In my opinion, KONEs destination dispatch systems are the most stylish, and easiest systems to use available on the market. They're programmed very well, and the presentation is spectacular.
I don't really care too much about what these were before, I LOVE these destination dispatch MiniSpace EcoDiscs alot! And this is coming from a guy who is NOT a huge fan of KONE.
It's kinda hard to explain + I don't exactly know how it works. I believe that when group call is activated, you can allow a couple of lifts to come to a floor at once. It's probably there in case the lifts are being elevated a lot. Depending where you go, I think this feature may be locked with a PIN, probably to prevent people messing around with the lifts.
