Description
Description
APPLICATIONS  
  • Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.
  • Ventilation shaft mounting or duct connection.
  • Low to medium air flow motion for short distances at low air resistance.
  • Compatible with 100, 125 and 150 mm air ducts.
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 is equipped with a thermal actuator that provides smooth opening and closing of the automatic louvre shutters to prevent back draft.
  • 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. Not applied in case of ceiling mounting.
  • 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 TTHTPVTVTH 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).
  • By the humidity sensor and timer TH (if the humidity level in the room exceeds the sensor threshold adjustable value within 60-90% the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating with in the time period according to the timer setting, then shuts down).
  • By the motion sensor and the timer TP (in case of motion detection the fan switches automatically on and operates within the set time period from 2 to 30 minutes. The motion sensitivity area is up to 4 meters and the maximum detection angle is 100°.
MOUNTING FEATURES  
  • The fan is mounted directly into the ventilation shaft.
  • Flexible duct application is recommended in case of remote location of the ventilation shaft. The air duct is connected to the fan exhaust flange through a clamp.
  • Fixed to the wall by self-tapping screws.
  • Suitable for ceiling mounting.
  • Flange of 92 mm length for easy mounting into concrete walls and floor decks up to 100 mm thick.
  • 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.
