NOTE

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

Fan Operation

1.Turn on power to the system.

2.Move SYSTEM switch to OFF position.

3.Move FAN switch to ON. The blower should begin to operate.

4.Move FAN switch to AUTO position. The blower should stop within a short period of time.

2.Press to adjust thermostat setting to 90° and hold for five seconds. Both stages of the heating system should begin to operate within five seconds.

3.Press to adjust temperature setting below room tempera- ture. The auxiliary heating system will stop immediately and the first stage will stop within three to four minutes.

Cooling System

!CAUTION

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

1.Move SYSTEM switch to COOL position.

2.Press to adjust thermostat setting to 45° and hold for five seconds. The blower should come on immediately on high speed, followed by cold air circulation. Both stages of the cooling system should begin to operate (if you have a two- stage cooling system).

If the fan is running but the compressor is not running and the display has CL flashing, the compressor lockout feature is operating (see Lockout Bypass Option to temporarily override the compressor lockout feature during testing).

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

LOCKOUT BYPASS OPTION

FOR QUALIFIED SERVICE TECHNICIANS’ USE ONLY. OPERATORS SHOULD NOT USE THIS FEA- TURE DUE TO POSSIBILITY OF EQUIPMENT OR PROPERTY DAMAGE, OR PERSONAL INJURY.

COMPRESSOR SHORT TERM

CYCLE PROTECTION

During normal operation, this thermostat has a built-in short term (5-minute) time delay. During this 5-minute period, the thermostat will lock out the compressor to allow head pressure to stabilize. If you want to over- ride this feature while testing thermostat operation,

simply press and buttons at the same time with the SYSTEM switch in the OFF position.

DO NOT USE THE LOCKOUT BYPASS OPTION UNLESS THE COMPRESSOR OIL HEATERS HAVE BEEN OPERATIONAL FOR 6 HOURS AND THE SYSTEM HAS NOT BEEN OPERATIONAL FOR AT LEAST 5 MINUTES.
