This Exhaust Control allows the air conditioner to either circulate inside air (Closed) or exhaust
air to the outside (Open).
The Closed position is used when maximum cooling is desired. It may also be used for air recirculation without cooling when the air conditioner is set in any FAN position.
The Open position removes stale air from the room and exhausts it to the outside. Fresh air is
drawn in through normal passages in the home.
