Abstract
A control system for an electric water heater having an upper heating element and a lower heating element is disclosed. The control system includes a control module that controls operation of the electric water heater by selectively toggling the upper and lower heating elements between an ON state and an OFF state and a consumer interface module that allows a consumer to input a set point temperature and select an energy savings mode for the electric water heater. The control module regularly monitors hot water usage and adjusts the set point temperature by a predetermined setback amount until a capacity of the water heater matches consumer usage.
