I haven't gone into this project for a couple of weeks (away in the Caribbean for a few weeks :)) and it appears now that someone else may have created another project for it or somehow corrupted this one. I have a head family that is being sized, but when I went to identify it (edit equipment), it alerts me that "No models defined for that series." and "Error accessing equipment data in the project." Somehow the software is calculating the flows. What is the easiest and most efficient way to determine what it is so we can re-associate it?
If I can determine the flow, I can probably determine the head family.
