If you are unsure of what type of system you have, seek
professional installation.

Step 1 Power Off Current System
1) Go to your home’s circuit breaker panel and
switch the furnace and AC breakers off.

system, adjust the temperature on your
current thermostat. If system does not
respond accordingly, power has successfully
been shut off.

small screws that will need to be removed.
Step 3 Label and Disconnect Wires
TIP: If you see large thick electric
wires, wire nuts, or if your system
is labeled 120V or 240V DO NOT
PROCEED. CALL A PROFESSIONAL
LICENSED HVAC SPECIALIST.
