Thermostat Wiring Explained - Electrical-online
The line voltage feeding the furnace (to operate the fan blower motor) is transformed down to a safer level of 24 volts (the gas control valve needs 24 volts to open), and after making a series loop through at least one safety device (the most basic and mandatory one is an over-temperature shut down), the power goes up to the thermostat, and
Fan (machine) - Wikipedia
A fan is a powered machine used to create a flow of air.A fan consists of a rotating arrangement of vanes or blades, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runnerlly, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades.
