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.

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).
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.
