A retrofit automatic temperature controlling apparatus and kit is attached to a prior art steam-cold water mixing valve assembly to produce mixed cold water and steam as hot water at a controlled temperature. An adjustment screw is added to the prior art valve assembly to limit the displacement of a steam poppet valve which is opened by a retrofitted piston. Cold water is redirected to a retrofit temperature control assembly having a mixing chamber for receiving the cold water. A water and steam receiving conduit terminates in the mixing chamber and has fluid isolated sections for receiving steam and cold water with a sleeve valve member for selectively coupling the steam and cold water sections to the mixing chamber. The sleeve valve member is operated by a temperature sensing device in the outlet hot water chamber. A disc member separates the mixing chamber and outlet hot water camber with small passages which promote mixing. |
