Check the heating system

NOTE: If compressor lockout is set to ON, the thermostat will not call for cool until after the 5 minute safety time period and will display the message A/C return < 5 min. After the 5 minutes expire the thermostat will call for cool.

3.If the system is a multi-stage cooling system, adjust the temperature setting to at least 3° below room temperature. The second stage cooling should begin to operate.

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

1.Press Heating / Cooling Mode key one or more times to select HEAT mode. If the auxiliary heating system has a standing pilot, be sure to light it.

2.Press the to adjust thermostat setting to 1° above room temperature. The heating system should begin to operate.

NOTE: If the system is configured as a heat pump and compressor lockout is set to ON, the thermostat will not call for heat until after the 5 minute safety time period. After the 5 minutes expire the thermostat will call for heat.

3.If the system is a multi-stage heating system, adjust the temperature setting to at least 3° above room temperature. If the system is configured for a multi-stage furnace (non-heat pump), the second stage of the heating should begin to operate. Within a very short period, the Back Up heat should begin to run and Back Up Heat will be displayed.

4.Press the to adjust the thermostat below room temperature. The heating system should stop operating.
