ABSTRACT:
A fully integrated electronic appliance controller for controlling the operation of a appliance (e.g., a gas-fired water heater or boiler). The controller includes an integrated intelligent control system; enhanced safety features including an igniter current proving circuit, a flame detection circuit, a safety limit string and an energy cut-out (ECO) control; an intelligent user interface including a display unit and a communications system; and an adaptive control feature. According to a preferred embodiment of the present invention, the controller is adapted to receive as many as four temperature probes (e.g., thermistors). The first probe senses the water temperature at the outlet of a water heater, the second probe senses the water temperature at the inlet of the water heater, the optional third probe senses the temperature at a first location in an associated remote water storage tank, and the optional fourth probe senses the temperature at a second location in the associated remote water storage tank.
