DIYbanter - Temperature and volume

When watching TV in my family room, if I'm feeling a little warm, I just
turn down the volume on the stereo receiver. If I'm too cool, I turn up
the volume. Honest, that is how it works.

After the power surge damage, I rep laced the TV and sound system. Last
night we were watching a movie and the room AC was on so I turned up the
volume to overcome it. A few minutes later, the AC shut off and the TV
seemed loud, so I turned it down. Soon, the AC was back on so I turned
the volume back up. After repeating this one more time, my wife noticed
what was happening.

The AC has a remote to control a few functions. The new receiver has a
remote with many functions. Coincidently, the volume of the sound
system is the same signal as the temperature on the AC unit so I was
moving them both up and down at the same time.

I thought this was going to be about thermal expansion and contraction.
