Tado extension kit - wiring into Baxi 830 combi.

[stek2011]

Any Tado experts lurking here?

I had a go at connecting a Tado Wired Extension Kit (wired so it supports OpenTherm) to our Baxi 830 boiler earlier.
All seemed to go well according to the app - but changing the thermostats right down to zero doesn't seem to do anything to the heating and the rooms just keep getting hotter and hotter...

Does this wiring look correct?

The power is coming from a separate plugged cable (as advised by the Tado app).

Any pointers/confirmation that it looks right would be appreciated...

Thanks,
Steve

Have you still got the 240 v link in

Plus 1 for this, the yellow loop in your first picture looks like it might be.

Hi @cross thread - thanks for replying.

The Tado app advised me I needed to buy a separate power cable so I have a plug to two core cable providing the power to the extension kit. (it is powering up correctly from a socket).
The blue and brown cables are capped with insulation caps at both ends...

Is that what you meant?

Cheers,
Steve

No, we mean at the boiler end, see edited photo

Thanks @CBW

Just been back through the setup instructions in the Tado app and it doesn't mention touching this block of wiring so it could be the issue.
Just power off an remove that yellow link cable?

Yes

They won’t, it’s in the boiler instructions, or if your an engineer.

Thank you! Sorted.
Wish I'd posted here rather than contacting Tado hours ago now.
