Abstract:
A control for a water heater is provided that comprises a pressure switch for sensing a predetermined level of airflow sufficient for maintaining proper burner operation, and a temperature sensing means for sensing the temperature of the water in the tank. The control further comprises a processor for controlling the operation of the burner to maintain the water temperature above a predetermined value. When the processor receives a signal from the pressure switch or temperature switch indicating a malfunction, the processor shuts down the burner and subsequently attempts to restart the burner. The processor will lock-out further burner operation after a predetermined number of consecutive shut downs occurs, and will communicate any malfunction information to a remote display device.
