Aprilaire Model 1700 - Manual (Page 2)

I. PRINCIPLE OF OPERATION
The Model 1700 Dehumidifier may be difficult to access in locations such as attics and crawlspaces,
and 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 Model 1700 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 Model 1700 main control board
sensors when connected and enabled.
