ELECTRONICS OPERATION ALGORITHM
The fan with the T timer activates upon control voltage application to the Sinput terminal by the S1 external switch (e.g.
indoor light switch). After the control voltage is off, the fan continues to operate within the time set by the timer ranging
from 2 to 30 minutes. For the ST model, the fan is turned on/off with an internal cord switch.
A fan with a TR timer – when the control voltage is applied to the Sinput by an external switch S1 (for example, switching
on the room light), the turn-on delay timer is activated, and the fan blades do not rotate. The value of the turn-on delay time
is adjustable in the range from 0 to 2 minutes. Select the adjustment range using the jumper on the timer board.
After some turn-on delay time has elapsed, the fan turns on and the blades start rotating. After the control voltage is off, the
fan continues to operate within the time set by the turn-off delay timer adjustable from 2 to 30 minutes.
The two-speed fan with a V2 TR timer operates at Speed 1 when the control voltage is applied to the Sinput with the S1
external switch. The turn-on delay timer turns on, and the fan blades do not rotate. The value of the turn-on delay time is
adjustable in the range from 0 to 2 minutes. After some turn-on delay time has elapsed, the fan switches to Speed 2.
After disconnecting the control voltage, the fan runs for a time set by the turn-off delay timer (from 2 to 30 minutes), and
switches to the first speed.
The fan with the timer and the humidity sensor H – 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 turn-
off delay timer ranging from 2 to 30 minutes.
The double-speed fan with a timer and a humidity sensor V2 Н switches to Speed 2 as the indoor humidity exceeds set
level (adjustable from 60 % up to 90 % ). As the indoor humidity level drops down to the set value, the fan keeps operating
for 5 minutes and then switches to Speed 1. The fan can be controlled manually, for example, with a light switch.
When the control voltage is applied, the turn-on delay timer is activated for 45 seconds and the fan switches to the second
speed. After disconnecting the control voltage, the fan runs for a time set by the turn-off delay timer (from 2 to 30 minutes),
and switches to the first speed. To set the maximum humidity setpoint, set the potentiometer to Hmax position (90 %).

— To adjust the fan turn-on delay time, turn the control knob Ton clockwise to increase and counter-clockwise to
decrease the turn-on delay time respectively, adjustable from 0 up to 2 minutes.
— To adjust the fan turn-off delay time, turn the control knob To clockwise to increase and counter-clockwise to
decrease the turn-off delay time respectively, adjustable from 2 up to 30 minutes.
— To adjust the humidity set point, turn the control knob Hclockwise to increase and counter-clockwise to decrease the
humidity sensor set point, adjustable from 60 % up to 90 %.
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.
