I do understand you, it's my fault - I just explain too much.
Okay, I played as to where you where in the game.
1. Turn back to the control room and enter.
2. Adjust the center panel to alas tres (pointing right) and alas sais (pointing down).
3. Doing this down arrow at 6 o'clock position will now open the door that has the red button.
Good luck! - post again when you need us!
