an inlet to the balloon with a JUNCTION towards the circulator / 3changes, and likewise an outlet of the balloon to the boiler with a JUNCTION on the return of the radiators.
This is the 3 channel valve that will control the priority direction of hot water from the boiler and / or the balloon.

And thanks to the one who integrated the photos on the post rather than the links
