Display in double pump operation
Each double pump partner has its own graphical display showing the values and settings.
On the display of the main pump with a pressure sensor mounted, the home screen is vis-
ible as for a single pump. The SL feature is shown in the setpoint display field on the display
of the partner pump without the pressure sensor installed.
When a double pump connection is established, entries on the graphic display of the part-
ner pump are not possible which is visible by a lock symbol on the ‚Main menu symbol‘.
