I believe the knob you are referring to is the pneumatic cut off (110). It turns on and off the high pressure air. You will see the air pressure (122) valve register when you turn it on.

These I believe are the for cabin air. They may also provide air to clear windshield fogging but I am not sure of that.

I sort of remember threads on this or the SOH forum talking about both of these items.
