

Some systems have GH and GC terminals on the control board with a

jumper wire between R and GH. The GH provides low fan speed

during heating, while the GC is for high fan speed during cooling.

1. Disconnect the wire connected to GH and connect it to R.

2. Disconnect the jumper wire between R and GH.

3. Connect a jumper wire between GH and W.

4. Install the CWA if there is no C-wire at the thermostat.

5. When choosing the type of heating system, choose radiator or

in-floor radiant.

Q: Why won't the heat turn off?

A. Example: Your heat won't turn off after reaching the set

temperature, and the room gets too hot. Here are some things that

could cause that problem:

1. The thermostat might have been configured incorrectly.

For instance, if the system is a conventional unit but you

configure it as a heat pump. Verify the kind of system you are

using (Heat pump or Conventional unit) and make sure that

you wired the system correctly.

2. In some cases, the temperature will go up about 2 to 4

degrees higher than the set point temperature because the

residual heat from the furnace causes the temperature in

the room to rise till it dissipates, even after heating has

stopped. Set the thermostat heating 2 to 3 degrees below the

preferred set point if you realise this situation.

2. The thermostat or its wires have been damaged and are

not reliably signaling the heating system primary controller. For

example, an internal relay is sticking and keeps heat on even

after the thermostat has sent a signal to shutdown heating.

3. The thermostat is being blocked from properly sensing

room heat. That could be due to the movement of the warm

air supply registers to a new, more distant location, or more

often, due to furniture, drapes, or even dust that blocks the air

inlet openings around the thermostat that allow it to sense

room temperature. This results in the thermostat inaccurately

sensing the temperature in the room.

4. The thermostat is located on a cold outdoor wall or where

cold air blows on it. However, if your thermostat was not

moved and is on an interior wall and in a draft of cold air, this

isn't likely to be the cause of your issue.

Q: What can cause the thermostat fuse to blow?

A. Some of the reasons why the thermostat fuse will blow or emit

smoke are:

1. The voltage from the C terminal of your control board is higher

than 28 VAC. Currently, Wyze Thermostat only supports

voltages lower than 28 VAC and as such voltages equal and

above 28 VAC will cause the fuse to blow.

2. A short circuit between Rc and C on the thermostat will also

cause the fuse of the furnace to blow. This is a rare case

caused in the manufacturing process.

3. The fuse of the furnace will blow if you mistakenly connect the

RC wire to the Rc terminal and the C-wire to the Rh terminal.

Always make sure you are connecting the right wires to the

right terminals.

Q: Why does my Furnace fuse keep blowing?

A. Under normal circumstances, a well installed thermostat will not

cause the furnace fuse to blow. However, this may happen if there is a

short circuit between any of the wires and C. For example, if the W1

wire and the C-wire are touching each other, then there will be a short

circuit whenever the thermostat calls for heat, resulting in the fuse of

the furnace to blow. To resolve this, check your wirings to ensure that

you do not have any exposed wires touching each other.

Q: Why does my temperature settings and schedule keep

changing?

A. Your temperature settings or schedule may change if there is a

switch between states. Any change in State (Home, Away, Sleep)

during a schedule will result in the schedule being canceled. The

temperature preference is the basic temperature setting for the

thermostat. Changing states (Home, Away or Sleep) during a

schedule will cancel the schedule at that particular time. The

temperature for the temperature preference will then be activated.
