Default setting 103: "Pump pressure control"
DO 0: p0730, ..., DO 2: p0732
Additional settings:
● Differential pressure control using the technology controller
● Technological unit: p0595 = 1 (%), reference variable: p0596 = 1
● Default setting of the technology controller:
● "Flying restart" is enabled: p1200 = 1
● Automatic restart is active. After a power failure, the inverter automatically acknowledges possible
