The fan with the time switch and humidity sensor TH - the fan starts after the external switch, e.g. light switch,
has been actuated. The signal from the switch applies the control voltage to the input terminal LT (ST). The fan
also starts when the room humidity is above the switch-on humidity, adjustable from 60% to 90%. After
disconnecting the control voltage or after reducing the humidity, the fan continues to operate for the set
time, from 2 to 30 minutes.
To recruitment of maximum humidity Setpoint turn the potentiometer knob up to the H max position (90%).
To adjust the run-on time, turn the rotary knob of the potentiometer T clockwise to increase and
counterclockwise to reduce the run-on time accordingly, Fig. 12. To adjust the humidity setpoint, turn the
potentiometer rotary knob H clockwise to enlarge and counterclockwise corresponding to the reduction of
the moisture threshold, Fig. 1 2 .
Warning! The circuit board of the timer is under mains voltage! Before any setting work, disconnect the fan from the
power supply! A plastic screwdriver for changing the settings is included with the fan. Use the plastic screwdriver to set
the switch-on delay time, follow-up time and the humidity setpoint, Fig. 14.
Do not use a metal screwdriver, knife, etc. to avoid damaging the electronic board.
