Schellenberg 22639 Daylight sensor

The Sunsensor for ROLLODRIVE 35 and 45 measures the light value on the window and causes the electric belt winder to open or close the shutter automatically. The sensor is simply attached to the inside of the window pane with a suction cup and connected to the RolloDrive with a 1.5 m long plug cable.If a set light value is exceeded for approx. 10 minutes, the roller shutter closes automatically. After approx. 20 minutes, the roller shutter will move up a little so that the sensor can again measure the brightness. If the light value remains constant, the roller shutter is held in this position. If the light value is undercut, the roller shutter returns to the upper end position. In this way, furniture and plants can be protected from strong sunlight. The light value can be set individually between 3,000 lux and 10,000 lux. A further power connection is not necessary because the sun sensor is supplied with power via the electric belt winder.This text is machine translated.
