Re: [EnergyPlus_Support] Duplicate name for SYSTEM SIZING object

["Michael J. Witte" <mjwitte@xxxxxxxx>]

There is actually two of everything related to SFAN_AH1 in the expidf file.  
System sizing is simply the first one to complain and throw a fatal error.

Looking in IDF Editor, there are two occurences of the COMPACT 
HVAC:System:Unitary object and the COMPACT HVAC:Thermostat.  Looking in the 
text editor, it appears that some of the input file was generated outside of 
IDF editor and pasted in (no endline comments), and the rest of the file has 
end-line comments.  The system and thermostat objects appear in both forms.
