Debounce fallback warning:
In previous versions the fallback option (automatical setting of a fixed setpoint) was only done for communication timeout scenario in combination with a HUD. It is now also applied in case all sensors are rated as out of bounds. The signaling of the fallback warning (including optional automatic setpoint change) is now done taking a 5 seconds debounds time into account.
In case a fallback warning is active, then the only way to reset it is by selecting a new setpoint or by changing the sensor configuration (no change compared to previous implementation
