Replacement of Terraneo intercom with Comelit 2638

I just moved into a new apartment and the intercom doesn't work. I can open the door, but it doesn't ring. It's an old Terraneo, but I'm not sure which model. I bought a Comelit 2638 to replace it, but I can't figure out how to connect it. The Terraneo has six wires: 3 identical light blue, one dark blue, one yellow, and one white. The Comelit manual is incomprehensible. Here's what it says:

Terminals for connecting the system:
L L - Connection to the bus line.
CFP CFP - Local call input.
P1 C1 - Terminals for the P1 C button. NO. 24 V 100 mA dedicated to various services
(remove CV1 and CV2)
S+ S- - Terminals for the call repeating device.

Can someone explain to me what I need to do? Are the two models compatible?

Thanks in advance,

MariaTeCCM

    Hello....

    "nobody" because it's not really a forum for that, but well...! ;)
    Do you have the documentation:

    Thank you for your response. Yes, I have the documentation. That's where I copied the wiring that I included in my message.

    I thought this forum was precisely to ask how things work...

    Well... yes, but especially regarding computers...
    You should try www.cyberbricoleur.com, it's more the place.
    Good luck!

    It is unlikely to work, the Terraneo is probably a 5-wire analog intercom, while the 2638 is a 2-wire bus intercom (digital if you prefer) specifically dedicated to Comelit installations... so... absolutely incompatible with yours.

    Why didn’t you replace it with the same intercom as the original Bticino?
