Hi, I want to install a smart radiator thermostat. Unfortunately, my radiator doesn't have the usual M30x1.5 thread. Do you know what kind of adapter should I buy?
It looks like Danfoss RA (RA-N with preselection to be precise, but that’s irrelevant for the adapter). To be sure, measure the outer diameter of metal ring with the four notches. It should be 23 mm.
When looking for an adapter, make sure you choose on that is suitable for “Ventilheizkörper” (radiator with integrated valve). Some adapters for this type only fit properly on separate valves outside the radiator.

Looks like a Danfoss RA-N, I guess.

Finding an adapter should be easy.
