Wiring a Viessman Vitotronic 200 in conjunction with an existing 12 zone Taco system

Greetings
I have just replaced a conventional oil fired boiler (that was controlled by an aquastat) with a new Viessmann Vitorond 100 and a Vitotronic 200 Control Unit.
Question is the aquastat on the old unit had T T inputs that were activated by the Taco relay firing the boiler on a demand for heat.
No such connection on the Vito 200 or the Pump Power Module.
The existing house has 9 Zones of radiant with mechanical mixing valves and 3 zones of hi cap baseboard with no mixing valves.
I do not want to redo the existing manifold and all of the circs along with the Taco relays....
How do I make everybody shake hands and play nice?
Also there is a boiler bypass with a circulator to inject supply water into the return header to keep the boiler from condensing. How do I control this circulator?
Thanks

The 200 will operate off of its reset curve. No TT connection is necessary; it's a smart control.Bob Boan

so no connection of any kind between the boiler controls and the taco relays?
Thank you for the input.0 -
No need , the outdoor reset control will shut off the boiler when the outdoor temp rises to the set point ...

Primary secondary piping .. There should be an connection in the control for the boiler circulator .. Size the circulator for was is recommended .
