Installing a Thermostat

To install your new XFINITY Home Thermostat:


Don’t forget!
These instructions help you connect your new Thermostat to your home's electrical and heating and cooling systems. You will still need to pair your Thermostat with your XFINITY Home system, which you can do either before or after installation.

Remove Your Old Thermostat

Warning! At your electrical circuit breaker panel, turn off the electricity to the heating, ventilation and cooling (HVAC) unit.

  1. Remove the cover from your existing Thermostat.
  2. Make a note of the location of each wire connected to the Thermostat wiring terminals. As you identify each wire (Fan, Common, Cool Control, etc.), attach the included adhesive labels to each wire before you disconnect the wire from the terminal.
    • Tip! Use your mobile device to take a picture of the current wiring for reference.
  3. Remove each wire from the Thermostat wiring terminal, making sure to secure the wire so that it doesn't fall back into the wall. Wrapping each wire around a pencil works well. Leave at least three inches of wire for each connection.
  4. Once all wires are removed from the wiring terminal, remove the Thermostat from the wall.
  5. Optional: Remove one-eighth of an inch of insulation from the end of each wire.
