This
CLOSE at the
factory. When it is in this position,
the vent door is closed and only
indoor air is filtered, cooled or
heated and circulated by the air
conditioner.
Switching the knob to OPEN opens
the vent door to allow some outside
air to enter the room. However,
cooling or heating effectiveness is
reduced when the control is set at
OPEN, so we suggest you don't
keep it there long.
If the knob is not set all the way in
CLOSE position, the vent light will
remain on.

operation in cool or heat modes. If
you want the fan to cycle on and off
with the compressor or resistance
heater, set the switch at ~CLE.

For maximum heating economy,
this switch is set at MAXIMUM

temperature drops to 15°F., the heat
pump is the primary source of heat.

At 15°F. and below, full resistance
heat takes over.
Set this switch at NORMAL and
the change from heat pump to
resistance heating occurs when
the outside air temperature drops
to 35°F.
Temp Limit Switih
The TEMP LIMIT switch is used
to adjust the thermostat range. Set
it to limit the lowest temperature
that can be obtained on cooling and
the highest temperature that can k
obtained on heating.
COOL and HEAT settings range
from NORMAL to TL3. Both
controls are set at NORMAL at
the factory.
