Essential Info

The Honeywell RTH2520B 1008/A Decorator 7-Day Programmable Thermostat offers a 7 day programming with 4 periods per day and it can save you up to 33 percent off your energy bill. You set it up to adjust the temperature when you are away or asleep---times when you don’t necessarily need to heat or cool your home to optimum comfort---and your heating and cooling equipment runs less. This unique 7 day decor programmable thermostat provides the ultimate in style and performance. Three interchangeable covers are included to design the look that matches your decor. The thermostat's blue backlight is easy to read even in dimly lit hallways and rooms. The early start function on this thermostat begins the heating/cooling of your home prior to your programmed times for maximum comfort. This model also includes a filter change indicator that reminds you when it is time to change your air filter. For use with gas, oil, or electric furnaces and AC, single stage heating and cooling or milivolt systems.

    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.

    The customized settings add luxury to your home while affording you valuable savings on your energy bill.

    An Easy Way to Save Energy and Money

    Love it...compact in size, beautiful decor and works replaced an old 1980 Honeywell thermostat which cost 50.00 at the time..I found the old receipt... for the same price this modern unit is a good deal...the only glitch I found was that in the auto smart mode the heat came on very early..maybe I did not give it enough time to learn the house conditions I have it set to turn on half hour early and it does a fine job...easy to self install

    Easy to install, yet the manual that was sent for the programming of the thermostat is not real easy to follow. I called Honeywell and let them guide me through the programming step by step.
