Grundfos TPE2 - Setpoint Setting

13.1 Setpoint setting
Set the desired setpoint of the pump by pressing
or . The light fields on the control panel will
indicate the setpoint set.
13.1.1 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 you retrofit the sensor to the pump, set
it up 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 m with
a sensor measuring range from 0 to 6 m. The setting
range is equal to the sensor measuring range.
