SECTION 2
Remove & Replace the Old Thermostat
2
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 
thermostat.
