VELUX windows and curtains This can control a group of windows with the function (open/close or up/down) or scenes in which you choose to have your windows open for 10 minutes when you get home, or always close at 10 pm or when the temperature drops below 20 degrees. . We put in the ZVS200, which controls the window. We create a scene in which we connect one or more MATRIX buttons to the window(s), curtains or anything else controlled by Io-Homecontrol. This requires the remote controls to be in the house at installation. We put in a ZVS200 that takes care of these devices. We connect VELUX windows and VELUX blinds to the QuickApp in the scene during installation - this requires that the remote controls are in the house during installation. You must accept the Terms of Use and Privacy Notice before using this QuickApp. You can also extend the scene yourself to control multiple devices. Automatic extractor hood You can have the ventilation flap in the VELUX window open automatically when the cooker hood is turned on. We put a consumption meter on the cooker hood to measure whether it is in use and opens or closes the ventilation flap. You don't have to do anything.
