A thermostat for a building space includes a touch screen user interface, a selector, a single-touch controller, and a multi-touch controller. The touch screen user interface is configured to present display data to a user and receive touch-based input from the user. The selector is configured to select an operating mode for the touch screen user interface based on one or more environmental conditions of the building space. The single-touch controller is configured to operate the touch screen user interface in a single-touch operating mode when the single-touch operating mode is selected by the selector. The multi-touch controller is configured to operate the touch screen user interface in a multi-touch operating mode when the multi-touch operating mode is selected by the selector.
