Let me make things clear. The beautiful Nest thermostat costs too much and you feel like a pauper. But you are lucky enough that there is an affordable thermostat worth $25 that you can buy on Amazon. This time you won’t need to hire an electrician.

You don’t have to worry because this procedure is much easier than your last exam at school. You will change this dial in half an hour. All you will need is a screwdriver and a flashlight. Don’t doubt me, but after this operation, you will feel like a professional.

In the first place, you have to cut off the power supply of your HVAC system. Find your breaker box and turn off the circuit breaker marked as “Furnace” or “Air Handler”. You definitely shouldn’t skip this step as you may get electrocuted. After your old thermostat gets dark, you are ready to continue.

Remove the faceplate of the old thermostat. There are colorful wires and small screws holding them together. Make sure to make a photo of this mechanism using your phone. Yes, do it right now, while you remember it.

Find the labels of the old thermostat. They are letters like R, W, Y, G. They indicate which functions your system should perform, whether it is heating or cooling. You can see that your new thermostat has labels with the same letters on its base.

Release the screws and remove the wires. Install the new baseplate on the wall using supplied screws. Pass the wires through the hole and secure them under corresponding letters. Connect your “C” wire if you have one. Thus, you will ensure yourself a constant power supply.

Press the faceplate of the new thermostat against the wall until you hear a click. Restore the power supply by turning it back on in your breaker box. If your screen lights up instantly, you did everything correctly. Otherwise, you had some problems with connection and you should double-check it.

Make sure that your thermostat program will increase the temperature when you are awake. It should cool the temperature in the room while you are at school. This simple trick may help you to save a lot of money. Isn’t it great?

The high-tech smart thermostats adapt to your life style, but this one does the opposite – it follows your commands. You saved two hundred dollars using a screwdriver. You can buy a new video game or a large piece of pizza. Enjoy!
