Zusammenfassung: | A water temperature sensing and control apparatus for automatic washers having a thermistor mounted within a projection that extends into a water inlet stream in a water inlet housing. A thermally semiconductive potting material encases the thermistor to provide a delayed response of the sensor to changes in water inlet temperature. A control circuit connected to the thermistor includes a pair of comparators for controlling hot and cold water inlet valves in response to the sensed temperature to achieve one of a plurality of selectable wash bath temperatures. |
