What does the self-test check after activating the module?

After activation, the self-test runs through each switched group separately: it checks whether the measurement works, whether the app signal reaches the correct group, and whether the switch actually opens and closes. The always-on group is checked for correctly remaining outside the switching mechanism. You see a tick mark for each group; if one is missing, you know before the first guest which group the installer still needs to check. The test does not check whether the wiring is logically distributed and does not provide continuous monitoring during guest stays.
