CURVE
The control computer shows the value for CURVE by means of a graph in the display. The heat curve can be changed
by adjusting the CURVE value. The CURVE value indicates the supply temperature of the water that is wanted to the
heating system at an outdoor temperature of 0°C.

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 outdoor
temperatures greater than 0°C, a lower setpoint value is calculated.

If the CURVE value is increased, the heat curve will become steeper and if the value is reduced, it will become flatter.
The most energy efficient and cost effective setting is achieved by changing the CURVE value which leads to fewer
starts and longer operating times. For a temporary increase or reduction, adjust the ROOM value instead.
