Setback mode (reduced heating mode)
See "Reduced heating mode".
Operating program
You define the following with the operating program:
■ Central heating and DHW heating
or
Only DHW heating, no central heating
■
or
■ Only frost protection for the boiler and the DHW cyl-
inder is active.
No central heating, no DHW heating
Note
No operating program is available for central heating
without DHW heating. When you want central heating,
hot water is generally also required (winter mode).

Operating status
In the operating program "Heating and DHW", the
operating status changes from "Standard heating
mode" to "Reduced heating mode" and vice versa. The
times at which the operating status is changed over
are defined by you when setting the time program.

Screed drying
Your heating contractor can activate this function for
screed drying, for example in your new build or exten-
sion. This means your screed is dried in line with a
fixed time program (temperature/time profile) that is
appropriate for the building materials used.
