    • An electronic digital programmable wall thermostat system for controlling heating and cooling systems supplying an indoor area or space. The thermostat includes a digital clock, a display for displaying desired parameters of time and temperature and a data entry keyboard for programming the thermostat to maintain desired temperatures during selected time intervals. The heart of the system is a digital processor with memory, which responds to signals from a temperature sensing means which includes an analog to digital converter for controlling the heating and cooling systems in accordance with the sequence programmed therein. The system provides for conservation of energy by automatic system shutdown or setback when the heated or cooled space is unoccupied or during periods when activity in the space is minimal such as during sleeping hours. In a preferred embodiment, a single chip digital processor is used to control the operation of the thermostat system, the keyboard, display and temperature sensing means being selectively scanned from output terminals of the digital processor.
    • 一种用于控制供应室内空间的加热和冷却系统的电子数字可编程壁式恒温器系统。 恒温器包括数字时钟,用于显示期望的时间和温度参数的显示器以及用于编程恒温器以在选定的时间间隔期间维持所需温度的数据输入键盘。 系统的核心是具有存储器的数字处理器,其响应来自温度感测装置的信号,该温度感测装置包括用于根据其中编程的顺序控制加热和冷却系统的模数转换器。 该系统通过自动系统关闭或者当加热或冷却的空间未被占用或在空间中的活动最小的时段(例如在睡眠时间期间)期间提供能量守恒。 在优选实施例中,使用单芯片数字处理器来控制恒温器系统的操作,键盘,显示器和温度感测装置被选择性地从数字处理器的输出端子扫描。
