Johnson Controls and its TempMaster brand recently expanded its line of premium commercial rooftop units, which is now available in 25-80 tons. The TempMaster Omni Premier platform is designed to provide building owners efficiency that significantly reduce operational costs over the life of the unit. The units offer the highest standard efficiency levels in their class and meet aggressive Department of Energy 2023 energy efficiency standards.

“Our engineers achieved exceptional energy efficiencies with the new Premier platform,” says Todd LaMalfa, director of sales, Ducted Systems, independent rep channel, Johnson Controls. “This future-forward design allows the platform to deliver up to 50 percent greater efficiency at part-load than is required, depending on the standard, and additional options are available for each tonnage to meet the current Consortium for Energy Efficiency highest tier ratings.”

Units are 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). Standard double-wall foam panels offer improved thermal efficiency, while modulating options, such as compressors, an energy recovery wheel, and gas or electric heat, further improve efficiency.

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. The units have an optional high-end graphical user interface featuring a touchscreen that provides quick access to system status, performance metrics and schedule parameters. Start-up is further simplified with Johnson Controls 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, including 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 jobsite, 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 OpenBlue, a connected platform from Johnson Controls.
