OJ Air Cloud® for AHU and ventilation control

OJ Air Cloud® is a system developed especially for OJ Electronic’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 (even better!) 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.

    Due to security reasons it is necessary to apply the right cloud enable keys to the OJ Air2 controllers to get Cloud access.
    It’s done in a few steps.

    1. Readout the “MAC address” from the device’s that you want to update. The MAC address can be read from the web or from the HMI.
    2. Send the MAC address or a number of MAC addresses in an Email to the responsible contact person in our CUSTOMER SERVICE DEPARTMENT (Excisting customers only).
    3. OJ will within 3 working days reply to the mail with a key file.
    4. If the controller is updated to SW 5.04 then apply the key file “AHU_Cloud.key” to an SD card and insert it to the controller. Do not rename the file!
    5. If the controller isn’t updated to SW 5.04 then apply both the SW files and the key file to the SD card and make the SW update. The update takes approximately 8 minutes DON’T TURN OFF THE POWER during the update! The HMI may indicate different failure messages during the update, wait until the home menu turns on.
    6. After the update has been finished you will find the Cloud menu under the Communication menu. Here you activate the cloud and find the activation code.
    7. On the OJ homepage you will find more information about the OJ Air Cloud benefits.

     

    Additional information:

    1. Up till 8Gb HC SD cards can be used from version 2.19. The SD-card shall have a MBR with msdos partition table, and the first primary partition in it shall be VFAT (or FAT32) file system.
    2. The SW upgrade from SW 2.XX to SW 5.XX isn’t possible! Hence you must update to SW 3.XX and then update to SW 5.04 or higher. This is only possible if the label on the front says “SOFTWARE 3.xx READY”
    3. Upgrading to 5.04 will require 3 files:
      “air2_v207_update_rd.gz”
      “version.crc” (1kB, 28-06-2019, 11:13)
      “air2_v504_update_jffs2.tar.gz”
    4. Note that the old HMI (OJ-AIR2Hterm) don’t have the Cloud menu.
      Hence you must activate the Cloud from the web interface.
    5. The keys only work with the MAC addresses that you have asked for. Be careful that you read them correctly.
