Wiring diagrams
The devices are supplied as standard with an internal potentiometer, this allows the control voltage and desi-
red speed between min. and max. can be set. The delivery includes an internal potentiometer in the terminal
box, which can be used to set any fan speed between min. and max. speed. For an external speed setting
with a 0-10 V control signal, the internal potentiometer must be removed.The diagrams show the potentiome-
ter in principle. It is possible to connect an internal or external potentiometer.
