Siemens RXC10 – Room controller CA2N3830en_06
Building Technologies 2015-12-23
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”).
With all applications (including basic application 00010), the inputs can be interrogated
and the outputs overridden using the RXT10 commissioning and service tool.
