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.

Hi, I am looking for an adapter to connect Eve Thermo to Danfoss RDR vent. Do you know what adapter shoul I look for? Thank you. Petr

Mar 16, 2022

Hello, we have 3 different sign types at our heating pipelines. 1st: “pi”-like symbol, F OV; 2nd: DN10; 3rd: DN15. Current thermoheads are Oventrop at all of them. Is it possible to know what adapters (if any) should I use to mount the Eve Thermo? Thank You very much!

Feb 6, 2022

Hello filip! It depends as ther are different valve types used by Oventrop. The new ones are M30x1,5, not needing an adapter. Older M30x1,5 fit but are not ready for thermostats with a motor. And a third group is M30x1,0 that always needs an adapter. You may need to ask a pro (plumber) . Best regards, Volker

Feb 6, 2022

Thanks, Volker. Can You tell me how do I identify the vent isn’t ready for motorized thermostat? Can I measure there some proportions to recognize current valve type and find the right adapter without hiring a plumber?

Feb 7, 2022

Hello Filip! The ones I know of (I have two in my own flat) Eve Thermo fits (M30x1,5) but can't be fastened. Best regards, Volker

Feb 8, 2022

Hello, I just would like to offer a solution for Oventrop 30x1,5 ventil owners which cannot tighten Eve Thermo at it (after fastening still loose). I developed a working adapter to be easily 3D printed and inserted between the thermo head and ventil. No problem to provide the 3D model via e-mail for those who are interested.

I have used Danfoss Living Connect thermostats and is now moving to Eve Thermo. For my radiators, I used this adapter: https://www.vvsobadrum.se/reservdelar/reservdelar-radiatorer/danfoss/danfoss-overgang-mma-m28-till-living-termostat. It's a M28 to M30 adapter. Will this work for Eve Thermo as well? I am concerned because when installed and calibrated, the radiators are way too warm, so my feeling is that it can't properly closde it. Do I need another adapter?

Jan 26, 2022

Hello Jonas! This may be ok, if the valve is an MMA, this is what the link says. These are the links I have for MMA

After calibrating the valve should close if you set Modus to off in the app Eve. Best regards, Volker

Hi Volker, I have 4 Eve Thermo's i am looking to install on Arroll Radiators and the link below is the valves that i need to get an adaptor for.
https://www.arroll.co.uk/products/50/uk28/antique-brass#model
I believe they are 28mm TRV valves but i cannot be sure.
Clearer images of the valves are here: https://imgur.com/a/UyBruoy
Any help would be appreciated.
Thanks Daniel

Jan 19, 2022

Hello Daniel! It is really hard only looking a valve photos. We have +70 valve types in Europe. The one in the link is not an adapter as far as I can see. What is the manufacturer printed on the old, manual thermostat. Best, Volker

Jan 20, 2022

Hi - I have just bought an Eve thermo to try out (I have 8 radiators waiting) and I have determined that my valve is a Danfoss RA. However, the adapter will not really fasten (even when I tighten the screw really really hard, the adapter can stil rotate and be taken off by hand. If I fasten the Eve Thermo onto the adapter, when Calibrating and just get an Error saying calibration failed . I can hear the Eve Thermo working when calibrating, first for a time, then pause, then failure notification and the it retracts I can hear.

What to do to debug the installation?

Jan 14, 2022

Hi, I'm Gianni from Italy. I bought Eve thermo in Amazon.it and, of course, She (?) doesn't fit on my Giacomini thermostatic valve so I only need an adaptor but: where to buy it? and which kind? I'm stuck.
Thanks, Gianni

Jan 11, 2022

Hello Gianni! I already answered your same question in Amazon Answers and in our support system. Please stick with one and don't double post. Thank you.
Eve Thermo comes with the standard M30x1,5 connector and adapters for Danfoss RA, RAV and RAVL. Giacomini needs an adapter:

Hello,

I got Eve Thermo for Christmas (yay!) but none of the adaptors fit my valve - I have uploaded an image here https://imgur.com/sIhBtMx

It's old, but not on/off valve as it has a valve now that I can set from off all the way to 5, so I am hopeful an adaptor might be available for this?

Dec 29, 2021

Hi, I've just fitted a new Eve Thermo to a radiator that previously had a Myson TRV 2 way. It fitted OK and calibrated. However the radiator is on heating up although the Eve temperature is set at 14.5 C and the room temperature is 21 C. Do I need to do something else. I am wondering whether the Eve plunger is touching the valve pin?

Dec 24, 2021

Hello Philipp, after adding and calibrating in Eve the basic setup has to be done:
How to set up Eve Thermo including the Offset

Important note: The temperature displayed below Target Temperature in Eve is measured by Eve Thermo way too close to the heater, please ignore it. Once an Offset is set, it will not be integrated here.

To set up Eve Thermo open the app Eve and goto
Settings > Accessories > Eve Thermo
Set Temperature Offset to 0 degrees.

Then in Eve goto Rooms > Eve Thermo and open Eve Thermo.
Set Target Temperature to 23 degrees for example and let it heat for 2-3 hours.
Then measure the temperature in the middle of the room with a thermometer, Eve Degree or Eve Room.
If it reads for example 20,5 degrees, goto
Settings > Accessories > Eve Thermo and set the Temperature Offset to -2,5 degrees.

You may have to adjust this over the next days a bit.
As stated before, the Temperature Offset is not taken into account in the temperature shown below Target Temperature.
Best regards, Volker

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

Nov 28, 2021

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

Nov 29, 2021

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

Dec 2, 2021

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

Dec 3, 2021

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

Nov 28, 2021

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

Hi,
I have a Westherm Four TVR, on a Comap value, and am struggling to find the correct adapter.
Are you able to advise which adapter I need. Thanks, Paul

Nov 23, 2021

Hello paul,
in case the Westherm is an M28x1,5, this would be the adapter you need:
Westherm M28x1,5 to M30x1,5

Hi,
My radiator has Danfoss RA-N (013G0013) valve. Does any of included adaptors is matched with it?
Bests,

Nov 13, 2021

Hi, Can these be mounted vertically?
Thanks.

Nov 12, 2021

Hello Juz! Yes you can and you may even want to flip the display. In Eve open Settings > Accessories > Eve Thermo > Installation and select Inverted. Have a great weekend, Volker

Nov 13, 2021

Is this compatible with the RA 2000 or would I need an adapter?

Nov 9, 2021

Hi Paul, I would guess you need an adapter, I do have this in my list, it's a germal URL, the only one I have:

Hi, I have just installed new radiators and as I can see, I have Herz valves installed. Can I use Eve Thermo on Herz Valves?
Thank you,
Mate

Oct 27, 2021

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.
We would like to buy a RAVL adapter
Thank You, Regards, Erika

Oct 8, 2021

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

Oct 8, 2021

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?

Sep 1, 2021

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

Dec 31, 2020

Hi! Is thermostat compatible with Purmo valves? https://www.purmo.com/en/products/panels/compact.htm

Dec 29, 2020

Hello Normunds! You'd need to check for the valve used there. Eve Thermo comes with a standard connector M30x1,5 and adapters für Danfoss RA, RAV and RAVL. Best regards, Volker

Dec 31, 2020

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.

Oct 14, 2020

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

Oct 15, 2020

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.

Sep 16, 2020

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.
Best regards, Volker

Sep 18, 2020

Hi Volker, i am going to install 4 Eve Thermo valves from Danfoss RA-N so you are saying they are not in the box? That part do i need to buy?
Thanks, Stefan

Mar 15, 2021

Hello Stefan! Eve Thermo comes with the standard M30x1,5 and we provide adapters for Danfoss valves RA, RAV, RAVL. The RA-N valve needs a different adapter, only have a german URL here:

Hi Stefan,

Did you try eventually? I did, and the included RA adapter did actually fit the RA-N valves.

May 18, 2021

I have purchased 7 of these eve-thermo's 2 of them fit my floor level radiators without issue however the thread on the wall mounted radiators and the full wall bathroom radiator they dont the thread is too big if I use the smallest of the 3 adapters then the thread is too big

Sep 5, 2020

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 [email protected]

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.
Best regards, volker

Sep 2, 2020

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.

Dec 30, 2020

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 !!!!

best

Aug 30, 2020

Hey Mark, glad it worked, I was pretty sure it will.
This just happens.
I wich you a great start into the week, Volker

Aug 31, 2020

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?

Aug 29, 2020

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.

Aug 30, 2020

Hi!

Where to buy this adapter?

Argo

Jun 9, 2020

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
