Lennox Landmark Rooftop Unit Line
Lennox Landmark high-efficiency models can reach up to 12.7 EER and, with optional MSAV (multi-stage air volume) supply fan technology, up to 14.5 IEER — making these units 27 percent more efficient than standard models (Part load, IEER improvement. Comparing standard 10.9 IEER system to optional MSAV 13.8 IEER system).
The addition of the Environ Coil System on all 7.5- to 25-ton
gas/electric and electric/electric units provides increased reliability and
sustainability, while the BACnet option ensures seamless integration with the
most popular building automation system protocol.
BACnet is offered on all Landmark units and provides connectivity to a wide range of capabilities including: control of the building’s heating, cooling and humidity levels as well as lighting, outdoor signage, refrigeration, security systems and other vital functions. The factory- or field-installed BACnet option is equipped with a BTL-listed device that ensures seamless integration with BACnet systems, giving the customer peace of mind. BACnet’s plug-and-play format also helps customers save time and money on installation and service by eliminating the need for expensive tools.

Environ increases the reliability and sustainability of the unit.
