OJ Air Cloud® for AHU and ventilation control

OJ Air Cloud® is a system developed especially for OJ Electronics™s HVAC controllers. The users, which can include facility managers, service partners and AHU manufacturers, can all invite each other to be part of OJ Air Cloud®, and as you would expect, the cloud-based system provides a total overview of all the systems connected to the cloud and their current status. This enables rapid identification and
diagnostics of any problems – allowing you and your partners to arrive at the right solution quickly.


Troubleshooting from the cloud

OJ Air Cloud® helps reduce downtime of AHU systems by enabling quicker, easier troubleshooting than ever.


Effective planning

On PCs, OJ Air Cloud® gives access to the feature known as Map view. Map view gives users a visual overview of the actual physical locations of the AHU systems connected to the cloud, enabling them to plan their travel time with maximum efficiency when scheduling service visits.


What you see, they see

With OJ Air Cloud®, everyone is on the same page. This means that facility managers and service partners minimise the risk of misunderstandings in their co-operation.


Be prepared

Having advance access to details about problem sites via OJ Air Cloud® means that service partners can check everything they need to know beforehand and arrive at the site fully prepared with the right components and spare parts ready in the van.


Simple data access

The OJ Air Cloud® solution offers API: users can access the data directly in the database, which means that they can develop their own interfaces.

Check your system in real time

OJ Air Cloud® lets you access plenty of information in easy-to-view, real-time formats via PC (Windows, MAC), tablet (Android, iOS) and smartphones (Android, iOS). Heres a rundown of the features currently available.


Dashboard view

The dashboard view function can be used on all devices. Here users can monitor AHU systems and their operation via a chart overview that shows any current A and B alarms, devices and logs of user actions.


Map view

On PCs, OJ Air Cloud® gives access to Map view. a visual overview of the actual physical locations of the AHU systems connected to the cloud. This allows you to plan service visits and travel times with maximum efficiency.



Get an overview of all the AHUs connected to your OJ Air Cloud® account either from the dashboard view or map view. If you handle several AHU systems, you can get an instant overview of all your systems, regardless of location – and quickly identify any alarm sites. You can also add new AHU systems as required.


Device view

Select a specific system from Device to access Device view, which gives you access to the following information:

Alarm overview

Get a quick overview of the alarms associated with the selected AHU system. OJ Air Cloud logs alarms, recording when they arose and on which system.


Config device

Here you can name your AHUs and position them in map view (enter co-ordinates).


Device operation

Here you can change various parameters in the AHU, such as temperature setpoint and time zone.



Here you can plan the AHUs operation for the next two years and schedule any holidays or downtime periods where the system should run at reduced capacity or be switched off altogether.


Device users

Shows all the users who can access the chosen AHU system.


Table view

A list of all parameters of the AHU system such as operation mode, temperature regulation and fan regulation and their current stats. The exact list will reflect the options connected to the system.


Graph overview

A graphic visualisation of the systemas current temperatures and pressure (supply and extract air).


Monitoring graphic view

Here you will find visual depictions of the readings taken by the various sensors connected to your AHU system. This enables rapid visual identification of any errors: you can instantly see any unusual and unintentional deviations from the usual curves.


User change log

Users can log any changes they make to the system, ensuring that can be seen and remembered by everyone in future.



API (application programming interfacing) means that you can access all data directly in the database and develop your own interfaces, showing the information exactly as you wish.
