Operation

It is normal for this ventilation fan to take approximately 5 seconds

to start running after it is turned on.

Modes

(For reference, wiring diagrams are on pages 5, 10 and 11.)

Continuous ventilation:

1. Turn master wall switch on.

2. Fan operates at user-adjustable airflow rate.

Motion sensing:

1. If master wall switch is not already on, turn it on.

2. Turn sensor/control wall switch on. Some installations may not

have a separate sensor/control wall switch; where it is com-

bined with master wall switch.

3. Fan operates at certified airflow rate and sensor detects motion.

4. When no more motion is detected, fan enters time delay mode.

(See below.)

Manual-on (optional manual-on wall switch must be installed):

1. Turn master and manual-on wall switches on (sensor/control

wall switch can be on or off).

2. Fan operates at certified airflow rate.

3. When manual-on wall switch is turned off, fan enters timed-off

mode. (See below.)

Time Delay:

Fan operates at certified airflow rate until user-adjustable TIME

delay has passed, then fan reverts to user-adjustable airflow rate.

To Set the User-Adjustable Airflow Rate*

Using a small, flat-blade screwdriver, carefully rotate the CFM

adjustment until the arrow points to the desired airflow rate.

To Set the User-Adjustable Time Delay*

Using a small, flat-blade screwdriver, carefully rotate TIME

adjustment until the arrow points to the desired minutes of time

delay.

To Set the User-Adjustable Motion Light Timed-Off**

1. This adjustment should only be made if, during installation, light

was wired to motion sensor along with the fan.

2. Using a small, flat-blade screwdrive, carefully rotate the TIME**

adjustment until the arrow points to the desired minutes light

should remain on after no more motion is detected.

3. Adjust fan Time Delay* for desire time (minutes) fan operates at

certified airflow rate after Timed-off** turns off the light. The total

certified airflow rate fan on-time is the combination of the Time

Delay* and Timed-Off** time settings.

* The user-adjustable controls are located in one corner of the

Fan Housing, behind the Grille.

** Motion Light Timed-Off adjustment is located in a different

corner of Fan Housing, behind the Grille, than the Airflow Rate*

and Time Delay* adjustments.
