AUTOMATIC CONTROL:
• Humidity control automatically turns fan ON when either of
these conditions is detected:
- a rapid to moderate (user adjustable) increase of humidity
- humidity above user-adjustable set-point (50%-100% RH)
• Two wire manual operation for odor control - Turns fan ON
when power line through wall switch is cycled ON, OFF and
back ON
• Remains ON for a user-adjustable 5 to 60 minutes after
humidity has stabilized and is below set-point or after
manually initiated through power line cycling
• Saves energy because unit runs only for the time required. A
unit controlled with a wall timer may keep fan ON longer than
required or turn it OFF before room is sufficiently ventilated
