10.1.1 Setpoint setting
Set the desired setpoint by pressing or . The setpoint can
be set on any of the pumps in the system and applies to the
complete booster system.
The light fields on the control panel will indicate the setpoint set.
Pump in constant-pressure control mode
Hydro Multi-E systems are as standard set up from factory as
pressure boosting systems, but can be set up to other control
modes. See CRI and CRIE IO 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 29 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.

Setting to maximum curve:
• Press
continuously to change over to the maximum curve
of the pump (top light field flashes). When the top light field is
on, press and hold for
for 3 seconds until the light field
starts flashing.
• To change back, press
continuously until the desired
setpoint is indicated.
Example: Pump set to maximum curve.
Figure 31 shows that the top light field is flashing, indicating
maximum curve.

Setting to minimum curve:
• Press
continuously to change over to the minimum curve
of the pump (bottom light field flashes). When the bottom light
field is on, press and hold
for 3 seconds until the light field
starts flashing.
• To change back, press continuously until the desired
setpoint is indicated.
Example: Pump set to minimum curve.
Figure 32 shows that the bottom light field is flashing, indicating
minimum curve.
