Aurora Interface and Design (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
variable speed ECM airflow settings.
