ExTERNAL CONTROL OPTIONS
Your Aprilaire dehumidifier can be controlled with an optional external control that is conveniently located in the living space. The Aprilaire
Model 76, 8620, and 8910 are recommended controls. The Model 76 is a dedicated dehumidifier control and the 8620 and 8910 integrate
dehumidification control as part of the thermostat minimizing the number of controls on the wall.
The Model 76 can also act as a remote control if the dehumidifier is located in a crawl space. Install the Model 76 in your living space and make
changes to the dehumidifier setting or find out what the humidity level is in the crawl space from the comfort and convenience of the living space.
If one of these controls or any other external control is installed, please refer to their owner's manuals for operating instructions. Aprilaire owner's
manuals are available at www.aprilaire.com.
If you are interested in having an external control installed, please consult your installing contractor.
Model 76 Control
*Model 8910 is designed to accommodate installation wiring issues.
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.

If you need to change the amount of time to operate ventilation, press the MODE button twice to
display the ventilation time setting. Use the UP or DOWN button to adjust the number of minutes
per hour (0–60, set to zero to turn it off) that ventilation is to run. The control will return to the
dehumidifier setting display automatically.
