High Efficiency
The RB Series is a high efficiency water source heat pump
in a compact vertical and horizontal cabinet. The product
features highly efficient and reliable single capacity rotary scroll
compressors mated with large blowers. These blowers are driven
by efficient 3 speed PSC blower motors, 5-Speed ECM blower
motors, or highly efficient Variable Speed ECM blower motors.
Quiet Operation
All RB Series product incorporates several noise reduction
technologies and is ARI 260 sound rated using third party sound
testing. Room Noise Criteria Curves (NC Curve) may be calculated
using data from the ARI 260 ratings giving the engineer total
flexibility in assuring a quiet environment. Please refer to the
separate Sound Ratings and Performance Catalog concerning this
standard and RB Series sound performance data.
Super Quiet Option
An optional Super Quiet Sound Package is also available for a
modest cost and features multi-density laminate lined compressor
blanket designed to completely surround the compressor and
suppress low frequency noise.
Indoor Air Quality (IAQ)
All units feature several IAQ benefits:
• Corrosion-free composite double-sloped drain pan to
eliminate standing water and prevent bacterial growth
• A washable surface on insulation in all air handler compartments
to allow cleanability and inhibit bacteria growth. Optional non-
fibrous closed cell insulation is also available for more sensitive
applications by special request through commercial sales..
• Open filter rail comes standard for non-ducted return
applications. Filter rail is field switchable from 1 in. to 2 in. [2.54
to 5.1 cm] for more filter options.
• Optional factory mounted, four sided, deluxe filter rack that is
field switchable from 1 in. to 2 in. [2.54 to 5.1 cm] is available for
ducted return applications.
• Standard supplied filter is a pleated MERV 4, 1 in. [2.54
cm]. An optional low static high efficiency 2 in. [5.1 cm]
MERV 13, for LEED certification points, is also available.
Flexible Control Options
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
satellite devices. The second channel is configured as a satellite for
connecting the Aurora Interface Diagnostic Tool (AID Tool).
The Aurora Interface and Diagnostics (AID) Tool is a device
that is a member of the Aurora network. The AID tool is used to
troubleshoot equipment which uses the Aurora control via Modbus
RTU communication. The AID tool provides diagnostics, fault
management, ECM setup, and system configuration capabilities to
the Aurora family.
