Spent all day on this. I've connected as per Tado instructions. The white light comes on when heat is required but the boiler doesn't fire. L to Ls, N to Ns. Grey to Lr. Black not used. Nothing happens with or without the jumper between Ls and Lr . I've tried with and without the built-in programmer attached. When attached, I switch it to ON. What am I doing wrong?

    You can use the desktop version of the forum to post pics of your wiring. Might help here as that sounds pretty standard.

    I don't understand how this all fits together. I get that the when heating is required, the white light will light up on the receiver and the relay clicks on . how a single wire completes the connection I dont know! And a jumper between live and Lr? Baffles me! I'm sure someone here understands all this

    Have you set the wireless receiver up for a combi? Look at section 6 https://cdn.brandfolder.io/607DGEMS/as/tqh86npbjjhws5gwkxfncbfh/104172-DIGITAL-WRP01IB01-INSTALLER_MANUAL-TA-UK-00-V2.pdf

    Yes, the link is to the standard installer instructions that come with the kit. As far as a I can tell, I've wire it up correctly, as per photos. The hot water light does not turn on, the relay is inoperative. The yellow light tells me I'm on CH only. I might have got it wrong. Is my wiring correct?

    As far as I can see your wiring is fine. Maybe someone else with more experience of your boiler can give advice.
