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

Honeywell Smart Color Thermostat FIG 1

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

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. Wrap the wires around a pencil to prevent them from falling back into the wall.

Mount wallplate for 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.
