Hello, thanks for taking the time to respond. I had taken the HR92 off, and had manually opened the valve. This evening, I replaced the hr92 head. It appeared to be turning, and went from valve 96% on insert to valve 0 after a while, but radiator was still on. I took the head off again and there was a fair amount of closing to do with the manual closure of the valve.

I am going to repeat the above again on stroke 1 to see if that helps
