What causes a 'Board Mismatch' error on a Johnson Controls Fan?
A 'Board Mismatch' error on your Johnson Controls Fan means the baseboard and CPU board are paired incorrectly, and an error message will appear on the TEC indicating the model number of each board. Match the baseboard to its corresponding CPU board. Consult Figure 6 and Table 3 for pairing information.
What to do if the Johnson Controls Fan is in Fan Lock?
If your Johnson Controls Fan is in Fan Lock, it means the switch connected to the BI configured for Fan Lock didn't detect airflow within 10 seconds of the fan starting, which shut down control. Here's what to do: 1. Check the equipment to make sure the fan is working. 2. Use an ohmmeter to check the sensor and verify the wiring to the TEC. 3. Reset the fault by going to the menu, selecting Fault Status, and then Fan Lock. 4. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
How to fix an unresponsive touchscreen on a Johnson Controls Fan?
If the touchscreen on your Johnson Controls Fan is unresponsive, it indicates that the touchscreen components have failed to initialize. First, try rebooting the controller. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What causes the 'Supply Fan Runtime Limit Extended' error on my Johnson Controls Fan, and how do I fix it?
The 'Supply Fan Runtime Limit Extended' error on your Johnson Controls Fan means that the supply fan runtime has exceeded the configured limit. To resolve this, first service the supply fan, then reset the supply fan runtime.
What to do if my Johnson Controls Fan reports a USB malfunction?
If your Johnson Controls Fan reports a USB malfunction, it means a USB drive has malfunctioned and drawn more current than allowed. Try inserting the USB drive again. If that doesn't work, try a new USB drive. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if my Johnson Controls Controller displays Board Mismatch?
If the Johnson Controls Controller displays Board Mismatch, it means that 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. Alternatively, a hardware failure might be causing the two boards to incorrectly identify themselves, in which case you should order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why does my Johnson Controls Controller show 'Supervisory Status = Offline'?
For wireless models, if the Supervisory Status is Offline, map the TEC into a JCI Supervisory system. Verify that the PAN’s WNC or WRG Gateway is online. Add ZFR182x or ZFR183x Routers/Repeaters into the wireless system. The supervisory controller is not communicating with the TEC, the TEC is not mapped to a JCI Supervisory System, or the WNC or WRG Gateway is not communicating with the TEC.
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.
What does it mean when the humidity reading is unreliable on a Johnson Controls Fan?
If the humidity reading on your Johnson Controls Fan is unreliable, it means the zone humidity reading was once reliable but has now failed. If the source of zone humidity was the onboard sensor, contact Johnson Controls product sales and support. If the source was a BAS, check the BAS to ensure it's online and providing the TEC with the humidity reading. If the BAS mapping was intentionally removed, reset the sensors through the menu.
Why is the cooling ineffective on my Johnson Controls Fan?
If cooling is ineffective on your Johnson Controls Fan, it means the supply air temperature hasn't decreased below the configured Supply Air Temperature Alarm Offset while cooling has been active for at least the Supply Air Temperature Alarm Delay. Verify that the cooling elements on the rooftop are functioning properly.
