ABSTRACT:
A water heater control for an electric water heater operates according to at least one fixed hardware and/or software temperature limit and a variable software temperature limit. The control monitors a temperature of water in a tank of the electric water heater to determine if the temperature exceeds the fixed hardware and/or software temperature limit. If the temperature exceeds the fixed temperature limit, the control turns off one or more heating elements of the electric water heater. The variable software temperature limit is indicative of a desired user temperature and an offset temperature. If the temperature exceeds the variable software temperature limit, the control turns off the one or more heating elements.
