They are different
E90 used integrated heating or Air conditioning regulation (IHKR)
F30 uses a integrated heating and air conditioning system (IHKA)
With IHKR the air duct temperature was set to the requested level
With IHKA the air duct temperature will be varied by the control system to get the correct temperature at the temperature sensors in the cabin
IHKA also moves the control unit away from the dial to the climate unit itself and can also be controlled for ECO mode driving
