Applications
The scope of the RXB controllers is defined by the pre-programmed application
modules.
The following is an overview of the various applications and associated controllers.
The controllers are shipped from the factory pre-programmed with a set of applications.
The required application is then enabled with a tool (ETS, ACS or the "HandyTool").
Due to the fact that the applications are largely pre-defined, engineering simply involves
the definition of a small number of parameters, e.g.:
• 2-position or 3-position control of valves and actuators (depending on application)
• Temperature setpoints
• Manual or automatic fan control
