5 CHECK THERMOSTAT OPERATION

NOTE

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

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

Fan Operation

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

1.Turn on power to the system.

2.Move FAN switch to ON position. The blower should begin to operate.

3.Move FAN switch to AUTO position. The blower should stop immediately.

Cooling System

!CAUTION

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

This thermostat has a time delay between cooling cycles to allow the head pressure in the compressor to stabilize. If the tempera- ture is adjusted to call for cool within 5 minutes of the last cycle the snowflake icon will blink indicating the thermostat is locked out. After 3 to 5 minutes, the compressor will start and the snowflake icon will stop flashing. This helps prevent the compressor from cycling too quickly and is normal operation for the thermostat.

1.Move SYSTEM switch to COOL position.

2.Press to adjust thermostat setting below room tempera- ture. The blower should come on immediately on high speed, followed by cold air circulation

3.Press to adjust temperature setting above room tem- perature. The cooling system should stop operating.

Heating System

1.Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.

2.Press to adjust thermostat setting above room tempera- ture. The heating system should begin to operate.

3.Press to adjust temperature setting below room tem- perature. The heating system should stop operating.
