I purchased this same unit almost 20 years ago and it was great. The reason I had to replace it is because although it is programmed to change the temperature at different times of the day my children and I are constantly adjusting the temperature to fit our comfort level and so after about 20 years of this the buttons finely started to fail. This is a great product and I would recommend it to everyone for comfort and energy savings.It will pay for itself in the first year.

This is a replacement of same brand thermostat with older model. The older one was lasted for about 10 years. Like the program functions can use the one stage furnace/AC more energy effective ways. Its easy of use is also a big plus.
