What to do if Johnson Controls Thermostat provides an error when trying to back up settings?
If the controller provides an error when trying to back up settings, it means that the USB drive is defective. Try a different USB drive.
What to do if Johnson Controls Thermostat provides an error when trying to upgrade firmware?
If your controller shows an error (Error code 1025) when upgrading firmware, it means the firmware on the USB drive is below the minimum required version. Please use firmware version 3.0.2.xxxx (for networked models) or 2.0.2.xxxx (for wireless models) or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
Why is Johnson Controls Thermostat requesting cooling in Heating Mode?
Change the Control Mode to Auto or Cooling.
Why doesn't the TEC3000 zone temperature change fast enough on my Johnson Controls Fan?
The TEC3000 is configured by default for larger spaces with normal-sized equipment when a proportional device is active. 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.
What to do if Johnson Controls Controller provides an error when trying to back up settings?
If your Johnson Controls Controller provides an error when trying to back up settings, it means the USB drive is defective. Try a different USB drive.
Why does my Johnson Controls TEC3022 say 'Cooling Unavailable due to Control Mode' or 'Heating Unavailable due to Control Mode'?
If your Johnson Controls Controller displays 'Idle' with a unit status of 'Cooling Unavailable due to Control Mode' (even when above the cooling setpoint) or 'Heating Unavailable due to Control Mode' (even when below the heating setpoint), it indicates that the control mode setting is incorrect. Here’s what you should do: * 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'.
Why does my Johnson Controls heat pump heat when it should cool, and cool when it should heat?
If your heat pump heats when it should be cooling, and cools when it should be heating, it indicates that the reversing valve polarity is set incorrectly. To fix this, consult the equipment documentation to verify the correct reversing valve polarity, and then adjust the Reversing Valve Polarity menu option accordingly.
What to do if Johnson Controls Thermostat shows Dirty Filter?
If your thermostat displays a 'Dirty Filter' alarm, it means that equipment connected to the BI configured for a Dirty Filter alarm is triggering the alarm. Replace the filter in the equipment as explained in the manufacturer's instructions.
What does Cooling Ineffective mean on Johnson Controls Thermostat?
If your Johnson Controls Thermostat displays 'Cooling Ineffective', 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.
