Setting the control functions
Additional settings can be made in the context menu. For this purpose, press the Con-
text button .
Press the Back button
You can already make additional settings at the pump during the venting process.
These settings become active when the venting process is completed.
NOTICE
Any set control mode is interrupted while a process is running. After completing the
process, the pump continues to run in the set control mode.

Repeatedly pressing or pressing and holding the Back button after an error message
has occurred will open the "Error" status display and not take you back to the main
menu.
The status area is highlighted in red.
Basic control functions are available depending on the application.
Select control functions using the settings assistant:
▪ Differential pressure ∆p-c
▪ Differential pressure ∆p-v
▪ Index circuit ∆p-c
▪ Dynamic Adapt plus (factory setting at the time of delivery)
▪ Volume flow constant (Q-const)
▪ Multi-Flow Adaptation
▪ Temperature constant (T-const)
▪ Differential temperature (∆T-const)
▪ Speed constant (n-const)
▪ PID control

Constant speed (n-const / constant speed)
The speed of the pump is kept at a set constant speed.
Differential pressure ∆p-c
The control keeps the differential pressure created by the pump constant above the
permitted flow rate at the selected differential pressure setpoint H
mum characteristic curve.
Index circuit ∆p-c
"Index circuit ∆p-c" function is used to control a distant measuring point with an ex-
ternal differential pressure sensor. In this process, so-called ∆p-c control is applied.
This function is suitable to ensure a differential pressure at a distant point in the sys-
tem.
Differential pressure ∆p-v
This control mode triggers a linear change in the differential pressure setpoint the
pump must ensure between reduced differential pressure H and H
Consequently, controlled pressure H increases or decreases with the flow rate.
