Install your thermostat

Switch OFF power to your heating/cooling system

Important!

To protect your equipment, switch OFF the power to your heating/cooling system at the breaker box or the system switch.

Confirm power is OFF

Try to turn on the heating/cooling equipment by changing the temperature on your old thermostat. Your power is OFF if your system does not turn ON.
This thermostat works with common 24-volt systems such as forced air, hydronic, heat pump, oil, gas, and electric. It will not work with millivolt systems, such as a gas fireplace, or with 120/240-volt systems such as baseboard electric heat.

Remove old thermostat faceplate and leave wires connected

Take a picture of the wire connections for later reference.

If no wire is connected to a terminal labeled C or no C terminal exists on the old thermostat, view the Alternate Wiring videos at wifithermostat.com/videos.

Important! C wire is required and is the primary power source for your thermostat. Without a C wire, your thermostat will not power up.

Note: If you have an older thermostat with a sealed mercury tube, see the warning page for proper disposal instructions.

Label wires

Do not label by wire color. Use the supplied sticky tags to label each wire as you disconnect it. Label wires according to old thermostat terminal designations, not by wire color.
Note: If no tag matches a terminal designation, write the appropriate letter on a blank sticky tag.

Remove wallplate

Remove the old wallplate from the wall after all wires are labeled and disconnected.

Separate Wi-Fi thermostat and its wallplate

On your new thermostat, grasp the finger holds on the top and bottom of the wallplate with one hand and the thermostat (front) with the other hand. Pull pieces apart.

Mount wallplate for Wi-Fi thermostat

Mount your new wallplate using screws and anchors included with the thermostat.

If necessary:

Drill 3/16-in holes for drywall.
Drill 7/32-in holes for plaster.

Note: You may be able to use your existing wall anchors. Hold the wallplate up to the existing anchors to check for alignment.

If your system is:

Multistage equipment
Any type of heat pump
Hydronic
Other

You MUST change the system type by setting system function 0170.

Test your thermostat

Touch the SYSTEM button to change to heating or cooling and begin operation. Heating/cooling system not turning on? Refer to the User Guide or FAQ at http://wifithermostat.com/support
