That buzzer tells you not to use your awning when the temperature is below freezing. The switch your are turning off is the wind sensor. I try to remember to turn mine off every winter and on each spring.

At least we can find them on our coaches. On the last coach I had, they just laid the awning control unit under some cabinets inside the coach way in the back. It took me quite a while to find it and then had to read the manual to determine why it was buzzing.
