AFFINITY SERIES OUTDOOR PACKAGED HEAT PUMP INSTALLATION MANUAL
The Aurora™ Control System
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. The ABC
features microprocessor
control and HP, LP,
condensate and freeze detection, over/under voltage
faults, along with communicating thermostat capability for
complete fault detection text at the thermostat.
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 slave devices. The
second channel is configured as a slave for connecting the
Aurora Interface Diagnostics Tool (AID Tool).

Description
Microprocessor control of compressor for timings with FP1, HP,
LP, Condensate, assignable Acc relay
Smart Grid, Home Automation Alarm Inputs, and Accessory2
Relay (HRV/ERV)
Compressor Contactor powers Loop Pump with inline circuit
breaker and no loop pump linking capability.
Control monitors compressor starts for high current, missing
leg etc.
Allows simple input to externally enable of occupied/
unoccupied mode for basic utility time of use programs.
Allows simple input to signal sump, security, or smoke/CO
sensor alarms from other home automation or security systems.
The two inputs can be field configured to a number of options
and logic.
Allows direct communication of the Aurora to Smart Meters,
Home Automation Network and Internet.
IntelliZone2 communicates Modbus to the heat pump via the
AXB board.
Communicates to the heat pump via 24VAC (AXB not required)
Aurora 'Advanced' Control
The Aurora 'Advanced'
Control expands on the
capability of the Aurora
'Base' Control (ABC) System
by adding the Aurora
Expansion Board (AXB).
The additional features
include compressor current
monitoring, loop pump
linking, and also allows for
optional energy, refrigeration,
and performance monitoring
factory installed add-on sensor kits.
The AXB also features a second
field configurable accessory relay,
and two home automation inputs that are AID
configurable for different types of alarms from
sump pumps to home security. The Smart Grid
input is AID configurable with many options to
react to Utility controlled relay operation for ON
Peak optimization. The AXB also expands the
communication capability for IntelliZone2 ready
operation as well as other expansion with the
ClimateTalk protocol.
