Connecting Ospel Two-Key Shutter Switch: Somfy Programmer Replacement, Cable Connections & Wiring

Question

Dear forum users, Recently, the Somfy programmer from the external roller shutter has broken down. Unfortunately, the new one costs PLN 350 and for now I have to postpone such an expense definitely. In its place I would like to mount the Ospel two-key switch attached in the photo. Unfortunately,...

Are you sure that the yellow-green wire (from the blind) was not used?

I dare to doubt it.

I could use the model of this Somfy driver and the connection method. This would make sure which wire was used for it. According to me, the blind wire is missing one vein or the yellow-green was used incorrectly but this could confirm a picture showing the connection of a damaged Somfy controller or at least a description of the connection.

Otherwise, without checking how the blind is connected (without opening the blind or measuring) I would not risk any connection.

You are right - the yellow-green from the blind could be used. A network ground wire is tied with a knot.
I cannot determine exactly how the cables were connected in Somfy. The service has left the Somfy programmer loose and the cables protruding from the can. They came to two blinds - in the end I decided to fix one and the other I had to let go because of the costs and the fact that the cheapest connector / programmer was Somfy for PLN 350 for the price of the material.
However, they determined that it was definitely a programmer, because they connected the blind to the electrical outlet and worked.
The programmer, which was Somfy Crhonis Uno / Memoris Uno.

Generally it is like this:

Zero (power supply) should be connected to zero of roller blinds (it should be blue - I emphasize strongly: it should (!) Because I don't know how it is). The connection can be made outside of the switch (in the previous version it was connected to the "controller" because this one required power).

The phase (power supply) passes through the switch and is alternately fed once into one cable from the blinds, once into the other.

The problem is that some "fern" (because it was definitely not an electrician) laid the wrong installation and there is a 3-wire cable (including one protective one) from the roller shutter switch and it should be 4-wire (including one protective).

Because the "fern" ran out of veins, he decided to use the protective conductor (yellow-green) in an unauthorized way (or assumed in advance that he would connect it). Now it is not known what this yellow-green wire running to the blinds is supposed to do - whether it is to serve as "zero" or as "opening attempt" (phase).

I have already written above that without obvious evidence or measurements I would not dare to connect anything and before that I would take care of improving the installation.

[EDIT]
Terminals 1 and 2 are the same, as well as 3 and 4, and 5 and 6 (they are "shorted" in pairs). As a consequence, the switch has only 3 terminals and you can connect 3 wires there. Question - which one?

Thank you for the message - I am almost convinced that the yellow-green wire from the blind was used as a phase - opening control. I would conclude that the network ground wire is tied with a loop. I guessed that the blue cables should be connected. So it would appear that the blue next to this connector would have to be connected outside of it, while: - brown power supply put in 1; - brown blind in 3; - green-yellow blind in 5 (assuming that it is used as a vein). Am I right? In addition, the service, which was in the case of two roller blinds, connected them both to the power supply using clamps connected to the roller shutter cables in a box on one side and on the other there was an ordinary plug, which they inserted into the socket. There was a switch in the middle of the cable that made the blind close / open. Which in my opinion would confirm that the yellow-green from the blind is a vein and not an earth ground.

I don't know - it's just guesses. You can see how the other one is connected, where after the markings on the controller you will learn what function the wires from the blinds perform. Still, they will be guesses. It would be best to open this (first) blind and see how it is connected. Even if you make sure, the installation still needs improvement. [EDIT] Guesses refer to the color of the wires and guesses apply separately to the place of connection (I did not find the description of Ospel) although you are right in principle.

I just checked the second switch (because in the second place I have a one-button switch up / zero / down) and actually the blue ones are connected with a cube outside of it, while the brown network and brown from the blind and the yellow-green from the blind are connected to the switch. There is no additional vein.

So it is confirmed that it was done by someone without knowledge of art. I dare to doubt it

You are right - it would be easier for me because other manufacturers have either good diagrams on the Internet or more default markings on connectors. Thank you very much for your help. Tomorrow I will try to test the hypothesis in practice .
