BRIEF DESCRIPTION
The product is an axial fan for exhaust ventilation of small and medium-sized premises heated in winter. The design of the fan
may include a back valve that prevents air from flowing into the room when the fan is off. The fan is designed for connection
to ø100 mm air ducts.
OPERATION GUIDELINES
The fan is rated for connection to 220...240 V / 50 Hz or 220...240 V / 60 Hz or 12 V / 50 Hz single-phase AC power mains,
depending on the model type. For more detailed information, see the casing sticker. Ingress protection rating against access to
hazardous parts and water ingress is IP44. The manufacturer’s recommended operating temperature range is +1 °C to + 45 °C.
The fan requires no grounding.

EN
MOUNTING
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. 12-13.

ELECTRONIC SYSTEM OPERATION ALGORITHM
The T model fans equipped with a timer are activated by control voltage application to input terminal Sby 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. The ST model fans are activated and deactivated by the internal cord switch.
In T1 model fans equipped with a timer the activation delay timer is activated upon application of control voltage to input
terminal Sby and an external switch (e.g. indoor light switch), but the fan blades remain in the stationary position. The

activation delay value can be set in two ranges: from 10 to 90 seconds and from 2 minutes to 30 minutes. The adjustment
range can be selected by means of the jumper on the timer circuit board. 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 TH model fans equipped with a timer and a humidity sensor are activated by control voltage application to input
terminal Sor on exceeding the pre-set humidity level Hadjustable within the ~60 % to ~90 % range. Upon control voltage
removal or a decrease of humidity level Hthe fan continues to operate for the period of time set by the timer within the
range from 2 to 30 minutes. To adjust the maximum humidity level set the potentiometer knob to the Н mах (90 %) position.
To adjust the fan activation delay time turn the Tz potentiometer knob clockwise (+) or counter-clockwise (-).
To adjust the fan deactivation delay time turn the Tpotentiometer knob clockwise (+) or counter-clockwise (-).
To adjust the threshold value of the humidity sensor turn the Hpotentiometer knob clockwise (+) or counter-clockwise (-).
— To adjust the fan activation delay time turn the Ton potentiometer knob clockwise (+) or counter-clockwise (-)
which sets the activation delay time within the range from 0 to 2 minutes.
— To adjust the fan deactivation delay time turn the To potentiometer knob clockwise (+) or counter-clockwise (-)
which sets the activation delay time within the range from 2 to 30 minutes.
— To adjust the humidity sensor threshold value turn the Hpotentiometer knob clockwise (+) or counter-clockwise (-)
which sets the threshold value within the range from 60 % to 90 %.
