The light fields on the control panel will indicate the specified
setpoint.
Pump in constant-pressure control mode
Hydro Multi-E systems are set up from factory as pressure
boosting systems, but can be set up to other control modes. See
CRE installation and operating instructions. The following
example applies to a pump in an application where a pressure
sensor gives a feedback to the pump. If the sensor is retrofitted to
the pump, it must be set manually as the pump does not
automatically register a connected sensor.
Figure 23 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 43.5 psi (3 bar) with a sensor
measuring range from 0 to 87.0 psi (0 to 6 bar). The setting range
is equal to the sensor measuring range.
