The RXB2... room controller is compatible with field devices from Siemens Building
Technologies and with KNX / EIB-compatible third-party devices.
For details, refer to the DESIGO RX hardware overview, CA2N3804.
The RXB2... controllers consist of a housing base, a housing cover and the printed
circuit board with connection terminals. The controllers also have a tool socket, a
service LED and a programming pin.
Housing cover
The programming LED shows the operational status of the room controller as follows:
Green flashing
Red ON
Orange / green flashing
OFF
Other patterns
The programming pin is used to identify the controller in the commissioning phase.
Pressing this pin causes the red programming LED to light up and remain on until
identification of the controller is complete.
Once the programming pin has been pressed, the tool overwrites the hardware address
in the room controller.
If there are no terminal covers fitted, the programming pin may be operated only by a
qualified electrician.
The adjacent terminal may be a live mains voltage conductor.
