Heater settings!

[torqueofthedevil]

On my e46 you can set the temperature on the digital setting but then if you change the manual dial above (between the blowers) this seems to over ride it?!?! How are these two settings supposed to be used?

The dial only sets the temperature of the air being blown at the drivers face, the rest of the vents continue to blow the air out at the set temperature.

The purpose of the dial is so that you can prevent yourself from becoming drowsy at the wheel whilst driving when the temperature is raised on the heating system by having cold air blown on your face.

The digital temp setting is for climate/temp control. The manual dial I think you are referring to changes the vents to go from heated air (which is controlled by the digital temp readout) to unheated or fresh air which is not affected by the temp control.
