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 and 125 mm air ducts.
CAUTION! The decorative front panel is available separately.

OPERATION GUIDELINES

The fan is rated for connection to 220…240 V/50 Hz or 12 V/50 Hz single-phase AC power mains, depending on the model type. For more detailed information, see the casing label.
Ingress protection rating against access to hazardous parts and water ingress is IP44.
The manufacturer’s recommended operating temperature range is from +1 °C to + 40 °C.
The unit is rated as a Class II (220-240 V/50 Hz) or Class III (12 V/50 Hz) electric appliance.

DESIGNATION KEY

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. Connection diagram terminal key:

• L — line
• S1 — external switch
• N — neutral
• QF — automatic circuit breaker
• 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!
The unit with a degree of protection against access to hazardous parts and ingress of water IP44 may be installed in zones 2 and 3 according to the IEC 60364-7-701:2019.

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.
The ST model fans are activated and deactivated by the internal cord switch.
The fan with a T 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 TR timer runs at 1st speed. 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 1st speed.
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 V2 H double-speed fan with a timer and humidity sensor is switched to the 2nd speed 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 1st speed. The fan can be turned on in manual mode, for example, using a light switch. After turning on the switch, the fan switches to 2nd speed with a time delay of 45 s. After the switch is turned off, the fan will continue to work at the 2nd speed for the time set by the turn-off delay timer, from 2 to 30 minutes, then it will switch to the 1st speed. To set the maximum level of humidity, it is necessary to set the potentiometer regulator to the Hmax position (90 %).

THE TIMER CIRCUIT IS LIVE.
MAKE SURE THE FAN IS DISCONNECTED FROM POWER SUPPLY.

• 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 Toff 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 H potentiometer knob clockwise (+) or counter-clockwise (-) which sets the threshold value within the range from 60 % to 90 %. .

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD
The fan is supplied with a special plastic screwdriver.
Use the screwdriver to adjust the fan activation or deactivation delay or the humidity sensor threshold value.

MAINTENANCE
