Support dual parallel and sequential doors.
I have dual parallel ground floor doors, i.e. I can enter through two doors using a single Siedle BTS intercom
No advanced things here. If any intercom relay button is activated, the opener should react and be able to open preferably the specific door or alternatively all doors at the same time. Both in case of parallel and sequential doors (don’t really see a technical difference). I have heard this being supported on the competitor nello without issues.
