I have discussed that IR protocol in a few other threads. I don't remember all the details and I don't have time today to search for those threads. (But you might try a few forum searches to find them).

So far as I recall, we determined that the signal as you posted it is not the whole signal. It was truncated to the maximum length that a Pronto can learn. I don't recall what results we had from attempts to reconstruct the full signal.

What does the air conditioner do when you use the learned signal that you quoted above? (Same or different from what it does when you use the original remote?)
