The Lennox® Model L rooftop product line features the revolutionary Lennox® CORE Control System and
advanced variable-speed technology to maximize energy savings and comfort while providing the lowest total
cost of ownership in the industry. But that's just the beginning.

Take control of your humidity needs with advanced dehumidification technologies
With the addition of optional Humiditrol+, Lennox now offers an ultra-high efficiency rooftop line with energy
efficient hot gas reheat so that building owners don't have to choose between efficiency and humidity
control. Humiditrol+ is a modulating hot-gas reheat dehumidification system that reduces operating costs
while providing better indoor air quality and optimal building health under a wider range of indoor and
outdoor operating conditions. The Humiditrol+ system prevents overcooling and delivers premium comfort
while maintaining a discharge air temperature target. By modulating the compressor, indoor blower and
outdoor fan(s), we can deliver the required amount of dehumidification at the lowest energy level.

Leverage open integration with built-in BACnet
The integration and insights available from the Lennox® CORE Control System make it a solid fit for the
modern building. The Lennox® CORE Unit Controller offers integration with traditional thermostats, built-in
BACnet IP and MS/TP, and new wireless sensors, giving consumers flexibility. The unit controller's BACnet
interface features the most extensive set of available objects from a Lennox Unit Controller, and detailed logs
and reports provide clarity to system operation.

Install, start-up and service your rooftop all with the Lennox® CORE Service App
The Lennox® CORE Service App replaces a traditional built-in user interface on the Lennox® CORE Unit
Controller. The CORE Service App provides step-by-step guided setup menus for install, test and balance, and
network integration. Real-time data readout, enhanced test functionality, and multiple device support sets
the Lennox® CORE Control System apart from other unit controllers on the market. The service app facilitates
seamless commissioning of wireless sensors and sensor networks compatible with the Lennox® CORE Control
System. The CORE Service App was named a finalist in the software category in the 2021
AHR Expo Innovation awards.
