Abstract
An adapter for use with a mixing valve, an automatic temperature regulating mixing valve, and a method of providing automatic temperature regulation for a fluid mixing valve are provided. The adapter includes an inlet adapted to attach to an outlet of a mixing valve, and at least one temperature sensing switch positioned to sense the temperature of fluid flowing through the adapter. The thermal sensing switch activates at a predetermined temperature to close its internal contacts. This contacts are wired between the line inputs of the electrically controlled valves governing the flow of fluid into each of the hot and cold fluid inlets of the mixing valve. Both or either a high and low temperature switch may be used. The adapter may also include a flow control element.
