How does Heatmiser control radiators + HW undefloor heating ?

[Pali]

Hi, thanks for looking. Keen to get some advice please

Boiler: Valiant 637 connected to a 300l Megaflow.
13 Zones in total (6 Radiator + 7 HW Under floor heating)
Each to be individually controlled via a Heatmiser solution (Wired solution).

Keen to understand how each of the individual thermostats (Neo Stat) will tell each individual radiator valve to open and close deepening on the temperature required.

I am comfortable with the app, the thermostats etc, but need advice on the manifolds v motorised valves etc please

I think I have 3 options. Keen for advice please
1) 14 port manifold & 2 Heatmiser Wiring Centres UH8
2) 2 x 8 Port manifolds & 2 Heatmiser Wiring Centres UH8
3) 8 port manifold (for UF HW) + 6 motorised valves (for rads) & 2 Heatmiser Wiring Centres UH8

Please advise which is best. From an electricians perspective, all are ok. Keen to get view from a plumbing perspective please. What are the pro and cons of each

Solution simple:

Mixing manifold for the UFH
Non-mixing manifold for the rads.

As for your preferences for controlling each radiator or UFH zone, run as many thermostats as you like back to the dedicated manifold.

From each manifold run a wire back to the boiler.

As for the correct wiring setup, it sounds like you have it covered - hopefully?

Thanks so much.
So option 2 is the one
What is the difference between a mixing and a non-mixing manifold?

Mixing one is for ufh, so needs reducing in temperature with mixing valve and non mixed, or direct manifold will do the radiators at boiler temp.
