When the heating company installed my thermostat, a Honeywell T87F, it did not work properly. I called them and they couldn't get to me right away so they suggested I make sure the thermostat was level. It wasn't, so I made it level. I also touched the tiny wires that activate the thing, and as you can see, I'm still alive. There is no way that such small wires could carry enough voltage to harm you.
Now I'm curious, what other dangerous advice have I given, Jon?

Now, I admit I'm not much on computers, but how does that carry over to thermostats?
