Vent Control
NOTE:
Vent control is only used on units with the power
vent or power vent door kit not installed.
The vent control allows fresh air to be drawn into the condi-
tioned area. This fresh air can provide ventilation when the
blower is operating, but it will increase the heating or cool-
ing load and operating costs.
