Direct (the output level of the controller will be > 0, if the
actual value is large than the desired value; e.g. cooling)

actual value is smaller than the desired value, e.g. heat-

A limit for the desired value will prevent entering values
which are outside the determined range. The limits for
desired values do work if the desired value will be input
via the interface. The correction value will be limited for
an external desired value with correction.

Ramp Function / Firing Curve (rAFC)
The device can be used as a fixed value controller with or without ramp function. A firing curve is supported
additionally
