If at any time during testing your system does not operate 
properly, contact a qualifi ed service person.

If your system does not have a G terminal connection, skip to 
Heating System.

1.  Turn on power to system.
2.  Press FAN button. The display will show "Fan" and the    
 

blower should begin to operate.

3.  Press FAN button again. The display will show "Fan" out- 
 

lined and the blower should stop immediately. 

1. Press the HEAT button 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 room 

temperature. The heat pump system should begin to 
operate. The display should show “Heat”. However, if the 
system confi guration is set to HP1 or HP2 and setpoint
temperature display is fl ashing, the 5 minute compressor
lockout feature is operating (see Confi guration menu,
item 7).

3. Adjust temperature setting to 3° above room temperature.

If your system confi guration is set at MS2, HP2 or HP1,
the auxiliary heat system should begin to operate and
the display will show "Aux" and "Heat".

4. Press 

 to adjust the thermostat below room tempera-

ture. The heating system should stop operating.

AUX bypasses the Heat Pump to use the heat source wired 
to terminal W/E on the thermostat. AUX is typically used 
when compressor operation is not desired, or you prefer 
back-up heat only.

1.  Press and hold HEAT button for at least 5 seconds to 

select "AUX".

2. Press 

 to adjust thermostat setting above room tem-

perature. The Auxiliary heating system will begin to oper-
ate. The display will show “AUX” and “HEAT”.

3. Press 

 to adjust the thermostat below room tempera-

ture. The Auxiliary heating system should stop operating.

4. To return to Heat Pump mode press “HEAT” button. "Aux"  

will dsplay.

1.  Press A/C button to select A/C.
2. Press 

 to adjust thermostat setting below room tem-

perature. The blower should come on immediately on high 
speed, followed by cold air circulation. The display should 
show “A/C”. If the setpoint temperature display is fl ashing, 
the compressor lockout feature is operating  (see Confi gu-
ration menu, item 7).

3.  Adjust temperature setting to 3° below room temperature.

The second stage cooling should begin to operate. A click 
from the thermostat will be heard to confi rm second stage.

4. Press 

 to adjust the temperature setting above room

temperature. The cooling system should stop operating. 

When the thermostat is confi gured for Heat Pump mode and 
the Dual Fuel feature is selected, the thermostat can use 
software logic to determine when to switch to gas heat and 
shut down the compressor. This eliminates the need for a 
fossil fuel kit. 

The user selectable temperature is called the dual fuel tem-
perature setpoint (dF) and is set in the Installer/Confi guration 
menu, item 20. A software logic based dual fuel number from 
1 to 9 can be selected. A selection of 5 is recommended. A 
higher number will provide a larger stage separation. A lower 
number will provide a smaller separation.

After the dual fuel temperature setting is selected, press 
Menu. A compressor delay (Cd) can be set for compressor 
shutdown after the auxiliary stage is energized. This delay 
will minimize the time the system may blow cooler air until the 
alternate source of heat comes on. Default setting for delay is 
60 seconds. This delay can be set from 0 to 99 seconds using 
the 

 or 

 buttons.

Compressor Delay (Cd) will not be available if dF is selected 
0 (off).
