Doesn't pressing a fan or distribution button over-ride the air distribution controls, it still controls the temperature automatically.
Oddly enough I never appreciated one of the Climatronic's features until the passat went (same system) on auto/econ it will not put air onto the windscreen until the cold damp air in the system from overnight has been cleared (into the footwell). On cold mornings the Honda steams up - the A2 and Passat do not!
