SYSTEM OPERATION
•
The compressor and condenser fan are energized. The
compressor is connected to the Y terminal of the con-
trol module.
•
The circulator fan is energized at cool speed after a
cool on delay. The electronic air cleaner will also be
energized.
•
After the thermostat is satisfied, the compressor is
de-energized and the Cool Mode FanOff Delay period
begins.
•
Following the 60 second Cool Mode Fan Off Delay
period, the cool circulator and air cleaner relay are
de-energized

ON:
•
On a call for Fan, the G thermostat contacts close
signaling the control module.
•
The LED will display a solid “GREEN”
•
When a call for G is received, the control will energize
the circulator in low heat speed after the fan on delay
time expires. The electronic air cleaner will also be
energized at this time.
•
When the thermostat fan switch is moved to the ON
position, the circulator blower is energized at low heat
speed and the electronic air cleaner is also energized
•
When the thermostat fan switch is moved back to the
AUTO position, the circulator fan and air cleaner relay
are de-energized and the control awaits a thermostat
call for heat or cool.
•
Exception: During the Cool “On”delay, the control will
not respond to the fan input. If the fan was called prior
to the call for cool, the circulator will remain ener-
gized during the Cool “On”delay.
•
If the fan is called prior to a call for heat, the circulator
will remain energized during the entire call for heat
sequence.
