How to Set a Thermostat
Visit an air conditioning and heating product supplier such as Honeywell and look up thermostats for directions on how to install a new thermostat If you are a do-it-yourself type, otherwise hire a professional.
Set the program to conserve energy during the day when no one is home and while you are sleeping. For maximum benefits you should aim setting your thermostat at 68 to 70 degrees in the heating season, and 78 to 80 degrees during the cooling season.
Determine the thermostat you pick by how often you are at home and what best fits your schedule. There are many different thermostats but, generally, they all come with at least four pre-programmed settings and they maintain those setting within two degrees. 7 day models will work best for you if your schedule changes daily. 5+2 day models are good for work week schedules and 5-1-1 models work well if you keep the same weekday schedule but different schedules on your days off.
Override the program without changing it if you need to change the temperature. Try not to do that too often, the override will decrease the efficiency you have programmed the thermostat for. The thermostat will change back to the preprogrammed temperature at the next program interval.
Change the batteries yearly if your thermostat requires batteries. A good rule of thumb is when daylight savings time occurs in the fall. Include the batteries for smoke alarms at the same time.
Find out where the air flows on each thermostat and program them accordingly if your home has more than one thermostat.
Check to see if your emergency indicator light is on occasionally. If you live in a very cold area, and your temperature drops below 32 degrees, your thermostat might have an indicator light that will tell you the emergency back-up is on. It might also come on when there is a problem with your heat pump.
Adjust your thermostat up and down when you come home or leave and when you go to sleep if you are using a manual thermostat.
