STEP 2. POWER OFF YOUR HEATING AND
COOLING SYSTEM
Turn off the power to your heating and cooling system. You can
do this either at your circuit breaker box or a switch at your
indoor furnace or fan coil. Most systems have one switch, but
systems with Rh, Rc, and C wires noted in Step 1 will have two
switches.
Make sure your system is without power by using your old
thermostat to adjust the temperature. Your system should not
turn on.
