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