Abstract
A function indicator system for displaying the control settings related to functions and features of an electric fireplace. The function indicator system can feature a function indicator module, a controller communicatively connected to the function indicator module, and a power source electrically connected to the function indicator module. The function indicator module can contain a plurality of light sources that emit paths of light, which can pass through control status indicia to create a visual display on an exterior surface of a projection screen of the electric fireplace. The visual display is visible to a viewer so as to alert the viewer as to the particular status of a control setting of the electric fireplace such as, for example, the temperature of heat produced, the brightness of simulated flames, or the length of time that the user desires for the electric fireplace to operate prior to automatic shutdown.
