Tips on saving energy
Central heating
■ Standard room temperature ("Set
room temperature", see page 25):
Never overheat your home. Every
degree of room temperature reduction
saves up to 6 % on your heating bills.
Never set your standard room temper-
ature higher than 20 °C.
■ Time program (see page 26):
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 31):
If you require no heating for your
home in summer, but you need hot
water.
– "Standby mode" (see page 23):
If you don't need to heat your home
and don't need hot water for long
periods.
■ Short absence (see page 29):
Reduce the room temperature if you
are going shopping, for example. For
this, select "Economy mode".
■ Holidays (see page 30):
If you are going away, select the "Hol-
iday program":
The room temperature will be reduced,
and DHW heating will be turned off.

■ Ventilation:
Close the thermostatic valves to ven-
tilate. 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 32):
Only activate the DHW circulation
pump for periods in which DHW is reg-
ularly 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.
