CIRCUIT AND APPARATUS FOR CONTROLLING A WATER SOFTENER

摘要

A novel electronic control circuit which utilizes an improved and greatly simplified arrangement for producing the reference voltage and which includes a probe which includes two pairs of spaced electrodes which are connected in a bridge circuit so that both a reference signal and a control signal is obtained or closing an energizing circuit and latch it until it is time for regeneration and in which the regeneration will occur only at preset times so as to not interfere with normal use.
