[EnergyPlus_Support] Re: No matching inlet or exhaust nodes....
Dear EPlus support,
In hopes of getting a response for this post, I'll re-phrase one of
the questions with more detail...
My system model has a constant volume fan and each zone has a single
Branch with a reheat coil. When I defined this as follows, I receive
the Warning shown below (which does NOT occur when running
"TermReheatZoneExh.idf" from the Example files, even though I've tried
to duplicate the node occurrences):
