Building Technologies 2015-12-23
The application software for the complete unit, comprising the basic module and the
extension module(s) is downloaded into the basic module, the RXC30 or RXC31 room
controller. If the RXC30 / RXC31 / RXC38 controller is downloaded with basic appli-
cation 00030 / 00031, test functions for the RXC40 extension module are also availa-
ble.
Functions
The functioning of the RXC40 extension module is defined by the application software
downloaded into the RXC30 or RXC31 / RXC38 room controller.
For a detailed description of functions, refer to the DESIGO RXC applications library
(V1: CA2A3810, V2:CA110300).

Compatibility
The RXC40 extension module is always used in conjunction with an RXC30 or RXC31 /
RXC38 room controller (data sheet 3840 / 3844 / 3841). If required, an RXC41 exten-
sion module (data sheet 3843) can be added, for the control of blinds. Possible combi-
nations and the associated applications are described in the DESIGO RXC applications
library (V1: CA2A3810, V2:CA110300).
For operation, either conventional momentary-contact switches or the flexible room
units, QAX50 or QAX51 may be used.
If different types of extension module are used, they must be arranged in the following
order: RXC30  RXC40  RXC41, RXC31  RXC40  RXC41, or RXC38  RXC40
 RXC41
