For self-service as well as for advance payment (e.g. coins) the pre-selection is set on 1.
Coffee beans are grinded for a pre-selected coffee as soon as the previous brewing process is run-
ning and the grinding position is free.
Example of the display:
Coffee No 4 has been prepared by 40 %, coffee No 2 has been pre-selected 3 times:
