Aurora Advanced VS Control
Aurora Advanced VS
Control System is a
complete residential
and commercial comfort
system that brings all
aspects of the HVAC
system into one cohesive
module network. The
Aurora Advanced VS
Control features the
Aurora Base Control
(ABC) and the Aurora
Expansion Board
(AXB). The InfiniSpeed
drive communicates
to the Aurora Control
and provides variable
capacity and envelope
control. The ABC
features microprocessor control and HP, LP, loss of charge,
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 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).
The Aurora AXB expands on the capability of the ABC
control board. The additional features include active
dehumidification, SuperBoost cooling mode, loop pump
slaving, intelligent hot water generator control, variable
speed pump capability, and also allows for optional energy,
refrigeration, and performance monitoring 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.
Aurora Control Features
Description
Aurora Advanced VS
Advanced Microprocessor Features
Smart Grid, Home Automation Alarm Inputs, and Accessory2 Relay (HRV/ERV)
•
Advanced Hot Water Generator
Control
Microprocessor and separate power relay for Hot Water Generator Pump with digital
temperature monitoring and multiple HWG setpoint selection.
•
Advanced Speed Pump Control
Microprocessor and separate power relay for loop pump and inline circuit breakers
and loop pump slaving.
•
Variable Speed Pump
Capable of setup, monitoring and controlling a variable speed flow center.
•
Active Dehumidification
Coil temperature is monitored and air flow is reduced for maximum latent moisture
removal.
7 Series Variable
Speed Only
SuperBoost
Allow the variable speed compressor to ramp up an extra 30% of cooling capacity if
needed. This extra ‘SuperBoost’ will only be available for a 24 hr period and then the
unit will revert to normal operation.
•
Smart Grid/Utility Input
Allows simple input to externally enable of occupied/unoccupied mode for basic
utility time of use programs.
Dry Contact x1
Home Automation Alarm Input
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.
Dry Contact x2
HAN/Smart Grid Com
(AWL and Portal) Kit
Allows direct communication of the Aurora to Smart Meters, Home Automation
Network and Internet.
Optional AWL
IntelliZone2
®
Compatibility
IntelliZone2 communicates to the heat pump via the AXB board. IntelliZone requires
traditional thermostat inputs and is not compatible with the 7 Series.
Optional IntelliZone2
Service Device
Description
Aurora Advanced VS
Aurora Interface and Diagnostics
(AID) Tool
Allows setup, monitoring and troubleshooting of any Aurora Control.
NOTE:
Although the ABC has basic compatibility with all Aurora, new product
features may not be available on older AID Tools. To simplify the basic compatibility
ensure the version of AID is at least the same or greater than the ABC software
version.
