Radiators stay on

Hi, I’ve got 4 SMART TRV’s they are on a scheduled cycle. When 2 of the rads hit the set temperature ie 20°c the room temp then exceeds this, but the TRV stays on.. shouldn’t it turn itself off? Any help on this.

    I am having the same issue with one of mine. I have even set it to frost protection but it is still heating up.

    I've had this problem and figured that the issue lay with the valve not being closed properly by the Tado valve head. In my case I have Myson type valves that use an adaptor - I had to swap the adapter pegs (provided) for longer ones (also provided). This fixed the problem. Have you also checked that the valve head is fully tight on the valve body - even a fraction of a turn could be the difference between the valve closing fully or not. Lastly, have you checked that the valves do close fully using your old thermostatic valve head?
    HTH,

    I an issue now where the boiler is still heating my rooms to 21° even when it's set to be off or a lower temp.
