Make sure your Heater/Air Conditioner
is working properly before beginning
installation of the thermostat.
Carefully unpack the thermostat.
Save the screws, bracket, and
instructions.

Remove the cover of the old thermostat.
If it does not come off easily check for
screws.
Loosen the screws holding the thermostat

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 thermostat.
Keep the old thermostat for reference
purposes, until your new thermostat is
functioning properly.
