The continuous adjustment of the hydraulic output follows the changing power de-
mand of the system. Changing requirements arise particularly when thermostatic valves
or mixers are used.
The basic advantages of the electronic control system are:
ƒ
Energy savings and reduced operating costs at the same time
ƒ
Reduced number of differential pressure valves required
ƒ
Reduction of flow noise
ƒ
Pump can be adapted to changing operating requirements

4.2.1 Control modes
NOTICE
For details of setting the control mode and associated parameters, see the “Opera-
tion” and “Control mode” chapters.
Selectable control modes are:
Constant differential pressure (
>
p-c)
The control system keeps the delivery head constant at the adjusted differential pres-
sure setpoint H
S
. Control is independent of the volume flow and is applied until the
maximum characteristic curve is reached.
