effect:
The room temperature during the periods between
the set time phases is raised to the set value of the
first time phase of the day: From reduced room tem-
perature to standard room temperature or comfort
room temperature.
If no time phase is active before 0:00 h, your rooms
are heated to the reduced room temperature until the
next time phase becomes active.
DHW heating is active.
The "Holiday at home" function starts and ends
according to the set times for the start date and end
date.

switched on, the default display shows "Holiday at
home" and the set start date and end date.
If "Detached house" was selected by your contrac-
tor during commissioning, the function is adopted for
