dampers can be controlled separately. Large sound insulation elements ensure quiet ventilation operation. The KWL
MultiZoneBox can be controlled via the control element Eco (KWL-MZB-BE) or the control element Touch (KWL-MZB-
BET). A sensor for humidity (KWL-MZB-F) and a sensor for mixed gas and air quality (KWL-MZB-VOC-F) are available
for demand-controlled, automatic operation.
