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.

STEP 3. REMOVE YOUR OLD THERMOSTAT
Using your old thermostat as a guide, use the provided wire
labels to identify each wire. Don’t worry about any
non-connected wires.
Disconnect each wire. Most thermostats’ wires are connected
using screws; simply loosen each screw with a screwdriver.
Remove your old thermostat base by unscrewing it from the
wall. Be careful not to let any wire labels fall off or wires fall
back into the wall.
Discard any jumper wires
or brackets between Rh, Rc, or R
