Description

APPLICATIONS
Continuous or periodic air extraction of bathroom, showers, kitchens and other utility spaces. Ventilation shaft mounting or duct connection.				Delivery of low and medium intensity air flow to small distances over a low-resistance ventilation system. Compatible with 100, 125 and 150 mm ducting.
DESIGN
Combine modern design and esthetically pleasing appearance. The body and impeller are made of high-quality durable ABS plastic, UV resistant.				The impeller design contributes to an improved fan performance and prolonged motor service life. Protection Class IP 24.

MOTOR
Reliable and energy-efficient electric motor. Intended for continuous operation and maintenance-free.				Equipped with integral overheating protection.
Manual: The fan is controlled by means of the room light switch. The switch is not included in the delivery package. Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may connected to the same controller. Speed controllers can not be connected to the fans with T, TH, TP, VT, VTH modification.				Automatic: By means of electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.
MOUNTING
The fan is mounted directly into the ventilation shaft opening. If the ventilation shaft remoteness prevents direct installation flexible ducts may be used. The ducts are coupled with the fan outlet flange by means of a clamp.				Fixed to the wall on self-tapping screws. For 12 V low-voltage motor fan connection to 220 V / 50 Hz power mains use the step-down transformer TRF 220/12-25 that is available upon separate order.

Operating logic of the fans with optional equipment

The fan equipped with a timer is activated by the control voltage supplied to LT input. After the control voltage is disconnected the fan continues operating within the time period within 2 to 30 minutes according to the timer settings. The turn-off delay time is adjusted by turning the respective potentiometer T control knob clockwise to increase and counter-clockwise to reduce it.
The fan equipped with a timer and humidity sensor is activated by the control voltage supplied to LT input or in case of exceeding the preset humidity threshold value adjustable from ~60% to ~90%. After the control voltage is disconnected or as the humidity level H drops below the set threshold the fan continues operating within the time period within 2 to 30 minutes according to the timer settings. The turn-off delay time and the threshold humidity level are adjusted by turning the control knob of the respective potentiometer T for timer and H for humidity sensor clockwise to increase and counter-clockwise to reduce the set value. To set the maximum humidity level (90%) set the potentiometer control knob for H max position.
The fan equipped with a timer and motion sensor is activated in case of the moving detection at the distance from 1 m to 4 m with 100° detection angle. After motion is off the fan continues operating within the time period within 2 to 30 minutes according to the timer settings. The turn-off delay time is adjusted by turning the respective potentiometer T control knob clockwise to increase and counter-clockwise to reduce it.
Wiring diagram for connection of the light lamp to the fan timer operated by the common switch is shown on diagram 4. Upon the light lamp disconnection the fan continues operating according to the timer setting within the set time period.
