Single pump mode

The control input of the main pump and the control input of the partner pump are respectively occupied with a control cable and configured to EXT. OFF. Each of the two pumps is individually switched by its own control input. If the main pump malfunctions or if the twin-head pump connection is disconnected, the control input of the partner pump is assessed.
Alternatively, a cable jumper can also be put on the partner pump instead of a separate control cable.
