4.6 BUS connection
As part of the BUS cable connection, not only
the electrical interconnection for the system
communication will be created.
Only connect the BUS cable during
commissioning.
The correct BUS connection has a vital influ-
ence on the function of the heat pump system
(see sections 5.1 and 6.1)
