5-1. Single speed control mode: Turn the POWER switch on to
operate at single speed mode - the LED indicator will be
green.
Humidity Models: SIG110HL
5-2. Humidity control mode: Turn the POWER switch on to
operate at humidity control mode - the LED indicator will
be blue. When the ambient humidity is higher than the
user-adjustable set-point, the fan will run at full speed.
When the ambient humidity is lower than the set-point,
the fan will continue to run at full speed until a 10- minute
time delay has elapsed, and then will automatically
change to the user-adjustable low speed airflow.
5-3. Full speed mode: Turn the MODE switch on to operate at
full speed mode - the LED indicator will be amber.
5-4. Humidity tolerance is about ±10%. As the fan is used
throughout the years, dust will accumulate periodically.
This will influence the precision of the humidity detector.
Readjusting the humidity switch will address this issue.
Factory setting: low speed airflow 40CFM, humidity 60%RH.
