I have a tac20 that when I put it in sabbath mode it makes a full run up and down opens at each floor then when it gets back to the main landing opens doors closes them and stops. I don't know if it's a specific programming problem or what, only way to make it do a full run again is to either reset controller well it is still in sabbath or enter a car call, which kind of defeats the purpose of sabbath mode. Any help on this is greatly appreciated. As I am running out of ideas
