INTEGRATED APPLIANCE CONTROL SYSTEM

摘要

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 curren t proving circuit, a flame detection circuit, a safety limit string and an energy cut-out (ECO) contr ol; an intelligent user interface including a display unit and a communications system; and an adap tive control feature. According to a preferred embodiment of the present invention, the contr oller is adapted to receive as many as four temperature probes (e.g., thermistors). The first pro be senses the water temperature at the outlet of a water heater, the second probe senses the w ater temperature at the inlet of the water heater, the optional third probe senses the temperatur e at a first locatiopn 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.
