sorry guys, the code is UA.
My friend went and changed some of the codes ie: 10: 2.01 and I this has caused the unit to stop.

any suggestions.
Is there a list of standard codes which I can re input.
Also when I change the codes how do I ensure the system takes it. As I have gone back to to what my friend have changed but shows the old code

Is this a split system? If so, try 11(21)-0-01, or....

21-0-01 = PAIR (Split)
21-0-02 = TWIN
21-0-03 = TRIPLE

21-0-04 = DOUBLE TWIN
