When the system works in Floating proportional mode, the ON working time is fixed (On Time),
where as the OFF time starts from a maximum (Maximum off time) and it is gradually reduced
according to the cold and hot band width (Closed band and Open band).
Example. In the middle of the Closed band, OFF time is 50% of Maximum off time.
The minimum OFF time is never below the On Time.
When in the neutral band (Neutral band) the system is OFF.
Beyond the Closed band and Open band the system is always ON.
