OJ ElectronicsControllers

To deliver competitive ventilation systems, OEMs need controllers that ensure optimal performance and energy efficiency, combined with fast, efficient setup and commissioning.

OJ ventilation controllers combine extensive pre-programmed AHU functionality with freely configurable flexibility, covering around 90% of standard air handling units while reducing engineering work and commissioning time.

For you and your customers, this means faster development, streamlined installation and servicing, and consistent performance across your product range.

A Different Approach to Ventilation Control

Built on OJ’s state-of-the-art control platform, our controllers combine extensive pre-programmed AHU functionality with a highly configurable architecture.

Pre-programmed applications and control logic reduce engineering effort and commissioning time, while flexible configuration options allow each solution to be adapted to specific AHU designs and customer requirements without extensive programming. Our intuitive engineering and configuration platform, along with our cloud solution, simplify setup, commissioning, operation, and servicing, giving all users fast access to the information and functionality they need.

Simplified integration and flexible adaptation across a wide range of AHU designs enable you to bring differentiated ventilation systems to market faster, while also simplifying commissioning and servicing on site.

Key Controller Technologies

OJ controllers combine advanced control capabilities with the flexibility required by modern AHUs. Key features include:

Models optimized for both compact and modular AHUs
Compact, OEM-friendly design and integration options
Role-based interfaces tailored to engineers, service technicians, and end users
Control algorithms for energy optimization
Multiple communication options and seamless BMS integration
Cloud connectivity with secure remote access
Real-time monitoring, diagnostics, alarms, and service functionality
Energy optimization and demand-based ventilation control
Integrated support for sensors, drives, dampers, heating, cooling, and air quality management

Service and Support Without Delays

For service teams, quick and easy access to the controller is essential. With a built-in Wi-Fi access point, technicians can connect directly to the system without accessing the customer’s network. OJ Air Cloud™ enables monitoring, real-time diagnostics, and support without requiring on-site presence. Separate access paths for local and remote interaction further support secure and flexible servicing.

All this simplifies troubleshooting, reduces downtime, and lowers overall service costs.
