A building control device includes a printed circuit board including control circuitry for controlling at least part of the building control device. An LCD display is operatively coupled to the printed circuit board and is controlled at least in part by the control circuitry of the printed circuit board. A plurality of LEDs are operatively coupled to the printed circuit board and are controlled at least in part by the control circuitry of the printed circuit board. An opaque plate defines an at least translucent arc-shaped region that extends around at least part of the LCD display. A light guide is situated behind the opaque plate and is configured to be illuminated by the plurality of LEDs such that light from the light guide is visible through the at least translucent arc-shaped region of the opaque plate.

A building control device includes a printed circuit board (PCB) assembly with a controller. A lighting assembly is operatively coupled to the PCB and is controlled by the controller. The lighting assembly includes a light guide that extends around a periphery of an interposing region. The light guide having a front face and one or more light sources optically coupled to the light guide such that light provided by the one or more light sources enters the light guide and is distributed to the front face of the light guide to provide a diffuse light output. A cover forms at least part of a front face of the building control device and includes a transparent region in registration with at least part of the front face of the light guide.
