摘要: A control system for an electrochromic (EC) device is capable of monitoring the temperature EC without requiring external element, and then controlling based, in part, upon readings. The also provides methods heating using current flowing through simultaneously changing transmissivity level device. controller security feedback by detecting glass breakage via a high frequency impedance measurement determining bleaching/coloring history device, transmission state applying holding voltage to maintain
