ᐅ The actuator remains closed and no longer allows the pin to move upward.

We are slowly but surely becoming frustrated. It was supposed to be a simple replacement of a faulty actuator. So we bought a new actuator, swapped it with the old one, and connected the blue and brown wires. However, as soon as we attach the new actuator, it pushes the pin fully down, blocking the flow. Although the two wires are connected correctly, the actuator does not allow the pin to move back up, and the blue part of the actuator is not visible.

We are now wondering what could be causing this.

Thanks for the idea. However, all the drives are normally closed (NC).

Then the RTR simply closes the loop because it was probably open continuously, and the room is currently too warm... once it cools down, it will work properly again.

The room probably cooled down last night. Currently, the left half of the room, which has its own circuit, is warm, but the right side is ice cold.

I would suggest measuring with a multimeter to check if the actuator is working correctly, meaning whether there is voltage at the terminal or not.

The actuator has pushed the pin down, the blue edge at the top of the motor is not visible, and there is no measurable power.

Because there are quite a few cables inside the junction box and space is limited, I connected the replaced actuator using a terminal block. Could this possibly be the cause of the problem?
