The timer in a roller shutter box format is a roller shutter timer designed to fit within a roller shutter box, making it ideal for retrofitting. With this 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 fits perfectly into the existing roller shutter box opening. Replace your manual roller mechanism with a roller shutter motor combined with the timer in roller shutter box format for an extra dose of comfort in everyday life. Pulling the cord is a thing of the past! Additionally, when combined with our sun sensor, brightness-dependent control of visibility and sun protection is possible.
