Under codes C582 and C592 the hysteresis can be changed withing the range of
0...100 %. The hysteresis refers to the signal at input 2 of the comparator.
If the lower threshold (value of the upper threshold according to input 2 minus value
of the hysteresis) is $ -200 %, the comparator output can be reset via the reset
function.
If the memory function is activated under codes C583 and C593, the comparator
sets the digital ouput when switching for the first time. The digital output can only
be reset using the reset function.
For the time, the reset signal is active, the comparator resets the digital output
independently of the memory function.
