What is a thermostat & how does it work?
It’s the main control point that determines when and how much heat will be delivered by the furnace. At the most basic level, thermostats are simply temperature-sensitive switches but they have become sophisticated with more features.

What is a furnace thermostat?
The furnace thermostat is the nerve center of your home heating system. It’s the main control point that determines when and how much heat will be delivered by the furnace. At the most basic level, thermostats are simply temperature-sensitive switches but they have become sophisticated with more features.
What is a manual thermostat?
Manual thermostats can be analog or digital. Digital versions feature large screens for easy temperature readings. They are typically found in older homes. They are more affordable with simple controls. They offer limited energy savings and comfort, but can work efficiently if you’re diligent about adjusting settings as the temperature changes.
Do thermostats have digital controls?
Digital controls can be used in both line-voltage and low-voltage thermostats; the presence of digital controls does not always mean the thermostat is a low-voltage model. The older-style mechanical/analog thermostats work by making use of the physical principle by which metals and gases expand or contract as the temperature changes.
