Abstract

A graphical user interface system for a thermal comfort controller. The user interface system has a central processing unit coupled to a memory and a touch sensitive display unit. The memory stores a temperature schedule data structure and perhaps a temperature history data structure. The temperature schedule data structure is made up of at least one set-point. The temperature history data structure is made up of at least one Actual-Temperature-Point. The display presents the set-points and/or the Actual-Temperature-Points. One representation of the display is a graphical step-function. The user uses a finger or stylus to program the set-points by pointing and dragging a portion of the step-function.

Claims

1. A method for programming a thermal comfort controller with a user interface system having a central processing unit, a memory means for storing a temperature schedule data structure having at least one set-point, where the set-points each associate a desired temperature to a desired time, and a display unit with a touch-sensitive screen, the memory means and the display unit both coupled to the central processing unit, the method comprising:

graphically displaying the set-points on the display unit;

choosing the at least one set-point from the temperature schedule data structure;

entering a set-time for the at least one set-point on the display unit,

entering a set-temperature for the at least one set-point on the display unit; and

updating the at least one set-point in the temperature schedule data structure with the set-time and the set-temperature.

2. The method for programming a thermal comfort controller from claim 1, wherein the step of graphically displaying, the set-points are displayed as a step-function with a first axis for denoting time, and a second axis for denoting temperature.

3. The method for programming a thermal comfort controller from claim 2, wherein the step of entering the set-time comprises dragging a first graphical line of the step-function from its current location on the step-function to a new position relative to the first axis.

4. The method for programming a thermal comfort controller from claim 2, wherein the step of entering the set-temperature comprises dragging a second graphical line of the step-function from its current location on the step-function to a new position relative to the second axis.

5. The method for programming a thermal comfort controller from claim 1, wherein the user interface further comprises a stylus for allowing a user to program the set-points on the display unit.

6. The method for programming a thermal comfort controller from claim 1, further comprising:

providing a temperature history data structure having at least one Actual-Temperature-Point, where the Actual-Temperature-Points each associate an actual temperature to an actual time;

graphically displaying the temperature history data structure; and

wherein the memory means stores the temperature history data structure.
