A transfer rate of 9600 and 8N1 (no parity, 1 stopbit) is required for
communication with "Wolf Link pro".
The data described under "Data point list, BMS connection" are of no further
relevance in this case. The "Wolf Link pro" recognises the control unit and
automatically connects all available data points which can be viewed and/or
adjusted via the Wolf portal http://www.wolf-smartset.de.
