B+B Rain detector

The rain detector is a proven quality product of B+B Thermo-Technik GmbH. Not only customers in the online store, but also professional users in the field of building automation have been relying on this product for years. Now the classic has received a re-design and thus impresses with optimized electronics.

The sensor surface has been optimized so that reliability in difficult operating conditions (e.g. driving rain) is increased. To ensure this, the tips of the sensor surface no longer run vertically downwards, but at an 80° angle. 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 any residual snow. 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 requirements.

Basically, the rain detector is used to control terminal devices in building automation. The rain detector can be used, for example, to automatically control the operation of awnings or skylights. The switching polarity, as well as the sensitivity are adjustable. In the most sensitive setting, the device is also suitable for detecting fog. The mast or wall mounting bracket, which is available as an accessory, enables easy installation.
