Switch E controls the Freeze
Sentinel. When the switch is
DOWN
the Freeze Sentinel automatically
turns on the resistance heater and
fan if the room temperature (sensed
at the unit) drops to approximately
40
° F. It will turn the heater off when
the temperature reaches about 45° F.
The unit leaves the factory with the
Freeze Sentinel in the
DOWN
(on)
position.
The Freeze Sentinel helps prevent
plumbing damage in the room due
to sub-freezing temperatures.
If the Freeze Sentinel is set, it is
active as long as power to the
unit is on.
NOTE: The owner is responsible for
checking the Freeze Sentinel switch
and ensuring it is in the desired
setting.

The fan switch #9 is located behind
the room cabinet.
This switch is set at continuous fan
(
DOWN
) at the factory to provide
continuous fan operation in cool
or heat modes. Leaving the switch
in the continuous fan setting allows
continuous circulation of room air
and will result in a more balanced
temperature throughout the room.
If you want the fan to cycle on
and off with the compressor or
with the heater, move the switch
to cycle fan (
UP
).
