I couldn't find a pdf of the user manual for this one but here is the link to a video manual:
2CHWith lock mode, prevents all relays from de-energizing due to dmx controller de-energizing and restartingIdeal for remote timing controlCustomizable delay time

This has now been added in the Crescit library, meaning the fixture will be available as of next Monday (18.07.22).
