I have bought 6 eve thermo. We replaced piping and valves for our house. Brand new valves are danfoas RA-N models. I get constant E1 calibration error. I tested these before piping work, we had danfoss ravl valves and only one radiator I was able to calibrate thermo at that time, didnt spend much time thinking this as new valves were coming. But now still e1 error from multiplw valves and thermos.
