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 blower assembly 

(includes motor and impeller).

OPERATION

The humidity control and fan can be operated 

separately. Use a 1- or 2-function wall control. Do 

not use a dimmer switch to operate the humidity 

control.

SENSOR OPERATION

This 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.

MANUAL ON WITH TIMED OFF

This 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 the set timer period.

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.

2. Turn fan power switch OFF for less than 1 

second.

3. Turn fan power switch back ON and fan will turn 

ON.

% HUMIDITY ADJUSTMENT

%HUMIDITY has been factory set at 80% for most 

shower applications. If fan is not responding to changing 

humidity conditions, adjust toward 50%. If fan is 

responding too often to changing humidity conditions, 

adjust toward 80%. If fan is still responding too often at 

80%, contact Broan Technical Support.
To adjust the %HUMIDITY:

1. Turn power off at electrical service panel.

2. Use a small screwdriver to carefully rotate 

%HUMIDITY control to desired level.

3. Turn power on.

4. Repeat above steps if necessary.

MINUTES ADJUSTMENT (TIMER)

This humidity-sensing fan has a timer that controls how 

long the fan remains on after (a) rise in humidity and 

(b) humidity level are both below the user-adjustable 

%HUMIDITY setting, or after being energized by cycling 

power switch.

To adjust the timer:

1. Disconnect power at electrical service panel.

2. Use a small  screwdriver to carefully rotate MINUTES 

control to increase or decrease time.

3. Turn power on.

4. Repeat above steps if necessary.

Factory settings shown.

SENSOR CLEANING

The humidity sensor is mounted in the control housing. 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!
