    • In an electronic thermostatic circuit, a resistive bridge network is employed to sense the level of the ambient temperature. The bridge includes three legs having fixed resistors and one leg having a temperature sensitive resistor as well as a serially connected adjustable potentiometer. The adjustable potentiometer is adjustable to provide a selected set point for the operation of the thermostat within a given range of temperatures. The adjustable potentiometer is provided with a shaft to which an adjusting knob having a pointer thereon is secured by means of a slip fastener. Calibration of the assembly is accomplished by turning the knob with its pointer pointed in a preferred direction then holding the knob while adjusting the shaft and the associated potentiometer until the bridge output corresponds with the value indicated by knob pointer.
    • 在电子恒温电路中,使用电阻桥接网络来感测环境温度的水平。 该桥包括具有固定电阻器的三条腿和具有温度敏感电阻器的一条腿以及串联连接的可调节电位器。 可调节的电位计是可调节的,为给定温度范围内的恒温器运行提供一个选定的设定点。 可调节电位计设有一个轴,通过滑动紧固件固定有一个带有指针的调节旋钮。 通过旋转旋钮将指针指向一个优选的方向,然后在调节轴和相关的电位器的同时按住旋钮,直到桥输出对应于旋钮指针所指示的值,来完成组件的校准。

    • A room thermostat having an electronic circuit board mounted in a cover and attached to a base member. A space is provided between the back side of the circuit board and the front of the thermostat cover whereby air can pass along the back side of the circuit board to "air wash" for removing heat which is generated by the electrical components mounted on the front side of the circuit board. The front side of the circuit board has a cover over the electrical components for shielding the heat from the components from a temperature responsive element. The temperature responsive element is mounted in a channel provided by the thermostat cover and shield to allow air flow past the temperature responsive means through a channel which includes the space between the thermostat cover and the base.

    • A clock thermostat apparatus adapted for controlling temperature conditioning apparatus maintains a normal control temperature in a space and during certain selected time periods deviating from the normal temperature control by resetting the normal temperature control to some lower temperature for comfort and energy conservation. The clock thermostat apparatus has a manual temperature selection means and a manual temperature deviation selection means for selecting the normal control temperature and the amount of reset or deviation during the selected time period. A connection means is provided between the temperature selecting means and the temperature deviation selection means to turn the temperature deviation selection means to a lower value when the temperature selection means is moved to some predetermined low temperature. When the normal control temperature selection is reduced by the temperature selection means, the temperature maintained is not reset to a low temperature during a setback time period which might be so low that freezing of water pipes would result in the space wherein the temperature is being controlled.
    • 适于控制温度调节装置的时钟恒温器装置通过将正常温度控制重置为一些更低的温度来舒适和节能,保持空间中的正常控制温度和偏离常温控制的某些选定时间段。 时钟恒温装置具有手动温度选择装置和手动温度偏差选择装置,用于在所选择的时间段内选择正常控制温度和复位或偏移量。 在温度选择装置和温度偏差选择装置之间设置一个连接装置,当温度选择装置移动到某一预定的低温时,将温度偏差选择装置转到较低的值。 当通过温度选择装置降低正常控制温度选择时,在遏制时间段期间保持的温度不会被重置为低温,这可能太低,使得水管的冻结将导致其中控制温度的空间 。
