The configuration is now split into parts. It may need refining and formatting some commands once the issues are resolved.

Bundle works nicely. I personally use general, hwc, hc1, and zone1 and my system works much faster than with all the commands.

Only one new issue appeared in a meantime and is not tied to the separation of files.  
A problem occurs when polling a sensor that is not connected to the system if its datatype is EXP (float). In this case, VRC 700 returns FF FF FF 7F, a value that can not be converted into float due to excessive exponent (according IEEE 754). Another Vaillant special case ☹ . On the other hand, this should be the last one for this configuration. 🙂
