There have been various problems with 2.8.0 as UDI is reworking parts of the ISY and then updating the SHN device support on top of that rework. The last 2.8.0 build is about 2 weeks old and is stable as far as the SHN device support. However, I have not tested that image extensively for all the other ISY function. I would just move Zone 1 to one of the unused Zones for now. If you have the capability to run the SHN Utility Suite (PC with XP and EZSrve,PLC, or PLM powerline interface) it will change the Zone 1 timeout value. Since the ISY is not setting the Zone 1 memory location at all I would assume the new timeout value would remain intact.
