I've recently moved into a new house fitted with Honeywell TRVs on all the rads.
The valves obviously have some effect, as I can turn the rads on and off with them, but there doesn't seem to be any adjustability, they're either full on, or totally off.
I would normally expect (as in other properties I've been in) that setting them at about "2" or "3" would be comfortable. But if I leave them at that setting, it's unbearable.
If I set the valves about half way between "*" and "0" if I leave the heating on too long all rooms become unbearably hot so evidently with the valves set (theoretically) so low, they're not working properly.
Is this because they have become "sticky" and I may be able to fix it by removing the tops and "exercising" the pins?
Or can they be adjusted somehow so the usable range is "0" to "6" rather than "0" to "*"?
