NOTES
R & Rc termirtals
In single-transformer system, leave metal
jumper in place between R & Rc. Remove
metal jumper if two-transformer system.
C terminal
The C (common wire) terminal is optional
when thermostat is powered by batteries,
W(O/B) terminal
If thermostat is configured for a heat pump
in the Installer Setup, configure changeover
valve for cool ("O" factory setting) or heat
("B").
L terminal (Output)
Heat pump reset. L terminal powered contin-
uously when thermostat is set to Em Heat.
Configure thermostat for 2 heat /1 cool heat
pump in the Installer Setup.
Wire specifications
Use 18- to 22-gauge thermostat wire.
Shielded cable is not required.
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.
Plug the wall opening with non-
flammable insulation to prevent
drafts from affecting thermostat
operation.
