Remove terminal end resistor on A to carry on LON
connection
The LON communication module is factory installed.
Vitotronic 200-H:
The LON communication module (accessory) must be
plugged in.
Refer to the Vitotronic 200-H Installation and
Service Instructions.
The same participant number may not be assigned twice
within a LON.
Example for a multiple-boiler system:
Within a LON, the system numbers (Coding “98” in the
“General” group) must be the same.
Only one control unit may be encoded as fault manager.
The data transfer via LON can take up to several
minutes.
