Assemble tools: Flat blade screwdriver, wire cutters and wire
strippers.
Carefully unpack the thermostat. Save the screws, any brack-
ets, and instructions.
Make sure your Heater/Air Conditioner is working properly
before beginning installation of the thermostat.
Turn off the power to the Heating/Air Conditioning system at
the main fuse panel. Most residential systems have a separate
breaker for disconnecting power to the furnace.
To install the thermostat properly, please follow these step by
step instructions. If you are unsure about any of these steps,
call a qualified technician for assistance.

Remove the cover of the old thermostat. If it does not come off
easily, check for screws.
Loosen the screws holding the thermostat base or subbase to the
wall and lift away.
Keep the old thermostat for reference purposes, until your new
thermostat is functioning properly.
Disconnect the wires from the old thermostat. Tape the ends
of the wires as you disconnect them, and mark them with the
letter of the terminal for easy reconnection to the new thermo-
stat.
