When selecting OFF and a demand for refill occurs, the controller
for the actual circuit sends the requirement via the ECL 485
communication bus to the master controller.
The master must be running an application with refill water function.
The master starts the refill water pump and sends, via the ECL 485
communication bus, a message that the refill water pump is started.
The refill water valve then opens.
The slave must have an address 1 ... 9.
