Hi,
Can you give my the right instructions for installing wireless?
Wires 3 and 4 are from my wired thermostat.

thanks Michel

Hi,
The last post on this subject was on March 2016. It's 2022 now and I am installing a Modulating Thermostat with the Nefit Ecomline. Same picture as added by mdurivou at the start of this topic. Ok colors are a bit different. I connected the Grey and Black wire to 3 and 4, Modulating or?? But that doesn't work, no activities from the boiler. Switched wires, still no response. Connected the Grey and Black wire to port 1 and 2 and the boiler started heating. Question: Is the the right way to connect the Modulating Thermostat? It's now connected to a on/off port??
Thanks for your support

I took your post out of that 6 year old topic and created a new one in the correct forum 😉


I believe Nefti Ecomline boilers don‘t support OpenTherm natively, but there seems to be an adaptor for that.

Thanks for your reply GEORGzer,
Before I bought the Netamo Thermostat I did a check on check.netatmo.com The Nefit EcomLine HR Excellent was compatible ??
Strange.
The link towards "comwo.nl" indeed tells me that my boiler uses a iRT protocol. Pffff
Should have know that before.
Anyway I will dive into it.

I just run the compatibility check and your boiler is compatible with the Netatmo Smart Thermostat. It looks like the compatibility check is only eligible for the Smart Thermostat ( Orange ) not for the Smart Modulating thermostat ( Green ).

Correct,the modulating Thermostat works a an one/off switch. The available adapters aren't usable.
The iRT protocol of the Nefit isn't supported. To old.
