Heating Control
NOTE: Heat pump models only. Heat pump equipped models use
backup electric resistance heating coils. At extremely low outdoor
ambient temperatures, the heat pump is automatically disabled and the
unit operates solely on electric resistance heat.
The heating control islocated behind the front panel at the control box
bottom and is accessible through the return air louver opening. Its
function is to allow you to set the temperature range in which the heat
pump operates. This control switches the unit heat operation between
heat pump and electric resistance heat based on the outdoor ambient
temperature. These change over temperatures are based on the
settings of this control. In most cases, the factory setting (at approxi-
mately the one o'clock position) is adequate. If you wish to change the

point.
In the event of a compressor malfunction, turn the screw to the extreme counterclockwise emergency heat position. The
heater will then cycle using electric resistance heat only. Note that in the emergency heat position, the compressor is locked
out, disabling both heat pump and cooling operations. CALL A SERVICE PERSON.

The fan cycle switch islocated behind the front panel at the bottom of the
control box. It is accessible through the return air louver opening. It is
designed to operate the fan either continuously or intermittently with the
compressor or heating elements. When the switch is in the CONTINU-
OUS position, the fan will run continuously when the power switch is on.
With the fan cycle switch in the CYCLE position, the fan will run only when
the compressor or heating elements cycle on.
I NOTE: For maximum comfort and temperature control, it is

recommended that this switch be set in the continuous position.

The vent control lever is located behind the front panel at the bottom of the
control box. When the lever is up, (OPEN), outside air is mixed with indoor
air. When the lever is down, (CLOSED), no outside air is admitted into
room and room air is recycled through unit.
I NOTE: For peak operating efficiency the vent should remain closed. I
