A temperature activated shower controller including in combination, a temperature sensor adapted to detect and respond to a pre-determined temperature increase in water supplied to a shower head; a valve adapted to allow or reduce the flow of water to the shower head; programmable microprocessor means responsive to the temperature sensor and adapted to control the operation of the valve, according to a pre-programmed shower duration. In operational use, when turning on the water supply and within a given period of time after the pre-determined temperature rate of change of temperature with respect to time, ie a temperature gradient, is detected, the temperature activated shower controller is initiated and a user can select a shower duration or the microprocessor defaults to a pre-set shower duration after which time the valve moves to the closed position to reduce the flow of water supply to the shower head. |
