ABSTRACT:
Apparatus for controlling a water heater thermostat for increased efficiency in fuel usage. A mounting bracket is adapted to fit on several different common types of thermostat control boxes and to removably receive a controller housing. A motor in the housing is coupled to a slip ring engaging the thermostat knob to raise and lower the thermostat temperature setting in accordance with sensor actuated circuitry responsive to incoming and outgoing water temperature. The coupling enables the apparatus to accommodate thermostats with different size knobs and rotatable in opposite directions.
