OR Function

Hello and sorry to be publishing in English here (there’s no reply elsewhere!).

I need the same light circuit, receiving comand from both ON (and separate OFF) and also a TIMED command (from Doorbird detector) to REMAIN ON, when the timed circuit goes OFF.
I just haven’t been able to find how to do it, since the OR function seems to only work with MOMENTARY command to a relay. There’s a Homecenter unit and I also didn’t make it work. I deeply appreciate any help here, please.

I’ve seen a lot more activity here in the Dutch zone and it’s somehow out of despair that I’m “trespassing” here.
By the way, what am I or should I do, to at least get someone to write ANYTHING?
Thanks, JJS
