The RFZ is a radio controlled product that Systec developed for the Zehnder Group (formerly J.E. Stork Air). This product is suitable for Zehnder’s home ventilation units.
The wireless solution saves installation time and provides a flexibility of installation that conventional wired ventilation units lack. Despite the small size and limited capacity of its 2032 battery, lifespan of this is five years. However, no compromise has been made regarding reliability of the wireless connection: a full handshake protocol guarantees a reliable link.
