Thermostats
 Thermostats help your heating and
cooling equipment maintain the optimal temperature setting with the utmost
energy efficiency. Today’s electronic models are a vast departure from
earlier mechanical styles. Microprocessors allow you to program your home
temperatures to suit your lifestyle, so you can keep things comfortable
while you’re home and automatically set back your temperatures to save
energy when you’re away or sleeping.
 Programmable thermostats basically
work the same way, but they are far more convenient. Once you program the
thermostat to customize the system’s operation to fit your lifestyle and
schedule, all you have to do is relax and let it do all the work. You simply
program into its memory the temperatures you need, at what time of the day,
to stay comfortable and save energy all season. You only need to program it
once - until the season or your lifestyle changes.
 The most important way that a
programmable thermostat saves energy is in its setback feature. When you
don’t 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 you’re 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.
