Aurora ‘Advanced’ Control Features
The Aurora ‘Advanced’
Control system expands on
the capability of the Aurora
‘Base’ Control (ABC)
by adding the Aurora
Expansion Board (AXB).
All of the preceding
features of the Aurora
‘Base’ Control are included.
The following control
description is of the
additional features and
capability of the Aurora
advanced control.
It is highly recommended the
installing/servicing contractor obtain
an Aurora Interface and Diagnostic
Tool (AID) and specialized training
before attempting to install or service
an Aurora ‘Advanced’ control system.
The additional AXB features include the following:
AXB DIP Switch
DIP 1 - ID
: This is the AXB ModBus ID and should always
read On.
DIP 2 & 3 - Future Use
DIP 4 & 5 - Accessory Relay2
: A second, DIP configurable,
accessory relay is provided that can be cycled with the
compressor 1 or 2 , blower, or the Dehumidifier (DH)
input. This is to complement the Accessory 1 Relay on
the ABC board.

Compressor Monitoring
The AXB includes two current transducers to monitor the
compressor current and starting characteristics. Open
circuits or welded contactor faults will be detected. A fault
will produce an E10 code.
IntelliZone2 Zoning Compatibility
(Optional IntelliZone2 Communicating Zoning)
A dedicated input to connect and communicate with the
IntelliZone2 (IZ2) zoning system is provided on P7 on the AXB. The
is a dedicated communication port using a proprietary ModBus
protocol. An AXB is required. Consult the IntelliZone2 literature for
more information. IntelliZone2 should be mounted indoors.
AWL – Aurora Weblink (if available)
(optional accessory)
AWL is an add-on WiFi router that connects to the ABC
and offers many features:
•
Remote access to thermostat settings, schedules, etc.
with your smartphone, tablet or laptop
•
Receive Lockout/Fault info via text or e-mail
•
View heat pump energy usage from the Internet for the
day, week, month, year or real-time
•
Internet AID Tool capability allows remote
troubleshooting for the technician
•
Remote AID Tool capability at the heat pump with
smartphone, tablet or laptop for the technician
•
Allows data acquisition of the heat pump through
the Internet, see graphs of performance and chart
historical data for the technician
•
Stores historical data on SD card
NOTE: The AWL should be installed indoors and the
Ethernet cable supplied with the AWL should be run inside
conduit to the outdoor unit and connected to the ABC P8
(RS485 NET). Cable should not be in conduit that includes
high voltage wires. If the cable supplied with the AWL is
not long enough you may purchase standard Cat6 Ethernet
cable locally or order our part number 11P951-01, 100' Cat6
cable. The maximum Cat6 cable length should be kept to
150' or less.
Advanced Communication Ports
Communication ports P6 and P8 will provide future expansion
via dedicated protocols. These are for future use.
Smart Grid-On Peak (SG) Input
The 'On Peak' input was designed to allow utilities to utilize
simple radio controlled switches to control the On Electric Peak
behavior of the Heat Pump. With a closed contact signal, this
input will limit the operation and thus the power consumption
of the unit by one of the below selections. The AID Tool will
allow configuration of this input for the action of:
• No Action
• Disable compressor operation until removed
• Go to On Peak thermostat settings until removed
[Requires Com T-Stat] (Future Release)
• Compressor limited to low cap until removed (Future
Release)
• Disable compressor operation for 1/2 hr (can be
removed immediately) (Future Release)
Then Flash Code 7 on the Green LED for the 'On Peak' mode.
And On Peak will display on communicating thermostats.
