Updating the SD Card Screens and Manuals in the Modular Service Tool SD and System Manager SD

(Please note: Updating the SD card DOES NOT update the internal software of the Modular Service Tool SD or System Manager SD. Also, needing to update the SD card does not necessarily mean that you also need to update your Service Tool's internal software. Please consult Technical Support with any questions.)

If you were advised to update your SD card by AAON Control’s Support Department, you will need to download the file “Modular-HH-Screens.zip” onto your computer and copy and paste its contents to your SD card. In most cases you will be advised to update your SD card and your software. Please note that this process will simply update the contents of your SD card but it will not update your Modular Service Tool SD software nor will it update your System Manager SD Software.

Please “click” on the following link to open the instruction sheet on how to update your Modular Service Tool’s SD card and your System Manager’s SD card.
