Use
The RXC39.5 room controller is optimized for control of fan-coil systems with ECM
fans in individual rooms.
The controller application is determined by downloadable application software, also
referred to simply as the “application”. The various applications and the associated
functions are described in detail in the applications library: CA110300.
The controller is delivered with basic application 00039. The basic application, which
contains only I/O module functions, is overwritten with the definitive application in the
commissioning phase. The RXT10 commissioning and service tool is used for this
purpose (see “Commissioning”).
In conjunction with a building automation and control system, the RXC39.5
controller can also be used as a universal I/O module, e.g. to register digital signals
or to control various equipment (ON/OFF or modulating). In this case the controller
is loaded with basic application 00039. The inputs can then be read and the
outputs overridden via the building automation and control system.
Functions
The controller functions are determined by the selected application and its parameters.
For a detailed description of functions refer to the Desigo RXC applications library
CA110300.
