Hi,

I have two Eve Thermo. One is in use on an radiator previously fitted with a Danfoss RA as works great. The other I am trying to fit on an older floor heating system. The previous valve was a Danfoss RAVK. I used the RAV-adapter which fitted perfectly on the brass connector on the heating system. I fit the Eve Thermo on the adapter, but the calibration failed with the code E1. I tried the 2-cent trick, but still the calibration fails. I also tried deeper "adapters" between the valve pin and the motorised on/off switch in the Eve Thermo thinking the distance from the motor to the pin was too deep. Out of ideas now. Anyway to get this working with the RAVK?

Kind Regards
Henning
