I'm going through the example files provided, and noticed that at least for "5ZoneWaterLoopHeatPump.idf" equipment sizes are specified in the file.  I tried making an equivalent file from scratch, with only two-zones and allowing auto-sizing.  The simulation crashes, giving me the error below, among others.  If I set the equipment sizing to match the example file, the program runs, although with some significant warnings (my two zones are much smaller than the example file's zones).

What are the guidelines for auto-sizing of equipment?
