NUKI OPENER - TE TONNA INTERCOM Ref. 641800

Dear All,

I am writing here in the forum because I have some issue to connect in a good way the cables of the Nuki Opener for my Interphone: TE TONNA INTERCOM Ref. 641800.
In some old discussion I have found that the cabling is similar to the Interphone Elcom HAT-402.

In fact following the instruction of the Elcom HAT-402, the Nuki opener is working well but the microphone to speak with the people downstairs is not working anymore.

Would you be as kind as to help me with the connections? Do you have the same issue?

I have 6 cables coming from the building and only 3 were connected.

  • 1 Light Blue to the number 6 (number written on the connector)
  • 1 Light Blue and 1 Blue to the number 5 (number written on the connector).
    I have 1 spare yellow, 1 spare light blue and 1 spare white.

Here below the current connections copied from the Elcom HAT-402 instructions (below the picture):

  • I have connected to the number 5: the Light Blue (existing) + the Nuki Cables (Red, Orange and Purple)
  • I have connected to the number 6: the Nuki Cables (Green, Blue and Black)
  • I have connected to the Nuki plastic connector: the Light Blue and Blue cables that were in the number 5 + The Nuki Cable (Yellow)

Thank you very much for you help.

Best Regards
