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.

ABC Control Board Layout

Aurora ‘Base’ Control LED Displays

These three LEDs display the status, configuration, and fault 
codes for the control. These can also be read in plain English via 
the Aurora AID Tool.
