Abstract:
A line of sight temperature sensor in a thermostat allows placement at locations other than on a wall. For example, the thermostat is positioned in a ceiling, allowing easier wiring access. Wall placement may be used. By remotely sensing user selection associated with a remote location, control of the building automation is provided without requiring user contact. For example, the user places a finger or hand on a graphic for increasing or decreasing temperature set point. The placement is detected with an optical or other remote sensor. The set point for heating or cooling control is altered based on the remote sensing of the user selection.
