I was looking at some Copeland compressors and found that there some family series that have both a CPV and TF5 classification. From what I have read, the "C" stands for capacitor run while the "T" stands for general three phase (also the "5" and "V" both stand for the same voltage which I'll be running 220). So I was wondering if these two compressors are interchangeable or if I am missing something.
