Wall-mountable temperature control device for a load control system having an energy savings mode

摘要

A wall-mountable temperature control device having a vertically-arranged temperature adjustment actuator for adjusting a setpoint temperature of a temperature control system to thus control a present temperature in a 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 and setpoint temperature visual displays 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.

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 for adjusting a system setpoint temperature of the temperature control system to thus control the present temperature in the building, the temperature control device having a vertically-arranged temperature adjustment actuator for adjusting a base setpoint temperature, 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 system 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 system setpoint temperature 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 determine the present temperature of the building, the controller operable to receive a digital message including an energy-savings preset and to determine a setback temperature in response to the energy-savings preset, the controller operable, in response to receiving the digital message, to increase the system setpoint temperature to be equal to the base setpoint temperature plus the setback temperature when cooling the building and decrease the system setpoint temperature to be equal to the base setpoint temperature minus the setback temperature when heating the building so as to decrease the power consumption of the heating and cooling system, wherein the controller does not adjust the setback temperature in response to adjustments of the base setpoint temperature; 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 changes in 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 system setpoint temperature is adjusted in response to changes in the base setpoint temperature or the setback temperature of the energy-savings preset.
