Abstract
An automatic temperature control for a washing machine or the like may adopt in a first embodiment a single triac switched between a hot-water valve and cold-water valve by mechanical switch elements to provide for a range of temperature control via a microprocessor receiving a temperature command input. In a second embodiment two triacs may be used to permit a range of temperature controls to be effected by voltage signals generated by low-voltage low current switches implemented on an integrated circuit board.
