Remove the Old Thermostat
Before removing the wires from the thermostat or wall
plate, take a photo of all wires for reference, then label
each wire according to the terminal codes.
Disconnect the wires from the old thermostat one by one.
Do not let wires fall back into the wall. Remember, the
power to your HVAC system must be turned off.
Note: After labeling the wires, we recommend
securing them to an object such as a pen or clip to
prevent them from falling back into the wall.
POWER OFF WARNING
Failure to turn off power may result in
electrical shock and/or system damage.
