Good day, i have a trane RTAC375 chiller which after binding devices, when the chiller is running it will shutdown and come up with so many devices comms loss alarm, after I try to bind all the devices again I then run the chiller, after 2-3 minutes of coming up it will shutdown with comms loss alarm.
Other alarm is Excessive ICP comm loss, comms loss starter module compressor 1A, comms loss starter module compressor 2A, comm loss: oil temp compressor 1B and so on
