Wiring
1 Loosen screw terminals, insert
wires into terminal block, then
re-tighten screws.
2 Push excess wire back into the
wall opening. Keep wires in shaded
area as shown at left.
3 Plug the wall opening with non-
flammable insulation to prevent
drafts from affecting Comfort
Control operation.
Heat/Cool
Heat Pump
NOTES
R & Rc terminals
In single-transformer system, leave metal
jumper in place between R & Rc. Remo
ve
metal jumper if two-transformer system.
B terminal
B is the common wire terminal.
W (O) terminal
If Comfort Control is configured for a heat
pump in the Installer Setup, changeover valve
is configured for cool (“O” factory setting).
F terminal (Output)
Heat pump reset. F ter
minal po
wered continu-
ously when Comfort Control is set to Em Heat.
Configure Comfort Control for 2 heat/1 cool
heat pump in the Installer Setup
.
Wire specifications
Use 18- to 22-gauge Comfor
t Control wire
.
Shielded cable is not required.
Keep wires in this
shaded area
CAUTION: ELECTRICAL HAZARD. Can cause electrical shock or equipment damage.
Disconnect power before wiring.
