SECTION 7
Setting the Humidistat
This fan is equipped with a humidity sensor that automatically turns the fan on when humidity
is above set point and off when humidity is at or below set point. If the fan is operating too
long or not enough, first check to see the humidity sensor set point. In cases where the
ambient humidity level of the room rises higher than the preset level, the fan will turn on even
if the room is not occupied. This helps prevent conditions that lead to mold growth.
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE
SERVICING THE UNIT.
1.
To set the desired humidity level of the room, remove the grill and locate the
dehumidistat dial located on the wire compartment cover.
2.
Set the dial to the relative humidity you want the fan to maintain usually between 50 &
80%. Moist climates will require higher settings than dry climates. When the humidity
level of the room is below this setting the fan will remain off. When the humidity level
rises about this setting the fan will turn on and run until the humidity level falls below
this setting.
3. Reinstall the grill and restore power.
