Hi everyone,
can anyone help me how to connect netatmo relay on boiler (Ferroli Bluehelix Tech 35C). I couldn't find something for this. https://www.manualslib.com/manual/14660 ... =50#manual

Re: Ferroli Bluehelix Tech 35C
Hi, take a look at page 14 of the manual.
https://www.manualslib.com/manual/14660 ... =14#manual
Connect the Netatmo Relais‘ brown and blue wires to the terminals marked 14 (brown) and 15 (blue).
Then remove the bridge wire between the terminals 5 and 6 (marked as „72“) and connect the Relais‘ black and grey wires to these terminals, polarity is not important.
Happy wiring

Look at page 34 and 39 here,

You have to remove the jumper of the “double” connector (72) and install the black and grey wires of the relay also if there is a jumper in A connector remove it. Terminals 14 and 15 are in use only in Bluehelix RRT models for external controls (i.e. secondary circulating pump).

Re: Ferroli Bluehelix Tech 35C
In the manual posted by the other user it says:
We will have to wait and see if the user returns for feedback.
So it should work with the Relais as well.NOTE - The terminals 14 &15 are 230v Live & Neutral to power an external clock if required (Optional extra)
We will have to wait and see if the user returns for feedback.

Re: Ferroli Bluehelix Tech 35C
I forgot to mention that Bluehelix Tech (25C, 35C) and Bluehelix Tech RRT (24C, 28C, 34C) are completely different boilers with different PCBs. So I thought that the manual that the user above used was the wrong one.
Re: Ferroli Bluehelix Tech 35C
Replacing „connection 72“ with the black/grey wires is the important part and that seems to be identical throughout the Bluehelix line.
And piggybacking the Relais‘ brown/blue wires to the power supply is always an option.

Re: Ferroli Bluehelix Tech 35C
I agree with you, the idea of the Bluehelix gas boilers is the same. But also it is very important to remove the jumper in A connector (If installed) because the primary function of the A connector is as secondary thermostat and if it is installed the boiler will always running.

Re: Ferroli Bluehelix Tech 35C
Thank you everyone who responded to my question. I got the information from you and I will let you know as soon as I did it. I cannot try now since there is construction ongoing at home.
