Had a new boiler replaced so the electrician came to wire the boiler helped me to install the Tado system (He never did Tado before). So we read the instruction and wired. Smart thermostat is controlling zone 2 independently (valve 2). in the setting need choose Zone controller to None (work as independent).

I am interested in the outcome of this as I have a similar system but with underfloor heating downstairs instead of radiators. F-Gas (Fluorinated gases) government regulations specify that a limited number of products can be sold in the European Union that contain F-gases which have been linked to climate change. Could I ask, are the Smart Thermostats in relay mode (wired) and not wireless? I'm guessing they are wired to a motorised valve which controls the heating zone. I feel so close to having the setup I wanted, and it's frustrating to see that tado will in fact support my 3 channel system, just that they don't realise it! The Heating zone controller is set to the Zone Smart Thermostat, for me 1st Floor. So when the Smart TRV calls for heat it will activate the Zone controller this then switches the motorised valve for that heating zone which starts the pump and boiler.

I have installed a wired Tado thermostat to replace an existing CH zone room thermostat but need to get the Tado V3+ wireless thermostat installed to replace the other wired thermostat (currently above an oven) for the other CH zone and ideally the hot water as well.

If you absolutely need hot water control with tado, we fully recommend you hire a heating electrician. This person should then "permanently bridge" both heating zones in the existing programmer.Sparky, that explanation is a great help for me thank you. Could I trouble you with a couple of follow on questions please? Attached is my current wiring. I am not good at Electric terms, here it's mentioned that we need to "permanently bridge" both heating zones in the existing programmer. However, I wanted more control. I've since upgraded all the radiators (9) with Smart TRVs. Tado Support setup Zones/ Floors, added Smart Thermostats and TRVs to their respective zone/ floor. Soon ran into a problem with the setup; asking for heat from a Smart TRVs on the 1st Floor would not turn on the boiler. My elderly mother finds the H37 XL confusing to use, also the buttons are now badly worn & requires a new device, is anything similar & easier to use without rewiring. Am thinking a 2 channel possibly.

The copy functions copies one days timings to another day. It was present on older models. See the manual for details.Why do you need to re-wire the upstairs? The Boiler control thermostat by default has to be 'calling for heat' for other devices to work but it is an easy switch (chatline - couple of minutes when connected) to make all devices capable of activating the boiler. I am concerned because I'm being told by Tado that it is not compatible. The only option they are offering is to keep my current programmer and use this in conjunction with their thermostats. If I do this I will not be able to control my hot water. As I said I currently use three channels and tado only supports two. Why are you concerned that a single bridge wouldn't cope with your house? Two floors and hot water is normally no problem. Do you currently have comms problems at home? What I have discovered the Smart Thermostats do not need to be calling for heat and can be set to Off, 24/7. We have an existing Horstmann H37 XL ChannelPlus on an oil-fired system. It has been in use for many years and works fine but changing the on/off times drives me nuts because each day has to be done separately. You wouldn't believe the number of button presses this involves. I note that the spec here says the timer has a Copy function? How does this work? Is this feature new or am I missing something on my old version of this timer? If this is a new feature I'd probably buy a replacement for this alone.
