4.4 The Control curve
The control curve determines the setpoint value (SP) of the supply tempera-
ture from the measured outdoor temperature.
There are two different default control curves and by setting the DIP-switch 3,
indicating a radiator or floor heating system, you will get the curve that is best
suited for the application.
Control curve (default) for a radiator heating system.
Control curve (default) for a floor heating system.
The control curve is based on three dimension points, defined at the outdoor
temperatures –10°C, +20°C and one adjustable temperature between –9°C and
+19°C.
The corresponding supply temperature of each dimension point is individually
adjustable from the display.
