1.2 Possibilities for energy saving

Limiting the room temperature
Limit the room temperature to the minimum value at
which you still feel comfortable. Every degree above
this represents an unnecessary additional consumption
of energy by about 6%.
Lowering the room temperature
Lower the room temperation during the night or
periods of absence.
Extending the drop periods
The heating system is to start on hour before you will
have a demand of heat. The heating system is to shut
down at least one hour in advance of the time up to
which you would like to keep it warm. Due to the
hermal inertia of the building, the room temperature
will only drop gradually.

Ventilate briefly but thoroughly
During the heating period, open windows only for
airing and not for regulating the room temperature.
A brief but vigorous airing is more effective and more
economical than keeping windows slightly ajar for
longer periods. When airing, set the operating mode
switch (1) to , this will prevent your heating system
from switching on unnecessanly.
Keep the room thermostat clear
Do not obstruct your room thermostat with furniture,
curtains or other objects so that its sensor is fully expo-
sed to the circulating room air.
Fully open the radiator valves
Always keep fully open all radiator valves in the room
in which your room thermostat is situated.
