Set the application module as described there.
5.4.3.3
Cascade mode with one pump group
In cascade more, the pumps are switched on and off in stages depending on pre-
set speed thresholds.
If the upper speed threshold is exceeded, the pump controller switches another
pump on to complete the conveyance task. If the lower speed threshold is not
reached, the pump controller detects that it the flow rate with fewer pumps and
switches a pump off.
The compensation task is taken on by all active pumps.
