Programmable Thermostats were invented to work as the brain of heating and cooling systems. Today, almost all heating and cooling devices are equipped with a thermostat. First thermostats were analog, which basically had a single function – to turn off the heating or cooling device once the preset temperature of air is reached.

Today, thermostats are a part of making every device in your home electronic or even smart. Digital thermostats allow a greater precision, better control, timer feature for postponed start or turn off, fan speed where fans are used, and much more. The latest technology is the “smart” thermostat – a device which is programmed to learn your heating and cooling equipment usage preferences, and allows you to communicate with it over the Internet from your mobile device.

Thermostats have always been designed to increase your comfort and reduce costs. If you think you don’t need a smart thermostat, you should still learn tricks on how to get the best from your existing one(s).

Programmable thermostats can be used to set the temperature for certain days throughout the week for several regimes. Most programmable thermostats have Wake, Sleep, Leave, and perhaps several other regimes for your basic activities, and you can assign a desired temperature level for each every single day. If you can’t figure out how to program your thermostat, consult this guide from Energy Star.

This interactive guide is much easier for you to learn thermostat programming than reading a buyer’s manual. Once you’ve learned how to program your thermostat, you will be able to master some additional ways to lower your energy expenses. If you could figure once how to program it for a week, you will be able to change its settings whenever you need to, e.g. when you are intending some different times for leaving home, going back or sleeping. A programmable thermostat will also get you save through slight decreases of default temperatures. If you lower the temperature by just two degrees you will most likely feel no difference, but you will save a lot of money throughout the season.

Also, for very cold days, you can set your thermostat to enable heating at relatively low temperatures while you’re away or sleeping. For instance, if you are leaving your home and the outside temperature is just 15-20F, you will not allow the temperature to drop much below “normal” room temperatures, to a point where you need to put very high settings once you come back for a prolonged period of time just to recover the previous room temperature.

But what if you have a different thermostat or a thermostat which can’t be programmed? In these cases don’t rush to turn the heating on high, and don’t put high temperatures, above 70F.
