What to Look for When Buying a Programmable Thermostat

Understand your Heating/Cooling system requirements.

Make sure that the thermostat is compatible with your system. The most common types are central heat or central heat with air conditioning.  These systems can control gas, electric, or oil systems.  Also know whether your system is 1-stage or 2 stage heating and cooling.

Other system types include radiant floor, electric baseboard, heat pump, fireplace, and floor/wall furnace.

Once you know what type of system you have, then you can review the thermostat features to find which will best meet your needs.

Why should I consider a Programmable thermostat?

Adding a programmable thermostat is a fairly quick and easy project that you can do on your own. A thermostat that you can program to your schedule and temperature needs, will help provide you with a more comfortable and energy efficient home. If you follow the recommended Energy Star settings, you will use less energy and save money on your heating and cooling bills. And when temperature changes are programmed, you won’t be at work thinking, “Oh, I forgot to turn down the heat when I left, and I’m wasting money!”

What kind of programming do you need?

Consider what you and your family do each day, when do you get up, leave for work, whether you stay home or go out on the weekends. Do you need to program a different schedule for every day of the week or is one schedule for the weekdays and one schedule for the weekend enough?

External Design

Consider how it will look in your home. What color is it? Can you change the color of the screen? What kind and size of viewing screen do you need? Is it easy to read, does it have a backlit screen, can you turn the back light off? Does the screen have touch capability? Are the buttons easy to read and use?

Extra Features

Programmable thermostats come packed with extra features that can increase comfort and save you time and money. These include:

  • A vacation feature that allows you to set a special schedule for when you are going to be gone a long time, like on a vacation.
  • Special Alerts can include reminders to change the thermostat  batteries or your systems air filters, or alert you to heating and cooling system malfunctions.
  • Intelligent recovery means that the thermostat can learn how quickly the system needs to come back on to achieve your desired temperature by the set time.
  • Back-up memory retains your set programming in the event of a power outage, keeping you from having to re-enter everything.
  • WiFi capability for setting up a smart home.

Warranty and Support

Make sure your thermostat comes with a manufacturer’s warranty in case it malfunctions. It should also come with a manual that shows you how to set up and operate the unit.

Frequently Asked Questions

Can you tell me how to install a programmable thermostat?

The model you purchase should have complete instructions. It’s different for new construction and replacement. Here’s an overview of each. 


  1. Loosen the fastening screws, and gently pull the thermostat off the wall.
  2. Take a picture of the wires connected to the terminals.
  3. Loosen the wires, and remove the thermostat.
  4. Hook up the wires to the new thermostat using your picture to guide you, so that the same colored wires go to the terminals with the same code. 

Our Thermostat Wiring Guide has more details including this diagram that shows you what we are talking about:

thermostat wiring colors to labels

This video shows another method using stickers that come with your new thermostat. 

New construction (no existing thermostat): Simply follow the wiring diagram sent with the thermostat. It will tell you what color wire to connect to each terminal. 

What does 7 Day, 5-2 Day, and 5-1-1 Day scheduling or programming  mean?

7 Day means that you can program a different heating or cooling schedule for every day of the week. 5-2 means that you can program one schedule for Monday through Friday and a different schedule for Saturday and Sunday, and 5-1-1 means that you can program one schedule for Monday through Friday and a different schedule for each day of the weekend.

If you typically work during the week, a 5-2 might work for you, but if you have weekend activities, a 5-1-1 might be best. If your schedule changes daily, you might prefer a thermostat with full 7 day scheduling.

Consider what you and your family do each day, when do you get up, leave for work, whether you stay home or go out on the weekends. Do you need to program a different schedule for every day of the week or is one schedule for the weekdays and one schedule for the weekend enough?

Why should I consider a Programmable thermostat?

Adding a programmable thermostat is a fairly quick and easy project that you can do on your own. A thermostat that you can program to your schedule and temperature needs will help provide you with a more comfortable and energy-efficient home. If you follow the recommended Energy Star settings, you will use less energy and save money on your heating and cooling bills.

How can a programmable thermostat save money?

With a programmable thermostat you can pre-set the thermostat to follow your schedule throughout the day. And when temperature changes are programmed, you won’t be at work thinking, “Oh, I forgot to turn down the heat when I left, and I’m wasting money!” You can create a schedule that fits your family’s routine. And most programmable thermostats allow for 4 periods per day, so, for instance, you could keep the heat or air conditioning higher in the morning and evening when you are home, and lower in the day when you’re away and overnight while you’re sleeping.

Programming for these lower heating or cooling periods allows the unit to run less and therefore use less energy, saving you money. For every degree that you keep the heating or cooling down, will save you about 2% on your utility bill.

How can a programmable thermostat save you time?

A programmable thermostat will save you time because you don’t have to spend time throughout the day adjusting it to your desired temperature.

Do programmable thermostats allow you to override the settings without pre-programming the unit?

Yes, you can temporarily override your set schedule. After a set time, the thermostat will automatically return to the programmed schedule. Your manual will have instructions on overriding as well as, how long it will take for the thermostat to return to the programmed schedule.

What is Staged Heating?

2-stage heating means that your furnace has 2 levels of heat output – a higher level for cold days and a lower level for mild days. Because the low level is enough to meet heating demands 80% of the time, a 2-stage unit runs for longer times and maintains a more even temperature, eliminating highs and lows. The furnace will operate most of the time at the lower level and burn less fuel. The same idea applies to 2-stage air conditioning.

Where in your home is the best place to install a thermostat?

The best place to install a thermostat is on an interior wall, away from all exterior doors, windows, heating and cooling vents, and out of direct sunlight. This will help keep the actual temperature of your home true to the thermostat setting.

What is Energy Star?

Energy Star is a trusted, government backed, set of criteria for energy efficiency, helping us all save money and protect the environment through energy efficient products and practices.

Many programmable thermostats come with pre-set Energy Star recommended settings designed to reduce energy use. Using the Energy Star recommended thermostat setting can reduce your energy bills and save you money.

Is a WiFi thermostat worth the money?

If you get a good one, it can save you money and pay for itself in a few years. How? It allows you to control the system from anywhere, obviously, and that can reduce waste. For example, let’s say it’s a hot summer day, and the thermostat setting is scheduled to change from 80 degrees to 75 degrees at 5pm because you normally get home at 6pm. However, if you decide to go to dinner with friends and don’t expect to be home till 9pm, you can use your phone and the thermostat app to change the setting so the thermostat set point doesn’t change until 8pm.
