CHECK THERMOSTAT OPERATION
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.
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 tempera-
ture. 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 compres-
sor shuts down and the operator changes the setpoint
within the 5-minute time period. During this 5-minute
period, the word COOL will flash, 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.
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 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.
Before you begin programming your thermostat, you should be
familiar with its features and with the display and the location and
operation of the thermostat buttons. Your thermostat consists of
two parts: the thermostat cover and the base. To remove the
cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.
