Sorry for creating another thread dealing with same problem, but I would like to try a different approach.
With originally designed 7 zones, the thermostat wiring was only made to 2 locations. Until now I thought it's useless, but I got a new idea.
Since the only piece in this puzzle was missing call for heat, why shouldn't I use these thermostat wires.
One of them leads to first floor, which would take care of slab.
Second goes to second floor, which would do the underfloor.
The question I have, with additional controls, is it possible to get subzoning/branching?
Ex, 2 injection pumps would do 2 temperatures for slab and underfloor. Then, using ex. mixing valves slab would be subzoned into 2 zones (1 would be set on thermostat) and underfloor would be subzoned into 5 zones (again, 1 set on thermostat).
How would You achieve multiple temperatures?
Is my old approach with mixing based on outdoor/supply ratio a real option here or it can be done differently?
