Setting the BACnet
®
Device Addresses
11. “Set the rotary switch address on all unit controllers.,” p. 19.
12. “Ensure no duplicate rotary switch addresses exist on a BACnet® MS/TP link.,” p. 19.

Total Number of Trane and Non-Trane Devices on a BACnet
®
Link
15. “Limit the quantity of devices on a link when there are both Trane and non-Trane devices on the link.,” p. 20.
16. “Populate BACnet® links evenly when 30+ devices are present.,” p. 20.
