Heat Pump Terminal Outputs - White Rodgers 1F95-391 Installation & Configuration Manual

MULTI-STAGE TERMINAL OUTPUTS
Refer to equipment manufacturers' instruc-
tions for specific system wiring information.
You can configure the thermostat for use
with either multi-stage electric heat systems
or multi-stage gas systems. When configured
for electric heat, the G terminal (blower/fan)
will be energized on a call for heat.

HEAT PUMP TERMINAL OUTPUTS

Refer to equipment manufacturers' instruc-
tions for specific system wiring information.
You can configure the thermostat for use
with the following heat pump system types:
HEAT PUMP TYPE 1. Single-stage
compressor system; gas or electric backup.
HEAT PUMP TYPE 2. Multi-stage or two-
compressor system; gas or electric backup.
HEAT PUMP TYPE 3. System requiring
separate signals for compressor heat (W1)
and cool (Y1); with gas or electric backup.

This thermostat is designed to operate a
single-transformer system. If you have a two-
transformer system, cut and tape off one
transformer. If transformer safety circuits are
in only one of the systems, remove the
transformer of the system with NO safety
circuits. If required, replace remaining
transformer with a 75VA Class II transformer.
After disconnecting one transformer, the two
commons must be jumpered together.
