The RG Series cont.
Control General Description Application Display/Interface Protocol
Aurora Base Control The ABC microprocessor provides all the features
necessary to operate today's standard WSHPs that
utilize dual capacity compressors and variable speed
ECM/5-speed ECM blower motors with hot gas
reheat. This control can communicate to a handheld
diagnostic tool to help the installing contractor or
service technician with equipment setup and service.
By utilizing Modbus RTU communication protocol,
the ABC board can communicate with additional
devices on the Aurora network.
Used for residential and commercial
applications that use single or dual
capacity compressors with PSC,
5-speed ECM, or variable speed ECM
blower motors. This base control can
also communicate to the AID Tool
to display faults, inputs/outputs, and
software revision. Commercial features
such as hot gas reheat, slow opening
water valve, and random start are also
capable with the ABC board.
Optional AID Tool
can be used for
field service.
Standalone
FX10 The FX10 microprocessor control is a self-contained
control featuring LP, LOC, HP, LWT, and condensate
overflow fault modes that can be displayed on a
BAS system. Optional handheld Medium User
Interface (MUI) Control can be used for additional
setup or servicing. Program customization is
possible. This control is suited for both single and
dual capacity compressors as well as PSC and
variable speed ECM blower motors.
Commercial applications using single
and dual capacity compressors
with either PSC or variable speed
ECM blower motors. Also suitable for
multi-compressor products. Cannot
be integrated with centralized building
automation systems. Software can be
customized for specific projects.
Optional Medium Use
Interface (MUI) can
be used as a field
service tool.
Standalone
FX10 with N2 FX10 control functions as both unitary heat pump
control and DDC communication. Therefore, detail
operational and fault information is available to
BAS. Other features are the same as FX10 with
addition of Johnson Controls N2 compatibility.

Due to communication speed, no more
than 30 units should be connected to a
single trunk of the network.

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. 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 Diagnostic (AID) Tool.
FX10 Control
The optional FX10 control provides unparalleled capability in
several areas including performance monitoring, humidity, energy
management, and service diagnostics, and then communicates it
all thru standard DDC protocols like N2, Lon and BACnet (MS/TP
@ 19,200 Baud rate).
The most unique feature is integrating the FX10 into the RG Series
as both the heat pump and DDC controller providing both a cost
advantage and providing features not typically found on WSHP
controls. This integration allows heat pump monitoring sensors,
status and service diagnosis faults to be communicated thru the
DDC direct to the building automation system (BAS), giving building
supervisors detailed and accurate information on every piece of
equipment without removing an access panel!
