BACnet Device Instance Number
By default, the BACnet Device Instance Number is generated automatically by the thermostat (Vendor ID + MAC address).
For example, Carrier Corporation vendor ID is 16, and if the MAC address is 075, the BACnet Device Instance Number is
16075.
Note: If you change the MAC address, you must cycle the thermostat's power to reset the BACnet Device Instance Number.
You can override the automatically-generated BACnet Device Instance Number using the i-Vu® application, an Analog
Network Output microblock in a control program, or some other BACnet utility. Write the new BACnet Device Instance
Number to the present_value property of Analog Value 42 (BACnetDeviceInstanceNumber).
