"you can actually do either. The model expects that the data entered is at 80/67/95 as are the performance curves normalized to that data where the capacity and EIR curves are also 1 at 80/67/95. But if you choose a different rating point (loosely defined as 80/67/95)), and you normalize the performance curves to that point then the model should perform the same. Try it. The only note is that if the performance curves, and therefore the capacity and COP inputs, are not selected at the rating point, then warnings will likely be reported that the curve outputs at the rating point are not equal to 1.0 +- 10%. If this is done correctly at other than 80/67/95 then you can disregard the warnings."
