Eve Thermo Adapter
Mar 30, 2019 - by Volker - Comments
Like other thermostats, Eve Thermo comes with a standard M30x1.5 connection for your heater’s valve. In addition, the box contains RA, RAV and RAVL adapters for Danfoss heaters. Eve Thermo can easily be connected to over 90 percent of all radiators without requiring any type of adapter. Only those who have very old radiators in their homes or who use unique solutions require adapters to connect Eve Thermo to their radiator valves.
Those looking for a suitable adapter to connect Eve Thermo to a very old or rare heating system can find information on valves and adapters at Energenie UK, Heating Controls Online or Conrad UK.
Eve Thermo is made in Germany by EUROtronic, which specializes in heating controls.

Hello, I'm planning on fitting the Eve Thermo to another radiator and it has 1/2 written on it and also F-8164. I can't tell what company the valve is from but the logo looks like the pi symbol. Which adapter would I need for such a radiator please? Thank you, David- Reply
Hello David! In case this is an on/off valve as the other you have, it needs to be replaced by a plumper. We recommend betting ist replaced with a valve that hast the standard connector M30x1.5. Best regards, Volker- Reply
Hi Volker, I had a plumber come today to look at my radiators. He said he could change the joints for me to M30x1.5 but he said it wasn't guaranteed that the Eve Thermos will work with the radiators even after that. I don't know why he said that, he didn't seem to be a fan of smart thermostats. I'm not sure if he had encountered Eve Thermos before.Is there any reason why the Eve Thermo wouldn't work well with our radiators after we change the joints to M30x1.5? Our heating here is collective, so the water is the same temperature for all of the building (apartment block). I think the thing that controls the temperature is the amount the water that flows through the radiator, and that's controlled via the screw tap on each radiator. Thank you, David

Hello David, as most modern thermostats als almost all smart thermostats use M30x1,5 valves it is a clever move to get tehm replaced. Best regards, Volker- Reply
Hello, I have a radiator valve with "SAR 1/2" written on it. I understand this radiator company is old and now Euromap Comap now makes the valves for it.Here are two photos of the valve, one of the photos has a small metal adapter that I currently have on the radiator. I'm not sure of it's function but I can take it off:
https://imgur.com/a/cUPWZYq
There are two threads. The largest screw thread is 29mm and the smallest thread is 19mm. The distance between the end of the largest thread and the tip of the valve is about 3cm. The nut on the metal adapter I removed in one of the photos is 2cm in diameter. I measured all of that myself so it might be a millimetre or so off.
If you know what I need to get to fit the Eve Thermo on I'd appreciate the info! And also, in my photos you see the valve I've got. Do I need to take that off at all? Or does the adapter I will buy just fit on top of that?
Thank you, David

Hello David! Thanks for the photo. You need to get the valve replaced with one suitable for Thermostats. The one you have is not it is just an on/off wheel. Best regards, Volker- Reply

Hello Mate! Yes you can, but you will need an adapter as Herz valves have M25x1,5 and the standard is M30x1,5.The following will fit;

Hi Volker, We have bought an EVE THERMO Smart Radiator Valve, Apple HomeKit (Chipset 2020).I would like to ask you where can we buy adapter for this kit.

Hello Erika! An adapter for Danfoss RAVL is part of the adapter set we ship Eve Thermo with. It is the small adapter without a screw to fix on the left hand side. Best regards, Volker- Reply
Hello there, I have an old radiator that im trying to fit the adaptor in but it's too big for it.The drayton TRV (BS6284)that I've taken out is 28mm and too big for the Eve TRV. I have tried the attachment but it doesnt fit. Any idea which one i need to buy?

Hello Shehzad Mohammad! The provided adapters are for Danfoss valves RA, RAV and RAVL only. Drayton needs another adapter. The Drayton TRV 4 does not need an adapter at all, your seems to. Are you sure it is 28mm? I only found one that comes with M27 x 1,0? You may want to contact me at [email protected]Best regards, volker

Hello,I have issues fixing the thermostat.
My current thermostat has an M28x1.5 connector from COMAP.

I tried every adapter I found in the box and I can't make it fit with the Eve Thermostat.
Do you have an adapter for M28x1.5 ?

Hello Yannick! The adapters provided are for Danfoss RA, RAV and RAVL only. You need an Adapter M28x1,5 to M30x1,5. I only have a URL for the German store, but you should find it where you live.https://www.amazon.de/Heimeier-Adapter-Thermostate-M28x1-M30x1/dp/B00VEA3R1Y

Hello,I just bought 4 Eve Thermo (Second generation) and tried to install them on my heaters. I am using a M30x1 to M30x1.5 adapter from Oventrop (bought on Amazon.de, metal version, should be the first listing at the top).
Eve Thermo starts calibrating, you can hear the valve opening and closing but it always fails at about 75% of the progress bar giving me a „general installation error“. Resetting did not help either.
Any ideas that could get these things running? I can provide pictures of my heater when needed.

Hello Dominik!This should not happen if the adapter is the correct one for the valve on your heater. Are you sure the adapter you got is the correct one? What was the manufacturer name on the old manual thermostat? You may want to contact me by mail at [email protected] to not open an ongoing thread here. Best regards, volker

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.- Reply
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.

Norbert, Your valve can't work with connected valves as it seems to be an old manual one which must be opened/closed by turning the button by the hand. That kind of valves must be replaced by thermostatic ones.- Reply
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?
- Reply
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.

Hi!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
