ABSTRACT:
A water heater has a modular control system. The water heater comprises a tank, a heating element, a first controller, and a second controller. The heating element is coupled to the tank. The first controller is mounted on the tank and has a first communication port. The second controller has a second communication port communicatively coupled to the first communication port of the first controller. The first controller is configured to control the heating element in accordance with a first algorithm in an absence of the second controller, and the second controller is configured to control the heating element in accordance with a second algorithm.
