Why is Heating Ineffective on my Johnson Controls Thermostat?
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.
Why is Heating Ineffective on my Johnson Controls Controller?
If your Johnson Controls Controller indicates 'Heating Ineffective,' it means the supply air temperature hasn't increased above the configured Supply Air Temperature Alarm Offset, even though heating has been active for at least the Supply Air Temperature Alarm Delay. To resolve this, verify that the heating elements on the rooftop are functioning properly.
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'.
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 my Johnson Controls Fan indicates 'Dirty Filter'?
If your Johnson Controls Fan indicates 'Dirty Filter', it means 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.
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?
Change the Control Mode to Auto or Cooling.
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.
