Selecting Energy Saving Function "Holiday Program"

Comfort and Energy Saving Functions
To save energy, for example over long holidays, you can
activate the "Holiday program".
Make the settings for this energy saving function at the
Vitotronic 300-K.
Note: The control unit is set up so that the holiday
program applies to all heating circuits. If you
want to make changes, contact your local heating
contractor.
The holiday program has the following effect on the
heating circuits and DHW heating:
H Central heating:
- For heating circuits in the heating program "Heating
and DHW": In these heating circuits, the rooms are
heated to the selected reduced room temperature
(see page 17).
- For heating circuits in the heating program "Only
DHW": No central heating in these heating circuits.
If the heating program "Only DHW" is selected for
all heating circuits, frost protection monitoring is
only enabled for the boiler and DHW tank.
H DHW heating:
DHW heating is switched OFF; frost protection for the
DHW tank is active.
The holiday program starts at 00:00 h the day following
your departure and ends at 00:00 h on the day of your
return. This means the selected time program is active
on the days of departure and return (see page 18).
