Living Space Control

I. PRINCIPLE OF OPERATION

It may be impractical or inconvenient to access and control your Aprilaire Central Dehumidifier under certain
circumstances. For instance, installations in attics and crawlspaces may be difficult to access. You may wish
to control the moisture level in a specific area, such as a living room or master bedroom. The Model 70
Living Space Control provides you with a convenient, accessible means of turning the Dehumidifier on and
off and allows for adjustment of the dryness level set point. The Model 70 Control contains its own sensors
that override the dehumidifier’s main control board sensors when connected and enabled.
