[ What is claimed is:] [1.] An integrated water treatment control system for a water source, the system including:water treatment elements;first means to circulate water through the water treatment elements;a second means to sense multiple physical characteristics of the circulating water including a means to sense temperature and to adjust the sensed multiple physical characteristics in response to sensed temperature and to determine if the adjusted sensed characteristics are within or outside a given range, and to produce a first signal when any one or more of the adjusted sensed characteristics are outside the given range;third means to treat the circulating water in response to the first signal until the adjusted characteristics sensed to be outside the range return to within the range; and fourth means connected to the second means to detect the failure of a sensor, the fourth means including: fifth means to accept and temporarily store the output of the sensor, sixth means to temporarily disconnect the first signal from the third means and to temporarily apply a forcing voltage to the sensor, and seventh means to measure the recovery of the output of the sensor after removal of the forcing voltage, thereby to detect failure of the sensor and, upon detection of said failure, to generate a sensor failure alarm signal.
