"S-Class rooftop units have been designed for applications that require low lifecycle costs, excellent indoor environmental quality, and superior comfort. Optional variable air volume supply fans, R-410A refrigerant, integral energy recovery wheels, and high-static power exhaust fans make these units ideal for a large variety of building types," said Mike Walker, product manager at Lennox.
The Integrated Modular Controller (IMC) aids both installation and troubleshooting work. It is built to control over 200 unit functions. Other features of the rooftop unit include quick-connect plugs, slab coils, coil cleaning access doors, and removable drain pans. Additional features include hinged access panels, step-in blower compartments and full perimeter base rails.
