WTF does Max A/C do?

Max A/C is for cabin air recirculation only. Notice when you have a Recirc button, you don't have a Max A/C setting. When you have a Max A/C setting, you don't have a recirc button.

Most compressors nowadays don't cycle anyway. They are either ON or OFF. The pressure control is done with valving in the compressor itself. This is not to say that the engine controller cannot turn OFF the compressore if the high side pressure becomes too high or too low or if you in a W.O.T. scenario.

I have both MAX and re-circ on my 1-Series. Actually, I have MAX and three settings to recirculate air. If I select MAX it drops the selected temp to 60 and does a full lockout to recirculate the air. The MAX selection also locks out the passenger's ability to select their own temp. I'm still trying to figure out the three settings on re-circulation. I might have to RTFM
