Refer to equipment manufacturers'
instructions 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.

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.
