Communication - Bacnet - Carrier 09FC020 Installation, Start-Up And Maintenance Instructions

Communication - BACnet

See Table 15 for a list of BACnet Points.
Addressing the controller may be done with or without power.
Each time power is applied the controller reads the address.
Address is set using rotary switches. Set the Tens (10's) switch to
the tens digit of the address, and the Ones (1's) switch to the ones
digit. See Fig. 39.
Example: If the controllers address is 25, point the arrow on the
Tens (10's) switch to 2 and the arrow on the Ones (1's) switch to 5.
The factory default setting is 00 and must be changed to success-
fully install BACnet communication.
See Table 16 for required BACnet configurations.
