The set value input REF (terminal X1.17 / version C) can be driven by
various signal levels. It operates cummulatively to the difference voltage
input (terminal X1.8 and X1.9 / version C), but can also serve as the sole
input to the set value presetting. In order to correctly evaluate the signal,
this parameter must be adapted to the signal source.
