Abstract
The thermostat includes a housing having at least a portion thereof illuminated by a light that changes color via a manual input. The light illuminates the display for easy readability while the variable color of the light allows a user to match the appearance of the thermostat to best complement the surrounding décor. User input elements provide for the manual adjustment of one or more characteristics of the light, such as visible color of the light. The light source comprises at least one LED for displaying a plurality of colors. In this case, to change the color of the light illuminating the translucent portion of the housing or backlighting the display, electronics within the thermostat control the drive signals to the LED in order to operate the LED to provide the desired color. The invention also contemplates filtering the light and manually adjusting the filtering to provide the desired aesthetics.
