The silent ECO EC residential ventilator series has the lowest power consumption of all air volume flow ventilators on the market. Its full range of features is controlled by the WERNIG DC module equipped with NFC technology. Setup is done via the ECO EC app, which allows the installer to adjust all features based on conditions on-site and to transmit these settings to all further residential ventilators installed. The ventilation unit is backward compatible to allow a technology upgrade in already installed devices. Its subtle appearance and high manufacturing quality meet the exacting standards of modern architecture.
