Note to self: turn the @$%^ fans off when you get out!

I didn't order the thermostatic relay module when I went to electric fans. How hard can it be to turn off the fan when I get out? Well, one trip to Best Buy to buy a surprise gift for my wife and I come out to a dead battery. One $60 emergency roadside service call later and I learned the hard way. Dumb, dumb, dumb! Guess what I ordered today?
