Why does the Johnson Controls Fan controller show an error when trying to back up settings?
If the Johnson Controls Fan controller shows an error when trying to back up settings, the USB drive may be defective. Try a different USB drive.
Why does the Johnson Controls Fan controller show an error when trying to restore settings from a backup?
If the Johnson Controls Fan controller displays an error when restoring settings from a backup, it could be due to several reasons. The USB drive may be defective, so try a different USB drive. The restore file might be corrupt, so try restoring a different backup file. Also, ensure that the backup file being restored was from the same model TEC.
Why is my Johnson Controls Fan controller unable to access a USB drive?
If your Johnson Controls Fan controller can't access a USB drive, it might be because the drive is formatted as NTFS or another unsupported format. The TEC supports FAT (for networked models), FAT16 (for wireless models), and FAT32 (for all models) formats only. Try reformatting the USB drive or use a different USB drive with a supported format. The USB drive may also be defective, so trying a different one is a good step.
What should I do if my Johnson Controls Fan controller displays 'Board Mismatch'?
If your Johnson Controls Fan controller displays 'Board Mismatch', it means the I/O board that the display board is currently attached to does not match the one that initially shipped with the display board. Attach the display board to the correct I/O board. If the problem persists, a hardware failure may be causing the two boards to incorrectly identify themselves; in this case, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What should I do if my Johnson Controls Fan controller displays 'Controller Fault'?
If your Johnson Controls Fan controller displays 'Controller Fault', it means an internal fault was detected and the controller was unable to recover. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does 'Partial Restore Complete' mean when restoring settings on my Johnson Controls Fan?
If 'Partial Restore Complete' is displayed when restoring settings on your Johnson Controls Fan, it means not all items in the backup file have been restored. This can happen if a value in the backup file is outside the acceptable minimum or maximum range. To fix this, create a backup file on a USB drive for the TEC that's showing the issue. Edit this backup file on a PC to reflect the desired settings, ensuring the modified values are within the valid range. Finally, restore the settings from this newly edited backup file on the TEC.
Why is the temperature displayed on my Johnson Controls Fan lower than the actual room temperature?
If the temperature displayed on your Johnson Controls Fan is lower than the actual room temperature, it could be due to cold air drafts entering the back of the TEC. Seal any holes behind the TEC to reduce drafts. Alternatively, air might be forced through the TEC from a nearby vent, in which case you should move the location of the TEC or change the venting to prevent air from being forced through it.
Why does the zone space temperature change too much in unoccupied mode on my Johnson Controls Fan?
The heating and cooling equipment are too big for the unoccupied space. Decrease the Unoccupied Off Delay parameter from 10 minutes to a more appropriate time for the equipment configuration.
Why doesn't the Online icon appear for my networked Johnson Controls Fan controller?
If the Online icon doesn't appear for your networked Johnson Controls Fan controller, there might be improper field bus wiring. Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for guidance.
Why does my wireless Johnson Controls Fan show 'Supervisory Status = Offline'?
If your wireless Johnson Controls Fan shows 'Supervisory Status = Offline', it means the supervisory controller isn't communicating with the TEC. This could be because the TEC isn't mapped to a JCI Supervisory System, or the WNC Gateway isn't communicating with the TEC. To resolve this, map the TEC into a JCI Supervisory system, verify that the PAN’s WNC Gateway is online, and add ZFR Pro Routers/Repeaters into the wireless system.
