I wanted to input actual chiller performance curve using HVACTemplate. That's why I used HVACTemplate:Plant:Chiller:ObjectReference with HVACTemplate:ChillerWaterLoop and Chiller:Electric:EIR. Howerver, I got fatal error because I didnt fill in Chilled Water Inlet Node Name and Chilled Water Outlet Node Name. However, I expected that I dont have to worry about Inlet and Outlet because HVACTemplate will take care of it. Does anyone know how I can use HVACTemplate:Plant:Chiller:ObjectReference with Chiller:Electric:EIR?
I added corresponding part in idf as below.

I think that should work. Could you send me the file you are having a problem with? jglazer at gard dot com

I faced the exact same problem. I solved it by inputting not only Chilled Water Inlet Node Name and Chilled Water Outlet Node Name, but also Condenser Inlet Node Name and Condenser Outlet Node Name. Any Node name is fine, but blank is not acceptable for these four fields.
