RolloTron Standard 1340 mini-belt belt winder, 15 mm belt width - for motor-assisted and automatic shutter control. The modern RolloTron Standard shutter drive makes shutter control easy and practical. RolloTron Standard mini-belt is installed in conventional belt boxes with a width of 36 mm or more. The illuminated status display shows the current settings. Below it are the control keys, which make intuitive manual control possible. An automatic time-based raising and lowering of the shutters is possible via the memory function, which allows the specified actions to be repeated on a 24-hour cycle. In addition, RolloTron Standard can also control the shutters on the basis of the outdoor light level if a sun and twilight sensor is connected via the port provided for this purpose. Thanks to the soft-start/soft-stop function, it runs particularly smoothly and gently, without abrupt acceleration. Functions / compatibility: - Can be controlled in conjunction with the sun and twilight sensor
