ABSTRACT:
A bath water control system in which the bath water is selectively supplied a bath or shower outlets, and the water supply is as to both temperature and period of supply. These parameters may be prestored in a memory along with discrete start times whereby a programmed bath will be automatically available at a discrete time or times in the future. As a means of ensuring that water is not accumulated in the tub prior to water temperature rising to a selected value, the tub drain is closed only after input bath water reaches a selected temperature. Further, means are provided for turning off water in the event that water in excess of a selected value appears. Still further, the temperature of water is indicated both digitally and aurally.
