properly, contact a qualified serviceperson.
Fan Operation

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.
Cooling System
This thermostat has a built-in short-term (5-minute) time delay.
This feature is activated after the compressor shuts down and
the setpoint is changed within the 5-minute period. During this
5-minute period, COOL will flash on the display indicating that
the thermostat has locked out the compressor to allow head
pressure to stabilize. This thermostat does not sense AC power
loss and therefore does not activate the short term compressor
protection feature when power is restored.
CAUTION
!
To prevent compressor and/or property damage, if the
outdoor temperature is below 50 F, DO NOT operate
the cooling system.
1. Press SYSTEM button until COOL is displayed.
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.
