The thermal actuator provides smooth opening and closing of the automatic louvre shutters that prevent air back drafting. The impeller design enhances the fan efficiency and prolongs the motor service life. Protection rating IP 24.
MOTOR
Reliable motor with low energy demand Designed for continuous operation and requires no maintenance.		Equipped with overheating protection.
CONTROL
Manual: The fan is controlled with a room light switch (not included into delivery set). The fan is controlled with a built-in pull cord switch "V". This option is not applicable for ceiling mounting. Speed control is possible through a thyristor speed controller (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: Speed control with a an electronic control unit BU-1-60, refer Electric accessories. The control unit is available upon separate order. Fan control with a turn-off delay timer "T" that enables fan running from 2 to 30 minutes after turning the fan off. Fan control with a humidity sensor and turn-off delay timer "TH" that enables fan switching on and running until the indoor humidity drops below the set point adjustable from 60% to 90% and subsequent fan running within the set time before turning off.
MOUNTING FEATURES
The fan is mounted directly into the ventilation shaft. Flexible duct connection is recommended in case of the remote ventilation shaft location. The air duct is connected to the fan exhaust flange through a clamp.		Fixing with screws. Suitable for ceiling mounting. The step-down transformer (TRF 220/12-25) enables connection of a low-voltage fan 12 V / 50 Hz to 220 V / 50 Hz power mains. Available upon separate order.
