What to do if my Johnson Controls Controller displays Changeover Fail?
If your Johnson Controls Controller displays 'Changeover Fail', the Supply Temperature Sensor is not installed, has failed, or has been disconnected, and the TEC can no longer detect changeover mode to cool or heat. Follow the same steps as for a Supply Temp Fail alarm to resolve this.
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 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 to do when the Johnson Controls Fan displays a 'Supply Fan Fault'?
If your Johnson Controls Fan displays a 'Supply Fan Fault,' it means the Supply Fan Status configured for either BI1 or BI2 hasn't been proven within the configured Fan Alarm Delay. First, verify that the supply fan is operating when turned on. Also, verify that the Supply Fan Status wiring is connected correctly.
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.
Why TEC3000 zone temperature doesn't change fast enough?
If the TEC3000 zone temperature does not change fast enough compared to the measured zone temperature from a verification device, it is because the TEC3000 is configured by default for larger spaces with normal-sized equipment when a proportional device is active. To resolve this, select Control Setup > Tuning > Equipment Size > Oversized.
Why does my Johnson Controls Thermostat display Partial Restore Complete?
If your thermostat displays 'Partial Restore Complete' when restoring from a backup, it means not all items in the backup file were restored. This can happen if a value is outside the acceptable range or if there are inconsistencies in a setting's reliability. To resolve: 1. Create a Backup file on a USB drive for the TEC that is showing the issue. 2. Edit the backup file created in the previous step on a PC to reflect the desired settings. 3. Verify that the modified values are within minimum and maximum range in the backup file. 4. Restore the settings from the newly edited backup file on the TEC.
Why is Johnson Controls Thermostat requesting cooling in Heating Mode?
Change the Control Mode to Auto or Cooling.
Why does my Johnson Controls Controller display Idle with Cooling/Heating Unavailable due to Control Mode?
If your Johnson Controls Controller displays 'Idle' with a Unit Status of 'Cooling Unavailable due to Control Mode' (despite being above the cooling setpoint) or 'Heating Unavailable due to Control Mode' (despite being below the setpoint), it indicates that the Control Mode is set incorrectly. If the Control Mode is set to Cooling Mode, but the controller is requesting heating, change the Control Mode to Auto or Heating. If the Control Mode is set to Heating Mode, but the controller is requesting cooling, change the Control Mode to Auto or Cooling.
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.
