   VENTS LINKED TO REMOTE HEAT DETECTORS

   The well insulated room of cold ceiling  is  heated  up  by  hot
   floor.  The  room  dimensions  are  LEN  and  HIG.  When the air
   temperature at the checkpoint of IXP and  IYP  grid  coordinates
   becomes  largee than pre-determined tolerable value,  TLIM,  the
   vents of fixed outside pressures and temperatures are opened  at
   the  room  walls.  The  bulk  air  temperature  in  the  room is
   calculated at the final stage of simulation.

   Two PLANT options,  namely,  Global Summation and Indexed
   Variable Operations are used to make the settings.
