switch V. Not applied in case of ceiling mounting.
Speed control is possible through a thyristor

speed controller (see Electrical Accessories).
Several fans may be connected to the same
controller. Speed controllers can not be connected
to the fans with T, TH, TP, VT, VTH modications.
Automatic:
By the BU-1-60 electronic control unit (see
•
Electrical Accessories). The control unit is supplied
separately.
By the T timer (the built-in turn-o delay timer

humidity level in the room exceeds the sensor
threshold adjustable value within 60-90% the fan
switches automatically on and operates until the

shaft exible air ducts may be used. The air duct
is connected to the fan exhaust ange through a
clamp.
Fixed to the wall by means of screws.

to 220 V/50 Hz power mains, it is necessary to
purchase a step-down transformer (e.g. the TRF
220/12-25 transformer).
