An automatic configuration feature detects the
unit options installed on a unit when a spare parts
controller is installed in the unit and powered up
for the first time. After the initial unit power up,
the controller turns the Auto Configuration feature

The Auto Configuration feature detects the
following options and sets the correct value in
Configuration menu:
•
Number of Supply Air Sensors (1 or 2):
Controller detects left hand and right supply
air sensors.
•
Number of Evaporator Fans (2 or 3)
•
Dehumidify (On or OFF): If controller detects
a humidity sensor, it then checks for current
draw on a dehumidify valve.
•
Humidification (On or OFF): If controller
detects a humidity sensor, it then checks for
current draw on an air compressor.
