@fishypets: there is also a function to load the settings back in ProfiLuxControl, of course, otherwise it wouldn't make much sense to save the settings...
is under menu "File"

@antipodes: yes, there is a EEPROM, all settings should remain after a power cut
your suggestion is good - fishypets should do his settings again and then make the test: unplug/plug the power and watch what happens
but before - do the firmware update
