Sounds like either the adapter is not fitted correctly (quite hard to get wrong though), or try the valves are faulty.
I don't rate Danfoss valves much, but I'd be surprised if they all were duff.
This kind of fault often has a simple solution, but one needs to see it with one's own eyes.Kind Regards - Dan Robinson (Jennings Heating Ltd)

Originally posted by willdonal View PostHello folk, I had the Honeywell evohome system fitted a few days ago. The problem I have is when any of the 14 radiators demand the heating to be switched on, I turned some up to see if it all worked, then all the radiators come on even though the rest of the HR92 radiator controllers are set to 10. In fact yesterday when I switched the water on to boost the temperature via the app, again all the radiators came on. Then to cap it all off when I switched the heating off via the app it stayed on. I had to switch it off via the wireless relay box. Everything is bonded correctly as far as I can be sure, I can set a certain radiator to say 22 on the evohome controller and when I check that radiator it is reading 22. Is this a wiring up problem, a bonding problem or a boiler problem. Thank-you in advance
If all else fails then try changing one fo the values with a Honeywell one (assuming you have generic valves at the moment).

The adapter has not been fitted far enough down on the valve body - it’s easy with Danfoss valves to think the adapter collar is fitted correctly when it’s not (you should not see a gap between the valve body and adapter when fully seated).
Undo the screw on the adapter, open up the adapter where it splits, and it will drop another few mm down onto the valve body, which is the correct position. You should then find the actuator can shut off the flow to the radiator.

Originally posted by willdonal View PostHello basiluk, I have the adaptor fitted as far on the valve as possible and screwed up to an inch of its life. Then the inners of the HR92 are screwed on to the adaptor again very tightly done up. The body of the HR92 just pushes on to the other bits with a push and click the locking mech. I will speak to the heating engineer on Thursday to see if the danfoss valves need replacing with a different type. thanks :-) :-)

Hopefully SH is there as well as me 😘. He's more experienced with this 5hsn most of us in the field.
You still have to tell is how long you are waiting before drawing conclusions to reaction events (or lack of).
Manual interventions with this stuff does upset it. One of the things I try and make new owners understand is that it is supposed to be quasi autonomous.Kind Regards - Dan Robinson (Jennings Heating Ltd)
