Operating Your Thermostat

Check Thermostat Operation

NOTE

To prevent static discharge problems, touch side of thermostat to release static build-up before touching any keys.

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

Fan Operation

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.

!CAUTION

Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.

Heating System

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 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 7).

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 will show "Aux" and "Heat".

4.Press to adjust the thermostat below room tempera- ture. The heating system should stop operating.

Auxiliary (Emergency) System

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.

!CAUTION

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.

Cooling System

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 ﬂashing, the compressor lockout feature is operating (see Conﬁgu- 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 conﬁrm second stage.

4.Press to adjust the temperature setting above room temperature. The cooling system should stop operating.

Dual Fuel Temperature Setpoint and

Compressor Delay

When the thermostat is conﬁgured 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/Conﬁguration 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).
