In some cases, this type of error can occur during cooling coil iterations, and 
it has no impact on the results.  In other cases, this could indicate that 
conditions in the zones or air loop are out of range, and the results may not 
be valid.  It is impossible to tell without running the file here.  Please 
upload to the files area in the Problem_Submittals folder.
