Modular and compact systems<\/small>OJ Air\u2122 Plus master controller<\/h1>\n
\n
<\/div>\n

A controller that simplifies every stage of your ventilation system<\/h4>\n

In modern air handling units, the controller plays a key role in how systems are integrated, installed and commissioned, operated, and maintained.<\/p>\n

With its reimagined user-based interface and many other advances, the OJ Air\u2122 Plus is designed to make that role simpler, faster, and more reliable for everyone working with the system.<\/p>\n

For your OEM business, the time and cost savings this new controller delivers throughout your AHU\u2019s lifecycle add up to a stronger business case and more satisfied customers.<\/p>\n

OJ Air\u2122 Plus<\/small>Fits Seamlessly Into
Your AHU Design<\/h2>\n
\n

Controller integration into AHU designs is a critical first step for any OEM. If the controller is designed flexibly and offers broad compatibility, integration is quick and easy \u2013 saving time and money at integration and beyond.<\/p>\n

The OJ Air\u2122 Plus is a highly flexible control platform<\/strong> that integrates easily into a wide range of AHU configurations. With its broad mix of I\/O, multiple communication ports, and built-in Modbus support, it connects directly to key components<\/strong> such as drives<\/strong>, sensors<\/strong>, and actuators<\/strong>, as well as to BMS systems<\/strong>.<\/p>\n

Built-in Modbus communication for plug fans and actuators, combined with support for OJ Electronics components and third-party devices, enable a seamless digital bus inside the AHU. This reduces wiring complexity, simplifies system design, and makes it easier to standardize solutions across your product portfolio.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n

OJ Air\u2122 Plus<\/small>Faster Installation and Commissioning<\/h2>\n
\n

Pre-programmed for compatibility with approximately 90% of standard AHU applications, the OJ Air\u2122 Plus comes ready to configure out of the box<\/strong>.<\/p>\n

Via a browser-based interface<\/strong>, systems can be configured and commissioned without specialized programming. A visual drag-and-drop approach simplifies setup<\/strong> and makes it easier to match the controller to the specific AHU design \u2013 reducing setup time and shortening the path to stable operation.<\/p>\n

The result is faster installation<\/strong>, more predictable commissioning<\/strong>, and fewer errors<\/strong> during system start-up.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

OJ Air\u2122 Plus<\/small>Efficient User-Tailored Operation<\/h2>\n
\n

Once your AHU is running, the OJ Air\u2122 Plus supports efficient day-to-day operation through a uniquely user-centric interface<\/strong>.<\/p>\n

Five dedicated user profiles<\/strong> ensure that each role \u2013 from facility manager to service technician<\/strong> \u2013 has access to the functions and information they need. Advanced settings, for example, are available only to qualified users, helping protect system stability while still enabling deeper optimization where needed.<\/p>\n

All this reduces complexity, limits the risk of incorrect adjustments, and makes it easier to maintain stable system performance<\/strong> over time.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n
