These low voltage controllers are capable of operating
both the roof top air conditioner and any furnace with a
12 VDC control circuit of 1 amp or less (continuous
current).
All air conditioning equipment is subject to freeze up
when evaporator air flow is sufficiently reduced. Ducting
of any length creates potential for reduced evaporator air
flow and system freeze up. To protect both the installer
and Airxcel, Inc. from conditions that promote reduced
air flow and system freeze up, Airxcel, Inc. has equipped
the ceiling plenum compressor control circuit with a low
temperature probe. The low temperature probe monitors
the temperature of the air conditioner evaporator coil.
When the temperature of the evaporator coil drops below
28 degrees F, the switch will open, stopping compressor
operation. Compressor operation will resume once the
evaporator warms to 55 degrees F.
IMPORTANT
The low temperature sensor is part of the ceiling
plenum electrical circuit. The probe must be inserted
into the evaporator coil of the roof top unit by the
installer when bolting the ceiling plenum to the roof
top unit.
