MOUNTING AND SETUP
The fan can be mounted to the ceiling or onto a wall with air extraction into a ventilation shaft or a matching diameter
round air duct (Fig. 2). The fan installation steps are given on Fig. 3-11. Electric connection diagrams are given on Fig. 12-17.

L — line
N — neutral
S — timer control line
WARNING! Fans rated for 12 V (as specified on the fan packing and casing) must be connected to ~12 V electric
mains only!
ELECTRONIC SYSTEM OPERATION ALGORITHM
The T model fans
equipped with a timer are activated by control voltage application to input terminal
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.

The
model fans are activated and deactivated by the internal cord switch.
The fan with a T1 timer.
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 Duo T1 timer
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 1st speed.
