In this tutorial, we learn how to program a thermostat. First, you will need to look up what your home temperature should be at all times, depending on how large it is and what time of the day it is. Once you do this, you will go to your thermostat and figure out how to change the temperature settings for each day of the week. Adjust the temperature to change when you are home and for when you are not going to be home. If you don't have the heat on when you aren't home, this will help you to save money when you are gone!
