Rated 5 out of
A must buy for thr new modern homeHello I don;t usually write reviews,but this is a must have item for those of you out there who are trying to go green and do a little to save on the power bill every month.Just set this digital thermastat to when, and what time a day that you want the temperature in your home to change and at that precise time your home will be right on that temperature. When your setting hits your set time and you can set it to changs first thing in the morning and to turn down when you leave and set it at 4.00pm when you get home,and set again to go back down at bedtime and set to be nice and warm when you wake up.And even better you have no more cold or hot spots in your home anymore. Plus your saving energy ,and it's energy effecient.One of my better buys,Plus updates my home it alluminates for viewing in the dark. And is real modern looking in your home.And those of you that have emergency heat on your heating system this is exactly the Thermostat that you need.Last and best of all is, that you set the time and days of the week as at your set preferences only one time,And you don't have to keep going back and setting all of the time.your set for the winter..
