the first code is for display temp , I set it at "ct"s to display the cabin temp, be sure to push the button to the right of the arrows to set it, also find the one for "cdt" set it to 60 again pust the right button to set it , that is clutch delay time in seconds, 60 allows for the engine to warm up and the alternator to charge up the batteries a little before engaging the compressor. I can look and see what the rest are,
