摘要： Methods and systems for operating a water heater to limit the effects of stacking in a water heater tank are disclosed. In some cases, the water heater controller may determine a rate of change of the water temperature in the water heater tank. If the rate of change exceeds a threshold value, the controller may adjust the water heater temperature set point downward to help reduce stacking in the water heater. In some cases, the water heater temperature set point may be returned to the original water heater temperature set point when stacking is no longer likely to be of a concern. In one illustrative embodiment, the controller may track the time that the heater of the water heater is in the “on” state, or the time that the heater is in the “off” state, during subsequent heating cycles. The controller may then compare the “on” time or the “off” time to respective recovery threshold times. If the “on” time or the “off” time exceeds its respective recovery threshold time, then the controller may adjust the set point toward the original water heater temperature set point, sometimes in an incremental manner.

摘要： A thermostat which provides a pulse width modulated signal to a gas engine heat pump controller. The thermostat varies the width of the pulse width modulated signal to indicate the load required to heat or cool the room. The thermostat provides an initial idle time for the gas engine heat pump. The thermostat further steps the gas engine heat pump down from high speed operation and idles the engine prior to shutting the engine off.

摘要： Methods and apparatus for controlling the cooling set point value of a climate control system are provided. In one illustrative embodiment, a humidity error is determined as a function of the actual humidity in the inside space and a humidity set point value. The cooling set point value is then adjusted by a cooling offset that is a function of the humidity error. Under humid conditions, and when insufficient dehumidification occurs during a normal cooling cycle, lowering the cooling set point may provide further dehumidification, which may improve comfort in the inside space. Under less humid conditions, and when the humidity level in the inside space is already below the humidity set point value, increasing the cooling set point value may lower the energy usage of the climate control system while still providing comfort.
摘要翻译：提供了一种用于控制气候控制系统的冷却设定值的方法和装置。在一个说明性实施例中，湿度误差被确定为内部空间中的实际湿度和湿度设定值的函数。然后通过作为湿度误差的函数的冷却偏移来调整冷却设定值。在潮湿条件下，并且在正常冷却循环期间发生不充分的除湿时，降低冷却设定点可以提供进一步的除湿，这可以提高内部空间的舒适度。在较不潮湿的条件下，当内部空间的湿度水平已经低于湿度设定值时，增加冷却设定值可能会降低气候控制系统的能源消耗，同时仍然提供舒适度。

摘要： A method of communicating between a plurality of devices in a controller area network is disclosed. The method includes a first device transmitting a first message over the network, a second device comparing a first value in the first message with a second value, and a third device responding to messages it receives over the network. The method may involve a number of producer devices and a consumer device. The consumer device responds to messages sent as instance zero. The method may involve a number of producer devices, an intermediate consumer and a consumer device. The producer devices send their messages as instances other than zero. The intermediate consumer receives the messages from the producer devices, compares them, and sends messages as instance zero to the consumer device. The producer devices may be thermostats, actuators, sensors, etc. The consumer device may be a furnace, an air conditioner, etc.

摘要： An interface circuit is designed to connect a first logic circuit such as a microcontroller with a second similar microcontroller using three wires and allowing for simultaneous transfer of data from each of the microcontrollers to the other. A transmitter element in each interface circuit has a bias resistor which cooperates with a pull-up resistor in the other interface circuit to provide an indication for one of the logic circuits when the other of the logic circuits and its associated interface circuit loses power or when one of the three connecting wires is disconnected.

摘要： A printed wiring board connector which mechanically supports the board. A connector base has legs which extend away from ends of the base and terminate in stakes which penetrate the board for attachment and electrical connection. Walls extend from the base, arch over the base, and terminate above the base. A conductive protrusion extending from a mounted electrical device is secured between the free ends of the walls and the base providing both support of the printed wiring board and electrical connection.
