[Equest-users] Difference in results for different eQuest versions v3.61 and v3.63 for same model...

[Kendra Tupper]

This is from the bug that was discovered earlier - the fix is to overwrite
the eQUEST default for min cfm ratio (heating). Here is the code that should
be used:

if (#P("HMIN-CFM-RATIO") == unused)
    then unused
    else if (#RV(#P("HMIN-CFM-RATIO")) == 0)
          then #P("HMIN-CFM-RATIO")
          else no_default
         endif
   endif
