the humidity control. See “Connect Wiring” for details.
SENSOR OPERATION
The humidity-sensing
fan uses a sophisticated humidity sensor
that responds to: (a) rapid to moderate increases in humidity or (b)
humidity above a set-point. The humidity sensor may occasionally
turn the fan ON when environmental conditions change.

The humidity sensing fan has an additional operation feature. For
odor or vapor control, the fan can be energized by cycling the
power switch. Once the fan has been energized in this manner, it
will remain on for 20 minutes.
To manually energize the fan:
1. If fan power switch is already ON, proceed to Step 2; otherwise,
turn power switch ON for more than 1 second.
