No heating upstairs!

Hi there.
Only just getting round to putting the heating on this year,

All of the radiators are coming on downstairs, but none of the radiators are coming on upstairs!

I have no idea how to deal with this on the app, there does not seem to be any way to sort it out using my mobile phone.

What the hell is going on?
And how can I fix it?


  • What Tado appliances are installed, how are they installed, do you have a combi or system (with hot water tank) boiler. You can post pictures of the wiring using the desktop version of the forum.

    Is this a new fault ?? 🤔 .....did you have tado° last winter, and did it work properly before.
    Or is this a recent installation.......
