Level (optional)
Pencil
Drill bit (3/16” for drywall, 7/32” for plaster)

Remove your old thermostat

Turn off power at heating/cooling system (or fuse/circuit-breaker panel).
Remove cover and thermostat, but leave wallplate with wires attached.

MERCURY NOTICE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact your local waste management authority for instructions regarding recycling and proper disposal.

Did you purchase right thermostat? Count wires to check.

Count the number of wires coming out of the wall and attached to terminals in your old thermostat. If any of them are attached to a terminal marked “C” or “C1” do not count that wire in your total.
If the total (not counting C or C1) is 2 wires, proceed to the next page. If you have 3 or more wires, your new thermostat may not be compatible with your system. Stop installation and call 1-800-468-1502 for advice.

Label wires and remove old wallplate

Use a screwdriver to disconnect wires one by one.As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your thermostat package.)
Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening.
