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.
