    • A regeneration control and timer system for one or two water softening or conditioning units to provide for regeneration of the softening material when it has become exhausted, with each water softening unit containing a sensor for indicating the stage of exhaustion of the material and actuating a timer for initiating a regeneration cycle. A timer clock is also present for utilization if the sensor is inoperable and the control contains a shiftable lever and a switch to change from sensor to clock operation. Also, the control system provides for duplexing of the timers and sensors of two water softeners using only a pair of connecting wires so that only one of the two softeners will be regenerated at a time even though both softeners reach the point of exhaustion at substantially the same time.
    • 一种用于一个或两个水软化或调节单元的再生控制和定时器系统,用于当软化材料已经排空时提供软化材料的再生,每个水软化单元包含用于指示材料耗尽阶段的传感器并致动定时器 用于启动再生循环​​。 如果传感器不可操作,并且控制器包含可变换杆和从传感器切换到时钟操作的开关,定时器时钟也可用于利用。 此外,控制系统仅使用一对连接线来提供两个水软化器的定时器和传感器的双工,使得两个软化器中的仅一个将一次再生,即使两个软化剂达到基本上为 同时。
