Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.PlantRequests for fan coil units. The three instances of the controller are as follows:

  • plaReq represents a controller instance for a system with both heating and cooling coils.
  • plaReq1 represents a controller instance for a system with just a cooling coil.
  • plaReq2 represents a controller instance for a system with just a heating coil.

Each instance is subjected to an increasing deviation of the measured supply temperature TAirSup from the supply temperature setpoint TSupSet that results in an increasing number of requests from the controllers.
