RE: [EnergyPlus_Support] Re: Controller error messages
Perhaps you missed the tool HVAC-diagram.exe that is distributed with the current release.
It should be located in the directory ..\EnergyPlus\PostProcess\ . It processes output from EnergyPlus and makes a .SVG file that diagrams the main parts of the HVAC system.

Thank you, Linda.
Another question: in a previous post you mentioned an in-house
version of E+ that shows the node-branch-loop connections. I spent so
much time trying to get these straight in this model. Will a utility
program like HVACDiagram be coming out soon?
