is set (see page 7), central heating
takes place during the holiday
program with the selected ”reduced
room temperature” (see page 8), but
without domestic hot water heating.
The preset time program for central
heating and domestic hot water is
active on the dates of your departure
and return.

preset heating program on the dates
of your departure and return.
Please note:
The control unit is set up so that
the holiday program is effective
for all heating circuits.
If you require this to be changed,
