P.S. I'm doing this for better fuel economy.
Basically that knob simply operates the "blend door," which controls whether or not you're getting straight ambient air or whether the air is sent through the heater core, or a mixture of both. If you set it all the way left (cold), the blend door will block off the heater core and you will be getting fresh/ambient air. So it's not warmed up, however it's not air conditioned, either. If the ambient air is very hot, then the air coming through the vents won't exactly be refreshing. It all depends on what you can stand or prefer. But you are correct, it is more efficient than air conditioning, because the engine is not running the A/C compressor in that case.
