Johnson Controls has, through its YORK brand, expanded its line of premium commercial rooftop units now available in 25-80 tons with new, dynamic features. The expanded YORK Sun Premier platform is designed to offer contractors faster installation and simplified start-up, while providing building owners with best-in-class efficiency levels that significantly reduce operational costs over the life of the unit.
To simplify system configuration and minimize start-up time, units feature start-up wizards, a 5.5-inch OLED display and an optimized numeric keypad, which are standard on all units. This can be upgraded to the optional new high-end graphical user interface, which features a full-color touchscreen that provides quick access to system status, performance metrics and schedule parameters. Start-up is further simplified with the new RTUToolkit app for Android and iOS. With the app, contractors simply scan a unique QR code on each rooftop, which enables on-demand access to unit-specific details, technical literature and direct connection to technical support.
Premier rooftop units streamline the design process with integrated system selection tools, easily accessible building information modeling files, improved submittals and simplified specification. The high-performance base models offer a complete range of factory options. These include various airflow path configurations, indoor environmental quality options, such as ultraviolet lights, and modulating options for improved comfort.
Maintenance is also simplified with service-friendly features, such as an optional Mobile Access Portal gateway that offers remote monitoring for ease of connection while at the job site, allowing technicians to interface with units without getting out of the truck. In addition, the Smart Equipment-enabled units provide seamless integration with leading building controls systems, including Verasys, and with OpenBlue, a dynamic connected platform for smart, healthy and sustainable building solutions from Johnson Controls.
YORK Sun Premier commercial rooftop units meet aggressive Department of Energy 2023 energy efficiency standards. Offered in standard efficiency (up to 10.9 EER/15.8 IEER), high capacity or high efficiency (up to 11.4 EER/16.9 IEER), Premier units can provide up to 50 percent greater efficiency at part-load than is required, depending on the standard. Modulating options, such as compressors, an energy recovery wheel and gas or electric heat, further improve energy efficiency.
Premier units are backed by a one-year parts warranty, standard on all Premier units, along with either a six-month or one-year promotional labor warranty (versus the industry-standard, 30-day labor warranty) when started by a certified contractor.
