Wiring 2 port zone valve to Wiser UFH controller

[wheelsandcogs]

Hi, I'm currently wiring up a Wiser UFH Controller for the first time.

The wiring for the pump seems relatively straightforward as it only has 3 cores (L, N, E). I have a Reliance 2-port motorised valve on the flow to the manifold. The valve cable has 5 cores (blue, brown, yellow/green, grey, orange) - see diagram.

I'm following the instructions for the UFH controller 230V AC wiring from https://www.productinfo.schneider-electric.com/wiser_home/wiser-underfloor-heating-connection-strip_...

Which says "connect B2 to zone valve". I'm assuming that I need to also connect L, N and Earth via a wago block? But which cable (orange or grey) do I connect to B2? And what do I connect the other one to?

Thanks.

Hi @wheelsandcogs ,

Thanks for your post.

In fact, you need to connect :

the Blue wire to the Neutral, also with N1/N2/N3

the Brown wire to B2

the Line to B1

No need to connect the Grey and Orange wires.
