TRV not calling for heat

Brand new install into an old house that I've recently moved into. Our Boiler is the garage, connected to an extension kit. Thermostat is in our kitchen, with two TVR radiators (TADO). All radiators else where in the house have Tado TVR - configured into seperate rooms / zones with single TRV / Radiators. All online and connected.

The TRV in a lounge doesn't appear to be able to call for the heat source - It only gets heat if kitchen requests heat. I thought this may be a questionable plumbing loop, with it connected off the kitchen (adjacent rooms). To test the theory I have taken the TVRs off the kitchen RADS so naked pin is available which if I understand correctly means the rads should be free flowing and activated if any TADO requests heat. Is this a good assumption?

I find this difficult to troubleshoot. Is there any way I can see application logs to see what TADO thinks its doing?

Is there an activity log I can see - I'm troubleshooting at the minute by activating various rooms to ensure each one can demand heat, but its slow going.

  • @samd, thats interesting, wasnt aware of that, what setup do you get by default or does it all depend on what setup you start with? Ive got extension kit next to boiler and assumed my TRVs were calling for heat when needed, but now you say there is 2 ways of working im wondering what ive got and what the benefit of each is. Is there any write up on this anywhere?

    @Adzyp In November last when I installed tado, I hit upon it by chance during a session on the chat line and once we confirmed what each of us was talking about (!) it took less than a couple of minutes for them to change me to 'all devices have primacy'. Never seen it written down anywhere and I have posted similar to my response above to newbies who did not know, many times over the last couple of months - it is clearly not in the 'welcome pack'

    Thanks for the help, support have changed the mode to allow all TRVs to call for heat. I'm not in a position to test but I'm sure this would fix the issue.

    Like you've said I can't see this sertting / default posture in any documentation. The whole point in me choosing this system over a competitors was the TRV heat calling option per zone.

    I feel that the documentation / settings / application could be updated to show the consuming how it is configured. I could have saved my self some time and effort turning valves on and off. No bid deal but the status could be clearer.

    Thanks again, and thanks to tado support.

    Am I correct in saying if you have an extension kit and all devices can call for heat then you are limited to 10 rooms (max 7 devices per room)?
  • Had exactly the same issue when I installed. This is only something that tado support can change. No idea why

    I wonder how many of these they have to do each day? ...

    I don't really understand why the default setup would be to work like a traditional thermostat when their website gives the impression that multi zoning is a feature out of the box.

    @digitaldr Not sure but thought the 10 room limit applied to any type of tado installation.
