confused by rooms and zone controllers

Morning all,

I recently installed a Tado X system and not sure I had set it up correctly. We have a large open plan area consisting of a sun room, a kitchen and a dining room. There are 4 radiators so I installed a tado X TRV. on each and a wireless temp sensor in the dining room.

I also have a lounge which stays significantly colder than the open plan area, so I have 2 TRVs in there.

I originally put each TRV from the open plan area into seperate rooms, but just discovered this morning that the coldest radiator in the otherwise warm open plan area was calling for heat and running the boiler.

So I've moved the 4 TRVs and the wireless temp sensor all into one room, called Downstairs. There is a second room, Lounge, with the 2 TRVs in there.

Both rooms have the Zone Controller set as the Wireless receiver. In the app it says All rooms that are controlled by these Zone Controllers are in the same heating zone.

I'd like the lounge to be able to call for heat independently to the open plan downstairs area, will this work with both rooms set to use the same Zone controller? On recent nights its been 17 degrees in the lounge and over 20 in the downstairs area.

Thanks in advance,

Greg

    @kitenski Hello. A primer on Tado-speak.

    1. First the 'zone controller' is the Tado device that is wired to your heating zone valves that turn the boiler ON and OFF. In your case that's the 'wireless receiver', with two channels for CH and HW.
    2. The TRVs and temperature sensors talk to the wireless receiver when they want to 'call for heat'.
    3. The chat is through your Internet connections and Tado servers, aka 'Cloud'.
    4. Your open plan room should be Room DOWNSTAIRS in the App configured with the four TRVs and wireless temperature sensor.
    5. Your other Room LOUNGE will be configured with two TRVs..
    6. Make sure you configure the Rooms with the Zone controller, The heating for your two rooms will turn ON and OFF 'independently'.
    7. The other setting 'No Zone Controller (independent)' means that the TRVs wil NOT call for heat. They act as a smart time/temperature TRV when something else calls for heat. This is more appropriate for small homes, or older boilers that do not modulate the heat output.

    8. Rooms with multiple 'X' TRVS take an 'average' temperature for the room. (Lounge)
    9. Rooms with 'X' TRVs and a temperature sensor, use the sensor for temperature measurement. (Downstairs).
    10. 'Suck it and see', the Tado sytem is very flexible. It took three months to figure out what worked well for us and how the comfort for each Room worked. Three years later we're still learning.

    11. E.g. if your Lounge is noticeably colder than the Downstairs AND your boiler does NOT modulate … configuring Room Downstairs as 'No zone controller (independent)' may be sensible option. Similarly, your large open-plan space may have colder spots? In which case there may be a better alternative by splitting the Tado configurations for Rooms.

    Hope this helps.
