Fields of application
The scope of RXB is defined by the preprogrammed application software. The following pages provide an overview of the options and the
corresponding devices, divided into different areas of application. The devices are supplied preprogrammed with the applications. The required
application can be selected by means of the ETS, Synco™ tool or the Handy tool QAX34.3.
Due to the fact that the applications are predefined, engineering simply involves the definition of a small number of parameters, e. g.:
n PWM or or 3-point control of the valves and actuators (RXL39.1: 0-10V DC control of motoric actuator)
n Temperature setpoints
n Manual or automatic fan control
Fan coil systems
