Note!

The parameters used for the dynamic water pressure limits are not OSV- (out of
service) compatible. Nevertheless, the individual supervisory functions can be
deactivated by setting parameter Dyn superv press diff min (2491) to 0 bar, or
parameter Dyn superv press diff max (2492) to 5 bar. If all types of pressure
supervision are deactivated, only the respective water pressure is displayed

If only dynamic water pressure supervision is required, static pressure
supervision can be deactivated by setting the parameters for the static water
pressure limits to OSV (out of service). In that case, a plausibility check of the
sensor is not made, which means that sensor faults can no longer be detected
since the test is performed by acquiring the static pressure values
