Trying to get I-vue schedules to run AHU's with 6400 controllers. Using global schedule 65 in the i-vue settings and it works for two of the units. Other two units do not respond to a change in occupancy. I've checked the 6400 programs and they are all setup the same in the schedules. Also have a packaged unit that is running on schedule 88...which it says to use in the help file of i-vue. This works great for packaged unit, but the 6400 schedules do not go up that high. Have double and triple checked for any discrepancies that could be causing a conflict, but I can't seem to find anything. Any help would be greatly appreciated.
