Some radiator thermostats are not taking control
Hello,
With the amazing help of @Montage and @wateroakley i managed to install the main controller of V3+ Wireless Smart Thermostat with starter kit and programmer with hot water.
I now installed the radiator thermostat on 12 radiators. 8 work well, but 4 of them continue to heat the specific radiator when the app is set to be turned off.
In other words, if one radiator is on in another room (for a good reason) these 4 join regardless of the thermostat and the app that indicates it should be off.
Here is what I tried so far:
1. Remove from the app and reinstall
2. Remove the batteries, re-calibrate
3. Check connection with the app (ask it to blink - say Hi).
For 2 of the 4 I had an initial E4 error, but the steps above it fixed it.
Pictures below for one example. Radiator. The manual valve I had before did work.
Any tips? Advice? More information that I should share? Thank you!

@NickUK If the radiator continues to heat …
- Use the flat blade of a screwdriver to check that the TRV valve pin moves freely down and up.
- Check which end of the rad is the flow and return. Look for the 'arrow' markings on the valve for a bi-directional valve, or an older uni-directional valve. Uni-directional valves will not work properly on the return.
- Check that the Tado TRV base is screwed fully down.
- Take the batteries out of the Tado TRV head. Leave out for at least one minute. Re-insert the batteries, refit the TRV and it should recalibrate.
- Check the Room settings for 'Independent' or 'Zone controller'. Note the V3+ control limit of 10 Zones and 25 Devices. With more than 10 'Zones', you will set some Room and Device as 'Independent'.
- To check the Tado TRVs, swap the non-functioning Tado TRV for one that you know works.
HTH.
