FAKRO - Rain Sensor for Electric Windows (ZRD)

Never worry about leaving your roof windows open again - the Fakro ZRD Rain Sensor takes care of it for you. Designed to work with the Fakro ZWMP weather module and Z Wave compatible actuators, this smart sensor automatically closes your roof windows at the first sign of rain - keeping your attic safe, dry and protected.

Engineered for reliability in all weather conditions, the ZRD features a built in heating element that prevents false triggers from mist or dew, so it only responds to real rainfall. Its also designed with safety in mind: when integrated into smoke ventilation systems, the sensor intelligently ignores rain signals during emergency smoke extraction while staying fully active for normal ventilation. 

Compact, discreet (55x50x13 mm), and easy to install, the ZRD mounts directly onto exposed roof sections and comes with a 5m power cable for flexible placement. Powered by an 8-32V DC supply, it ensures dependable protection, rain and shine.
