This Aprilaire Central Dehumidifier is designed specifically to control humidity inside the whole home as well as in crawlspaces
and attics. This dehumidifier automatically and continually measures the true measure of moisture level, dew point. The unit
operates to control humidity to the dryness set point that is either set on the unit or on the optional living space control.
A built-in, automatic air cycling feature can be utilized to activate the HVAC fan to cycle the air throughout the whole home for
proper balance for comfort. See Air Cycling, page 10, for more details on this feature.
This dehumidifier also has a patented, built-in ventilation feature, which will allow fresh air to be brought into the home from the
outside. In utilizing this feature, the dehumidifier will dehumidify the incoming air, if needed (based on dew point / dryness set
point), as the outside air is first entering the home. The built-in ventilation feature is designed to be able to meet ASHRAE 62.2
Standard for Ventilation. See Ventilation, page 10, for more details on this feature.
