摘要： A furnace for a heating, ventilation, and air conditioning (HVAC) system includes a fuel valve configured to regulate an amount of fuel supplied to a burner of the furnace, a draft inducer blower configured to draw an air flow into the burner, and a controller configured to determine a target operating parameter value of the furnace, determine an air to fuel ratio corresponding to the target operating parameter value, and control operation of the fuel valve, the draft inducer blower, or both based on the air to fuel ratio.
