Oh wow, that _is_ a fancy air conditioner. And yeah, the keyset I've currently got doesn't match the keys on the remote, but the config file from the hifi-remotes website looks like it might be a match. (It looks like each key on the remote can take on three or four different values. This protocol will be fun to decipher. ) I'll cobble together a keyset out of it and see what you think...

EDIT: This protocol will be _real_ fun to decipher. If you're interested, take a look at the real IR experts scratching their heads over it in this thread.
