the same type.
Makes the pump ready for operation/starts
and stops the pump.
Start:
If the button is pressed when the pump is
stopped, the pump will only start if no other
functions with higher priority have been
enabled. See section 16. Priority of
5
settings.
Stop:
If the button is pressed when the pump is
running, the pump will always be stopped.
When the pump is stopped via this button,
the "Stop" text next to the button will
illuminate.

9.1 Setpoint setting

Set the desired setpoint of the pump by pressing
The light fields on the control panel will indicate the setpoint set.
9.1.1 Pump in differential-pressure control mode
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 up manually as the pump
does not automatically register a connected sensor.
Figure 15 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 4.3 psi (3 m) with a sensor
measuring range from 0 to 8.5 psi (0 to 6 m) The setting range is
equal to the sensor measuring range.

9.1.2 Pump in constant-curve control mode
In constant-curve control mode, the pump performance will lie
between the max. and min. curve of the pump. See fig. 16.

Setting to max. curve:
• Press continuously to change over to the max. curve of
the pump (top light field flashes). When the top light field is on,
press for 3 seconds until the light field starts flashing.
• To change back, press continuously until the desired
setpoint is indicated.
Example: Pump set to max. curve.
Figure 17 shows that the top light field is flashing, indicating max.
