includes a specially designed plastic screwdriver for fan settings
adjustments.
Use the screwdriver to change the turn-off delay time or the humidity set
point, see step 4.7.
ATTENTION! The fan rated for 12 V power mains (marked on the fan casing) connect to 12 V power mains only!
ELECTRONICS OPERATING LOGIC
The fan with the timer T – the fan starts after the external switch, e.g. the light switch, supplies control voltage to the input terminal LT (ST). After the control voltage is off, the fan continues operating within the set time period adjustable from 2 to 30 minutes by the timer. The VT model is turned on and off by the pull-cord switch.
The fan with the timer T1 – the turn-on delay timer is activated after
the external switch, e.g. the light switch, supplies control voltage to the
input terminal LT (ST). The fan starts only after the turn-on delay timer
countdown. The turn-on delay time is adjusted in two ranges from 10 seconds to
90 seconds and from 2 minutes to 30 minutes. After the control voltage is off,
the fan operates within the time period set with the timer from 2 to 30
minutes. The adjustment range is selected with a jumper on the timer circuit
board.
The fan with the timer and the humidity sensor TH – the fan starts after the
external switch, e.g. the light switch, supplies control voltage to the input
terminal LT (ST) or if indoor humidity level H exceeds the set point
adjustable from 60% to 90%. After the control voltage is off, the fan operates
within the time period set with the timer from 2 to 30 minutes. To set the
maximum humidity set point turn the potentiometer control knob to H max (90%)
position.
To adjust the turn-on delay time turn the control knob of potentiometer T
clockwise to increase the set point and counterclockwise to decrease it.
To adjust the humidity set point turn the control knob of H potentiometer
clockwise to increase the humidity sensor threshold and counterclockwise to
decrease it.
Warning! The timer circuit is under mains voltage. Disconnect the fan from power mains prior to any adjustment operations. The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments. Use the screwdriver to change the turn-off delay time or the humidity set point, see step 4.7. Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
