The inner panel is one of the main components of the inVENTer-Connect radio system and replaces the standard inner covers of the ventilation units iV-Smart +, iV14-Zero, iV-Compact and iV-Light to enable integration into the radio network. In addition to the radio interface, the Connect inner panel has local control electronics, a power supply unit and an automatic shutter. In the flush-mounted version, the Connect inner cover is flush with the wall when closed and is therefore almost invisible.
