About this deal

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. 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. It has come to the end of it's life and now has to be reprogrammed after each power failure. To save expense (New programmer / rewire etc.), has anybody any information about the battery type or replaced one? We would rather not remove the programmer, have a look and then have to do it all again if possible. I had bought some TRVs as well but after reading some of the comments in here about them I think I'm gonna return the lot. Furthermore, the H21XL thermostat has a built-in frost protection function, which prevents pipes from freezing during cold weather. This feature is particularly useful for homeowners who often leave their houses unoccupied for extended periods.

Many thanks for this however as I said in my initial post I am working with just two smart thermostats and an extension kit. 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. 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. 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.May I ask how you are controlling each room individually? Do you have tado TRVs installed in each room or something? I can't see how it's possible without them. The thermostat is compatible with a wide range of heating systems, including gas, electric, and oil boilers. It offers basic functionalities such as temperature control, allowing users to set their desired room temperature and adjust it as needed. Horstmann are now known as Secure ControlsThe C27 CentaurPlus two channel heating programmer offers 7 day programming at an affordable price. What I have discovered the Smart Thermostats do not need to be calling for heat and can be set to Off, 24/7. You have a quote in your basket. We cannot merge this product with your quote. If you want to add this product to your basket your quote will be removed.

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. With a triple channel programmer, hot water control should just remain on that programmer. Just set the heating to "always on" for both heating zones. 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.Hot water, and 2 heating zones. I have bought Tado V3+ wireless thermostat (probably better will be wired kit ) with hot water control item 104005 (refurbished:) ,additional to that bought smart thermostat (wired). items M / C-Stat M 11 ThermoPlus AS2-RF 13 ThermoPlus AS1 / AS2 / PRT1 15 Time Controls 17 - 30 ChannelPlus 17 ChannelPlus H37XL Sep 26, · wiring diagram.

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. Smart thermostat is controlling zone 2 independently (valve 2). in the setting need choose Zone controller to None (work as independent).Sparky, that explanation is a great help for me thank you. Could I trouble you with a couple of follow on questions please? Afterwards, just replace the 2 wired thermostats with tado wired wall thermostats and you have full heating control with tado. 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. 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. And/Or is there a more energy efficient alternative for controlling heating and hot water in our context? Thanks
