This project has 3 same capacity chiller. The operation scheme is: 0-33% total load ,chiller 1 on. 33%-66% total load chiller 1 and 2 on. 66%-100% total load chiler 1\2\3 on. I tried to use IB_PlantEquipmentOperationCoolingLoad for this case, ironbug generated 3 chilled water loop.
Then run Energyplus , here is the error.
