   **   ~~~   ** Please see entry for Timestep in Input/Output Reference for discussion of considerations.
   ** Warning ** Weather file location will be used rather than entered (IDF) Location object.
   **   ~~~   ** ..Location object=UNKNOWN

   ** Severe  ** This building has no thermal mass which can cause an unstable solution.
   **   ~~~   ** Use Material object for all opaque material definitions except very light insulation layers.
   ** Warning ** The Standard Ratings is calculated for Coil:Cooling:DX:SingleSpeed = ZONE1WINDACDXCOIL but not at the AHRI test condition due to curve out of bound.
   **   ~~~   **  Review the Standard Ratings calculations in the Engineering Reference for this coil type. Also, use Output:Diagnostics, DisplayExtraWarnings for further guidance.
