1 Install your thermostat

1.1 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 heating/cooling equipment by changing temperature on your old thermostat. Your power is OFF if your system does not turn ON.

Diagram Description: Shows a circuit breaker box with the door open, illustrating where to switch off power, and a separate heating/cooling system power switch.

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.

1.2 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.

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

Diagram Description: Shows a close-up of old thermostat wiring terminals labeled R, Rc, G, W, Y, C, illustrating how wires are connected.

1.3 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.

Diagram Description: Shows sticky tags being applied to wires, with examples of wiring labels (e.g., G, W, Y, R, C) and terminal designations.

1.4 Remove wallplate

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

1.5 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.

Diagram Description: Illustrates how to separate the thermostat unit from its backplate by pulling at designated finger holds.

1.6 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.

Diagram Description: Shows the new wallplate being mounted to the wall with screws and anchors, with wires passing through.

1.7 Connect wires

Starting with the C Wire, match the sticky tag on the wire to the terminal labels.

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

• Loosen screw, insert wire on inside edge of terminal, then tighten screw.
• Verify wire is firmly secured by gently pulling on wire.
• Repeat steps 1.7a-1.7c for all other wires.
• Push any excess wire back into the wall opening after all wires are installed.

Note: The wiring for your application might be different from the wiring shown above. Remove metal jumper only if you have both R and RC wires.

Diagram Description: Shows two terminal block configurations: one for conventional systems (with R and RC jumper) and one for heat pump systems. Labels like G, W, Y, R, C, K, L, AUX/E, O/B are visible.

❓ Labels don't match or have heat pump system? See User Guide.
