Thermostat Installation

Step 1
Turn OFF power
Turn off all power to your
HVAC (Heating, Ventilation,
and Air Conditioning) system
by using the master
equipment switch or
circuit breaker box.
WARNING: Failure to turn off the power may
result in electrical shock and/or damage to the
equipment.
Confirm that your system is off
One way to do this is to try to adjust the temperature on
your old thermostat. If you don't hear the system turn on
within 5 minutes, air does not come out from the vents
or the old thermostat does not even power on, then you
have successfully turned off the power to your system.
