any adjustments.
Changing the display language
1. Press .
2. Selected the required language with .
3. Confirm with .
Connecting control unit to LON system
If applicable, plug in LON system cable to “LON” connection on module A2.

Data transfer via the LON system can take several minutes.
Setting up LON participant numbers
In code 1 via coding address ”77”.
In a LON system, the same number cannot be allocated
twice.
Updating LON participants
Only possible if all users are connected and the control unit
is programmed to be fault manager (code ”79:1”).
1. Press wand simultaneously for approx. 2 seconds
Participant check initiated (see page 15).
2. Press D.
The participant list is updated after approx. 2 minutes.
Participant check completed.

Initial Start-up
Carrying out a participant check (in conjunction with LON System)
Communication with the system devices connected to the fault manager is tested with a participant check.
Preconditions:
The control unit must be programmed as fault manager (code ”79:1”).
The LON participant number must be encoded in all control units (see page 13).
The fault manager participant list must be up to date (see page13).
1. Press wand simultaneously for approx. 2 seconds.
Participant check initiated.
2. Select the required user with or .
3. Activate check with .
”Check” flashes until its completion. The display and all
key illuminations of the selected user flash for approx.
60 seconds.
During communication between both devices
”Check OK” flashes
”Check not OK” flashes if there is no communication
between both devices. Check the LON connection and
encoding (see page 14).
4. For checking further participants, proceed as described
under items 2 and 3.
5. Press wand simultaneously for approx. 1 seconds.
Participant check completed.
Matching the coding addresses to the system version
In code 2 set the following coding address:
“00” system design
”4C” Connection sÖ on module A3
”4E” Connection gS on module A3
”77” LON participant number
”7F” Detached house or apartment block
”98” Viessmann system number
Note
Further optional adjustments are listed in code 1 and 2.

Initial Start-up
Adjusting heating curves
Heating curves represent the relationship between the
outdoor temperature and the supply temperature. To put it
simply:
The lower the outdoor temperature, the higher the supply
temperature. The room temperature again depends on the
supply temperature.
Settings in the factory default setting:
Slope ”n”=1,4
Shift ”N”=0

Note
For underfloor heating circuits, you can select a maximum
limit, e.g. 45 °C / 113 °F; for this, observe the
system-specific maximum permissible supply temperature.
The maximum limit does not replace the maximum limit
