F47/Time

f47/Time is a message holding current time of the day in HH:MM:SS format and it's often encountered on Vaillant weather compensators. It usually belongs to "f47" circuit. The message is very useful if the external temperature sensor which comes with weather compensators is not installed or doesn'h have DCF77 signal - in such circumstances, weather compensator's clock goes out of sync very quickly and needs to be often manually adjusted.
