Controls - Ultra-Aire 70H Installation Instructions Manual

A control can be used with the Ultra-Aire 70H. The Ultra-Aire 70H features a built-in dehumidistat control as well
as the ability to wire a remote mounted control to the unit. If the Ultra-Aire 70H is located outside of the area
where humidity control is desired, consider using a remote wired humidity controller that is located in the area
where humidity control is desired. If using the built-in dehumidistat to control the unit, locate the control in an
area where it can accurately sense the humidity of the area where humidity control is desired.
If the Ultra-Aire 70H is located in the area where humidity control is desired, consider using the built-in control.
Adjust the humidity control so that the unit maintains the desired level of humidity.
CAUTION!
WHEN USING A REMOTE WIRED DEHUMIDISTAT, BE SURE THE BUILT-IN DEHUMIDISTAT IS SET
TO THE OFF POSITION BY TURNING IT COUNTERCLOKWISE UNTIL IT STOPS. FAILURE TO DO
SO MAY CAUSE THE UNIT TO SENSE THE HUMIDITY FROM THE WRONG AREA.
Ultra-Aire offers the DEH 3000 proprietary control. The DEH 3000 allows homeowners to monitor and control
relative humidity and proper ventilation levels in their home. This control is also available with a remote
sensing option.
Note: The DEH 3000 is sold seperately and can be purchased online or through your local dealer. Other
thermostats are compatible with the Ultra-Aire 70H.
