1.2.5 Mains supply
The power supply to the controller must be carried
out via an external power switch (last step!) and the
supply voltage must be 100 ... 240 V~ (50 ... 60 Hz). Fle-
xible cables must be attached to the housing with the
enclosed strain relief and the corresponding screws or
be run into the controller housing in a cable conduit
or trunking.

The speed of a HE pump is adjusted through a PWM
signal. In addition to connection to the relay, the pump
must be connected to one of the PWM outputs of the
controller.
Power is supplied to the HE pump by switching the
corresponding relay on or off. The terminals marked
„PWM / 0-10 V“ are control outputs for pumps with
PWM control input.
