The trigger for sending a telegram to the bus could e.g. be a push button rocker manipulation.
If the 'C' and the 'T' flags of the triggered Group Object are set, then for this Group Object:
- a GroupValueWrite telegram will be sent
- the sending Group Address will be looked up via the Association Table
- the sending Group Address will be put in the Destination Address field of the GroupValueWrite telegram
- the value of the Group Object will be put in the payload field of the GroupValueWrite telegram
