PROGRAMMABLE THERMOSTATS basically work the same as electronic thermostats with more features for comfort, efficiency and convenience. Simply program the temperatures you need, and the times of day you need them, to stay comfortable and save energy all season. You only need to program it once -- until the season or your lifestyle changes.
Energy Savings
The most important way that a programmable thermostat saves energy is in its setback feature. When you dont need a normal level of heating or cooling, you can program the thermostat to set the temperature back until the next pre-programmed time when you want normal temperatures. Programming temperatures around 63 F on cold winter nights, when youre snuggled under blankets, can help you save as much as 15% on your heating costs. You can save even more by programming your system to "setback" the temperature when your family is away at work, at school, or on vacation. In summer, setbacks work much the same way for central air conditioning.
