    Convenient and Efficient for At-Home Comfort
    You know that turning down your heat at night saves you money, but you hate waking up and making breakfast in a freezing cold kitchen. Or you don't want to run your AC all day while you're at work, but you want your home to be cool and comfortable when you get home. That's where a programmable thermostat makes all the difference.

    Excellent product. I purchase one originally and when I liked it I bought 2 more for the rest of the house. Note though. My old programmable kicked on at the time I requested the temperature change. This one starts early enough so that the temperature you select is met by the time you requested it. So I had to set my times a little differently since the 5-1-1 does some of the thinking for you. You won't be disappointed.
