Hi, today I installed Wireless Smart Thermostat Starter Kit V3 + with Hot Water Control, I managed to connect them all to WiFi, the problem I have is that I can't change the hot water temperature using the application. My boiler is Vaillant ecoTECPLUS 831. How can I solve this problem?

    I didn’t think you could control hot water temperature with tadoº, just turn it on or off. Isn’t there a thermostat on your hot water tank that is still wired into the heating circuit that controls the relay too?

    How interesting @GrayDav4276. I must admit I skimmed over the combi bit. I went by the V3 kit and the installer instructions because I just installed one on a non combi system recently. They show how the receiver uses the cylinder stat for hot water temperature with a tank. In the case of a combi, the hot water control is not wired up. https://www.tado.com/start/manuals/st/Wireless%20Smart%20Thermostat%20Incl.%20Programmer%20with%20Hot%20Water%20Control%20Manual.pdf

    Didn’t know you could set hot water temperature remotely on a combi via the extension kit. Can’t do that on mine. The hot water is always on if you open a hot tap.

    I have the hot water tile, but it only allows me to set the schedule for it, not the temperature.

    The extension kit would have indeed replaced your old thermostat’s direct control over the boiler for heating. Tadoº can’t work without that, so you definitely needed it. I can only presume that your boiler permits electrical control of the hot water temperature. I’ve just never heard of that.

    Thanks @GrayDav4276. The boilers that I have experience installing tadoº on are all old, cheap or both. 🤣 None of them have that low-voltage control stuff that yours seems to. All part of the learning experience.

    Hi Gary this is exactly what I want to be able to do .I currently can’t. I guess I need to wire the canbus or low voltage. My installers said it couldn’t be done.

    Hi all

    #I have a s plan condensing boiler with a hot water tank thermostat. I had TADO fitted by a qualified electrician who replaced my old programmer with TADO. The hot water is very hot and i want to reduce the temperature. I have tried adjusting the original tank stat but it does not seem to make any difference. I have tried to use the TADO room stat but I cannot bring up any temperature to adjust fro the hot water the option is only on or off. In teh TADO app there is no option in teh hot water tile to adjust temperature of teh hot water only the scheduled times i.e on/off

    Looking at the wiring diagram in teh enclosed TADO instructions foro my boiler sytem and set up there is a connection between the tank stat and the TADO unit is it possible that it has not been wired correctly??


    Any help gratefully received
