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. So I can wire the extension kit, but could you explain what other configuration steps you took please? Horstmann Central Heating Programmer - Holiday Setting.

My first update was to replace my room stats with Smart Thermostats and the 3CH programmer with the Extension Kit. I had connected both heating zones to the same connection CH on the extension kit. Simple and straightforward. Need heat? Smart Thermostat would switch 'on' and the Extension Kit would switch on the CH providing power to the Smart Thermostat, in turn operating the motorised valve for that zone/ floor and then turning on the boiler. If the other Smart Thermostat did not request heat then that heating zone would remain off/ cold. If both did then all CH zones would get heat.

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. In my setup, I had 3 channel Programmer, hot water, ground floor CH1 and 1st floor CH2; each heating zone had a room stat; one in the hallway and one in the master bedroom. The diagram shows a link between the 2 stats but I hav no wires left. Does any one know if I should fit a bridging wire and i Horstmann C27 heating controller wiring. The H21XL thermostat features a clear display screen that shows the current temperature and settings, making it easy for users to monitor and make adjustments. It also offers programmable scheduling options, allowing users to set different temperature levels for different times of the day, ensuring optimal heating efficiency.I've a similar 2 CH zone+ HW system as you. I've installed 2 tado smart room thermostats in each of the zones. Final part is to replace the programmer with the extension kit to be able to control hot water. Tado have paused my online installation saying tado is incompatible with a 3 channel system. Like you I can see I should just wire both existingCH ON wires to the single CH ON terminal on the extension kit, and let the call for heat from the smart thermostats drive the zone valves and boiler. I've explained this to tado and asked for installation instructions based on an equivalent 2 channel system and wait for a response. The Horstmann ChannelPlus H21XL thermostat is a home heating control device that allows users to easily manage their heating system. It is designed to be intuitive and user-friendly, providing a convenient way to regulate room temperatures. Finally, when you do this yourself does the HW appear in the App? Tado have paused my my installation and I'm conscious I might also need tado to do something to enable my extension kit, that they might be reluctant to if I've installed against their guidance. 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!

I understand you have to configure hot water control on one of the thermostats?You mention you asked Tado to reconfigure the extension kit to remove CH? How did you ask please? I'm wary of switching off the CH ON line from the extension kit to the 2 thermostats. As long is it stays always on, I know that's fine as the thermostat will do the switching.
