Installation Precautions  

•

•

•

Before installing the Smart Thermostat or servicing the  

HVAC equipment, turn off power to the system.  

Leave power off until you have finished installing or  

servicing the HVAC equipment.  

Shorting the electric terminals at the control on the  

heating or cooling system is not recommended. Do not test  

the system this way.  

•

When testing the existing system or the new Smart  

Thermostat do not run the cooling system when it is cold  

outside as this may harm the compressor.  

•

•

•

Please wait for mild temperatures before testing the  

cooling system.  

You must follow all local codes and ordinances for wiring  

the system.  

This thermostat should only be powered by 4 AA alkaline  

batteries or a listed Class 2 power supply at 24 VAC  

(C-Wire or wall transformer)  

•

An amperage higher than 1 amp to each thermostat  

terminal may cause damage to the thermostat. Verify that  

the system is 24 VAC. If the old system is labeled as 120 V  

or 240 V or has wire nuts, the system is high voltage. Do  

NOT install this thermostat on a high voltage system.  

Contact a local HVAC professional for help.  

•

Before installing the Smart Thermostat or servicing the  

HVAC equipment, turn off power to the system.

Installation Considerations  

Location  

•

•

If replacing an existing thermostat, the new Smart  

Thermostat can be mounted in its place.  

If a new location is desired it will be necessary to move the  

wiring. New installations and relocations should follow the  

accompanying guidelines to ensure the most accurate  

temperature reading and ease of use.  

•

•

Mount on an inside wall, approximately 5 ft. (1.5 m) above  

the floor in a frequently used room.  

Avoid areas that are exposed to large temperature  

variances, such as: direct sunlight, near an AC unit, above  

or below auxiliary heat and air vents, and drafts from  

windows or exterior doors. Be aware of what is on the  

other side of the wall where the installation is occurring.  

Do not install on walls adjacent to unheated rooms, stoves,  

or housing hot water pipes. Exterior walls are also not ideal  

locations for installation.  

•

•

Damp areas will not only affect the humidity reading but  

could lead to corrosion and shorten the lifespan of  

the thermostat.  

Install in a location with good air circulation. Stagnant air  

will not accurately reflect the rate of temperature change  

in the room.  

•

•

Avoid areas behind open doors, corners, and alcoves.  

Wait until construction and painting are finished  

before installing.  

Preparation  

❶ If you will add the Smart Thermostat to a Z-Wave network,  

power on the controller and verify it is communicating.  

•

If the Z-Wave network supports SmartStart, use MobileTech  

to scan the QR code found on the Thermostat or the box.  

❷ Test the existing system.  

•

Verify that the heating and/or cooling system is operating  

properly before you try to install the new Smart Thermostat.  

CAUTION: Do not test the system by shorting electric  

terminals. Do not test the cooling system if it is cold outside,  

as this may harm the compressor.  

❸ Turn off power to the HVAC unit.  

•

Turn all heating and cooling systems off. This can be done at  

the circuit breaker.  

CAUTION: Do not remove the existing thermostat until  

power has been turned off at the circuit breaker.  

❸

❹ Remove the existing thermostat.  

•

•

Remove the cover from the existing thermostat. Do not  

disconnect the wires yet.  

Make sure the wires are identified correctly. If you have an  

unidentified wire, it may be necessary to identify where the  

wire connects to the heating or air conditioning equipment.  

CAUTION: Wiring can vary for each manufacturer. Identify  

all wiring designations before removing it from the  

existing thermostat.  

•

•

Take a picture of the wires before you detach them from the  

existing thermostat for future reference.  

After all wires are identified and a picture has been taken,  

disconnect all the wires and remove the existing thermostat.  

Remember to secure the wires so they do not fall into  

the wall.  

❺ Prep wires (if needed)  

•

•

Ensure the wires are a proper gauge between 16-24 AWG  

(1.3 – 0.5 mm)  

Make sure wires have exposed straight ends of the  

appropriate length.  

Thermostat Installation  

❶ Level and mount the backplate to the wall with  

supplied hardware.  

❷ Insert wires into their designated terminals. See table  

for details.  

•

•

If you have R, connect to RC  

If you have RH and RC, remove the black jumper in the  

top-right corner of the backplate. See the graphic  

for details.  

•

•

Z can be used for the following options: W2, Y2, H, DH, O/B  

Zoning or Ventilation  

If you have extra wires, do not install them in the new  

thermostat. Please contact your local HVAC professional  

for additional assistance  

CAUTION: Do NOT insert more than one wire to a terminal.  

❸ Add batteries to the Thermostat (4x AA)  

❹ After all wires are in their final locations, restore power to  

the HVAC system  

❺ Connect the Thermostat to the Back Plate  

❻ Follow the on-screen setup instructions to configure the  

thermostat and connect it to a Z-Wave network.  

The Smart Thermostat will automatically detect  

connected wires.  

Follow the on-screen instructions to complete the  

thermostat configuration.  

CAUTION: If the thermostat screen does not show all the  

connected wires, remove the thermostat from the wall and  

verify that all wires are properly connected. If issues persist,  

there may be a problem with automatically detecting your  

wiring. See invalid wiring in the Troubleshooting section.  

Setup  

Depending on the system type and configuration, the  

thermostat may request the following information  

during setup:  

Heat Type: Tells the thermostat whether it should turn on  

the fan during a heating cycle.  

•

•

•

•

•

Forced air heating: Electric  

Radiant floor heating: Fossil  

Fossil/electric baseboard heating: Fossil  

Radiators: Fossil  

If unsure: Unsure  

Backup Heat Type: Tells the thermostat what type of  

auxiliary/backup heating the heat pump uses.  

•

•

Electric: This is the most common type of backup heating.  

Dual Fuel: Some heat pumps use a fossil furnace (for  

example, natural gas, oil, or propane) for backup heating.  

•

If unsure: The system will automatically detect which heat  

type is appropriate for your system.  

Z-Terminal: A “dynamic” terminal that can be used for a  

variety of different system functions. If using the Z  

terminal, you must specify its function.  

Note: Z uses the RC power and W2 is not available in a dual  

power system configuration where the RC-RH jumper is  

removed. Accessories powered by the transformer connected  

to RH will not operate if the RC-RH jumper is removed.  

W2: Second stage of heat or aux  

Y2:  

H:  

Second stage of cool or heat pump  

Humidifier  

DH: Dehumidifier  

EX:  

Ventilation (HRV, VRV, air baffle)  

Test the System  

CAUTION: Do not test the cool mode during cold weather.  

Wait for mild weather to fully test the system.  

•

•

After successfully installing and setting up your new Smart  

Thermostat, please test the Smart Thermostat and  

HVAC system.  

If the Smart Thermostat will control a heating system, test  

the heating system by changing the mode to HEAT and  

adjusting the setpoint to be higher than the current room  

temperature. Verify the heating system turns on and that  

the room is starting to warm up.  

•

If the Smart Thermostat will control a cooling system, test  

the cooling system by changing the mode to COOL and  

adjusting the setpoint to be lower than the current room  

temperature. Verify the cooling system turns on and that  

the room is starting to cool down.  

Operation  

❶ Press any button to wake up the thermostat  

❷ After waking, the display will show the current mode and  

ambient temperature. Setpoint is only in Heat/Cool mode.  

❸ The display will turn off after 10 seconds to conserve  

energy. The thermostat will continue to operate while the  

display is off.  

Changing the mode and setpoint  

❶ Press the Menu (icon) button  

❷ Select Mode menu item  

❸ Select desired mode  

•

•

•

The modes are Heat, Cool, Auto, Emer and Off.  

Emer mode is available for Heat Pump systems.  

When in Emer mode, the display will read EMER when the  

thermostat wakes up.  

•

In Auto, the active setpoint is indicated by the operating  

state above the ambient temperature. The buttons on the  

display will also be illuminated to indicate the active  

setpoint. The LEDs will be illuminated red when heating is  

active and blue when cooling is active.  

Using and Changing  

the Batteries  

If the thermostat batteries are low, replace the batteries  

with four new AA batteries.  

❶ Remove the thermostat from the back plate by pulling the  

thermostat straight out and off the wall.  

❷ Take out the existing batteries.  

❸ Insert the new batteries following the specified polarity  

markings on the thermostat.  

❹ Return the thermostat to the Back Plate by pressing the  

thermostat body firmly into the back plate mounted to the  

wall. Ensure that the pins on the body are correctly aligned  

with the back plate. Failure to do so could cause damage  

to the thermostat.  

Battery Advisory  

Always replace the batteries as soon as you have low  

battery levels, indicated by “LOW” then “BATT” flashing on  

the thermostat. If the batteries drain, the thermostat  

could leave the HVAC system on or off, overheating or  

freezing the home.  

•

•

Always replace the batteries at least once a year. This will  

protect the thermostat from damage and corrosion by  

leaking batteries.  

If the home is unoccupied for a month or more, such as  

with vacation homes, you should replace the batteries as a  

preventive measure against battery failure while you  

are away.  

•

Always use new batteries as replacements.  

Humidity Control  

The thermostat can adjust the humidity level in your home  

by directly controlling an external humidifier, dehumidifier,  

or by using the cooling system to dehumidify. For an  

external humidifier or dehumidifier, the thermostat must  

be configured to use the Z terminal. For controlling  

dehumidification by the cooling system, a cooling system  

must be present without an external dehumidifier. In this  

case, the thermostat will extend your cooling cycles to  

reach your dehumidification setpoint. To change  

humidification/dehumidification settings refer to the  

Customer Website.  

Ventilation  

The thermostat can control a ventilation system (HRV, VRV,  

or air baffle) using the Z terminal. By default, the  

thermostat will operate the ventilation system for 15  

minutes every hour. To change the ventilation settings,  

refer to the advanced configuration settings through the  

Customer Website or Mobile App. If the settings are not  

available, please contact your service provider.  

Additional Configuration  

Although the default settings will be appropriate in most  

cases, you also have the option to change all configuration  

settings via the Display. Open the Settings menu and  

proceed to the relevant settings.  

CAUTION: Be careful when changing advanced configuration  

settings. These configuration settings should only be  

changed by those familiar with heating and cooling system  

parameters. Contact your local HVAC professional for help.
