Service menu
The menu of the user interface is adapted to your system
automatically. Some menu items are only available if the
system has been set up accordingly and the user interface has
been set correctly. The menu items are only displayed in
systems in which the corresponding system components are
installed, e.g. a solar system or a heat pump. The
corresponding menu items and settings can be found in the
respective operating instructions.
If a CR 100 is assigned to a heating circuit as remote control,
the available setting options at C 400/C 800 for the
corresponding heating circuit are limited. Some settings that
can be changed via CR 100 are not displayed in the C 400/
C 800 menu. Further information about the affected settings is
available in the operating instructions for CR 100.
Information about the operation of the service menu is
summarised in Chapter 4, from page 14.
After a prolonged power failure or shutdown,
the date and time might have to be reset. All
other settings are retained permanently.
The default settings are highlighted in the
adjustment range column
