I programmed my ACJR to use the up arrow for my heater and when I checked it tonight it was a uppercase U.... I went threw all the settings and redid the programming and it is still there. Any help?

It is likey OK and maybe gone by the time you read this. There is a description of why you see "U" and what condition causes it to appear here:

Perfect thanks! And yes they did go away a few hours later but now I know why :)
