    • A controller for a climate control system has a relative humidity sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity value is used in conjunction with the dry-bulb temperature to generate an enthalpy error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust 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 enthalpy, the enthalpy can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point enthalpy values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.
    • 用于气候控制系统的控制器具有相对湿度传感器以及外壳内的干球温度传感器。 湿度值与干球温度结合使用,以产生焓误差信号,这是干球温度和相对湿度值的函数。 这样可以很好地控制外壳温度和外壳湿度,而不会使气候控制系统发生异常循环。 代替使用直接测量焓的传感器,可以从外壳内的相对湿度和干球温度合成焓。 或者,感测和设定点焓值可以从外壳内的潮湿空气的任何两个热力学特性合成。

    • The present invention describes an apparatus and method for controlling the temperature in a plurality of comfort zones within a house or building. The invention contemplates a series of zone control devices which are selectively opened or closed to allow heating and/or cooling to individual zones. The temperature in each zone is sensed and compared to a preferred setpoint temperature to determine a temperature error for each zone. The respective temperature error signals for each zone are used to determine the zone of greatest thermal error. The zone of greatest thermal error is used to turn the heating/cooling plant on and off. The remaining zone or zones of lesser thermal error have their zone control devices closed or opened, depending upon the temperature error signal for their respective zones. In this manner, all zones are synchronized to the zone of greatest thermal error and to the cycle of the heating/cooling plant.
    • 本发明描述了一种用于控制房屋或建筑物内的多个舒适区域中的温度的装置和方法。 本发明考虑了一系列区域控制装置,其被选择性地打开或关闭以允许对各个区域进行加热和/或冷却。 检测每个区域中的温度并将其与优选的设定点温度进行比较,以确定每个区域的温度误差。 每个区域各自的温度误差信号用于确定最大热误差的区域。 最大热误差区域用于打开和关闭加热/冷却设备。 根据各自区域的温度误差信号,剩余的区域或较小的热误差区域的区域控制装置关闭或打开。 以这种方式,所有区域与最大热误差区域和加热/冷却设备的循环同步。

    • A multiple language user interface system for a thermal comfort controller. The user interface system has a central processing unit coupled to a memory, a language selector and a touch sensitive display unit. The memory can store at least one user interface object and at least one control algorithm. In some embodiments, the user interface system also has a network interface for connecting to the Internet or other network. In some embodiments, the first time the user interface system is powered-up after installation, a first set of user interface objects are displayed on the display unit and the user selects a preferred language. Once a preferred language is chosen, user interface objects can be loaded into the memory and the display unit will display the user interface objects in the preferred language. In some embodiments, control algorithms are loaded into memory.

    • An apparatus to match initiation of temperature changeover settings of a thermostat to a duty cycle of an air temperature conditioning plant without degrading the comfort level of the area of temperature modification. The apparatus prevents short-cycling of either a heating or a cooling system which can occur due to changes in the setpoint temperature. The apparatus operates by determining the length of time of "on" portion and"off" portion of the duty cycle of the air temperature conditioning plant. It then determines the time until the upcoming cycle of the temperature conditioning plant and either advances or delays the temperature changeover until the beginning of the upcoming "on" period or the upcoming "off" period of the upcoming duty cycle, or the last "on" period or the last "off" period of the last duty cycle of the air temperature conditioning plant.
