Abstract: A system is disclosed for dispensing a liquid at a desired temperature from a hot liquid pressure line and a cold liquid pressure line to a plurality of liquid outlets such as a bathtub, a sink or the like. The system controls the temperature of the liquid flowing from the plurality of liquid outputs as well as controlling the level of liquid within a container and for maintaining the temperature of the liquid therein. The system includes a liquid recycling system which reduces the amount of liquid discarded during the operation of the system and to converse heat energy. The system is controlled by a novel electronic control which when applied to a water dispensing system is able to control all functions of a bathtub as well as being capable of controlling a sink, a toilet or the complete water system for a residence, a hotel, an industrial or a medical complex or the like.
