To ensure that the fan operates normally, it is necessary to control its minimum speed of rotation.
Proceed as follows:
• turn the control knob in the counter-clockwise direction to the extreme position without switching the controller off
• switch on power supply
• turn the potentiometer screw by means of an insulated screwdriver (see PIC . 2) until the speed of rotation is
minimal
• turn the control knob to the off position (in the counter-clockwise direction until it “clicks”), wait until the fan stops
• switch the controller to the minimal speed again, the speed of rotation is set to the minimum.
CAUTION!
It is prohibited to control the fan by means of the controller if the minimum speed is not set correctly! Damage to the fan
may result.
• Fix the controller cover and secure it with a nut.
• Replace the control knob.
