tech manual needed controler out of safety zone
That usually means you have a mechanical problem. Like a clogged condenser or condenser fan problem. The only time you would need to change the controller parameters is if it was new to the machine. And if it's OEM, it's already programmed.
I think you must mean a URT, not UTR. This is the only thing I could find on it.
