Aurora Interface and Diagnostics (AID) Tool
The Aurora Interface and
Diagnostics (AID) Tool is
a device that is a member
of the Aurora network.
The AID Tool is used to
troubleshoot equipment
which uses the Aurora
control via Modbus RTU
communication. The AID
Tool provides diagnostics,
fault management, ECM
setup, and system configuration capabilities to the Aurora
family of controls. An AID Tool is recommended, although
not required, for ECM airflow settings. The AID Tool simply
plugs into the exterior of the cabinet in the AID Tool port.
