8.1.1 Setpoint setting
Set the desired setpoint by pressing
set on any of the pumps in the system and applies to the complete
system.
The light fields on the control panel will indicate the setpoint set.
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 CRI and
CRIE installation and operating instructions. The following example
applies to a pump in an application where a pressure sensor gives
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.
The figure below shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 3 bar with a sensor measuring range
from 0 to 6 bar.
The setting range is equal to the sensor measuring range.
