Thermostat Installation
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.
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.
Step 1 Step 2
Make sure your
old thermostat
Does Not Contain
Line Voltage Wiring
If you see any of these wire nuts,
unfortunately the BCC110 may not work
with your system. If you are unsure or
would like to discuss your options, please

WARNING: Failure to turn off the power may
result in electrical shock and/or damage to the
equipment.
