Setting the Controller Number
Each controller on a network must have a unique
number on the subnet where it resides in order to
identify it in the Controller Configuration Tool (CCT)
for uploading, downloading, and commissioning.
The controller number is set using three rotary
switches (Figure 7) and may be numbered from 000
to 999. The numbers are ordered from left to right,
most significant bit (MSB) to least significant bit
(LSB) when the controller is oriented as shown in
FAC4911 physical features .
In the following figure the switches are set to
4 2 5, designating this controller as controller
number 425. The controller number must match
the controller number defined in CCT under Define
Hardware > Network Settings . The number of
the controller can be written in the white squares
provided so the controller number can be easily
seen from a distance.

Numbers
Note: The BACnet device ID is calculated
using the value of controller number added
to 2000000 . The device ID configured in this
manner does not require any configuration
from CCT.
