Abstract

Networks of electrochromic windows and methods of commissioning the windows on such networks are described. The commissioning may involve determining where each electrochromic window is installed and/or which controller is associated with which electrochromic window. In various cases, a number of windows may be simultaneously commissioned.

First claim

What is claimed is:

1. A method of determining associations between window controllers and associated electrochromic windows installed in a network, the method comprising:
(a) providing instructions to each window controller to transition its associated electrochromic window(s) to a commissioning state, wherein the commissioning state varies between electrochromic windows associated with different window controllers;
(b) after (a), recording the commissioning states of the electrochromic windows;
(c) repeating (a) and (b) at least once such that each electrochromic window experiences a series of commissioning states, wherein the instructions provided to the window controllers provide a unique series of commissioning states for each window controller being commissioned; and
(d) determining the association between the window controllers and their associated electrochromic windows by comparing the instructions provided in each iteration of (a) with the commissioning states observed in each iteration of (b).

2. The method of claim 1 , wherein the series of commissioning states comprises three or more different tint states.

3. The method of claim 2 , wherein the series of commissioning states comprises four or more different tint states.

4. The method of claim 1 , wherein the series of commissioning states comprises two or more different static tint states and one or more transitory tint states.

5. The method of claim 1 , wherein (b) comprises taking a photograph or video of the electrochromic windows.

6. The method of claim 5 , further comprising processing the photograph or video using a program comprising image processing software to determine the commissioning states of the electrochromic windows.

7. The method of claim 6 , further comprising manually overriding a commissioning state determination made by the program to correct the commissioning state of an electrochromic window whose commissioning state was incorrectly determined by the program.

8. The method of claim 6 , wherein the program is configured to match a set of electrochromic windows in a first photograph with the same set of electrochromic windows in a second photograph, the first and second photographs being taken at different times.

9. The method of claim 1 , wherein determining the association between the window controllers and their associated electrochromic windows comprises determining which window controller is connected with which electrochromic window(s).

10. The method of claim 1 , wherein the network of electrochromic windows comprises two or more groups of electrochromic windows, and wherein the method of claim 1 is performed simultaneously on each group of the two or more groups of electrochromic windows.

11. The method of claim 1 , further comprising collecting current and/or voltage data corresponding to the current and/or voltage experienced by the electrochromic windows during an optical transition, and comparing the collected current and/or voltage data to expected current and/or voltage data to thereby confirm the associations determined in (d) between the window controllers and their associated electrochromic windows.

12. The method of claim 1 , wherein the window controllers simultaneously transition their associated electrochromic window(s).

13. A method of determining associations between window controllers and associated electrochromic windows installed in a network, each electrochromic window comprising a light, the method comprising:
(a) providing instructions to each window controller to display a light pattern on the light of the window controller's associated electrochromic window(s), wherein the light patterns are unique for each of the window controllers;
(b) recording the light patterns displayed on the lights of the electrochromic windows; and
(c) determining the association between the window controllers and their associated electrochromic windows by comparing the instructions provided in (a) with the light patterns observed in (b).

14. The method of claim 13 , wherein the lights comprise light emitting diodes (LEDs).

15. The method of claim 13 , wherein (b) comprises taking a photograph or a video of the electrochromic windows.

16. The method of claim 15 , further comprising processing the photograph or the video using a program comprising image processing software to determine the light pattern displayed by the lights of the electrochromic windows.

17. The method of claim 13 , wherein determining the association between the window controllers and their associated electrochromic windows comprises determining which window controller is connected with which electrochromic window.

18. The method of claim 13 , wherein the network of electrochromic windows comprises two or more groups of electrochromic windows, and wherein the method of claim 13 is performed simultaneously on each group of the two or more groups of electrochromic windows.

19. The method of claim 13 , wherein the light patterns are simultaneously displayed on the lights of the electrochromic windows.

20. The method of claim 13 , wherein the electrochromic windows are provided in IGUs, each IGU comprising at least two panes, wherein the lights of the electrochromic windows are provided between the panes of the IGUs.

21. The method of claim 20 , wherein each IGU comprises a spacer, and wherein the lights of the electrochromic windows are provided flush with the spacers.

22. The method of claim 13 , wherein each electrochromic window comprises a pane, and wherein the lights of the electrochromic windows are provided on the panes of the electrochromic windows.

23. The method of claim 22 , wherein the electrochromic windows are provided in IGUs, each IGU comprising at least two panes and an interior region defined between the two panes, wherein the lights of the electrochromic windows are provided outside of the interior region of the IGUs.

24. The method of claim 13 , wherein the lights of the electrochromic windows are provided in a viewable area of the electrochromic windows.
