OJ Air™ Plus Master Complete AHU Control System

The OJ Air™ Plus system has been specially designed to control a wide range of air handling units. It forms a complete control solution, where components, the BMS and Cloud services are seamlessly integrated and optimized. The OJ Air™ Plus is the system’s central controller – pre-programmed for approximately 90% of all known applications and easily configured via an intuitive browser-based interface. Built-in flexibility and a comprehensive range of system components give you a versatile control solution for your current and future ventilation portfolio. The OJ Air™ Plus system can be scaled to meet customer needs, and is designed to ensure efficient installation, fast AHU commissioning, energy-efficient operation, and minimum maintenance costs.

Easy configuration and commissioning
An intuitive browser-based interface enables full controller configuration and commissioning without any specialized programming skills. Five predefined user profiles ensure that each role has access only to the functions required for their tasks. Service personnel can perform standard operations immediately, reducing service costs and accelerating commissioning, while advanced indoor climate control and energy optimization parameters are restricted to qualified users. In addition, commissioning reports can be generated directly from the controller, fully documenting parameter settings to ensure correct operation from day one.

Smart access
An integrated WiFI Access Point gives technicians direct wireless access to settings on site – without having to access the customer’s network. This enables faster, safer and simpler commissioning and support. Using OJ Air Cloud™, service partners and manufacturer specialists can even access settings remotely for instant error notifications, quick troubleshooting, and seamless remote support. All this adds up to faster fault handling, less downtime, and significantly lower service and operating costs.
