The thermostat in your home is one of the key parts to operating your heating and air conditioning unit to your preference. A thermostat is an automatic device that regulates temperature in an enclosed area by controlling heating or refrigerating systems. It is commonly connected to one of these systems, turning it on or off in order to maintain a predetermined temperature. Its operating principle is because one of its components expands or contracts significantly during a temperature change. This expansion or contraction actuates a control on a furnace, cooling system, or piece of machinery.

A mechanical non-programming thermostat is just that, you have to manually change the temperature. You do not have any sort of screen with a mechanical non programming thermostat. These thermostats turn on when you switch them on and turn off when you switch them off, the temperature adjusts when you manually adjust the temperature lever. These thermostats were once the most common type of thermostat, but they are being phased out because they contain a small vial of mercury in them. A digital non-programming thermostat has a digital display but just as the mechanical non-programming thermostat you have to manually change the temperature, and manually turn the system off and on. These thermostats are now among the most common type of thermostat.

There are several different types of programmable thermostats. A programmable thermostat does not require any manual adjustments to the thermostat every time there is a temperature change.  Starting with the 7 day programming thermostat, these thermostats allow you to have a different setting for each day of the week, and at several different setting s throughout the day. A 5-1-1 programmable thermostat can be programmed for a different setting for the weekdays and for Saturday and Sunday. This programmable thermostat allows for different setting throughout the days just as the 7 day programmable thermostat. The 5-2 programmable thermostat has the option to program for up to four different periods throughout the weekdays and weekends. Lastly the 1 week programmable thermostat has the ability have one programmable setting for the entire week; this thermostat is the most simple from the programmable thermostat category.

A learning thermostat does not require any programming, a learning thermostat  does just that it learns what temperature you set it on when you come home from work, or when wake up in the morning, etc.  A learning thermostat is perfect for homeowners that have consistency in their schedule, if you do not have consistency, and then the thermostat will never learn any routine behavior.
