The behaviour is factory-programmed. If another switching function
is wished, the pump can be reprogrammed in the
‘Relay’
menu.
The variable to be signalled for the current output can be selected
in the
‘ANALOGUE OUTPUT’
menu.
The current output plus relay can be retrofitted and operates once
it is plugged into the board.
