tion (see
TESTING YOUR
THERMOSTAT
).
CAUTION
Method 2. (For heat-only or heat/cool
systems.)
This installation requires an
additional wire that will run
from the furnace low voltage
terminal block to the thermostat.
1. Disconnect 120v AC power from
system.
2. Attach a wire to terminal C on the
furnace low voltage terminal block.
Attach the wire’s other end to the
resistor using a wire nut connector.
Attach the resistor to the W terminal
