摘要： A fault detection system and method for a warm air furnace is provided. A sensing circuit connected to an AC power source measures a level of current consumption during several points in the warm air furnace operating sequence. The measured level of current consumption is compared with an expected value. If the measured level exceeds the expected level by a threshold amount, a fault in the warm air furnace may be detected. An indication of at least one warm air furnace component that is most likely to have caused the fault may be provided.

摘要： A solid-state fail safe gas valve system in which first and second gas valves are arranged in series in a gas passageway, the valves being actuatable by first and second solenoid operators respectively, the second operator requiring a voltage greater than the operating voltage supplied to the valve system to achieve actuation. The operators are separately energized through microprocessor controlled switches so that a capacitor connected across the second operator and its switch is pumped to a voltage above the supplied voltage by voltage induced by interrupted energization of the first operator.

摘要： An ignition circuit and method for a hot surface ignitor. The ignition process and apparatus enforces a short warm-up period for the hot surface ignitor where approximately half power is supplied at start-up to the ignitor until the ignitor warms to a point where its impedance is increased. By warming the ignitor gradually, the system power supply is not pulled down to a level which may cause malfunction of other electronics connected to the same supply. Further, the voltage level to the ignitor is controlled so that service life of the ignitor is extended.

摘要： A warm air furnace system has a valve for controlling the flow of fuel, and a mixing component for receiving fuel from the valve and mixing the fuel with air to form an air-fuel premix. The warm air furnace system also has a burner assembly for receiving the air-fuel premix from the mixer, and an inducer for pulling the air-fuel premix through the burner assembly. The air-fuel premix drawn from the burner assembly is ignited into a flame by an ignition element. The flame transfers heat to a heat exchanger in communication with and positioned between the burner assembly and the inducer. The heat exchanger, in turn, transfers heat to air being passed over the heat exchanger by a circulation fan. The heated air passed over the heat exchanger then provides heat to a user of the furnace.

摘要： A burner assembly for use in a warm air furnace. The burner assembly has a cooling air box for receiving air and a premix burner for receiving air-fuel premix positioned within and spaced apart from the cooling air box. The burner assembly also has a burner face assembly defining a front end of the premix burner. The burner face assembly includes a first plate positioned on top of a second plate, and a third plate positioned underneath the second plate. Each plate of the burner face assembly has a plurality of aligned burner openings.

摘要： Appliance control with ground reference compensation is provided. Ground reference compensation can be desirable when a device or component of an appliance is powered by a higher power source, and is controlled by a controller that is powered by a lower power source. In such a situation, a voltage difference can develop between the ground references of the higher and lower power sources, which can affect accurate control of the device or component. In some cases, a measure related to the voltage difference between the ground references is first determined, and then the power/voltage that is ultimately delivered to the device or component is adjusted or compensated based, at least in part, on the determined difference.

摘要： A vibration isolating motor mount has a U-shaped mount having the end of the legs of the "U" arranged at right angles thereto to form mounting ears. One leg end ear is arranged to be connected to a motor support plate which is perpendicular to the plane of the legs of the U-shaped mount. The plate is, in turn, attached to a first end of the motor with the plane of the plate being perpendicular to the axis of rotation of the motor. The end ear of the other leg is arranged to be connected to a motor support frame having the plane of the frame also perpendicular to the axis of rotation of the motor. The other end ear may include a vibration absorbing bushing isolating the respective mounting ear while surrounding a mounting pin attached to the support frame. The plane of the legs of the U-shaped mount is arranged to be co-planar with the axis of rotation of the motor. A plurality of the motor mount may be equally spaced on the periphery of the motor support place to provide added support for the motor. A motor shaft is arranged to extend from a second end of the motor to provide an attaching element for a motor driven device, e.g., a pulley, fan, etc.

摘要： A controller for a climate control system has a humidity (wet-bulb or dew point) temperature sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity temperature value is used in connection with the dry-bulb temperature to generate a single error signal which is a function of both the dry-bulb and the humidity temperature values. This permits control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the humidity temperature, the humidity temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure.
