I have got these errors after run an air cooled chiller simulation. Please help me figure them out. How can I fix these errors. Thank you.

If you look at the Energy+.idd you will find the AirLoopHVAC:ControllerList object. And also find this object in your input file. This object is a list of controllers used in your simulation and consists of a list of controller TYPE and NAME pairs. For an air loop (AirloopHVAC object) you can have water coil controllers and an outdoor air system controller. There would typically be an outdoor air system (that's 1 controller) and up to 7 more water coils. You should not need more than 7 water coils in an air loop. For that reason, EnergyPlus has limited the number of controllers to 8 per air loop. Your error message seems to indicate that more than 8 controllers are listed in this object. Since this object is not "extensible" (meaning you could expand this list in the IDD and include more than 8 controllers) you can only use up to 8 controllers. Look at your input file and determine why there are more than 8 controllers in this list.
