starts operation either as control voltage is supplied to LT input
terminal or as indoor humidity level exceeds the pre-set value
regulated between 60% and 90%.
As control voltage is off or as indoor humidity level drops below
the pre-set level the fan continues operating within the time
period set by the regulated timer from 2 to 30 minutes.
