Fan Cycle Switch
This switch is set at
at
the factory to provide continuous
fan operation in cool or heat
modes. Leaving the switch in the
setting allows continuous
circulation of room air and
will result in a more balanced

If you want the fan to cycle on
and off with the compressor or
resistance heater, set the switch
at CYCLE.
Unit Power Switch
This switch controls power to the
cool, heat or fan modes. When set
at ON it allows the unit to operate
in the cool, heat or fan modes.
If this switch is set at OFF, the
unit will not operate in any modes
but the Freeze Sentinel will
still function.

behind the room cabinet. These
terminals may also be used an
interface for other systems used to
control the unit such as infrared
detectors, key-activated systems,
etc. The Freeze Sentinel remains in
an active mode to
protect
against low temperature damage
even though the unit may be OFF
at the central control location.
