Im thinking you mean this screen?
The "button" top left shuts the whole system down and greys out the fan speed, temperatures and other A/C button. So no airflow unless you are moving I guess.
So leaving the top left button "on" you can press the bottom righthand A/C button the red A/C turns white and all the fan and temp options remain active as does the auto "button". So presumably normal heating/ventilation with no compressor running. No idea if it resets to a default a/c on when restarting though.
Also discovered that touching the blue arrows turns those vents on/off, so the same function as a rotary knob distributing the airflow would be in a real car
