1. Press SYSTEM button to select the Flame icon Flame icon Flame icon Flame icon Flame icon ( ). If
the auxiliary heating system has a standing pilot, be sure
to light it.
2. Press to adjust thermostat setting to 1° above room
temperature. The heat pump system should begin to
operate. The display should show STG1. However, if the
set point temperature display is flashing, the compressor
lockout feature is operating (see Configuration menu,
item 5).
3. Adjust temperature setting to 3° above room temperature.
If your system configuration is set at MS2, HP2 or HP1,
the auxiliary heat system should begin to operate and the
display should show STG 1+2.
4. Press to adjust the thermostat below room tempera-
ture. The heating system should stop operating.

EMER bypasses the Heat Pump to use the heat source
wired to terminal E on the thermostat. EMER is typically
used when compressor operation is not desired, or you
prefer back-up heat only.
1. Press SYSTEM button to select EMER. EMER will flash
on the display.
2. Press to adjust thermostat setting above room
temperature. The Aux. heating system will begin to
operate. The display will show STG1 flashing EMER
and flame icon ( ) to indicate that the Aux. system is
operating.
3. Adjust temperature setting to 3° above room temperature.
The auxiliary heat system should begin to operate and the
display should show STG 1+2.
4. Press to adjust the thermostat below room tempera-
ture. The Aux. heating system should stop operating.

You can configure the thermostat for use with either multi-stage
electric heat systems or multi-stage gas systems. When con-
figured for electric
electric electric electric electric heat, the G G G G 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 transformer with
a 75VA Class II transformer. After disconnecting one trans-
former, the two commons must be jumpered together.
Use the terminal output information below to help you wire the
thermostat properly for your multi-stage system. After wiring,
