I have some of these TRVs (yes I know they are old and cheap)
I have an idea that it is possible to alter their range, i.e. if "4" cuts off the rad before the room is hot enough, or "1" is not cold enough, you can set it to a different temp) and I think I set some of them like that at installation.
However I can't remember how I did it, and there are no pins or adjustments that I can see in the head.
Does anyone know how it might be done?
