Adding a Buderus Logamatic 2107 - Piping changes needed?

I have a Buderus G124x boiler about 15 years old with indirect DHW. Four zones total, some radiant, some BB, some panels. Four circulators with a mixing valve on the radiant.

Generally speaking, is the 2107 install mainly electrical or are there usually piping changes needed? Looks like I can keep my taco zone panels (tstat controlled) and have the 2107 control DHW and the boiler temp. I know I'd have to install the outdoor reset and temperature sensors for DHW/boiler. Is there much else to it besides moving some wiring and programming?

With the lower temps needed for the newer emitters I'm hoping to see some savings on my gas bill. Unbelievable how infrequent the radiant runs compared to BB.

    Without seeing your system, it can’t be absolutely stated that no piping changes should be made, but normally no changes are necessary.
