So, I took my thermostat apart to drill the holes in it per the instructions. I didn't think I needed to write down how to put it back together, because seriously, it's like, 3 pieces. Well, I've tried and I've tried but since putting it back together I have yet to get it to shut off. I even turned it all the way down to 90 and it got up to 150 without ever going off. :/ So what did I do wrong putting the stupid thing back together? It should be brainless...there's a little level, a metal disc with writing on one side, and the back. Seriously...how many different ways can there be? Or did I somehow mess the whole thing up while drilling?
