Figure 77: Addressing completed
This facility makes it possible to reset an addressed actuator in the case of a
replacement, repair, or if addressing is wrong (wrong address assignment by the user).
For that purpose, you need to press the actuator’s addressing button for at least 10
seconds when the actuator is in normal operation. The actuator will then reset its
address which is indicated by the LED, which is steady on.
