This submenu defines parameters for multi-pump systems.
application example:
1) Lead pump reaches its ENABLE FREQUENCY [0515]
2) Actual value falls and reaches the cut in-value of the 1st assist pump Cut in-value = REQUIRED VALUE
[02] – ACT. VAL. DEC. [0510] → the 1st assist pump is switched on automatically
3) After the start up the new required value is calculated in the following way:
NEW REQUIRED VALUE = REQ. VAL. [02] – ACT. VAL. DEC [0510] + ACT. VAL. INC. [0505].
The new required value is shown in the main menu as parameter EFF. REQ. VAL. [03].
