ABSTRACT:
A forced-air HVAC system has an induction motor that drives its fan or blower. The motor is controlled by a circuit that causes the speed of the fan or blower to vary continuously whenever the HVAC system operates. The controller circuit includes temperature sensors that continuously monitor the temperature of the air the system is delivering. These sensors signal the controller circuit to vary the speed of the fan or blower motor in order to maintain at an optimal level the air temperature in the spaces heated or cooled by the system.
