Building Technologies RXC34.1 – Room controller, basic module CA2N3847en_02
12.01.2007
Compatibility
The RXC34.1 controller can be combined with extension modules, such as the
RXC40.1 for lighting control (data sheet 3842) and the RXC41.1 for the control of blinds
(data sheet 3843). In such cases, the RXC34.1 controller must be loaded with an
application which matches the selected combination of extension modules. The
possible combinations and the associated applications are described in the applications
library (CA110300).
For operation, a room unit from the QAX3… series may be used in conjunction with
conventional momentary contact switches for lighting control, or the flexible room units,
QAX50.1 or QAX51.1 may be used.
Refer to the RX hardware overview, document CA2N3804 for an overview of the
available field devices.
Design
The RXC34.1 controller consists of a housing base, a housing cover and the printed
circuit board with connection terminals. The controllers also have a connector base for
the extension modules, a tool socket, a service LED and a service pin.

Terminal covers (RXZ30.1) are available as an option to protect the connection
terminals from physical contact and dirt. The terminal covers must be used on
equipment mounted outside the control panel or distributor box.
When fitting the terminal covers, make sure that they lock into position correctly. These
covers also provide strain relief for the cables connecting the extension modules.
The service LED remains visible when the terminal covers are in place, and the service
pin can be operated with a pointed implement.
