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 air ow.
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 in uence the precision of the humidity detector.
Readjusting the humidity switch will address this issue.
Factory setting: low speed air ow 40CFM, humidity 60%RH.
