IHKA also moves the control unit away from the dial to the climate unit itself and can also be controlled for ECO mode driving

I hate to admit it, but I haven't figured out the relationship between the "automatic climate control with enhanced features" described starting on page 133 of the manual, and the "ventilation" described on page 136 of the manual. The climate control has seat heating left and right, control of air flow and where the air enters the cabin. One would think this is all you need. So my question: how does the knob 3 "thumbwheel to vary the temperature" on the ventilation relate to all of this. It seems you control temperature with both automatic climate control and ventilation. If I set the temperature on the automatic climate control, what position should the ventilation thumbwheel be set to, hot or cold?
