The Aurora™ Control System - York YAFS012 Installation Manual

AFFINITY SINGLE & DUAL CAPACITY SERIES 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 Hot Water Generator Pump with inline
circuit breaker and thermostat limit.
Microprocessor and separate power relay for Hot Water Generator
Pump with digital temperature monitoring and multiple HWG
setpoint selection.
Compressor Contactor powers Loop Pump with inline circuit breaker
and no loop pump slaving capability.
Microprocessor and separate power relay for loop pump and inline
circuit breakers and loop pump slaving.
Capable of setup, monitoring and controlling a variable speed
flow center.
Control monitors compressor starts for high current, missing leg etc.
Coil temperature is monitored and air flow is reduced for maximum
latent moisture removal.
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.
IntelliZone requires traditional TStat inputs. IntelliZone2
communicates to the heat pump via the AXB board.
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 slaving, intelligent
hot water generator control,
variable speed pump
capability, 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.
