The whole system is balanced including the HW and i re-checked it after swapping the TRV's in case it upset anything. But even if the rads are completely unbalanced, when the TRV sensor head detects the room is at the correct temperature or above, it should shut and stop flow through the rad regardless what the valve the other end is set at as they are in series so either valve can limit the flow through the rad? If the rad was still hot when the room was 32C and the TRV was set on 1 of 1-5 what do the number relate to? Drayton say in their instruction that it has a range of 10C-27C so i assume 1 is 10C and 5 is 27C right? Also why does it matter how the radiator gives out its heat conduction, convection or radiation the result is still the same, the room is way too hot and the TRV seems to have no control over the room temperature.
