I didn't know if I should post this in the "other hardware" Forum or not.

I recently purchased a mini-split Heat and air-conditioning unit for a room in my home. It has an infrared remote for controlling the unit. I figured that I could use My plain old USB-UIRT To learn the functions from the remote control but so far there is no joy. I am told that it's a "complicated" signal. I also have a PIR-1 That I purchased From here a while back but I haven't tried it yet. I am a quadriplegic. Before I start the hunt for the PIR-1 would anybody guess if I'm going to be successful using that Transceiver? Has anyone had any luck programming for these kind of air-conditioning units?
