What does 'USB Malfunction' mean on my Johnson Controls TEC3310?
If your Johnson Controls Controller displays 'USB Malfunction', it means a USB drive has malfunctioned and drawn too much current. First, try inserting the USB drive again. If that doesn't work, try a different USB drive. If the problem persists, you might need to order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does 'Zone Temp Unreliable' mean on my Johnson Controls Controller?
If your Johnson Controls Controller displays 'Zone Temp Unreliable', it means all sources of zone temperature, including the onboard sensor, are unreliable. You will need to order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why does my Johnson Controls TEC3310 Controller show 'Fan Lock'?
If your Johnson Controls Controller displays 'Fan Lock' and control has shut down, it means the switch connected to the BI configured for Fan Lock didn't sense airflow within 10 seconds of starting the fan. Here's how to address it: First, inspect the equipment to ensure the fan functions. Next, check the sensor functionality with an ohmmeter and verify the wiring to the TEC. Then, reset the fault by going to the menu, selecting Fault Status, and choosing Fan Lock. If the problem persists, you may need to order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why can't my Johnson Controls TEC3310 access a USB drive?
If the Johnson Controls Controller is unable to access a USB drive, the drive might be formatted as NTFS or another unsupported format. The TEC supports FAT and FAT32 formats only. Reformat the USB drive, or try a different USB drive with a supported format. Alternatively, the USB drive may be defective, so try a different one.
Why does my Johnson Controls TEC3310 show an error when restoring settings from a backup?
If the controller provides an error when trying to restore settings from a backup on your Johnson Controls Controller, the USB drive may be defective, the restore file may be corrupt, or the restore file may be from an incompatible model TEC. Try a different USB drive, try restoring a different backup file, and ensure that the backup file being restored was from the same model TEC.
Why is the temperature displayed lower than actual on my Johnson Controls TEC3310 Controller?
If the temperature displayed on your Johnson Controls Controller is lower than the actual room temperature, cold air drafts may be entering the back of the TEC, or air may be forced through the TEC from a nearby vent. To fix this, seal any holes behind the TEC to reduce drafts, or move the location of the TEC or change the venting to prevent air from being forced through the TEC.
How to resolve a 'Board Mismatch' error on my Johnson Controls TEC3310 Controller?
If your Johnson Controls Controller displays 'Board Mismatch', it means the baseboard and CPU board are not correctly paired. The TEC will show an error message with the model numbers of both boards. To fix this, match the baseboard to its corresponding CPU board.
What does 'Changeover Fail' mean on my Johnson Controls Controller and how to fix it?
If your Johnson Controls Controller displays 'Changeover Fail', it indicates that the Supply Temperature Sensor is either not installed, has failed, or has been disconnected. As a result, the TEC can't detect the changeover mode for cooling or heating. You can follow the same troubleshooting steps as for a 'Supply Temp Fail' alarm.
Why is the TEC3000 zone temperature not changing fast enough on my Johnson Controls TEC3310?
If the TEC3000 zone temperature on your Johnson Controls Controller isn't changing fast enough compared to a calibrated sensor, it might be because the TEC3000 is set up for larger spaces by default when a proportional device is active. To resolve this, go to Control Setup > Tuning > Equipment Size and select 'Oversized'.
How to troubleshoot a 'Supply Temp Fail' error on a Johnson Controls Controller?
If your Johnson Controls Controller displays 'Supply Temp Fail', the external supply temperature sensor is either disconnected or has failed. You can try these steps: First, check the sensor wiring. If intentionally disconnected, reset the sensors by going to the menu, then Control Setup, and selecting Inputs. If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.
