[EnergyPlus_Support] Re: Non-Zone equipment and Boiler in series
I searched the input files and made sure there were no typos - i
think the error was that I was mixing demand-side components with
supply-side ones (I thought a boiler could be on the demand side as
well), and for some reason it didn't reconognize that as the error.
I never got an errors mentioning invalid equipment configurations -
just the node connections. And I went through and cut and pasted my
node names in their respective places to make sure they were typed
exactly the same.
