ELECTRONICS OPERATION ALGORITHM
The fan with the timer (T)
activates upon control voltage application to the
S
input 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.
The fan with the timer (TR)
– when the control voltage is applied to the
S
input 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 the timer (V2 TR)
operates at Speed 1 when the control voltage is applied to the
S
input 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 two-speed fan with the timer and the humidity sensor (V2 H)
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, by 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 set point, set the potentiometer to
H
max
position (90 %).
