Choose the Fan Setting (Auto or On or Prog)
There are two fan features
1. Fan Auto/On - Traditional Fan Settings
Press Fan to select Auto or On. The most commonly
used setting is Auto. Fan Auto runs the fan only when the
heating or cooling system is operating. Selecting Fan On
runs the fan continuously for increased air circulation or to
allow additional air cleaning if the system is equipped with
an Electronic Air Cleaner.
Heating
1. Press SYSTEM key to select HEAT. If the auxiliary heating
system has a standing pilot, be sure to light it.
2. Press
to adjust thermostat setting to 1° above the
room temperature. The heat pump system should begin
to operate. The display should show "System On".
However, if the system configuration is set to HP1 or
HP2 and setpoint temperature display is flashing, the
5 minute compressor lockout feature is operating (see
Configuration menu, item 11).
2. FAN Prog - Comfort Circulating fan Feature
Pressing Fan until FAN Prog appears activates the
Comfort Circulating Fan Option. This causes the
thermostats to cycle the fan on for 10 minutes and off for
20 minutes if the thermostat has not called for heat or
cool during the past 60 minutes. This assures moderate
air circulation even when the heating and cooling
equipment is not cycling.
3. Adjust temperature setting to 3° above room temperature.
If your system configuration is set at MS2, HP1 or HP2,
the auxiliary heat system should begin to operate and the
display will show "System On +2".
Choose the System Setting

Emergency Heat (System EM Position) bypasses the Heat
Pump to use the heat source wired to terminal W/E, W2
on the thermostat. EM is typically used when compressor
operation is not desired, or you prefer back-up heat only.
Em: Setting is available only when the thermostat is
configured in HP1 or HP2 mode.
Auto: Auto Changeover is used in areas where both heating
and cooling may be required on the same day. AUTO allows
the thermostat to automatically select heating or cooling
depending on the indoor temperature and the selected heat
and cool temperatures. When using AUTO, be sure to set the
Cooling temperatures more than 1° Fahrenheit higher than
the heating temperature.
1. Press SYSTEM key to select EM. “EM Heat Mode” will
flash on the display.
2. Press
to adjust thermostat setting above room
temperature. The Emergency heating system will begin to
operate. The display will show “System On” flashing “EM
Heat Mode” and “Heat” to indicate that the Emergency
system is operating.
