Displays in the code layer

The Code layer has different areas in which you can
change parameters or merely view them, depending on
the context. The context can always be recognised from
the menu name.
Menu C: Set parameters for the heating system
Menu D: Perform diagnostics
Menu I: Display general information
Menu A: Installation assistant
Your code entry is reset again 15 minutes after your last
change in the Code level (actuation of one of the dials).
To gain entry to the Code level again after that, you will
have to enter the code once more.
