5. Integrate the control unit in the LON BUS system in conjunction with Vitotronic 200-H
The LON communication module (accessory) must be inserted (see page 96).
Set the LON participant number
Set the LON participant number via
coding address ”77” in coding 1
(factory setting: ”77: 1”).
See page 114 for coding 1.
Please note:
The same number must
not
be
assigned twice within a LON BUS
system.
Update the LON participant list
This is only possible when all participants are connected and the control unit is
coded as the fault manager (coding ”79: 1”).
