If you press the fan speed button instead, the fan speed will no longer be automatic, and instead will use whatever setting you choose. The vent output will remain auto.
I think for auto to be disabled, you'd have to have a manual vent output selection and a manual speed selection, if I remember correctly. I'd have to check since I always keep it on full auto all the time, so I don't remember what it did the last time I used manual settings.
