ABSTRACT:
A temperature and flow controller for a bath tub or shower is disclosed. The device includes a panel that replaces or surrounds the standard bath tub water valves. Within the panel is a control assembly in communication with temperature sensors in the shower head and the bath tub faucet as well as control valves on the hot and cold water supply lines. The temperature sensors are immediately downstream from a unique, two stage mixing chamber having a rotatable impeller in a first section and a helically grooved inner surface in a second section to thoroughly mix hot and cold water therein. The controller also includes means for enabling water flow at a preset time of day, for a predetermined duration or to deliver a predetermined volume of water.
