EXTERNAL CONTROL OPTIONS
Your central dehumidifier can be controlled with an optional external control that is conveniently
located in the living space. The Model S1-RP-76Y is the recommended control.
The Model S1-RP-76Y can also act as a remote control if the dehumidifier is located in a crawl
space. Install the Model S1-RP-76Y 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 an external control is installed, please refer to the owner’s manual that comes with the control
for operating instructions.
If you are interested in having an external control installed, please consult your installing contractor.
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.
