Adapter für Eve Thermo
Mar 30, 2019 - Von Volker - 12 Kommentare

Eve Thermo kommt wie andere Thermostate mit dem Standardanschluss M30x1,5, dazu liefert Eve die Adapter RA, RAV, RAVL für Danfoss-Heizkörper mit aus. Eve Thermo lässt sich an über 90 Prozent der Heizkörper ganz einfach anbringen. Nur wer sehr alte Heizkörper zu Hause hat oder seltene Lösungen einsetzt, benötigt einen Adapter, um Eve Thermo mit dem Ventil des Heizkörpers zu verbinden.


Wer nach einem geeigneten Adapter für die Verbindung von Eve Thermo mit einer sehr alten oder seltenen Heizung sucht, wird unter anderen bei Eurotronic fündig. Eve Thermo ist übrigens “Made in Germany by EUROtronic“, das Unternehmen ist der absolute Spezialist beim Thema Heizungsregelung.
Alternativ lassen sich geeignete Adapter bei ELS finden, eine Übersicht gibt es bei eQ-3.

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.

Hello Tero!
For a RA-N valve you need a special adapter to M30x1,5. No way using the provided ones, they are only for Danfoss RA, RAV and RAVL.

Hello Shane!
Please check for the brand name printed on the old manual thermostat. It will give you a hint what adapter is to be used. You may also contact me at

Hello! I would like to ask if eve thermo is compatible with this radiator valve? Or do I need to replace the valve?

Hello Tóth!
I don't know any adapter that would fit here. I would gon for a new valve at best with the standard M30x1,5.

Hi Volker,

thanks, this did it!!!

actually all I needed to do was step 7+8

This situation happened with three valves. Worked and calibrated last year, not this year...

Nice work around.... I was slowly thinking I needed other adapters....

Anyway thanks a lot !!!!

I had Eve thermo working last year, now the batteries were dead so I replaced them. Now it will not calibrate anymore...

What to do?

Hello Mark,
Please try the following step-by-step procedure including the trick with the 2 cent coin. We have recently learned that around 10% of the valves used in Germany have a slightly too small stroke, the coin compensates for this.

1. Delete Eve Thermo from Eve app
2. Un-mount Eve Thermo and make sure that you can move the valve on heater side (if not use grease and eventually hit the valve's body with a hammer to solve the problem)
3. Put new batteries in Eve Thermo ("Er" means either calibration problem or discharged batteries)
4. Press one of the arrow on screen until "Er" disappears (the screen will then show "no", which means "mounting" and the valve will move to a correct mounting position)
5. Hard reset Eve Thermo until the 66/99 appears on the LED.
6. Re-pair Eve Thermo in Eve app and follow instructions to mount it and calibrate it.
7. Insert a 2 cent coin into the valve holder of Eve Thermo.
8. Follow the assembly and calibration instructions.

If the code ER does not appear on the display of the Eve Thermo during step 4, please skip this step.

Where to buy this adapter?

Hello Argo!
Depends on the valve the heater is using. Most customers search at Amazon or other places. You need to search for M30x1,5 and the valve name you have. Best regards, volker
