Installation Diagram

Graphic or Wiring diagram of Loxone Multi Extension Air installed. In the diagram you see the Multi Extension Air installed in a separate panel to the right of the Miniserver Gen 2 panel. Both are powered by separate 24VDC power supplies. The Miniserver, the power supplies and the Multi Extension Air are installed on DIN rails which are attached inside the panels.
To the left of the Miniserver is a DIN rail mounted 24VDC power supply. The power supply has a 2-conductor wire connected to the Miniserver to provide 24VDC power. From the top of the Miniserver is also a line indicating its attachment to the LAN via a network switch which is located outside and on the top of the panel.
To the left of the Multi Extension Air is a 24VDC power supply. The power supply has a 2-conductor wire connected from the DC outputs of the power supply to the DC inputs of the Multi Extension Air. The Multi Extension Air communicates with the Loxone Miniserver wirelessly using Loxone Air technology, which is a radio frequency based protocol.
