    • An electronic control circuit for use with a heater, a fan, a humidifier, a cooking apparatus, or any device utilizing a power mode switch and a condition sensor, and time-automated switching of modes of operation. The circuit includes a single control switch to manually set power output, to set a value for automatically comparing and responding to a sensed condition, and to set a time-automated sequence of operational modes. The circuit includes a microprocessor, preferably an application-specific integrated circuit, to provide circuit logic. The single control switch, preferably a push-button switch, selects a mode of operation. The circuit includes a thermistor or humidity sensor. The unit responds to the sensed condition, in accordance with the temperature/humidity value set by the control switch. The unit bypasses sensor operation in manual mode. In timed mode, a manual or automatic mode operates for selected time, followed by an automatic mode or powering off.
    • 一种与加热器,风扇,加湿器,烹饪设备或利用电源模式开关和状态传感器的任何设备一起使用的电子控制电路,以及操作模式的时间自动切换。 该电路包括单个控制开关,用于手动设置功率输出,设置用于自动比较和响应感测状况的值,并设置时间自动化的操作模式序列。 电路包括微处理器,优选地是专用集成电路,以提供电路逻辑。 单个控制开关,优选地是按钮开关,选择操作模式。 该电路包括一个热敏电阻或湿度传感器。 根据控制开关设置的温度/湿度值,本机响应感测条件。 本机在手动模式下绕过传感器操作。 在定时模式下,手动或自动模式在选定时间内运行,然后进行自动模式或关机。
