Refer to equipment manufacturers'
instructions 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 heat
(W1, W2) and cool (Y1); 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 trans-
former with a 75VA Class II
transformer. After disconnecting one
transformer, the two commons must
be jumpered together.
