Tips on saving energy

Central heating
Standard room temperature ("Set room tempera-
■
ture", see page 18):
Never overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Never set your standard room temperature higher
than 20 °C.
Time program (see page 18):
■
Heat your rooms to the standard room temperature
during the day and the reduced temperature at night.
Set the time program for this.
Operating program:
■
If you do not require central heating, select one of
the following operating programs:
"Only DHW" (see page 23):
–
If you require no heating for your home in summer,
but you need hot water.
"Standby mode" (see page 16):
–
If you don't need to heat your home and don't need
hot water for long periods.
Short absence (see page 20):
■
Reduce the room temperature if you are going shop-
ping, for example. For this, select "Economy
mode".
Holidays (see page 21):
■
If you are going away, select the "Holiday pro-
gram":
The room temperature will be reduced, and DHW
heating will be turned off.
Tips for greater comfort

■
ture", see page 18):

Power failure
All settings are saved if there is a power failure.
If the heating system has been shut down for a pro-
longed period, reset the date and time.
Ventilation:
■
Close the thermostatic valves to ventilate. Open the
windows fully for a brief time.
Roller shutters:
■
Close roller shutters (where installed) at dusk.
Thermostatic valves:
■
Ensure that thermostatic valves are properly set.
Radiators:
■
Never cover radiators or thermostatic valves.
DHW heating
DHW circulation pump (see page 24):
■
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set the time
program for this.
DHW consumption:
■
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.
Time program (see page 18):
■
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.
