1 heating circuit without mixer A1 (heating circuit 1), 1 heating circuit with mixer M2
(heating circuit 2) and 1 heating circuit with mixer M3 (heating circuit 3), with DHW heating (code
is set automatically)

Coding in the delivered condition

Possible change

11:0

No access to the coding addresses
for the parameters of the combus-
tion controller

11:9

Access to the coding addresses for
the parameters of the combustion
controller open

Note

Setting the code to "11:9" results in
the process circuit being cooled.
This can take approx. 20 min. Only
then is coding address "82" visible.
