Abstract:
1. A control system for a water heater having a tank, the control system comprising: a lower sensor disposed to sense a temperature associated with water in a lower portion of the tank of the water heater; an upper sensor disposed to sense a temperature associated with water in an upper portion of the tank; a water heater controller coupled to the lower sensor and the upper sensor, the water heater controller configured to receive the sensed temperatures from the upper and lower sensors, the water heater controller configured to determine a value as a function of a maximum number of a plurality of selectively-illuminable segmented portions included in a display device, the value being determined based at least partially on a first temperature differential equal to a desired set-point temperature less the upper sensor temperature and a second temperature differential equal to the desired set-point temperature less the lower sensor temperature, the water heater controller configured to wirelessly transmit at least one signal indicative of said value and the display device including the plurality of selectively-illuminable segmented portions arranged in a linear array, the display device configured to receive the transmitted at least one signal and to selectively illuminate a number of the segmented portions corresponding to said value as a bar gauge depicting water available at the desired set-point relative to a total water volume of the tank.
