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.
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.
Proper installation of the thermostat will be 
accomplished by following these step by step 
instructions.  If you are unsure about any of these 
steps, call a qualified technician for assistance.
