HUMIDITY SENSOR OPERATION
The humidity-sensing fan uses a sophisticated humidity sensor that responds to:
(a) rapid to moderate (user-adjustable) increases in humidity or (b) humidity above a
user-adjustable set-point (50%-100% relative humidity).
If the fan continuously responds
to changing environmental
conditions,“H” (means “humidity”) adjustment may be
required.
This feature is factory-set for about 75% (Ambient temperature of 77F).
SENSITIVITY ADJUSTMENT
The “H” has been factory set for most shower applications.
However, if the fan is in a tub area or is being used for dampness
control, the “H” may need to be increased toward maximum “+”.
If the control is responding too often to changing
environmental conditions, movement toward less “-” “H” may be required.
To adjust the “H”:
1. Disconnect power at service entrance.
2. Through the grille, locate the slot marked “H”.
3. Carefully rotate the “H” adjustment toward “+” or “-”.
4. Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.
5. Repeat above steps if necessary.
When the temperature changes, humidity sensor values will have deviation.
