摘要： A system for detecting stacking and controlling temperature in a water heater. A controller with a connection to a temperature sensor and heating element in a water tank of the heater may be designed to limit stacking and its effects. The controller may use a sensing and calculation technique to detect the stacking. If stacking is detected, then the setpoint for the heater may be lowered so that the outlet water temperature is within a safe limit. If stacking is not detected, then the setpoint may be gradually restored to optimize water heater capacity.

摘要： A method of accommodating an element in a building equipment component. The presence of the element may be detected, and whether the element is required may be determined. The building equipment component may be operated if the element is present and required, or if the element not required. If the element is absent but required, the building equipment component may be stopped. In some instances, the building equipment component may include a required first sensor, and the element may be an optional second sensor.

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： Combustion instability in combustion appliances may be recognized before excessive carbon monoxide may be produced. In some instances, combustion instability may be manifested in flame oscillation, or rather, in oscillations in flame intensity as measured, for example, by a flame sensor. If flame instability is detected, appliance operation may be corrected or terminated.

摘要： A signal generation system for flame ignition and sensing. The ignition signal generation is adaptive for improving flame ignition while eliminating excess energy usage. High voltage signals for flame sensing may also be provided. If more energy or speed is needed for ignition signal generation, then the flame sensing signal generation portion may be disabled to increase the amount of available energy. Adaptation for ignition signal generation may be guided by the results of flame sensing. The flame sensing voltage may be regulated based on the flame current strength. The flame current may be controlled within an optimum range to reduce rod contamination rate and yet provide reliable flame sensing when the rod contamination built up. The adaptation may be algorithmic-based with the facilitation of a microcontroller. The system may provide the high voltage signals from a low voltage power supply, such as that of 24 VAC.

摘要： A self-sustaining control for a heating system, having conventional operational modes and pilot burner assembly, is disclosed. A controller directs operation in accordance with a need-based protocol and monitors the condition of a storage device, which provides system power during the stand-by or off mode under normal conditions. A thermo-electric device is in thermal communication with the pilot burner assembly and powers the system whenever the pilot is lit. Regardless of heat need, the controller directs operation in a pilot-on mode, in lieu of an off mode, whenever the storage device is compromised.

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： An apparatus for and method of monitoring the operation of a stepper motor used to control the main burner valve of a gas appliance by positioning a linear actuator. The gas appliance has a pilot burner. A thermopile thermally coupled to said pilot burner produces an electrical output which powers the stepper motor and a control microprocessor. The control microprocessor monitors the waveforms of potential induced by rotational motion into the unenergized stator coils of the stepper motor. By analyzing the waveforms, the microprocessor can monitor the start time, stop time, direction of the rotational motion, and maximum length of travel of the linear actuator.
