Excluding packaging
The tool socket on the room unit provides access to the connected individual room
controller via the commissioning and service tool or the service terminal.
The bus cable (Terminals 3 and 4) is therefore looped to the tool socket (Pins 1 and 2).
The bus cable is not affected by the room unit.
For connection of a service terminal, the PPS2 interface (Terminals 1 and 2) is also
connected to the tool socket.
