Hi Ernie,

I’m sorry for any misunderstanding, my name is Alaa Masry and it is just my nick name is ScOrPiO.

Anyway, I have the TSU 9800 and I installed it in my office where I have Carrier AC (model details mentioned earlier) and I need to control everything through the TSU, and I have the original Remote control of the AC , but the problem is as mentioned in the previous quotes that whenever you adjust anything using the Remote control it sends back all the settings to the AC not only what you adjusted, and I would like to duplicate this IR signal to transmit it from my TSU, so I was wondering if anyone can help me on this issue.

Thanks again.
