OVERVIEW

The Aprilaire® Dehumidifier is designed to control humidity inside the whole home.. The dehumidifier uses a dew point calculation to control the humidity based on the dryness set point on the dehumidifier control.. An optional Model 70 Living Space Control or third-party control can be used in place of the onboard control..

The dehumidifier has a built in feature to allow air cycling or ventilation.. Air cycling allows activation of the HVAC fan to cycle air throughout the home for airflow balance and comfort.. Ventilation brings fresh air into the home and is designed to meet ASHRAE 62..2 Standard for Ventilation..

There are three main installation options, Whole-Home, Spot, and Convertible..
