Abstract

An automatic temperature control for automatic washers is provided which minimizes the cycling of the water inlet valves to a maximum of two cycles each during the fill process. A predetermined volume of water from a first inlet line is admitted for measuring the temperature and flow rate and then that flow is terminated while a second predetermined volume of water from a second inlet line is admitted for measuring that temperature and flow rate. Then the amount of each of the two inlet streams is calculated so that a final preselected water level will be attained at a preselected temperature.
