Control method for electrochromic glazing
First Claim
1. Process of controlling the color-change process of several electrochromic glazings, where the color change of each individual electrochromic glazing is controlled within the color-change interval between an initial value Tstart and a final value Tend by an individual control unit and where the individual control units are activated by a central monitor unit, characterized in that the color-change interval is subdivided into a number of subintervals and that the color change of the electrochromic glazings takes place under the control of the individual control units step-by-step over these subintervals, where the central monitor unit only initiates the color change of the electrochromic glazings over a new subinterval when all satisfactorily operating glazings have completed color change over the preceding sub-interval.

Abstract
A method for controlling the change in color of several sheets of an electrochromic glazing. This color change of the individual sheets within a color-change interval is controlled by individual control units, driven by a central control unit. To achieve a uniform change in color over all the electrochromic glazing sheets, the color-change interval is subdivided into a number of subintervals, whose duration is selected such that the difference in the degree of light transmission between individual electrochromic glazing sheets remains negligible. The individual control units control the change in color of the electrochromic glazing sheets progressively, using the subintervals, whereby the central control unit only begins to change the color of the electrochromic glazing sheets using a new subinterval, once all the glazing sheets which are in perfect working order have completed the change in color that has been performed during the previous subinterval.
