TADO X - support cannot set water temperature

Hello everyone, I installed my first Tado X kit with thermostat yesterday, set in Opentherm mode. As I have read in the forum, many complain about the fact that it is not possible to manually set the water heating and domestic hot water temperatures in the tado APP. Obviously my boiler doesn't allow me to set these temperatures if Opentherm is enabled (the thermostat has to do it), and this is what Tado support replied to me:

Hello,

unfortunately with tado° X we do not have the possibility to set the flow temperature.

In addition, with tado° X it is not possible to control the domestic hot water.

it is possible to make both changes directly from the boiler.

Best regards,

I'm starting to strongly doubt the quality of the product, also because I'm not a beta tester but I'm an end user.

    Hello @EmmettBrown 🙂

    Thanks for posting.

    I see that you also opened a ticket with our support team. I will re-iterate what was shared there so other members of the community can stay in the loop:

    At the moment, tado° cannot guarantee that the domestic hot water and maximum flow temperature setting functions will be implemented with tado° X, but we can confirm that they are both being evaluated in hopes of implementation for next winter (2024/2025).

  • We have now added the Opentherm Flow Temperature setting in the app for tado X.

  • Great news! But i can’t find the indicated menu in the last version of the app, is it still in beta?

    No, it's live as far as I know. But looking at your account, it seems like your thermostat X does not have an Opentherm connection anymore since August 16th. Opentherm (and, currently, tado X) is required for this feature.

  • thanks now it works! the sanitary water temperature is missing and then the product would be excellent.
  • The domestic hot water temperature cannot be adjusted when connecting the thermostat in OpenTherm mode. This prevents me from setting the water temperature, which remains at 60 degrees, this is dangerous for the family. Please give me an answer if this critical issue is being managed in the r&d department.
    I remember that when Opentherm is active, no parameters can be set in the boiler.
  • Same here... there's no 'Flow Temperature Optimization' option in the app, as was shown above.
  • Same here, my boiler hot water (not heating water, I am speaking about the water that comes out from the tap to be clear) temperature has always been set at 45 degrees. Once I connected Tado X thermostat with OpenTherm that temperature got set at 60 degrees and cannot be changed from the boiler. Please provide an option to disallow tado X from being able to change the boiler hot water temperature as 60 degrees is dangerous more than uncomfortable. Apart from that Tado X seems a great product from my first hours of usage...
  • @Rob kindly awaiting an answer for the hot water, we continue to have the water that comes out of the tap at 60 degrees. dangerous! it is necessary that you integrate an adjustment for that setting in the app as well. Thankyou

    @EmmettBrown Noted. I know it is on our internal roadmap, so planned to be developed, but I cannot give you any guarantees about if/when it will be implemented. I will use comments like yours to try to convey the importance when we prioritize how we spend our development resources.

  • @Rob I also share the urgency of @EmmettBrown as I have water coming out of taps at 60 degrees and a small child who is at risk of opening hot water by mistake...thanks for listening to us and prioritizing!
  • @GiovaF I have a two year old myself, I can relate. I cannot promise you a quick result but I will try to get this prioritized.

  • have you made any changes to the domestic water temperature? Now it seems like it’s limited to 43C or so. Is the issue present with all boilers connected via opentherm or only a small subset? How come the devs haven’t fixed such a critical issue, when it was reported two months ago. Why do you release a half finished product and want the full price for it? Unbelievable
  • From the information I gathered speaking with different people in the field this is not completely Tado's fault in the sense that every boiler seems to behave differently when it comes to OpenTherm connections, so it's very difficult to manage from Tado's side. Still, it shouldn't be too difficult to come up with an option sooner or later to change this parameter of the boiler's setting that Tado is clearly modifying, either remotely by support or directly by the user.

    I dunno they could’ve predicted the users will be pissed off. I don’t think it’s the best strategy in the long run. If it’s the case that they indeed can control it remotely, they could at least unblock the feature for the boilers they can handle atm

    Hi. I’ve just installed Tado x wireless starter kit to replace nest gen 3. I could set the maximum water temp (from the tap) with the nest but can’t find any option in Tado x. The Tado is connected to opentherm exactly as my nest previously was.

    It’s critical that I can set the max tap water temperature. I see the flow temp option but it doesn’t seem to affect the tap water temp. Please help. Small children burning themselves here.
  • Hi, just ordered my Tado X for our refurbishment project, I also have a toddler and am extremely concerned by the comments in this thread. Currently considering returning my system (due to be installed tomorrow). Please advise when this feature will be implemented, currently it means the system is unusable.

  • Just had this response from support:

    Hello, 

    thank you for your patience, your inquiry has just been transferred to me.

    I am sorry for the late response, we currently have a higher number of inquiries than is usual.

    One of our engineers was able to apply a new firmware to your devices and set the Domestic Hot Water temperature to a limit of 55°C.

    This feature is not yet available via the app, but it will be coming January (2025). once that is rolled out for everyone, you'll be able to set a Domestic Hot Water target in the app directly.

    Best regards, 
    Christoph

  • I am a bit new to this game, sorry for dumb questions.

    Will this new feature (hopefully Jan 2025) allow me to set boiler flow temperature for a system boiler?

    Do I need to put the Rad Stat into opentherm mode for this?
    How do I put a thermostat into opentherm mode?

    Thanks, Mark.

  • There are two different temperatures you can typically set from your boiler: flow temperature is the temperature of the water that goes into your radiators. Domestic hot water temperature is the temperature of the water that comes out of your sinks/taps. Here we are talking about an issue for domestic hot water temperature.
    Opentherm is a communication protocol between your boiler and your thermostat that allows you in principle to control these two settings from your thermostat. To have opentherm, your boiler must be compatible with the protocol and the wiring from your boiler is slightly different, depending on the brand and model of your boiler. Now, if your Tado is connected to your boiler on OpenTherm you are already able to control flow temperature and this feature works pretty nicely, at least from me.
    The issue here is that domestic hot water temperature cannot be controlled from the Tado app (yet) and for some boilers there is an issue with the OpenTherm communication between Tado and the boiler that consists in Tado setting the domestic hot water temperature to the maximum temperature (60 degrees for my boiler). Also, Tado overrides the boiler settings so that I am not able to set this temperature from my boiler. It's nice to see that for someone support has been able to fix the issue remotely. @SteveTaylor can you confirm that this actually worked on your boiler? It would be nice to know whether this can be done also for me and the other people here that are concerned for the safety of their children.
  • This has been fixed for me today, the hot water control feature has shown up on my app 👌
  • I saw that they have inserted the option in the HOME tab (as always in the changelog nothing is specified about this upgrade). Tried it and it DOESN'T WORK, set the temperature to 39 degrees, the water comes out at 60 degrees. I also tried restarting the boiler but the problem persists.

    I hope they report this SERIOUS problem at least with an email to all opentherm users and that they insert a warning on the site, they are sponsoring a product that DOESN'T WORK for months, and we are used as beta testers, on a product paid at full price. There are the terms for a nice class action on this product.

    @Rob I demand that all users be notified that Opentherm is not a currently supported mode for TADO products and enabling it is dangerous. You have been warned. I advise you to report it to your management immediately.

  • After reading the above I decided to test mine. I set the temerature to 35 degrees and ran the water. The temperature was indeed reduced as I could hold my hand under the running water. However, as the water continued to run, it cooled. It soon became barely lukewarm. Perhaps 35 is too low for the boiler to maintain. I'll do some more testing tomorrow with a thermometer and set more realistic temperatures.

  • No thermometer yet but I tried again at 41 degrees. Water ran up to hot and seemed about right but as more time passed it cooled again, althought not as much as when set at 35. Seems like something not right at the moment with this.
