The system will deduct this pressure value from the target
pressure in order to specify the start pressure of the pump.
Example:
Target pressure (P-SET) 3.5 bar
-
Differential pressure 0.3 bar
=
Start pressure 3.2 bar
This value is 0.3 bar by default.
With in-house facilities it is recommended to keep this value
between 0.2 bar and 0.5 bar.
With irrigation systems, it may be sensible to select a lower start
pressure.
0.3 bar
If the control of the pump has detected that no consumer is
opened any more (flow detection FL = 0), the pump will be
stopped after the set TIMER STOP. The TIMER STOP must not
be selected to be too short so that the pump keeps on running
also in case of little water withdrawal and does not change into a
steady start-stop operation.
