CHECK THERMOSTAT OPERATION
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.
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.
CAUTION
!
Topreventcompressorand/orpropertydamage, ifthe
outdoor temperature is below 50°F, DO NOT operate
the cooling system.
3. Move FAN switch to AUTO position. The blower should stop
immediately.
Heating System
1. Move SYSTEM switch to COOL position.
1. Move SYSTEM switch to HEAT position. If the heating
system has a standing pilot, be sure to light it.
