Abstract
A system and method for controlling a heating and ventilating system is provided. The method includes determining a demand for heat and creating an air flow. In addition, the method includes sensing an outlet discharge temperature of the air flow and increasing the temperature of the air flow to a selected value. Generally, the method further includes increasing the air flow velocity, while maintaining the discharge temperature of the air flow to the selected value. The system for controlling a heating and ventilating system includes an input for receiving a demand signal and a heater control circuitry for controlling the heat output of a heat source. In addition, the system includes ventilation control circuitry for controlling the flow of an air source and an outlet air temperature sensor. Finally, the system preferably includes a microcontroller for controlling the heat output and the flow of the air source.
