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 regulator unit. 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.
Mounting features
