Basically, the rain detector is used to control end devices in building automation. The rain detector can e.g. the operation of awnings or roof windows can be controlled automatically. The switching polarity and the sensitivity are adjustable. In the most sensitive setting, the device is also suitable for detecting fog. The mast or wall bracket available as an accessory enables easy installation.



The sensor surface has been optimized so that the reliability is increased in difficult operating conditions (e.g. driving rain). To ensure this, the tips of the sensor surface no longer run vertically downwards, but at an angle of 80 °. In addition, the individual areas of the sensor surface are now significantly narrower and thus detect rain and snow more reliably. In addition to the optimized sensor surface, automatic activation of the sensor heating has also been integrated. This is only active when the sensor surface is wet and is used to quickly dry the sensor surface and remove snow residues. In addition, there is now an adjustable switch-off delay in the rain detector. This can be set individually to approx. 90 to 330 seconds, depending on the requirements.
