fied by inputting these in chronological order.

4.7.2 Programming holiday periods
For a longer period of time when you are not at home,
you can define a lower room temperature. This will save
heating energy. The control ensures that the appliance
heats up the living rooms only to this room tempera-
ture.
You can specify a room target temperature of 15 °C if
you wish to go on holiday from 10 - 24 February. The liv-
ing rooms are only heated to 15 °C during this period.
You can also select the frost protection function instead
of a room temperature.
Proceed as follows to programme a holiday period:
Turn the left-hand dial until you reach screen 7
"Holiday programming for whole system".
