Good video! Nice selection of lifts! I think the extra button above the up arrow on the ecodiscs with the screens is to call the right lift only. The left lift stops at floor 5 but the right one continues on to 6 and 7. People for 6 and 7 will press that top button for the right lift so they are not getting the lift that only serves up to 5. That is what I think anyway as I know Kone do that set up sometimes as it was the same at Derby when I was there.
