If you are going away, select the "Holiday pro-
gram" :
The room temperature is reduced and DHW heating
is turned off.
■ Ventilation :
Close the thermostatic valves when venting/airing.
Open the windows fully for a brief time.
■ Roller shutters :
Close roller shutters (if installed) at dusk.
■ Thermostatic valves :
Ensure that thermostatic valves are properly adjus-
ted.

DHW heating
■ DHW circulation pump (see page 25):
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set this via the

Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.
For additional energy saving functions of the Vitotronic
control unit, please contact your heating contractor.
Tips for greater comfort
Central heating
■ Standard room temperature ( "Room temp set-
point" , see page 19):
You can select your individual preferred temperature
at any time in the standard menu.
■ Preferred heating circuit (see page 27):
If your heating system consists of several heating cir-
cuits, you can make any important adjustments for
your preferred heating circuit directly via the stand-
ard menu.
■ Time program (see page 19):
Make use of the time program. In the time program,
you can set time phases with different room temper-
atures, for example different temperatures for day
and night time.
■ Heating curve (see page 20):
The heating curve enables you to individually adjust
the heating system to the actual heat demand in your
home. If set correctly, your preferred temperature will
be achieved all year round.

If you want to heat rooms to a different temperature
from the one set in the time program, select
"Party
mode" .
Example: Late in the evening, the reduced room
temperature is set by the time program. Your guests
stay longer.
