Control General Description Application Display/Interface Protocol
Aurora Base Control The ABC microprocessor provides all the features
necessary to operate today's standard WSHPs that
utilize dual capacity compressors and Variable Speed
ECM/5-Speed ECM blower motors with hot gas
reheat. This control can communicate to a handheld
diagnostic tool to help the installing contractor or
service technician with equipment setup and service.
By utilizing Modbus RTU communication protocol,
the ABC board can communicate with additional
devices on the Aurora network.
Used for residential and commercial
applications that use single or dual capacity
compressors with PSC, 5-Speed ECM, or
Variable Speed ECM blower motors. This
base control can also communicate to the
AID Tool to display faults, inputs/outputs,
and software revision. Commercial features
such as hot gas reheat, slow opening water
valve, and random start are also capable
with the ABC board.
Optional AID Tool
can be used for field
service.

Aurora Base Control
The Aurora Base Control (ABC) System is a complete residential and commercial comfort system that brings all aspects of the HVAC
system into one cohesive module network. Aurora uses the Modbus communication protocol to communicate between modules. Each
module contains the logic to control all features that are connected to the module. The Aurora Base Control (ABC) has two Modbus
channels. The first channel is configured as a master for connecting to devices such as a communicating thermostat, expansion board, or
other satellite devices. The second channel is configured as a satellite for connecting the Aurora Interface Diagnostic Tool (AID Tool).
