MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.
ELECTRONIC SYSTEM OPERATION ALGORITHM
The T model fans
equipped with a timer are activated by control voltage application to input terminal
S
by an external
switch (e.g. indoor light switch). Upon control voltage removal the fan continues to operate for the period of time set by the
timer within the range from 2 to 30 minutes.
Fan with a ТR timer
. When control voltage is applied to input terminal
S
by the external switch (e.g. indoor light switch), the
turn-on delay timer is activated. The fan blades do not rotate. The turn-on delay time is in the range from 0 to 2 minutes. The
adjustment range can be selected by means of the potentiometer on the timer circuit board. Upon control voltage removal
the fan continues to operate for the period of time set by the turn-off delay timer within the range from 2 to 30 minutes.
The fan with the V2 ТR
timer runs at Speed 1. When the control voltage is applied to the S input, the turn-on delay timer
is activated by the external switch from 0 to 2 minutes, and the fan switches to 2nd speed. You can select the control range
using a potentiometer on the timer board. After removing the control voltage, the fan continues to operate for the time
specified by the turn-off delay timer, which ranges from 2 to 30 minutes, then switches to Speed 1.
The H model fans equipped with a timer and a humidity sensor
are activated by control voltage application to input
terminal
S
or on exceeding the pre-set humidity level
H
adjustable within the ~60 % to ~90 % range. Upon control voltage
removal or a decrease of humidity level
H
the fan continues to operate for the period of time set by the timer within the
range from 2 to 30 minutes.
A V
2 Н double-speed fan with a timer and humidity sensor
is switched to the Speed 2 when the set humidity level
in the room (from 60 to 90 %) is exceeded. As the indoor humidity level drops down to the set value, the fan continues to
operate for 5 minutes and goes to the Speed 1. The fan can be turned on in manual mode, for example, using a light switch.
After turning on the switch, the fan switches to Speed 2 with a time delay of 45 s. After the switch is turned off, the fan will
continue to work at the Speed 2 for the time set by the turn-off delay timer, from 2 to 30 minutes, then it will switch to the
Speed 1.To set the maximum level of humidity, it is necessary to set the potentiometer regulator to the
H
max position
(90 %).
