I think (just based on experience), that it kicks the fan up one notch.  In
other words, if the fan's off, it goes on low when you turn on A/C.  If the
fan is on low, it goes on high.  Not certain, but that's usually how it
works on mine.  And if the fan's on high, you're probably headed for
overheating....  :)
