OPERATION
To Turn Fan ON
Turn the switch I (according to the following "CONNECT ELECTRICAL WIRING" ) ON.
• Fan will run at the certified airflow rate if the switch II is ON.
• Fan will run at the user-adjustable airflow rate if the switch II is OFF.
To Use Fan Time Delay Airflow Rate Change
1. Turn the switch I ON.
2. Turn the switch II ON - fan will run at the certified airflow rate.
3. When the switch II is turned OFF, fan will continue to run at the certified airflow rate until the time delay has elapsed (for SL100-3, the delay time is
user-adjustable from 3-30mins; for SL100-3H and SL100-3HM, the delay time is 20 mins), and then will automatically change to the user-adjustable
airflow rate.
To Turn Fan OFF
Turn the switch I OFF
For SL100-3H and SL100-3HM
The fan will run continuously at a low speed (adjustable by low airflow knob) and automatically boost up to high speed when either of these conditions is
detected: a) Humidity above a user-adjustable setpoint (30%-80% relative humidity). b) rapid increases in humidity. After delay timer (20 minutes)
returns fan to the default low speed. Humidity sensor description accroding to "HUMIDITY SENSOR OPERATION" and "SENSITIVITY ADJUSTMENT".
HUMIDITY SENSOR OPERATION (For SL100-3H and SL100-3HM)
The humidity-sensing fan uses a sophisticated humidity sensor that responds to: (a) rapid increases in humidity or (b) humidity above a user-adjustable
set-point (30%-80% relative humidity). The fan will run continuously at a pre-set lower level (set by Low airflow knob) and automatically boost up to
certified airflow rate when environmental conditions change. If the fan continuously responds to changing environmental conditions, "H" (means
"humidity") adjustment may- be required.
SENSITIVITY ADJUSTMENT (For SL100-3H and SL100-3HM)
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 minimum, "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 maximum or minimum.
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.
MOTION SENSOR OPERATION for SL100-3HM
Plug the motion sensing grille into the fan control module and when powered on, the fan
will automatically start sensing motion.
Turn on the switch to activate sensor and continuous ventilation system. The fan will run
continuously at the pre-set low speed.
When motion is detected, the fan speed increases to high speed.
When the person exits the area, the fan remains working at high speed until the delay time
has passed (20 minutes).
After the time delay, the fan speed is reduced to the continuous ventilation rate.
Installation distance: 5 to 7 feet.
Sensing range is within the cone angle of 90°.
PLAN THE INSTALLATION
1. Do not use in a cooking area.
ASSEMBLY INSTRUCTIONS
1. Before installation, you need to know:
Screw A
Screw B
Hanger bar
When installing contractor packs, make sure to install any optional modules such
as speed controls or humidity sensors with the fan housing to ensure wiring is
completed properly. Module and grille plugs come packaged with the optional
accessory and must be installed with the fan housing.
