OPERATION

The humidity control and fan can be oper-ated separately. Use a 1- or 2-func- tion wall control. Do not use a dimmer switch to operate the humidity control or light. See “Connect Wiring” for details.

SENSOR OPERATION

This humidity-sensing fan responds to:

(a)rapid to moderate humidity increases and (b) humidity above a 50%-100% rela- tive humidity set-point. (a) and (b) are set with “SENSITIVITY” adjustment. Fan may occasionally turn on when environ-mental conditions change. If the fan contin-uously responds to changing environ-mental condi- tions, “SENSITIVITY” adjust-ment may be required (see section below).

STATUS INDICATOR

This indicator can only be seen by looking directly at it. Normal mode is 5-seconds on and off. If it blinks rapidly for 5-seconds and then off, check sensor connections on grille and fan housing.

MANUAL ON WITH TIMED OFF

For odor or vapor control, the fan can be en- ergized by cycling its wall-mounted switch if one is installed. Once the fan has been turned on in this manner, it will remain on for the set “TIMER” period.

To manually energize the fan:

1.Go to Step 2 if switch is already on; otherwise, turn switch on for more than 1 second.

2.Switch off for less than 1 second.

3.Switch back on and fan will turn on.

SENSITIVITY ADJUSTMENT

“SENSITIVITY” has been factory set for most shower applications. If the fan is in a tub area or is used for dampness control, the “SENSITIVITY” may need to be in- creased toward maximum (“MAX.”). If the control is responding too often to changing environmental conditions, adjustment to- ward less (“MIN.”) “SENSITIVITY” may be required. To adjust the “SENSITIVITY”:

1.Turn power off at electrical service panel.

2.Through the grille, locate the “SENSITIVITY” screwdriver slot.

3.Using a small, flat-blade screwdriver, carefully rotate “SENSITIVITY” adjust- ment toward “MAX.” or “MIN.”

4.Turn power on and check operation by turning on shower or other humidity source until fan turns on.

5.Repeat above steps if necessary.

TIMER ADJUSTMENT

This humidity-sensing fan has a “TIMER”. It is user-adjustable from 5 to 60 minutes and is factory-set at 20 minutes. The “TIMER” controls how long the fan remains on (a) after rise in humidity and (b) humidity level are both below the user-adjustable “SEN- SITIVITY” setting or after being energized by cycling power switch.

To adjust the “TIMER”:

1.Disconnect power at electrical service panel.

2.Through the grille, locate the “TIMER” screwdriver slot.

3.Using a small, flat-blade screwdriver, carefully rotate “TIMER” adjustment to desired setting (5 to 60 minutes).

4.Check operation by cycling power switch as instructed under “MANUAL ON WITH TIMED OFF” or by turning on a humidity source until fan turns on.

5.Check “TIMER” setting with watch or clock after turning humidity source off if it was turned on it Step 4.

6.Repeat above steps if necessary.

CLEANING & MAINTENANCE

For quiet and efficient operation, long life, and attractive appearance - lower or remove grille and vacuum interior of unit with the dusting brush attachment.

The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the motor with the exact service motor. The impeller should also be replaced.

SENSOR CLEANING

The humidity sensor is mounted in the grille. The sensor will operate most reliably when cleaned occasionally as follows:

1.Disconnect power at service entrance.

2.Remove the grille. Use a dry dustcloth, clean toothbrush, or lightly vacuum to clean sensor and grille. DO NOT USE ABRASIVE CLOTH, STEEL WOOL PADS, OR SCOURING POWDERS.

3.DO NOT USE cleaning sprays, solvents, or water on or near the sensor!
