Installation Instructions
Remove and Replace the old thermostat
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.
• Assemble tools: Flat blade screwdriver, wire cutters and wire
strippers.
• Make sure your Heater/Air Conditioner is working properly
before beginning installation of the thermostat.
• Carefully unpack the thermostat. Save the screws, any brackets,
and instructions.
• 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.
• 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.
• If you have a smart phone handy, take a photo of the wiring for
future reference.
• Disconnect the wires from the old thermostat. Tape the ends of
