Description

APPLICATIONS
Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.	For mounting in windows.
DESIGN
Modern design and aesthetic look. The casing and the impeller are made of high-quality durable ABS plastic, UV resistant. The intellectual impeller design makes the fan efficiency high and the service life long. The fan and motor are specially designed for silent operation.	Fan is equipped with a backdraft damper for back flow preventing. The fan is equipped with an external hood. Protection rating IP 24.
MOTOR
Reliable and low-watt electric motor. Designed for continuous operation and requires no maintenance.	Equipped with overheating protection.
CONTROL
Manual: The fan is controlled by a room light switch. It is not included in the delivery package. The fan is controlled by the built-in pull cord switch V. 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 the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately. By the timer T (the built-in run-out timer enables the fan operation within 2 to 30 minutes after the fan switching off).
MOUNTING FEATURES
The fan is mounted directly into the window opening.	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.
