Abstract: A device that includes a pressure sensor that adds dynamic pressure sensing capability to a furnace. In some examples the device may include a relay and other circuitry to replace the single-setpoint pressure switch used to sense the operation of an inducer fan. The pressure sensor may measure the pressure from the inducer fan and send a signal to the other circuitry, such as a microcontroller. The other circuitry may determine when the pressure from the inducer fan reaches a predetermined threshold and allow the main gas valve of the furnace to open. The other circuitry may be configured to set the pressure sensor to a variety of predetermined pressure thresholds, and thereby replace multiple pressure switches. In some examples, the other circuitry may record pressure values received from the pressure sensor over time and provide performance data, as well as other signals or indicators.

Abstract: A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.
