OJ Air CloudOJ Air Cloud® for AHU and ventilation control

Improve AHU and ventilation control with OJ Air Cloud® 

OJ Electronics’ offers a cloud-based system developed especially for customers, using OJ AHU controllers. The system is called OJ Air Cloud® and it aims to assist facility managers, working to ensure more hours of flawless ventilation performance. The target is to provide a healthier working environment for people inside the building, and to give facility owners happier tenants, enjoying higher productivity and fewer sick days among their staff.

Be notified instantly when performance deviates

In the event indoor climate in your building deviates from your set standard, or in case energy consumption increases due to poor ventilation system performance, you immediately receive an e-mail with information about the deviation, allowing you to take action right away.

Troubleshoot directly via cloud

The OJ Air Cloud® helps you reduce AHU system downtime by enabling quicker, easier, and smoother troubleshooting than ever.

Enjoy full remote support

Accessing the OJ-Air2 webserver remotely through the secure OJ Air Cloud® allows your busy service partner or faraway manufacturer specialists to act as technical back up for the on-site service crew.

Reduce cost of service

Fine-tuning system operation through remote access saves time – not only for you. Your service partner is spared several hours of driving in his van, as the advanced remote access to details about imminent ventilation system issues, allows him to assess if a visit is needed. And if so, to prepare accordingly, get the right spare parts ready, and pack necessary components in the service van.

Minimise Carbon footprint

A well-maintained ventilation system always keeps the energy consumption on track, avoiding excessive utility costs, and keeping the CO2 emissions at a minimum.

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.
