added zone 4 and 5, when having extra vr70 coupled to system

[garageboxnv]

I have added 2 extra zone/heating circuit definitions to the vrc700 definition, as my system is extended with another vr70 adding 2 zones
A suggestion for improvement could be to have the zone values be defined once abstract (maybe a template) and refer to this with the last byte in how many zones are defined. (e.g. Z1=0x0, Z2=0x1, Z3=0x2, Z4=0x3,...)
Theoretically a system can be extended with more vr70's

P.S. I like the improvement of templates, it gave me the possibility to understand the messages better

This is a great addition - at least for me. I actually have 2 VR70s and 1 VR71. As far as I know this is the max setup. Can you consider adding Hc6 and Hc7 as well? Local config works more or less, though the online config files have also a number of benefits for normal users - like me.
