Abstract
A water heater having a modular control system. The water heater includes a tank, a heating element, a first controller, and a second controller. The heating element is coupled to the tank. The first controller is supported by the tank and includes a housing, a first communication port, a processor, and a first memory storing executable instructions that are executed by the processor. The first controller determines whether the first controller is connected to the second controller through the communication port. The first controller controls an operation of the water heater according to a first algorithm when the first controller is not connected to the second controller. The operation of the water heater is controlled based on an algorithm stored on the second controller when the first controller is connected to the second controller.
