Okay thanks. But what I donā€™t understand is that this device is for Nefits ketel with Nefit Easy thermostat. To convert opentherm to Nefit ems technologie. And with plugwise Adam it is the other way around. Opentherm tot Nefit ems

The link States Met deze converter is het mogelijk om van uw OpenTherm ketel het protocol van gesloten naar open te zetten.

But my Nefit is not opentherm based it is on off

Hierdoor kun je OpenTherm thermostaten zonder problemen aansluiten op je Nefit of BOSCH HR CV-ketel. So from Thermostate to boilerā€¦

I used the same device to make my Nefit work with OpenTherm. The device is the key to convert your in/off boiler to OpenTherm.

Nefit are excellent boilers. But what a shame that they dont widely support openthermā€¦

I ran it on a 10 year old boiler. I needed to add the Easy Control Adapter AND the EMS to OT adapter. And this worked, but consumed a lot of gas. I did not have a on/off boiler.

Checked online and with the boiler-service company.

Replaced the boiler with an Intergas HRE. Now it workes like a charm.
