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.
Claims6
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.
