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 modulating furnace having a variable rate burner and a controller is operated at a first burner firing rate for a first period of time, and a higher burner firing rate once the first period of time has expired. In some instances, the burner may be operated only while the controller is receiving a call for heat from a thermostat or the like.

摘要： A furnace controller for a modulating furnace that helps provide a balance between energy efficiency and occupant comfort across various burner firing rates and/or across various circulating blower speeds. In some cases, the furnace controller can be configured to permit a user to customize operation of the furnace in accordance with their particular needs and/or desires with respect to efficiency and comfort. A selection may be made between an energy efficiency setting and a user comfort setting. Then, a plenum parameter such as a discharge air temperature (DAT) or discharge air flow (DAF) may be regulated in accordance with the selected setting.

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.
