Configuring a load control system

1. A method of configuring a load control system using a graphical user interface software, the method comprising:

displaying a first icon representing a first electrical device;

displaying a second icon representing a second electrical device;

displaying a line from a selected one of the first or second icons to a cursor;

adjusting the line to extend from the selected one of the first or second icons to the cursor as the cursor moves;

receiving a selection of the other one of the first or second icons;

defining a relationship between the first electrical device and the second electrical device in response to the selection of the other one of the first or second icons, wherein the relationship comprises a connection between the first electrical device and the second electrical device;

after the selection of the other one of the first or second icons, ceasing display of the line extending from the selected one of the first or second icons to the cursor such that no line extends between the first and second icons;

displaying on each of the first and second icons an identical notation, wherein the identical notation indicates the connection between the first electrical device and the second electrical device; and

storing the relationship between the first electrical device and the second electrical device.

2. The method of claim 1 , further comprising:

displaying a third icon representing a third electrical device;

displaying a fourth icon representing a fourth electrical device; and

defining a relationship between the third electrical device and the fourth electrical device and fixing a line between the third and fourth icons in response to a selection of the third and fourth icons, wherein the line between the third and fourth icons represents a connection between the third electrical device and the fourth electrical device.

3. The method of claim 2 , further comprising:

displaying a window to allow for a selection of an option defining the connection between the third and fourth electrical devices after fixing the line between the third and fourth icons.

4. The method of claim 3 , further comprising:

ceasing display of the line extending between the third and fourth icons after selection of the option such that no line extends between the third and fourth icons; and

displaying on each of the third and fourth icons an identical notation after ceasing display of the line extending between the third and fourth icons after selection of the option.

5. The method of claim 2 , wherein a line type of the line between the third and fourth icons represents a type of connection between the third electrical device and the fourth electrical device.

6. The method of claim 2 , wherein defining the relationship between the third electrical device and the fourth electrical device further comprises defining a power wiring connection between the third electrical device and the fourth electrical device.

7. The method of claim 5 , wherein the type of connection comprises at least one of a wired communication link or a wireless communication link.

8. The method of claim 2 , wherein defining the relationship between the third electrical device and the fourth electrical device further comprises associating the third electrical device with the fourth electrical device.

9. The method of claim 2 , further comprising:

changing a color of the line between the third and fourth icons after the line is fixed between the third and fourth icons.

10. The method of claim 2 , wherein defining the relationship between the third electrical device and the fourth electrical device further comprises defining the relationship between the third electrical device and the fourth electrical device in response to a selection of the one of a plurality of outputs of one of the third electrical device or the fourth electrical device.

11. The method of claim 1 , further comprising:

displaying a plurality of icons representing a plurality of electrical devices; and

displaying lines from a plurality of selected icons to the cursor.

12. The method of claim 11 , further comprising:

defining a relationship between the plurality of electrical devices and a single electrical device in response to a selection of an icon representing the single electrical device.

13. The method of claim 11 , further comprising:

displaying an error window in response to a selection of a single electrical device after the selection of an icon representing the single electrical device when a number of the plurality of selected icons exceeds a threshold associated with the single electrical device.

14. The method of claim 1 , further comprising:

determining if the first electrical device and the second electrical device are compatible prior to defining the relationship between the first electrical device and the second electrical device;

wherein defining the relationship between the first electrical device and the second electrical device further comprises defining the relationship between the first electrical device and the second electrical device when the first electrical device and the second electrical device are compatible.

15. The method of claim 14 , further comprising:

determining if a third electrical device and a fourth electrical device are compatible; and

displaying an error message when the third electrical device and the fourth electrical device are incompatible.

16. The method of claim 1 , wherein one of the first electrical device or the second electrical device is a control-source device and the other of the first electrical device or the second electrical devices is a control-target device.

17. The method of claim 1 , wherein one of the first electrical device or the second electrical device is a load control device and the other of the first electrical device or the second electrical device is a control-target device.

18. The method of claim 1 , further comprising receiving control instructions from the first electrical device and sending the control instructions to the second electrical device for performing control.

19. The method of claim 1 , wherein the connection between the first electrical device and the second electrical device comprises an electrical connection and an association between the first electrical device and the second electrical device.

20. The method of claim 1 , further comprising:

displaying an occupancy sensor icon representing an occupancy sensor;

displaying a representation of a first occupancy sensor range of the occupancy sensor; and

displaying a representation of a second occupancy sensor range of the occupancy sensor, wherein the representation of the first occupancy sensor range represents a minor motion occupancy sensor range in which minor motions of an occupant are detectable and the representation of the second occupancy sensor range represents a major motion occupancy sensor range in which major motions of the occupant are detectable.

21. The method of claim 20 , wherein the representation of the second occupancy sensor range is larger than the representation of the first occupancy sensor range and encompasses the representation of the first occupancy sensor range.

22. The method of claim 20 , wherein the representation of the first occupancy sensor range and the representation of the second occupancy sensor range are different colors or shades of color.

23. The method of claim 20 , wherein the occupancy sensor is a wall-mounted dual-tech occupancy sensor.

24. The method of claim 20 , wherein at least one of the first occupancy sensor range or the second occupancy sensor range comprise ultrasonic occupancy sensor ranges.
