BRIEF DESCRIPTION
The product described herein is an axial fan for supply and exhaust ventilation of small and medium-sized remises heated during winter time. The fan is made of white plastic.
To prevent air backdrafting to the room during the fan standby, the fan series M, M1 and M3 may be equipped with a foil back valve; the fan series MA, LD Auto and Modern Auto may be equipped with automatic louvre shutters.
The fan is designed for connection to Ø 100, 125 and 150 mm air ducts.
Due to constant improvements the design of some models may slightly differ from those ones described in this manual.
OPERATION GUIDELINES
The fan is designed for connection to AC 220-240 V, 50 Hz power mains.
The model 12 is designed for connection to 12 V, 50 Hz power mains directly or to AC 220-240 V, 50 Hz ower mains through the step-down transformer, for example, TRF 220/12-25 (optional).
The fan is designed for continuous operation always connected to power mains.
Air flow direction in the system must match the pointer direction on the fan casing.
Ingress protection rating against access to hazardous parts and water ingress:
IP24 - MA series;
IP34 - M, M1, M3, LD Auto, Modern Auto series.
The fan is rated for operation at the ambient temperature ranging from +1°C up to +45°C.
The fan requires no grounding.

MOUNTING
The fan is designed for ceiling or wall surface mounting and air extraction through a ventilation shaft or round air duct of respective diameter, fig. 1.
Fan mounting sequence:
Step 1 - cut off power supply and prepare a premise for the fan installation, fig. 2-3.
Step 2 - take off the front cover from the fan, fig. 4;
Step 3 - mark and drill the holes for the fan fixation, install the fan, fig. 5-7;
Step 4 - connect the fan to power mains and adjust the timer and the humidity sensor set point if required, fig. 8-14;
Step 5 - re-install the front cover on the fan casing, fig. 15;
Step 6 - connect the fan to power mains, fig. 16.
Note: the figures show the M series fan.
Mounting, connection, adjustment and maintenance sequence of M1, M3, MA, LD Auto and Modern Auto fan series is the same.

ELECTRONICS OPERATING LOGIC
The fan with the timer T - the fan starts after the external switch, e.g. the light switch, supplies control voltage to the input terminal LT (ST, SL). After the control voltage is off, the fan continues operating within the set time period adjustable from 2 to 30 minutes by the timer.
The VT model is turned on and off by the pull-cord switch.
5
EN
The fan with the timer T1 - the turn-on delay timer is activated after the external switch, e.g. the light switch, supplies control voltage to the input terminal LT (ST). The fan starts only after the turn-on delay timer countdown. The turn-on delay time is adjusted in two ranges from 10 seconds to 90 seconds and from
2 minutes to 30 minutes. The adjustment range is selected with a jumper on the timer circuit board.
After the control voltage is off, the fan operates within the time period set with the timer from 2 to 30 minutes.
The fan with the timer and the humidity sensor TH - the fan starts after the external switch, e.g. the light switch, supplies control voltage to the input terminal LT (ST) or if indoor humidity level H exceeds the set point adjustable from 60% to 90%. After the control voltage is off, the fan operates within the time period set with the timer from 2 to 30 minutes.
To set the maximum humidity threshold rotate the potentiometer knob to H max position
1 to 4 m and the horizontal viewing angle of 100°. After no more motion is detected, the fan operates within the time period set with the timer from 2 to 30 minutes.
To adjust the fan turn-on delay time, turn the potentiometer control knob Tz clockwise to increase and counter-clockwise to decrease the turn-on delay time respectively, fig. 12.
To adjust the fan turn-off delay time, turn the potentiometercontrol knob T clockwise to increase and counter-clockwise to decrease the turn-off delay time respectively, fig. 12-13.
To adjust the humidity set point rotate the potentiometer control knob H clockwise to increase and counter-clockwise to decrease the humidity threshold accordingly, fig. 13.
Warning! The timer circuit is under mains voltage.
Disconnect the fan from power mains prior to any adjustment operations.
The fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments.
Use the screwdriver to change the turn-on and turn-off delay time or the humidity set point (fig. 14).
Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
