We finally got our nest thermostate this week and I setup it in less than a half an hour on friday night. It's amazing. It's a smart thermostate which will learn our patterns of how cool and warm we like the house. It's primary function is to lower our heating bill. It's amazing, you can control it from your computer, cell phone and iPad. SWEET! On the way home last night I checked to see how it was doing and turned on the air to drop the house temp just a little. Heaven!!!!!!!!
