I tried a simple case of VRF system with EnergyPlus v9.0. I reported the outputs "Performance Curve Input /Output Value" for the VRF model performance curve called "Cooling Energy Input Ratio Boundary Curve", which gave me a result of -999. However, the rest of the cooling curves have good values. In fact, the selection between the low and high cooling EIR curve seems to be following the boundary temperature curve for cooling capacity, not for EIR.
Can anyone confirm if this is a bug or correct me if I am wrong, please?
