System design
In addition to the procedure described
under "System configuration" (see
page 47), the system design can also
be amended here or additional com-
ponents and/or functions can be
added or deselected.

Adjusting the required language, see
page 79.

Average time; outside temperature

The average outside temperature is
calculated within the selected period.
This average value is, for example,
the basis of the subsequent data for
the heating curve and for defining the
heating period.
Independent of this value, an average
value is formed every 10 min to safe-
guard the frost protection of the sys-
tem. This value remains unchanged
when the "average outside tempera-
ture" changes.
Heating limit < T room (heating limit temperature)
The heating limit temperature defines
the value of the outside temperature,
below which central heating com-
mences.
