Hi Guys,
I am modelling several VRF systems and I have obtained the capacity data from the manufacturer. I have created capacity curves using the data (input in equest as raw data), but as soon as I assign the curves to my systems, all my results get screwed up. I get nan for space heating for some zones, and all my results are wrong. I tried with different curves posted by other people on the forum (from same manufacturer as mine) with no luck! I went through the equest help file and followed an example mentioning the steps to create performance curves from raw data but still I have problems. Has any one been able to successfully create capacity and performance curves?, and if so, I would appreciate if some one can let me know how they created the curves. Any help is much appreciated.

Regards,

Behnam
