Operation modes of the fans models VENTS Quiet-Disc 150 and VENTS Quiet-Disc Extra 150 with modifications T, TH, VT, VTH, TP are selected by setting the DIP switch into the required position.

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)

• 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.

Mode 4 (two-speed mode)

• The fan is turned off by default. The fan starts operating at the 1st speed when the switch isclosed and switches to the 2nd speed when the humidity sensor is activated.

Mode 5 (two-speed mode)

• 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.

Manual control:

• Manual control with a room light switch. The switch is not included in the 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 a P2-1-300 speed switch (only for VENTS Quiet-Disc 150 models), see Electrical Accessories. Several fans may be connected to the same controller. Speed controllers can not be connected to the fans with the T, TH, TP, VT, VTH modifications.

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 turn-off delay 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°.

• 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.
