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 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.
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 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 should I do if my Johnson Controls Controller displays Zone Temp Unreliable?
If your Johnson Controls Controller displays 'Zone Temp Unreliable,' it means all sources of zone temperature, including the onboard sensor, are unreliable. The suggested solution is to order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if Humidity is Unreliable on Johnson Controls TEC3022?
If your Johnson Controls Controller shows 'Humidity Unreliable,' it means the zone humidity reading was reliable but has now failed. Here's how to address it: 1. If the source of zone humidity was the onboard sensor, contact Johnson Controls product sales and support. 2. If the source of zone humidity was a BAS, check the BAS to ensure it's still online and providing the TEC with the humidity reading. If removing the BAS mapping was intentional, reset sensors through the menu.
Why does the zone space temperature fluctuate too much in unoccupied mode on my Johnson Controls system?
If the zone space temperature increases or decreases too much when the unit is active in unoccupied mode, it means 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.
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.
