Abstract

An apparatus for the control of an electrochromic window having a three-electrode structure (2, 8, 5) comprises a comparator (12) to maintain within safe limits the potential difference of the electrode (2) and the reference electrode (5), and a shunt unit (16) to switch off the power supply when the current falls below a lower limit and a unit for controlling the colouring density on the basis of the quantity of charge supplied or the optical density of the colouring.
