Hello,

I want to create a central system to control my venetian blinds. Additionally (WAF), it should be possible to operate the control directly at the window as well. After thorough research, the best way seems to be to also allow manual control via the actuator (located in the basement/control cabinet). From there, a 5-core cable runs to each window/button. From the flush-mounted box, a 4-core cable continues to the motor.

In my understanding, the wiring would look as follows. The only concern I have is the parallel operation of the motor and the control line. In other words, when the blinds are moving down and the button applies 230V to the parallel line. According to initial research, this only happens for a few milliseconds and due to the motor’s design, no short circuit occurs.

...or are my concerns completely unfounded and is the installation, as shown in the picture, entirely correct?

Thank you in advance for your feedback,
Best regards
