The integrated control ensures perfect interaction of the various components. Equipped with humidity-temperature sensors, the automatic control system ensures efficient ventilation with moisture protection even in the standard version. Optionally the Nexxt can be equipped with the FM-EO radio module for control and communication with other LUNOS components and for Smart Home integration. The heart of the Nexxt is the plug-in unit with heat exchanger:

Nexx-E

The enthalpy heat exchanger achieves a heat recovery rate of up to 83 %. In addition, the mode of operation of the heat exchanger ensures that it is largely ice-free and provides comfort in the interior even with cold outside air.

The Diagnostic Software from LUNOS can be connected to the Nexxt. You can find out about the advantages here.

 

Optional: Electric flap closure

Opens or closes the wall duct automatically when the device is switched on or off.
