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
