ating program":

and the DHW cylinder is active.

Setting the "Holiday program"
Factory setting: The holiday program applies to all
heating circuits.
Note
Your system is factory-configured as a "Detached
house". All heating circuits in your system are
assigned to a house or home.
If you want to assign your heating circuits to individual
homes, your contractor can change this setting to
"Apartment building". The "Apartment building" setting
allows you to select the heating circuits, and therefore
the homes, to which the "Holiday program" applies.
Tap the following on-screen buttons:
1. If required, for the home screen
2. for the "Main menu"
3. "Holiday program"

Note
The "Holiday program" starts at 00:00 h the day
after the departure date. The "Holiday program"
ends at 00:00 h on the return date. This means
that the set "Time program" is active on the
departure and return dates.
