ELECTRONICS OPERATION ALGORITHM
The fan with the timer T
— the fan is started after actuation of the external switch, e.g. the light switch. The control voltage
is supplied to the input terminal
LT (ST)
. After the control voltage is off the fan continues to operate 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
— after turning on the switch, for example, a light switch, the fan is switched on in a set turn-on
delay time period, adjustable from 0 to 2 minutes. After the switch is turned off the fan keeps operating for a set turn-off
delay time period, adjustable from 2 to 30 minutes.
The fan with the timer and the humidity sensor TH
— the fan starts after the control voltage is supplied to the input
terminal S or if indoor humidity level
H
exceeds the set point adjustable from ~60 % to ~90 %. After the control voltage is off
or the humidity level has decreased the fan will keep running within the time set by the timer ranging from 2 to 30 minutes.
To set the maximum humidity setpoint 90 % set the potentiometer to
H max
position.
To adjust the fan turn-on delay time, turn the control knob
T
clockwise to increase and counter-clockwise to decrease the
turn-on delay time respectively. To adjust the humidity set point turn the control knob
H
clockwise to increase and counter-
clockwise to decrease the humidity sensor set point.
CAUTION! The timer circuit is live! 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 it to change
the turn-on and turn-off delay time and the humidity set point.
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
