Using A Programmable Thermostat
One of the best and least expensive ways to lower your utility bills all year round is to replace the manual thermostat in your home with an electronic programmable thermostat. Installing a programmable thermostat is not a difficult home improvement project if you follow the directions for your model of thermostat closely. If you’re not comfortable doing it then most heating and air conditioner repair companies will install it for you at a very reasonable price.
The advantages of a programmable thermostat are pretty easy to see. Electronic thermostats will automatically turn the hear or air conditioner on or off throughout the day according to your instructions. This gives you the ability to only use the utilities when you need them and when you’re home.
For example: lets say you leave for work at 8:00AM every morning and don’t get back until 5:00PM each day during the summer. You can program your thermostat to let your house get to 80 degrees during the day and then have it automatically turn on and cool the house back down to 74 degrees as you walk in the door each night! In a single season a programmable thermostat could pay for itself by saving you hundreds of dollars in electric bills. Many programmable thermostats now allow you to actually set different temperatures and times for the weekends and weekdays.
And, as an added bonus, you don’t have to worry if your schedule changes from time to time. You can always “override” the program temporarily and set your temperature to whatever you’d like it to be when you’re actually in your home.
Most programmable thermostats use batteries to power their display, so the only real maintenance you’ll ever need to do is replacing those batteries once a year or so. Many thermostats now have low battery indicators as well as reminder indicator that blinks when it is approximately time to change the house air filter.
Choosing A Programmable Thermostat
There are several options you can consider when you’re looking to purchase a programmable thermostat. Though they are all fairly affordable, there is still quite a price range for them. You can expect to pay anywhere from $20 for the most basic models to about $150 for the most advanced programmable home thermostats. Here are some of the options you want to look at before you buy a programmable thermostat:
System Type: When buying an electronic thermostat you’ll need to be sure you choose one that will work with your heating and cooling system. Generally, there are three options here. You may have a single stage system which is often found on traditional heating and cooling systems for a single house. You may have a gas heating system and an electric central air system and you can only operate one or the other at any one time with your automatic thermostat. Multi stage systems control two or more types of heating systems (one main and one secondary) and you’ll typically know that you have this. Another common system type is a heat pump which is a single system that can both cool and heat your home.
Programmable Days: There are generally three varieties of programmable thermostats – 1 day, 5 day and 7 day programmable thermostats. Single day programmable thermostats usually allow you to set the temperature for 3 to 4 different periods through the day, but they treat each day exactly the same. You can’t have any sort of differences in temperatures on weekdays or weekends. The 5-2 programmable thermostats allow you to set your weekdays differently from your weekends, but they tend to only let you set all your weekdays the same and then both weekend days with the same time and temperature schedule. There are also 5-1-1 programmable thermostats that treat Monday through Friday as the same, but allow you to set different times and temps for Saturday and Sunday independently. The most common, and only slightly more expensive electronic thermostats are 7 day thermostats which give you the option to set each and every day of the week differently. These are becoming more and more common and affordable. Most digital thermostats allow you to program 3 to 4 temperature changes in a single day and you can set the times to meet your schedule.
Extra Functions: There are lots of extra features and functions you can get in electronic thermostats. Some will control multiple systems, some allow you to control a whole house humidifier and some allow you to hook up an outdoor temperature sensor. A few even allow you to save multiple program types so you can just pick and choose as needed.
Interface Type: Most automatic and programmable thermostats sold now feature digital readouts on easy-to-read LCD screens. Backlit screens are easier to read at night or in dim lighting, obviously. You can get touchscreen thermostats, button-controlled thermostats and even remote-controlled thermostats. Today’s programmable thermostats are almost exclusively housed in white or beige plastic casings with rounded corners. Yes, you can paint or even wallpaper over electronic thermostats, but doing so is generally not recommended as it could interfere with the temperature gauges in most electronic thermostats.
Programming a Thermostat
While different brands and models of thermostats are obviously programmed with different specific steps, most programmable thermostats these days are pretty easy to operate.
You will often have to set up a schedule initially, which usually consists of going through each day and setting the appropriate times and temperatures you want your house to reach. Some electronic thermostats will only allow you to turn on one system at a time: heat or AC. So if it’s cool in the morning but expected to get hot in the afternoon you might want to turn on your AC and program it to kick on before you get home.
Using A Programmable Thermostat
Manually adjusting and using a programmable thermostat isn’t much different from any other type of thermostat. Most have an “up” and “down” button which allows you to control how you want the temperature to change: warmer for up and cooler for down. Some people believe that if you move the temperature higher or lower than you really want it that the heating or cooling system will “work harder” to reach the real temperature goal, but that simply isn’t the case. Almost all heating and cooling systems have two simple settings: on and off.
Most digital thermostats will give you a read out of the current temperature in the house (or temperature at the thermostat itself) and they will all allow you to manually override whatever the programmed temperature is. So if you take a day off in the middle of the week when you normally wouldn’t be at home you can adjust the temperature to your liking. When the next time period and temperature change comes, most programmable thermostats will go back to following the program.
If you have a forced-air heating system or central air conditioner then you can usually manually turn on the system fan without directly turning on the heat or AC itself. This is useful if you want to “freshen” up or circulate the air in your home even though the temperature inside is comfortable.
Summary
Perhaps one of smartest and quickest ways to save energy, installing and using a programmable thermostat is one of the best ways to drastically reduce your energy bills in the summer or winter months. There are lots of options and models to choose from, but in the end they all basically do the same thing: automatically regulate your home temperature when you aren’t in your home. By reducing the amount of time your heat or air conditioner has to run just a few hours each day you can give you hundreds of dollars in savings over the course of a single year. If you don’t have a programmable thermostat installed in your home yet, seriously consider

The old joke is, “You can have it done right, on time and within budget. Pick two.”
