How to associate a TRV with a specific thermostat (Dual Zone)
I've got two thermostats as my heating is dual zone. I've added the first TRV which seems to be working correctly and turning on the heading downstairs when it calls for heat, but now I am adding my second TRV but it needs to be associated with the 2nd thermostat upstairs. I've looked around the UI but I can't see where I can do this. Any ideas how I do this?

I only had a single thermostat when I installed the first trv
That said i now think that it’s the opposite of smart heating as it looks to turn on all thermostats when any TRV is asking for heat. This is the opposite of energy saving as you end up hearing parts of the house that are already up to temp/ don’t have smart trvs
You should be able to tell the system which zone to turn on for a smart trv to get heat0 -
The point of TRVs is that they locally sense heat and only allow heat to their radiator if needed. If they locally don't need heat the heat is not 'radiated' by that radiator both preventing that room from getting too hot and allowing the hot water to flow round your pipes to any other radiator that might need more heat.
In the case of a smart TRV it adds the ability to only tell the boiler to fire up if at least one smart TRV or Thermostat requires heat, if all the radiators are 'satisfied' then the boiler does not need to run.
So as long as all your radiators/rooms have smart TRVs then only the ones that need heat use it.
(Apparently you should always have at least one radiator not using a TRV so that your system can allow excess heat to radiate, this is often the bathroom.)
If you have your Tado setup defined so all the smart TRVs are listed as being in a single room then it may have linked them so if the 'master' sensor for that room needs heat all the others open as well.

I realise how TRVs work but I was expecting them to support multi zone (as in actual heating zones ) such that it doesn’t turn on all zones when only one needs it.
If the system only works efficiently if you have Tado TRVs on every radiator this is a limitation that should be made very clear. Anything less and your probably using more energy than without any smart TRVs and just using the smart thermostats.
I have 1 bedroom which’s often colder than the rest so wanted a Tado TRV in there which from various forum posts I think is a very common use case
(All my Tado TRVs are assigned to individual rooms)
I guess I’ll have to keep an eye on my bills and if they go up remove all the TRVs and just stick with the main thermostats. Time to raise a feature request0 -
Hello RobC,
For configurations with setups of more than one circuit (Smart Thermostats) at the moment you'll need to contact our support.
Please chat us at www.tado.com and we can help you.
Best regards

Same issue here. TRV in upstairs bedroom I’m second zone calls for heat but if master bedroom containing second zone thermostat is OK then no heat to the other room.0

The feature that you are after is very easy to have setup but you need to contact Tado. They set my 17 TRV, 2 Smart Thermostats and water extension up into 2 zones, Upstairs and Downstairs perfectly

Yes this setup (currently) requires Tado support to do the change for you. So the good news is that what is needed can be done but it is insane that it requires Tado support to manually configure this.
This is not the only example of a situation like this there are other similar scenarios that require getting Tado support to do the config for you.
It therefore seems obvious that the problem is that neither the Tado app nor a hypothetical method via a Tado website makes it possible for customers to do this themselves. The clear required solution is for Tado to add these features to the app. I can understand not wanting to crowd the app with esoteric features but that is what an 'advanced settings' option is for - for hiding esoteric settings. 😉
Please Tado save your support team from having to repeatedly deal with issues like this and equally user frustration and add the relevant settings to the app.

Which thermostat type did you have, wired or wireless for the TRV’s to be associated with?0
-
Is this still the case today?0
-
No, you can set the zone controller from the app now.1
-
So I have a zone controller and two wired smart thermostats. AIUI, To get heat going around the right pipes I need the controller to say the heating system is on and I need the right smart thermostat to then open the demand valve. The demand valve then opens and when it's open enough the microswitch in the valve engages and the boiler kicks in and pump starts.
It's not clear to me how the zone controller knows which TRV should be associated with which wired thermostat. The wired thermostat in this case just acting as a dumb switch to open the valve.0 -
I'm pretty sure I have option D on this https://support.tado.com/en/articles/4689126-how-does-tado-control-heating-zones-how-can-i-change-the-zone-controller-of-a-room0
-
@CaptSisko in the settings menu click on the room name for each TRV. At the bottom of the next menu there is an option to change the zone controller for the TRV.

Problem is the zone controller listed is only the wireless receiver. It doesn't list the other two smart thermostats0
-
It looks like the app has not installed the thermostats as the correct type. You can either go through the installation process again, following the instructions at the bottom of this page.
Or contact customer support and ask them to make the configuration updates for you.

Ah ha. That is a possibility, as I did first install the wireless version as I have hit water control too.
Thing is, I have correctly selected my thermastat model that I replaced so, do I have to "pretend" I'm replacing my heating control unit or do I lie and say I'm replacing the thermastat but wired to the boiler with Live/neutral?
It's been 24 hours now and no word from tado support.
Appreciate your help btw0 -
On the plus side this suggests that when I commission the second round of trvs I should be able to configure this myself rather than going through tado to configure (just acknowledge the two smart thermostats are zone controllers.0
-
Just to close the loop, support changed backend configuration and I was able to link the rooms.
I have another problem now but that's for another thread0
