connected or from the time of humidity drop set on the humidity sensor potentiometer�
ATTENTION: When the green diode located in the electronic system is on, it means that the humidity
level in the room is higher than the preset on the potentiometer controlling the humidity level
adjustment. As long as the diode is on, the fan will not start counting down the stop delay after
which the fan is switched off. It will take place only after the humidity level in the room drops and
the green diode goes off.
