Electrical connection of a high-efficiency pump (HE pump)
Speed control of a HE pump is possible via a PWM signal / 0-10 V control. The pump
has to be connected to the relay (power supply) as well as to one of the PWM out-
puts of the controller. In the Outputs adjustment channel one of the PWM control
types as well as a relay have to be selected (see page 37).
