If your Johnson Controls Thermostat displays 'Heating Ineffective', it means the Supply Air Temperature hasn't increased above the configured Supply Air Temperature Alarm Offset while heating has been active for at least the Supply Air Temperature Alarm Delay. Verify that the heating elements on the rooftop are functioning properly.
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.
What to do if Johnson Controls TEC3022 provides an error when trying to upgrade firmware?
If your Johnson Controls Controller provides an error when trying to upgrade the firmware, it means the firmware on the USB drive is below the minimum required version (Error code 1025). Please use firmware version 2.0.2.xxxx or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
Why is my Zone Temperature Too Cold according to my Johnson Controls TEC3022?
If your Johnson Controls Controller indicates that the zone temperature is too cold, it means the zone temperature has dropped below the configured Zone Temp Low Limit. To address this, verify that the TEC and the RTU heating are both enabled and functioning correctly.
What does the Bell icon on my Johnson Controls TEC home page mean?
If the Bell icon is displayed on the TEC home page, it means a fault has been detected on the TEC. See Table 12 for TEC fault causes and resolution.
Why does the Johnson Controls Fan controller show an error when trying to upgrade the firmware?
If the Johnson Controls Fan controller shows an error when trying to upgrade the firmware, it means the firmware on the USB drive is below the minimum required version (Error code 1025). 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 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 my Johnson Controls Thermostat requesting heating in Cooling Mode?
Change the Control Mode to Auto or Heating.
Why is Johnson Controls Thermostat requesting cooling in Heating Mode?
