A method of setting an exclusive controller for a water heater, wherein a plurality of controllers are provided for a user to operate to control a water heater, the method comprising the steps of: a) providing each controller an identification code, pre-storing the identification codes of the controllers in a processor of a water heater, and arranging the processor to identify each controller based on its identification code; b) inputting a command through a controller, and sending the command to the processor of the water heater, wherein the command includes the identification code of the controller; c) making a recording that the controller is an exclusive controller when the identification code in the command is identical to the identification code in the processor, and executing the command to control the water heater; d) receiving a command from any one of the controllers, and executing the command to control the water heater when the identification code of the command is identical to the identification code of the exclusive controller, or rejecting the command when the identification code of the command is not identical to the identification code of the exclusive controller; e) repeating the step d until the recording of the exclusive controller is canceled; and f) rejecting the command if its identification code does not match any identification codes pre-stored in the processor.
