VENT
OPEN
Ventilation Control
This knob is set at 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
the CLOSE position, the vent light
will remain on.
