DISPOSITIF DE COMMANDE ELECTRONIQUE DE LA REGENERATION DU LIT DE RESINE D'UN APPAREIL DE CONDITIONNEMENT D'EAU

摘要

A novel electronic control circuit which includes a probe for detecting the conductivity in ion exchange material in a water softener and wherein the probe includes two pairs of spaced electrodes which are connected in a bridge circuit and connected so as to close an energizing circuit and latch it until it is time for regeneration and wherein the regeneration is controlled so that it will occur only at those times which are preset as, for example, during the night when the regeneration will not interfere with normal use of the water supply.
