Setting up a holiday program

Menu: Holiday
If you leave the house for several days or if you have several
days' holiday, you can set the holiday program. If the heat pump
is in heating mode according to the settings for summer/
wintertime changeover, the holiday functions are used. Thus
you heat particularly economically for the duration of the
holiday program or with a time program like "as Saturdays" or
you do not heat at all.
Regardless of the settings you make for the
holiday program, cooling mode will not be
activated during your holiday.
You can optionally switch off DHW heating completely for the
duration of your holiday. The factory settings ensure energy
efficient and reliable operation during your holiday. During the
holiday period, the display indicates when the holiday program
will be active until.
