Weru front door with auto-lock + electric opener and Siedel video intercom system.

Good evening everyone,
my following concern is that a new Weru front door has been installed at my house which is equipped with Auto-Lock and E-opener.
This requires a supply voltage of 12V - 24V AC or DC with at least 2A supply.
Unfortunately, my new Siedel video intercom system only provides 12V DC with 1A supply.
I have now obtained an additional transformer with the appropriate supply voltage and supply current.
My problem is to connect the E-opener to my Siedel video intercom system.
I am attaching a picture here. (on the left the connection diagram for the Auto-Lock + E-opener and on the right the wiring of the Siedel video intercom system)
If my front door were only a normal E-opener, I could wire the Siedel exactly as shown in the plan, but since I need more power this is no longer possible. (bridge between Tö and b & c and Tö to E-opener)
My question now is: Am I correct in assuming that I can realize the depicted button (as shown in the Weru wiring diagram) by connecting the output of the new transformer (brown +) and the control line (black +) each to the two relay contacts of the Siedel power rectifier?
That would mean brown + goes to the upper Tö and black + goes to the lower Tö, and if you now operate the opener from the indoor unit, the switch should close and the E-opener should then receive its power and the lock will open.

Thanks in advance for your input.

Best regards

The wiring is actually not a big problem. However, you need an additional relay 12V AC. The door opener contact from the intercom goes to the coil A1-A2. Then, on the relay's switching contact, only the normally closed contact of the door as described in the plan.
