PUSH-BUTTON OPERATION
Depress these buttons for the following effect:
Entirely stops system as well as closes vent (if open). If
you wish to resume cooling or heating, wait at least 3
minutes before re-starting.
Starts the air conditioning system on cooling. Cooling
will not begin if room temperature is below 60ºF (16ºC).
Starts the unit on heating.
A heat pump, unlike an electric or gas furnace, will not
supply extremely hot air from the discharge grille.
Depending on the outside temperature the air leaving
the grilles will vary. Any air temperature below 102ºF
(49ºC) will feel cool to the human body. This does not
mean the system is not working properly.

Activates indoor and outdoor motors on high speed
independently of “heat” or “cool” mode for maximum

The vent door
closes automatically when “OFF” button is depressed.
Cooling or heating is more efficient when vent is closed.
Open vent when fresh air is desired.
Closes vent door while unit is in operation.
Activates indoor and outdoor motors on low speed
independently of “heat” or “cool” mode for minimum
sound level.
TEMPERATURE LIMITING
THERMOSTAT (If Equipped)
Remove the thermostat knob and observe its plastic rib
directly under the RED indicator line. Also observe the
eight holes in the dial plate surrounding the thermostat
stem. Refer to Figure 1 showing letters “A” through “H”
identifying these holes for future reference.
There
should be two screws located in holes “A” and “H”. The
approximate temperature range (with screws in these
positions) is 64º to 89ºF (18º to 32ºC).
Each hole
represents approximately 3 1/2º F (2ºC) change from
adjacent hole.
In Order to set the temperature range, move screws to
desired location.
Replace thermostat knob so the RED indicator line is
between the two screws.
EXAMPLE: It is desired to limit the temperature range
from 71º to 81ºF (22º to 27ºC). Relocate the two screws
in the holes “C” and “F” and replace the thermostat knob
so the RED indicator line is between the two screws.
