Operation

WARNING! Risk of burns!
Depending on the operating status of the system, the entire pump can become very
hot. There is a risk of burns if metallic surfaces are touched (e.g. cooling fins, motor
housing, pump housing). The setting can be made on the control module during normal
operation by pressing the red button. Do not touch any hot surfaces when doing this.
The pump is operated via the operating knob (fig. 1a, item 1.3).

8.2.1 Setting the control mode and delivery head

The control mode is selected and the desired delivery head set by turning the operating
knob.
Setting the control mode
Variable differential pressure (p-v): fig. 8
The pump for the control mode Δp-v is set at the left of the middle position.
Constant differential pressure (p-c): fig. 9
The pump for the control mode Δp-c is set at the right of the middle position.
Setting the delivery head
The LED display shows the setpoint set on the pump.
If the operating knob is turned to the left or right from the middle position, the set set-
point increases for the respective control mode. If the operating knob is turned back again
to the middle position, the set setpoint is reduced.
Adjustment is done in steps of 0.5 m (up to the delivery head setpoint of 10 m) or in steps
of 1 m (> 10 m delivery head setpoint). Intermediate steps are possible, but are not shown.
Factory setting
The pumps are delivered in control mode Δp-v. Here, the delivery head setpoint is preset
to between ½ and ¾ of the max. delivery head setpoint, depending on the pump type (see
pump data in the catalogue). The required pump output is to be adjusted, depending on
the system requirements.
NOTE: In the event of a power interruption, the delivery head setpoint is retained.
