How do I mount the adapter for Danfoss RA radiator valves to fit my Smart Radiator Thermostat?

Please ensure that you only tighten the screw just enough for the adapter to remain on the valve and for the thermostat to be mounted. When correctly installed the two top parts of the adapter should be completely level with each other, as shown, there should not be any overlap or unevenness.


For some production batches of this adapter made out of grey plastic we have identified a minor manufacturing issue, these may not meet our normal quality standards.

If you are experiencing issues with grey Danfoss RA adapters we can send you a replacement adapter. Request a free adapter replacement for your Danfoss RA valve.
