Heat Pump Connections
If you do not have a heat pump system, refer
to fi gures 2 & 3.
Refer to equipment manufacturers' instructions
for specifi c system wiring information.
You can confi gure the thermostat for use with
the following heat pump systems.
HEAT PUMP TYPE 1 (HP 1).
compressor system; gas or electric backup.
HEAT PUMP TYPE 2 (HP 2).
compressor or two compressor system with
gas or electric backup.
After wiring, see INSTALLER CONFIGURA-
TION section for proper thermostat confi gura-
tion.
Single Stage and Multi-Stage Con-
nections
Refer to equipment manufacturers' instructions
for specifi c system wiring information.
This thermostat is designed to operate a
single-transformer or two-transformer system.
You can confi gure the thermostat for use with
the following fossil fuel systems:
SINGLE STAGE (SS 1)
gas, oil or electric.
MULTI-STAGE (MS 2)
gas, oil or electric.
After wiring, see INSTALLER CONFIGURA-
TION section for proper thermostat confi gura-
tion.
NOTE: If continuous backlight or hard-
wired power input are desired but do not
function in both HEAT and COOL modes,
cut the heating transformer 24V wires
and tape off. Connect the neutral circuit
disconnected from the heating trans-
former to the neutral circuit of the cooling
transformer. Disconnect the wire to the
RH terminal and install a jumper between
RH and RC. Depending on the system
requirements, replace the cooling trans-
former with a 75VA class II transformer if
needed.
