BACNET® FIXED FUNCTION THERMOSTAT
5 31-00093—03
The Device Instance Number must be unique across the
entire BACnet system network because it is used to
uniquely identify the BACnet devices. It may be used to
conveniently identify the BACnet device from other
devices during installation. The Device Instance Number
is set using the installer setup menu through the device’s
display or over the BACnet network. The Device Instance
Number can be changed by the user, which may be
necessary when integrating with a third party or when
attempting to replace an existing device and it is desired
to maintain the existing Device Instance Number. The
factory default Device Instance Number is 0009999 and
can range from 0-4194302.
NOTE: The device instance can also be set over the
BACnet network.

Installer Setup (ISU) Codes
Installer setup mode provides access to functions specific
to installation of a BACnet FF. Some BACnet FF
configuration parameters can be altered from the ISU
screens. The ISU parameters can also be accessed via
BACnet.
A password (PIN) can be required to access ISU mode by
