Xylem hydrovar User Manual

This parameter sets the pressure control mode for the pump system (single and multi
pump): depending on the setting ("Constant" or "Differential") a set of further parameters
are automatically configured.
Whenever P1311 CONTROL MODE is set to a new value, each parameter in the below
table is overwritten to its own specified value, regardless of previous different settings.

Sets the end range value (20 mA or 10 V) of the connected sensor. In particular, the end
range value (20 mA or 10 V) must be always equal to the 100% of the sensor range (that is,
for a 0.4 bar differential pressure sensor, is 20 mA=0.4 bar).
