Example: Set value (standard 40°C).
In the event of outdoor temperatures below 0°C, a higher setpoint value is calculated and in the event of out-
door temperatures greater than 0°C, a lower setpoint value is calculated.
Moving the heat curve as one unit
When the curve indicator
40
is lit, the curve is moved as one unit and the slope of the curve is adjusted.
The simplified working principle for this is as follows:

If the curve is moved upwards, the heat curve will become steeper and if the curve is moved downwards, it will
become flatter.
The most energy efficient and cost effective setting is achieved by changing the curve settings which leads to
fewer starts and longer operating times.
