Building Technologies RXC34.1 – Room controller, basic module CA2N3847en_02
12.01.2007
When mounting note the following:
• The controller should not be freely accessible after mounting
• Ensure adequate air circulation to dissipate heat generated during operation.
• Easy access is required for service personnel
• Local installation regulations must be observed.
The mounting instructions and a drilling template are printed on the controller
packaging.
The controller and extension modules (e.g. RXC40.1 and RXC41.1) should be mounted
on the same DIN rail, if possible. In any case, the length of the connecting cable must
never exceed 3 meters.

• When different types of extension modules are used, they are mounted in a
specific order for each application, and this must be adhered to.
• The maximum permissible cable length (3 meters) applies to the complete
module assembly.
Commissioning
The RXC34.1 controller is commissioned with the RXT10 commissioning and service
tool. This is connected to the LonWorks® bus via a tool socket (on the controller or
room unit).
The commissioning procedure for the entire DESIGO RXC range is described in detail
in the RXT10 user manual (CA110412).
The labeling fields “Appl.” and “Loc.” are used to indicate the application actually loaded
and the location of the controller, either in writing or by use of printed adhesive labels
(see “Label” under “Mechanical design”).
The direct interrogation of the inputs and control of the outputs with the RXT10
commissioning and service tool is supported as a function of the application.
This
makes it possible to test the installation, and to operate the connected plant
provisionally, before the complete DESIGO RXC system is commissioned.
The LonWorks® bus plug (terminals 19 and 20) can be removed and reconnected at
any time, even while the controller is in operation. Only the original bus plug may be
used.
There is no protection against the accidental connection of AC 230 V on
the AC 24 V side.
