4.1 Setpoint setting
The desired setpoint is set by pressing the button or .
The light fields on the control panel will indicate the setpoint set.
See examples in sections 4.1.1 and 4.1.2.
4.1.1 Pump in controlled-operation mode
(differential pressure control)
Example:
Figure 11 shows that the light fields 5 and 6 are activated, indicat-
ing a desired setpoint of 3.1 psi with a sensor measuring range
from 0 to 6 m. The setting range is equal to the sensor measuring
range (see sensor nameplate).

4.1.2 Pump in uncontrolled-operation mode
Example:
In uncontrolled-operation mode, the pump performance is set
within the range from min. to max. curve, fig. 12.
