The timer in a belt box format is a roller shutter timer designed to fit into a belt box, making this solution ideal for retrofitting. With the timer, your rental apartment can be easily and quickly equipped with more comfort. The daily/weekly program allows your roller shutters to automatically open and close during the week and on weekends. To simulate absence, the integrated random function can randomly delay the switching times. If desired, the roller shutters can be raised and lowered at the same time every day. The size is designed so that the timer in belt box format fits perfectly into the existing belt box opening. Replace your manual belt winder with a roller shutter motor combined with the timer in belt box format for an extra dose of comfort in everyday life. Pulling the belt is a thing of the past! Additionally, in combination with our sun sensor, brightness-dependent control of the visual and sun protection is possible.
