Velux KLN 300 Active Departure Switch
Velux Active Departure Switch is designed to be used as either a handheld device or attached to a wall near to exit doors of a house. The switch will put the windows in and out of safe mode when leaving the house. When in safe mode, the windows are locked and limited to provide ventilation only. This keeps the air quality within the home high while also keeping the house secure and protected. Needs to be used with the Velux Active Kit.
