For you as an AHU OEM, that means a stronger total offering for your customers – with valuable digital capabilities already built around the control solution.
OJ Air CloudAdd Digital Value to Your AHUs
The value of an AHU increasingly extends beyond the equipment itself.
Customers and service partners expect easy access to operating information, efficient troubleshooting and the ability to support installations without always having to be on site.
OJ Air Cloud gives you a ready-made digital layer for compatible OJ Air controllers, helping you add connectivity and remote services to your AHU offering without having to develop and maintain the cloud infrastructure yourself.
With OJ Air Cloud, you can offer your customers:
- Secure remote access to connected AHUs
- Alarm monitoring and alarm information
- Remote adjustment of selected settings
- Reporting and data export
- Access across PC, tablet and smartphone
The result is an AHU solution that is easier to support, easier to service and more valuable throughout its lifetime.
OJ Air CloudTurn Operating Data
into Actionable Insight
OJ Air Cloud brings operating information from connected AHUs together in one place, helping users understand what is happening now – and how operation has developed over time.
Monitor
Get a clear overview of connected installations, current operating values, system status and alarms.
Users can monitor temperatures, airflow, pressure, fan operation, operating modes and other available controller values depending on the AHU configuration.
Analyze
Historical operating data and graphical trends make it easier to compare current and previous performance.
Users can investigate changes over time, identify unusual operating patterns and use the available data to support performance analysis and continuous optimization.
Troubleshoot
Detailed alarms, alarm codes and descriptions help users understand what is happening within the AHU.
Combined with access to live and historical operating information, this gives service teams a stronger basis for investigating problems remotely and deciding what action is needed.
Optimize
Remote access to operating information and selected settings makes it easier to fine-tune installations, document operation and support efficient operation throughout the AHU lifecycle.
OJ Air CloudBetter Information. Better Service.
Not every issue requires an immediate visit to site. With OJ Air Cloud, service partners can inspect operating values, alarms and historical information remotely before deciding how to respond.
In some cases, an issue can be investigated or resolved remotely. When a site visit is necessary, the technician can arrive with a better understanding of the situation and be better prepared with the relevant tools, knowledge or replacement components.

OJ Air CloudBenefits
- Reduce unnecessary service visits
- Improve troubleshooting efficiency
- Shorten response times
- Support better preparation before site visits
- Reduce downtime
- Improve communication between OEMs, service partners and facility managers with easy documentation

OJ Air CloudWorks Alongside Existing BMS
OJ Air Cloud is not intended to replace the building management system. The AHU continues to be controlled locally through the OJ Air controller and can remain integrated with the building automation system through technologies such as BACnet or Modbus.
OJ Air Cloud adds another layer: remote access, controller-level insight and cloud-based services around the AHU. This gives service partners, OEMs and other authorized users direct access to information from the OJ control system without relying solely on the building’s BMS.
Depending on the controller and installation, OJ Air Cloud can also support functions such as remote configuration, software updates, historical data storage and access to controller information that can assist with BMS integration and troubleshooting.

OJ Air CloudA Cloud Platform You Do Not Have to Build Yourself
Adding digital services to HVAC equipment requires more than connecting a controller to the internet.
It also requires secure communication, data storage, user management, application development, hosting, maintenance and ongoing security work.
With OJ Air Cloud, this infrastructure is already built around the OJ Air control platform.
OJ Electronics handles the cloud environment so you can focus on developing and delivering your AHU solutions. Since 2018, we have continuously developed and enhanced our cloud platform, adding new functionality and improving the user experience over time.
Secure by design
Communication between compatible controllers, OJ Air Cloud and users takes place through encrypted connections.
Secure authentication and controlled access help ensure that only authorized users can access connected systems and data.
GDPR compliant
Personal data is handled in accordance with GDPR and applicable data protection requirements.
Built for professional HVAC applications
OJ Air Cloud is developed specifically for use with OJ Electronics HVAC controllers and the requirements surrounding connected air handling units.
Continuously maintained
OJ Electronics continuously maintains and develops OJ Air Cloud with focus on reliability, usability, security and compatibility.
OJ Air CloudWhite-label OJ Air Cloud
For OEM partners, OJ Air Cloud can be made available as a white-label solution with your own branding. Adding your company name, logo and visual identity allows the cloud platform to become part of your own digital offering and customer experience.
It gives you an opportunity to extend your relationship with the customer beyond delivery of the AHU and provide an additional digital service throughout the equipment lifecycle.
