Energy saving tips

Saving energy when using central heating
Do not overheat your home. Every degree of room
■
temperature reduction saves up to 6 % on your heat-
ing bills.
Weather-compensated operation and room tempera-
ture-dependent operation:
Never set your standard room temperature (standard
temperature level "n2") higher than 20 °C.
■ Heat your home to the reduced temperature at night
or during regular absences:
– Weather-compensated operation:
Reduced room temperature
Continuous operation and room temperature-
–
dependent operation:
Reduced flow temperature
In constant operation, adjust the time program for
central heating; see page 18.
In room temperature-dependent operation, time pro-
grams for central heating can only be adjusted at the
room temperature controller or OpenTherm control-
ler.

Saving energy on DHW heating

is always sufficient hot water in accordance with your
habitual routines: See page 19.
Example: You need more DHW in the morning than in
the daytime.
