Using a thermostat to control a window air conditioner is easier than it sounds. Just go to radio shak and get two 10 amp relays that can be triggered by 12 volts. Wire up the fans and the compressor to the two relays and hook them up to the thermostat. The yellow terminal usually means compressor and the green therminal usually means fans, but check online to make sure.
