Abstract

An HVAC controller is described that is configured to be more intuitive and user friendly to program and operate than convention HVAC controllers. In some instances, the HVAC controller may include a touch screen interface that provides greater flexibility in displaying information to the user and/or soliciting information from the user.

Claims

1. An HVAC controller configured to control one or more components of an HVAC system that can operate to control an environmental condition of an indoor space of a building, the HVAC controller comprising:

a display;

a controller in communication with the display, the controller configured to;

display on the display a setpoint adjustment element for assisting a user in selecting an appropriate setpoint value for the environmental condition from a range of available setpoint values, the setpoint adjustment element concurrently displaying two or more sub-ranges on the display, wherein each of the two or more sub-ranges is labeled with at least one descriptive word that provides a qualitative indication of the setpoint values that fall within the corresponding sub-range, wherein a selected setpoint value corresponds to a desired value for the environmental condition within the building; and

operate an algorithm that at least partially controls the one or more components of the HVAC system in accordance with the selected setpoint value to drive the environmental condition in the indoor space of the building toward the selected setpoint value.

2. The HVAC controller of claim 1, wherein the setpoint adjustment element further displays a quantitative value for the selected setpoint value.

3. The HVAC controller of claim 2, wherein the quantitative value for the selected setpoint value is a numeric value.

4. The HVAC controller of claim 1, wherein at least one of the two or more sub-ranges corresponds to a predetermined range of the available setpoint values that is associated with a comfort range for the environmental condition.

5. The HVAC controller of claim 1, wherein the setpoint adjustment element includes an indicator that can be moved by the user along the range of available setpoint values to change the selected setpoint value, wherein moving the indicator from a minimum available setpoint value to a maximum available setpoint values results in a monotonic increase in the selected setpoint value.

6. The HVAC controller of claim 1, wherein the setpoint adjustment element includes a slider control that permits the user to change the selected setpoint value by moving a slider button between a first end and a second end of the slider control.

7. The HVAC controller of claim 6, wherein the slider control includes a horizontal bar, and wherein the slider button is slideable along the horizontal bar.

8. The HVAC controller of claim 7, wherein moving the slider button to the left reduces the selected setpoint value, and moving the slider button to the right increases the selected setpoint value.

9. The HVAC controller of claim 8, wherein the display is a touch screen display, and the slider button is moved left and right by touching the slider button on the touch screen display and dragging the slider button to the left and to the right.

10. The HVAC controller of claim 6, wherein the slider control further comprises a left button and a right button, wherein the slider button is movable right by activating the right button and left by activating the left button.

11. The HVAC controller of claim 6, wherein slider button includes a quantitative value of the selected setpoint value.

12. The HVAC controller of claim 1, wherein the setpoint adjustment element displays at least three distinct sub-ranges including a first sub-range of setpoint values, a second sub-range of setpoint values, and a third sub-range of setpoint values, and wherein the setpoint adjustment element further includes first, second and third labels that each provide a qualitative indication of the setpoint values that fall within each of the first, second and third sub-ranges, respectively, wherein one of the sub-ranges is indicated by its label as corresponding to a comfort range for the environmental condition.

13. The HVAC controller of claim 12, wherein the first label is located to the left of the second label, and the second label is located to the left of the third label.

14. The HVAC controller of claim 1, wherein the selected setpoint value comprises a humidity setpoint value.

16. The HVAC controller of claim 1, wherein the setpoint adjustment element further displays a quantitative value for the selected setpoint value.

15. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:

a user interface including a display;

a controller in communication with the user interface including the display, the controller configured to operate an algorithm that at least partially controls the one or more components of the HVAC system according to a selected setpoint value received from a user via the user interface; and

the controller configured to display on the display a setpoint adjustment element for selecting a selected setpoint value from a range of available setpoint values, the setpoint adjustment element including at least three distinct sub-ranges along the range of available setpoint values, wherein each of the at least three distinct sub-ranges includes a label that provides a qualitative indication for the setpoint values that fall within that sub-range, and wherein at least one of the at least three distinct sub ranges defines a comfort range of setpoint values bounded by a lower range and a higher range of setpoint values.

17. A method for assisting a user in selecting an appropriate setpoint value of an HVAC controller from a range of available setpoint values for an environmental condition of an indoor space of a building serviced by the HVAC controller, the method comprising:

displaying a setpoint adjustment element on a display, wherein the setpoint adjustment element concurrently displays two or more sub-ranges along the range of available setpoint values, wherein each of the two or more sub-ranges is labeled with at least one descriptive word that provides a qualitative indication of the setpoint values that fall within the corresponding sub-range, the setpoint adjustment element also displaying an indicator that can be moved by the user along the range of available setpoint values to select a selected setpoint value;

receiving a selected setpoint value by monitoring the indicator of the setpoint adjustment element; and

operating an algorithm in an HVAC controller to at least partially control one or more components of an HVAC system in accordance with the selected setpoint value to drive the environmental condition in the indoor space of the building toward the selected setpoint value.

18. The method of claim 17 further comprising displaying a quantitative value of the selected setpoint value on the display.

19. The method of claim 17, wherein moving the indicator from a minimum available setpoint value to a maximum available setpoint values results in a monotonic increase in the selected setpoint value.

20. The method of claim 17, wherein at least one of the two or more sub-ranges corresponds to a predetermined range of the available setpoint values that is associated with a comfort range for the environmental condition.
