What do the dials on a hot tub do?

What does the air button do on the hot tub?
Air buttons and bellows for spa control systems and panels. Air buttons provide a burst of air through a small diameter hose which activates the air switch. The air switch then converts the air pulse from the depressed button to an electrical signal.
How do I know if my spa has air lock?
