The heating curve is based on a desired room temperature
i
of 20°C. Increasing the desired room temperature shifts the
heating curve upwards. The degree of shift is influenced by
the setting RT effect.
• RT effect: room temperature factor influencing shift in the
heating curve
• Day temperature limit: outside temperature above which
the central heating is switched off during the day. The
day temperature limit is relevant when the desired room
temperature is higher
than the night temperature that has been set via Menu >
Program > Night temp.
• Night temperature limit: outside temperature above
which the central heating is switched off during the night.
The night temperature limit is relevant when the desired
room temperature is the same as or lower than the night
temperature that has been set via Menu > Program >
Night temp.
11.4 Heating curve – an example
The settings for the heating curve are highly dependent on
the design of the central heating system and the home. This
means that no clear advice can be given on this matter. Use
the tables below as a basic setting if you do not know the
design information. The heating curve can be optimised during
use. The heating curve also shifts upwards or downwards
when the temperature is increased or decreased.
