Parameter
Regulation period		Regulation time in seconds. The target/actual comparison is only carried out at this interval.
Hysteresis		Hysteresis.
Hysteresis Typ		With this parameter the hysteresis can be set. plus/minus: IW < SW - hysteresis = on,IW > SW + hysteresis = off minus: IW < SW - Hysteresis = on,IW > SW = off plus: IW < SW = on,IW > SW + hysteresis = off
