The OpenHR20 project aims to replicate the functioning of the TRV, and I
believe includes PID control, I've not looked at the code in any detail

Assuming PID control, it would be interesting to see whether optimal tuning parameters could be obtained using this method; fully opening the radiator from cold and measuring the room temperature over time. Possible problems here would be the slow nature of the system and the number of external factors (doors/windows being opened, objects being relocated within the room). A correctly tuned PID loop should achieve fast response with no overshoot.
