Operation mode selection and setup for Quiet-Style 100 DC models with modifications T, TH, VT, VTH is performed by setting the DIP switch to a respective position.

Mode 1 (single-speed mode)

• The fan is turned off by default. The fan starts operating at the low 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 high speed when the switch is closed or one of the sensors is activated.

Mode 3 (two-speed mode)

• The fan operates at the low speed by default. The fan switches to the high 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 low speed when the switch is closed and switches to the high speed when the humidity or motion sensor is activated.

Manual control:

• Manual operation with a room light switch. The switch is not included in the delivery set.
• Operation with the integrated pull cord switch V. Not applied in case of ceiling mounting.

Automatic control:

• With the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.
• With the turn-off delay timer T. The built-in turn-off delay timer enables operation of the fan within 2 up to 30 minutes after turning the fan off with a switch.
• With the humidity sensor and timer TH. If the indoor humidity exceeds the set humidity point adjustable from 60 to 90 %, the fan switches automatically to the high speed and operates until the humidity level drops below the set point. After that the fan continues operating according to the timer settings and turns either to the low speed or turns off.

• Installation directly inside a ventilation shaft.
• Flexible air ducts may be used in case of remote location of the ventilation shaft. The air duct is connected to the exhaust spigot with a fixing clamp.

• Wall mounting with screws.
• Suitable for ceiling mounting.
