Unfortunately, it is a fact that most users need a few weeks to become 
productive with TRNSYS, unless they attend a training course (or several 
training courses). I think it is safe to say this is true of any 
detailed and flexible simulation program for energy systems and buildings.

Assuming you have ordered the components correctly (Type 9 before Type 
16), that error is most often caused by a missing connection between 
outputs 99 and 100 of a data reader (time of last and next data read) 
and the corresponding inputs of Type 16. Those inputs tell Type 16 when 
new solar radiation values are read so it can redo the processing only 
when needed.
