ASTON INDOOR SPLIT SERIES INSTALLATION MANUAL
The Aurora 'Base' Control System cont.
Emergency Shutdown - Four (4) seconds after a valid ES input,
P2-7 is present, all control outputs will be turned off and remain
off until the emergency shutdown input is no longer present. The
first time that the compressor is started after the control exits
the emergency shutdown mode, there will be an anti-short cycle
delay followed by a random start delay. Input must be tied to
common to activate.
Load Shed - The LS input disables all outputs with the exception
of the blower output. When the LS input has been cleared, the anti-
short cycle timer and random start timer will be initiated. Input must
be tied to common to activate.
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.

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.
