[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.
