[EnergyPlus_Support] Re: Node Connection Error



Hi, 

I'm having the exact same errors : "Construction referenced in 
Hydronic Radiant System surface does not have a source/sink".
However, there is nothing wrong with these surfaces or constructions 
since the idf ran perfectly before I tried to add a low temp radiant 
system.
What could be the problem?

Thanks.
