1. A temperature control system for controlling a present temperature of a building having a heating and cooling system, the temperature control system comprising:

  • a wall-mountable temperature control device having a vertically-arranged temperature adjustment actuator for adjusting a setpoint temperature of the temperature control system to thus control the present temperature in the building, a room temperature visual display for displaying a visual representation of the present temperature of the building, and a setpoint temperature visual display for displaying a visual representation of the setpoint temperature, the room temperature visual display and the setpoint temperature visual display each comprising a linear array of light-emitting diodes arranged parallel to the temperature adjustment actuator and controlled such that one of the light-emitting diodes of the setpoint temperature visual display is illuminated to display the setpoint temperature in response to the actuations of the temperature adjustment actuator and one of the light-emitting diodes of the room temperature visual display is illuminated to display the present temperature of the building; and

    a controller operable to adjust the setpoint temperature and to determine the present temperature of the building, the controller operable to receive a preset digital message including an energy-savings preset and to determine a setback temperature in response to the energy-savings preset, the controller operable to increase the setpoint temperature by the setback temperature when cooling the building and to decrease the setpoint temperature by the setback temperature when heating the building so as to decrease the power consumption of the heating and cooling system;

    wherein the one of the light-emitting diodes of the room temperature visual display that is illuminated to display the present temperature is adjusted in response to the present temperature of the building determined by the controller, and the one of the light-emitting diodes of the setpoint temperature visual display that is illuminated to display the setpoint temperature is adjusted in response to the setback temperature of the energy-savings preset.
