The RXT20.1 service terminal is used for simple diagnostics of room controllers and
room units, and for remote operation of the DESIGO RXB and RXC controller service
pins. The built-in connecting cable of the service terminal is plugged directly into the
roomcontroller to be interrogated, or into the room unit of the controller concerned.
The service terminal displays the status of the controller and room unit, the "wink" func-
tion, error messages or additional information of the room unit.
The service pin of the connected DESIGO RXB / RXC controller can be operated re-
motely with the function keys on the service terminal. This function is especially useful
