Thank you a lot! I will try it and let you now the progress. I need some time to do it...

@Stuart-Middleton
Thanks. Of course, I can do these. I have Raspberry Pi B and other required things. What I need to know is a schematic of connections and what software to install (on PC, on Raspberry Pi...)

Again, Thanks a lot !

@Maciej-Jablonski
They are not selling any more this. (Their answer: The MAX! boiler controller has been withdrawn from the market due to poor customer uptake. We do not believe there to be any devices available in the sales channel.)

For a beginner, what shall I read (links) to understand what it means to do this. I have MAX cube and 3 actuators and I need a boiler control device. I called eq-3 and they reply they are not selling boiler controller device BC-TS-Sw2-WM (The MAX! boiler controller has been withdrawn from the market due to poor customer uptake. We do not believe there to be any devices available in the sales channel.) Thanks a lot !
