Plumber struggling with vr66 install vaillant

[mcmoby69]

Brown cores @ motor valves terminate to neutral as do neutrals terminate to live..why???

Coz it's been wired by a complete ****wit.

What else is wrong with the install?

Feck me... My wife could do a better job of the wiring.

No professional is doing this

The OP is doing these works....serves him right..
Can you imagine what the rest of the place looks like??

Is stevie wonder struggling to make ends meet?

The wiring will work ok as is, (although you should get the live and neutral wires on the zone valve connections the right way round just to be tidy ) you should check the polarity of the ebus connections.

The manual states polarity does not matter in bus?

Ok I've updated based on feedback. Still same error. Should I use voltage tester to see at which point link is being made?

Kinda makes you wonder why they put a warning triangle with the polarity next to it.

Do you have a "1" showing in the mode selector knob ?

That is hard to believe, 99% of multi-point data bus systems are polarity sensitive,

Ok another update. No errors. But the hot water isn't now coming. I've made sure the valve is set to auto

Call someone who actually knows what they are doing.

@picasso is on it

Is the orange, as suggested by some, really needed with Ebus control?

I thought the Ebus controlled all functions.

Indeed.

Ditch the VR66 and use normal Honeywell junction box, easy to wire
