    What is the controller? When you do the install you’ll get instructions in the app.

    It’s the tado wireless receiver that connect to boiler. Instructions in app aren’t clear as to which wires go where

    You might need to post pictures of your wiring (use the desktop version of the forum). If it’s a combi and relay connection it’s usually L, N, COM and NO. You should be gas safe if you’re opening up the boiler.

    You’ve broken the combustion seal so you should be gas safe or use a gas safe engineer. I would check what your boiler manual says but at a guess it will be L to A , N to B, and COM and NO to 1 and 2. That’s purely guesswork based on the sticker you’ve posted though and can’t guarantee it’s right.

    Johnnyp78 I’ve wired like you suggested but the radiators don’t heat up! Any ideas. Everything works like power to the receiver and when I press test it triggers the boiler on but the heating doesn’t work. Any ideas.

    Do you have Tado trvs? If not it’s a problem with your boiler.

    If you don’t have Tado trvs and the wireless receiver is triggering the boiler when you press test, it’s a problem with the boiler.

    I think at this point it’s time to get a professional in to check your wiring.

    Yes, but I’m not a professional and I have no knowledge of your boiler other than the wiring diagram I’ve seen.
