Claims27
A system for modulating the transmission of light comprising an electrochromic glazing;
- a control system;
- and an identification circuit in communication with at least one of said electrochromic glazing or said control system, wherein said identification circuit comprises at least one parameter associated with said electrochromic device;
- and where said control system monitors said identification circuit and applies said at least one stored parameter in operation of said electrochromic device.
A method of powering a system comprising an electrochromic glazing comprising:
- (a) setting said electrochromic glazing to a clear state;
- (b) applying a predetermined voltage to said electrochromic glazing;
- (c) measuring an actual voltage applied to said electrochromic glazing;
- (d) calculating a wire resistance of said system;
- and (e) adjusting subsequently applied voltages based on said calculated wire resistance.
