Having a home furnace is a huge advantage when the weather turns and it starts to get cold outside. But if you can’t control the heat output of the furnace, then you’re negating the benefits that it provides. The most common interface to the furnace is through a thermostat, which allows you to turn the amount of heat that your furnace produces up or down. Everyone knows what the thermostat does, but how does it work?
The thermostat works by measuring the temperature of the air and adjusting it according to a value set by the user. If you, for example, set the heat to 75, the thermostat will turn on the furnace until the air temperature reaches 75. If the temperature drops below 75, the thermostat will again turn on the furnace to bump the temperature back up. The functioning of the thermostat is critical to maintaining a comfortable temperature in your home, which is why it is important to check and make sure your thermostat is working properly. With temperatures dropping every day, there is no better time than now to check your the functionality of your thermostat.
