HOW DOES THE OPTIONAL VENTILATION WORK?
If you had your contractor install the optional ventilation feature, they calculated how much fresh air was needed based on various factors (i.e.
home size, number of occupants, local building codes, etc.). Knowing how much is needed and the rate at which fresh air will be brought into your
home, the contractor set up the dehumidifier control to operate ventilation a certain amount of time per hour to provide the needed fresh air. When
ventilation operates, a damper in a duct that brings air in from the outside opens, and your heating and cooling system blower will run to distribute
the fresh air.
