Install your thermostat
Switch OFF power to your heating/cooling system
- Important! To protect 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 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 the old thermostat faceplate and leave the 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.
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 the old wallplate from the wall after all wires are labelled and disconnected.

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

Determine your heating/cooling system type
Important! The heating/cooling system type must be set so that your thermostat operates properly and does not damage your system.
If you have a traditional system (single-stage heating and cooling), your thermostat is set up by default to control this system. However, you will still need to connect your thermostat to a Z-Wave network. To do this, enter the system setup (see step 2.1) and then proceed to Step 3.
If you DO NOT have a single-stage heating and cooling system, You MUST change the system type by setting system function 0170. See page 40 in the
User Guide for a list of options. Go to Step 2
