NOTE:
If the housing is mounted too far or not far enough into the ceiling for the flange to
make a solid connection, loosen the mounting channel and adjust the housing up or down on
the rails. Once in place, fully tighten the mounting channel nuts.
5a.
STANDARD AND HUMIDITY SENSING MODELS:
Install the grill by squeezing the two
ends of the springs together and installing them up into the slots on the fan’s housing.
Push the grill up into position
(Figure 12).
5b.
MOTION SENSING MODELS:
Install the grill by squeezing the spring furthest from
the motion sensor together and installing it up into the slot furthest from the wire
compartment on the fan’s housing. Attach the 3 pin quick connect from the motion sensor
on the grill to the wire compartment
.
This cord will only fit one way into the receptacle.
Install the other spring in place and push the grill up into position
(Figure 13).
6.
Restore power and test your installation.
SECTION 7
Programming the Occupancy Sensor
1a.
Setting the Occupancy Time Delay.
This will set the amount
of time the fan will continue to operate after the room is
vacated. Locate the motion sensor on the fan’s grill and press
the button 2 times. The LED on the sensor will then flash the
number of times to indicate the current setting, this will repeat
3 times:
1 time = 30 seconds
2 times = 2.5 minutes 6 times = 12.5 minutes
3 times = 5 minutes 7 times = 15 minutes
4 times = 7.5 minutes 8 times = 17.5 minutes
5 times = 10 minutes 9 times = 20 minutes
1b. To adjust the setting, while the sensor is still flashing from
Step 1a
, press the button the
number of times that corresponds with the amount of time you desire, for instance 3 times

sets the delay to 5 minutes (see numbers in
Step 1
). The sensor will then flash the number
of times for the new setting 3 times before exiting back to the programming mode.
2a
Setting the Minimum On Time.
This sets the minimum time the fan will operate once
motion is detected within the room. This works in conjunction with the Occupancy Time
Delay feature set in
Steps 1a
and
1b
. For instance if you set the minimum time on for 15
minutes and the Time Delay for 5 minutes, the fan will operate for at least 15 minutes
then 5 additional minutes.
NOTE:
This is a minimum time that the fan will operate. If the room is occupied longer, the
fan will continue to run until the room is vacated and the occupancy time delay has elapsed.
2b. Locate the motion sensor on the fan’s grill and press the button 10 times. The LED on
the sensor will then flash the number of times to indicate the current setting, this will
repeat 3 times:
1 time = 0 minutes
4 times = 45 minutes
2 times = 15 minutes
5 times = 60 minutes
3 times = 30 minutes
2c. To adjust the setting, while the sensor is still flashing from
Step 2b
, press the button
the number of times that corresponds with the amount of time you desire, for instance
3 times sets the minimum on time to 30 minutes (see numbers in
Step 2b
). The sensor
will then flash the number of times for the new setting 3 times before exiting back to the
programming mode.
3. Once all setting have been made and the sensor will return to detection mode and the
LED will flash when occupancy of the room is detected.
SECTION 8
Setting the Humidistat
This fan may be equipped with a humidity sensor that automatically turns the fan on when
humidity is above set point and off when humidity is at or below set point. If the fan is operating
too long or not enough, first check to see the humidity sensor set point. In cases where the
ambient humidity level of the room rises higher than the preset level, the fan will turn on even if
the room is not occupied. This helps prevent conditions that lead to mold growth.
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE SERVICING THE UNIT.
1.
To set the desired humidity level of the room, remove the grill and locate the
dehumidistat dial located on the wire compartment cover.
2.
Set the dial to the relative humidity you want the fan to maintain usually between 50% &
80%. Moist climates will require higher settings than dry climates. When the humidity level
of the room is below this setting the fan will remain off. When the humidity level rises about
this setting the fan will turn on and run until the humidity level falls below this setting.
3.
Reinstall the grill and restore power.
SECTION 9
Setting the Speed
This unit features a variable speed function that allows it to be set from 30 to 130 CFM. To
adjust the airflow:
1.
Remove the grill and find the adjustment post on the top of the wire compartment.
2.
Turn the post to the desired CFM setting then reinstall the grill.
NOTE:
The motor will adjust to the static pressure of the installation to maintain the desired
CFM. For higher speeds / higher static pressure installations, airflow testing may be required
to insure the proper amount of ventilation.
SECTION 10
Use and Care
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE SERVICING THE UNIT.
1.
Cleaning the Grill:
Remove grill and use a mild detergent, such as dishwashing liquid,
and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS.
Completely dry grill before reinstalling. Refer to instructions in
Section 6
Completing the
Installation
, to reinstall grill.
2.
Cleaning the Fan Assembly:
Wipe all parts with a dry cloth or gently vacuum the fan.
NEVER IMMERSE ELECTRICAL PARTS IN WATER.
Fuse
1.
Follow the steps in
SECTION 5
Wiring
to gain access to the
fuse holder located inside the wire compartment. To replace
the fuse, squeeze the top an bottom of the fuse holder together
while twisting the larger piece in a direction away from the
tabs
(Figure 14)
. Replace fuse only with 0.5 Amp, 250VAC, 5 x
20mm, Fast Acting fuse. Reconnect the fuse holder by lining up
the top an bottom section and squeeze together while twisting
until they are locked in place. Carefully tuck back into the wire
compartment and reinstall the wire compartment cover.
