I have some Mcquay units with bacnet cards. 2 separate buildings with 2 rooftop units on each jace. Sometimes it happens a few times a day and sometimes it will go days without happening. The units will drop out and just about when they ramp down, they will start coming back up. Im thinking i am losing comms for second and once it comes back it starts the units back up. When i check the change of state history extensions on the occupancy point, i see a fault around these times. It is happening on both jaces at different buildings.Is there any settings that i can change to prevent this from happening? There are only two units daisy chained on this bus so there should not be any issues with the comm line.
