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, variable
speed 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 RS485 net (P8) connector on the
ABC control board.
