Abstract
A microprocessor controlled water temperature control system for a clothes washer. The temperature of incoming mixed hot and cold water is periodically sensed, a cumulative average temperature of the mixed water is compared to a desired temperature value stored in memory. When the comparison results in a temperature difference which exceeds a predetermined error limit, the appropriate hot and/or cold water valves are turned on or off causing the average temperature of the mixed water to change toward the desired temperature value.
