In order to control electrochromic glasses, Octoglass developed and patented its own controllers KDS-2 and KDS-2 mini, and more recently the development of a new and compact controller KDS-2 nano was started. Our devices allow us to avoid the degradation of electrochromic devices due to the fact that we program our controllers at the manufacturer’s plant directly under the load that he will face when working with a particular glass. In addition, the user can independently reconfigure most of the custom functions of the controller to suit his needs. Controllers can be controlled using buttons, switches, encoders and for remote control, remote control modules are connected to the controller.
