Description of the individual set point types
Set point type/function Description
Hysteresis For every set point, the switch point can be controlled via a hysteresis.
The hysteresis is set as an absolute value (positive values only) in the unit of the respective channel (e.g. upper
set point = 100 m, hysteresis = 1 m: Set point on = 100 m, set point off = 99 m).
Upper set point The limit value is active if the value exceeds the configured value. The limit value is switched off if the limit
value, including hysteresis, is undershot.
