Mode 4 (two-speed mode) • The fan is turned off by default. The fan starts operating at the 1st speed when the switch is closed and switches to the 2nd speed when the humidity sensor is activated. Mode 5 (two-speed mode) Intellectual axial low-noise and energysaving fan for exhaust ventilation with air capacity up to 370 m3/h • The fan operates at the 1st speed by default. The fan switches to the 2nd speed when the switch is closed or the sensors are activated. Quiet VTH modification with pull-cord switch, off-delay timer with operating time from 2 to 0 3 min and humidity sensor with threshold from 60 to 90%. Quiet TP - modification with off-delay timer with operating time from 2 to 30 min and motion sensor; reach distance up to 4 m, viewing angle up to 100°. * Models VENTS 150 Quiet with modification T / TP / VT / VTH additionaly supplied with turn-on delay timer adjustable from 0 up to 2 minutes. Operation modes of the VENTS 150 Quiet and VENTS 150 Quiet Extra Operation modes of the fans models VENTS 150 Quiet and VENTS 150 Quiet Extra with modifications T, TH, VT, VTH, TP is selected by setting the DIP switch into the required position. • The fan is turned off by default. The fan starts operating at the 1st speed when the switch is closed or when the humidity sensor is activated. If during the operation at the 1st speed the second even takes place. i.e. the switch is closed or the humidity sensor is activated, the fan switches to the 2nd speed. Control Manual control: • Manual control with a room light switch. The switch is not included into delivery set. • 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 or through speed switch P21-300 (only for VENTS 150 Quiet models), 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 control: • 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 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 within the set time period and shuts down). • By the motion sensor and timer TP (if motion is detected in the reach area, the fan is switched automatically and operates within the set time period from 2 to 30 min). Reach distance up to 4 m, the max. viewing angle 100°. Mode 1 (single-speed mode) • The fan is turned off by default. The fan starts operating at the 1st speed when the switch is closed or one of the sensors is activated. Mode 2 (single-speed mode) • The fan is turned off by default. The fan starts operating at the 2nd speed when the switch is closed or the sensors are activated. Mode 3 (two-speed mode) Mounting features Installation directly inside a ventilation shaft. Flexible air ducts may be used in case of remote location of the ventilation shaft. Connection of the air duct to the exhaust flange with a clamp. Wall mounting with screws. Suitable for ceiling mounting. Colour modifications 100/125/150 Quiet Aluminum Lacquer VENTS. Domes
