Introducing Energence® ultra-high-efficiency units.
We pushed the boundaries of
innovation to bring you our best
commercial comfort system.
With our latest innovation,
we have delivered the:
– Most Efficient
– Quietest
– Lightest
Rooftop unit in its class.*
Highest Efficiencies – Up to 13.9 EER and 21.5 IEER
exceeds
ASHRAE
standards by
Lowest Outdoor Sound Leadership – As low as 81 dBA
Technologies such as an advanced cooling system, DirectPlus™ blower system and
ECM outdoor fans help reduce outdoor sound levels.
Lightest Weight Leadership – Up to 42% lighter
New Energence units are packed with intelligent features such as the Prodigy® 2.0 Unit
Controller, yet are up to 42% lighter in weight than many leading competitors’ units.

Ultra-high efficiency, made possible
with ultra-high technology.
MSAV® technology
MSAV® (Multi-Stage Air Volume) supply fan technology is standard on all ultra-highefficiency models and uses five different airflow settings to automatically adjust
operating speed for a higher level of performance:
• Improved part-load efficiency: Up to 72% IEER improvement**
• Reduced energy consumption: Up to 83% supply fan power savings**
DirectPlus™ blower system
For new ultra-high-efficiency units, an MSAV option with a direct-drive blower
is available:
• Patent-pending design combines the motor and electronics into one unit, eliminating
the need for a variable-frequency drive for even greater performance efficiencies
• Fewer components and slide-out access help reduce maintenance time and costs
• Sound-reducing grille lowers indoor sound without affecting airflow
Advanced cooling system
A patent-pending cooling system with scroll compressors delivers industry-leading
performance throughout the year:
• Compressor configuration uses the coil system as a whole, rather than in parts, to better
match cooling capacity to demand
• Compressor compartment is isolated, allowing for easier access and servicing
• The Prodigy® Control System uses advanced algorithms to distribute the run time
between compressors during part-load operation, extending their lifetime
Prodigy® Control System
A smart idea that keeps getting smarter, the Prodigy Control System has more than
250 adjustable parameters to meet almost any design specification. New display
enhancements make monitoring and controlling the system easier than ever:
• Wider viewing area is designed for a more intuitive flow of information, and allows easy
access to the home screen from any point in the menu
• Help button with menu-specific content simplifies operation and troubleshooting
• Improved SETUP menu with dedicated guides for initial installation, building control
systems and air balancing
SunSource® Commercial Energy System
Units achieve an effective efficiency of 34 SEER, 43 IEER and beyond† when
integrated with SunSource® solar modules—a Lennox exclusive.
**At 55% airflow using the DirectPlus™ blower, when compared to full load belt-drive units.
†
Effective SEER and IEER estimates for the SunSource® air conditioning system are based on the U.S. Department of Energy
(DOE) annual performance factor (APF) method for heat pumps and air conditioners (10CFR part 430). Estimates of annual solar
energy production are calculated using National Renewable Energy Laboratory’s (NREL) PVWatts, calculated at tilt angle 10
degrees with an 180 degree azimuth. Estimates of annual cooling operating cost savings for the rooftop units are calculated
using Lennox’ Total Cost of Ownership Calculator, with operating hours from 10 am to 10 pm in a small retail environment in the
Omaha region. Estimated SEER energy calculations were made using Energence® LGH060H4E (5 ton/17 SEER 3-phase – 460V)
and six 275DC W solar modules. IEER effective efficiency calculations were made using Energence LGH094U4E (7.5 ton/21.5
IEER 3-phase) and seven 275DC W solar modules. Note that SEER and IEER equivalents may vary by location.
