摘要： A furnace includes a combustion blower and one or more pressure switches. In some cases, the one or more pressure switches may be used to calculate one or more operating points for the combustion blower. Additional operating points may be calculated by interpolation and/or extrapolation, as appropriate. The furnace may temporarily alter these operating points as necessary to keep the furnace safely operating in response to minor and/or transient changes in the operating conditions of the furnace.

摘要： A low cost flame sensing system having at last one floating point. For instance, the system may have two grounds. There may be a flame sensing rod for detecting a flame which has a model circuit which appears upon the existence of the flame proximate to the sensing rod. The sensing rod may function without an explicit or dedicated excitation source connected to it. There may be diagnostics in the system for detecting leakage or shorts of the sensing rod to ground. Also, the system may have AC grounding phase detection.

摘要： Methods and systems for operating a fuel fired appliance that may include an optional hardware component such as a damper are disclosed. In some cases, the presence of the optional hardware component is detected, and it is determined whether the optional hardware component is required for future operation of the fuel fired appliance. The fuel fired appliance may be operated normally if the optional hardware component is present and required, or, in some cases, if the optional hardware component is determined to be not required. If the optional hardware component is absent but required, normal operation of the fuel fired appliance may be stopped.

摘要： A water heater performance monitoring device for monitoring whether a water heater is functioning optimally or whether it requires service. The device uses maximum heating rates taken from a plurality of measured heating rates to determine if the performance of the water heater has degraded from a threshold performance level. A water heater performance monitoring device can reduce the number of false alarms that occur regarding the need for water heater service by filtering out temporary factors, lasting less than a time cycle, which affect heating rate of water in the water heater. This can save users time and money by reducing unnecessary water heater inspections.

摘要： A flame rod drive signal generator and system for producing a flame rod drive signal for a flame rod of a combustion system. In one illustrative embodiment, the flame rod drive signal generator may include a voltage source, an input signal having a frequency, an LC oscillator and a drive mechanism. The drive mechanism may be powered by the voltage source, and may have an output coupled to the LC oscillator. The drive mechanism may receive the input signal, and produces a current in the LC oscillator that has a frequency that is related to the frequency of the input signal. The LC oscillator may then provide a flame rod drive signal to a flame rod that has an amplitude that is larger than the amplitude of the voltage source. In some cases, a controller may monitor the amplitude of the flame rod drive signal and adjust the frequency, duty cycle, or both, of the input signal to achieve a desired amplitude of the flame rod drive signal. Alternatively, or in addition, the controller may monitor an ionization current produced by the flame rod when the flame rod is subject to a flame.

摘要： A method and apparatus for determining a health status of a water heating device is disclosed. The water heating device may have a controller that incorporates logic to regulate the heater responsive to water temperatures detected at different areas within the water heating device by first and second sensors. Unfortunately, the first and second sensors may fail. To detect fault conditions or otherwise determine the heath status of the water heating device, a logic unit in the controller may perform a test on the first and/or second sensors so as to provide a test output. The logic unit may also determine whether the test output satisfies one or more predetermined thresholds. These predetermined thresholds may be indicative of a properly-functioning sensor. When the test output does not satisfy the at least one predetermined threshold, the logic unit may then set a fault condition indicative of improperly functioning sensors.

摘要： A system for operating a flame sensing device to obtain readings of increased accuracy without degrading the life of the sensor. There may be levels of a flame requiring a precise measurement. One improvement of accuracy uses higher voltage on the sensor, but this degrades the sensor and thus shortens it life. Further improvement may be achieved by limiting the time that the sensor is operated at a higher voltage. Readings, as if the sensor were operated at a higher voltage, may be inferred from actual readings of the sensor operated at a lower voltage.

摘要： A flame sensing system having a flame rod, a signal generator, a signal measurement circuit, and a controller, where the frequency and/or amplitude of the excitation signal may be variable. The signal measurement circuit may include a bias circuitry that references the flame signal to a voltage, a capacitor that varies the filtration, an AC coupling capacitor, a current limiting resistor, and a low-pass filter. The system may determine the flame-sensing rod contamination, the stray capacitance of the flame sensing system, and compensate for stray capacitance in the flame sensing system. The flame model may include a circuit that simulates a flame in the presence of the sensing rod, and another circuit that simulates a contact surface between the flame and the sensing rod.
