Abstract
A device for controlling a temperature of a fluid includes a plurality of valve assemblies, each coupled to a cold fluid supply, a hot fluid supply, and an outlet line. An orifice is coupled to each outlet line and to a combined outlet line that is common to all orifices. Each of the orifices has a proportionally different flow area. Hot and cold fluid supply temperature sensing elements are coupled to supplies. A controller is coupled to the hot and cold fluid supply temperature sensing elements and the plurality of valve assemblies. The controller selectively couples one of the cold fluid supply or the hot fluid supply to the outlet line for each of the plurality of valve assemblies responsive to the cold fluid supply temperature sensing element, the hot fluid supply temperature sensing element, and a desired temperature in the combined outlet line.
