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.

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

electric heat, the 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,
