What does 'Calibration Corrupt' mean on my Johnson Controls TEC3330?
If your Johnson Controls Thermostat displays 'Calibration Corrupt', it means the factory calibration data is lost or not installed. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does 'Dirty Filter' mean on my Johnson Controls Thermostat and how to resolve it?
If your Johnson Controls Thermostat displays '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.
What to do if my Johnson Controls Thermostat displays 'Zone Temp Unreliable'?
If your Johnson Controls Thermostat displays 'Zone Temp Unreliable', it means all sources of zone temperature, including the onboard sensor, are unreliable. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why is my Johnson Controls Thermostat cycling too rapidly or slowly?
If your Johnson Controls Thermostat displays 'The staged equipment cycles too rapidly or too slowly when the PID is running on the TEC', it means the control band around the setpoint is determined by the minimum on/off times and is set incorrectly for the equipment, zone, or user preference. Verify that equipment minimum on/ off times are set correctly. If the default deadband around the setpoint does not provide the desired temperature control, set Temp Control Setup to Deadband Override and set the Deadband parameter to the desired value.
Why can't my Johnson Controls TEC3330 access the USB drive?
If the Johnson Controls Thermostat displays 'The controller is unable to access a USB drive', it could be due to the drive being formatted as NTFS or another unsupported format. The TEC supports FAT and FAT32 formats only, so reformat the USB drive, or try a different USB drive with a supported format. It may also be that the USB drive is defective, so try a different USB drive.
Why does my Johnson Controls Thermostat show an error when upgrading firmware?
If the Johnson Controls Thermostat displays 'The controller provides an error when trying to upgrade firmware', it means the firmware on the USB drive is below the minimum required version. Please use firmware version 3.0.2.xxxx or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
Why does my Johnson Controls TEC3330 display 'Board Mismatch'?
If the Johnson Controls Thermostat displays 'The controller displays Board Mismatch', it could be due to the I/O board that the display board is currently attached to does not match the one that initially shipped with the display board, so attach the display board to the correct I/O board. It could also be that a hardware failure is causing the two boards to incorrectly identify themselves, so order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if my Johnson Controls Thermostat displays 'Supply Temp Fail'?
If the Johnson Controls Thermostat displays 'Supply Temp Fail', it means the external supply temperature sensor has either been disconnected or has failed. Here's what you should do: 1. Check the wiring of the sensor. 2. If intentionally disconnected, reset fault by entering the menu, enter Control Setup, and select Inputs to reset the sensors. 3. If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if my Johnson Controls Thermostat displays 'Outdoor Temp Fail'?
If the Johnson Controls Thermostat displays 'Outdoor Temp Fail', it means the external outdoor air temperature sensor is either disconnected or has failed. Here's what you should do: * Check the sensor wiring. * If intentionally disconnected, reset sensors through the menu. * If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does 'Board Mismatch' mean on my Johnson Controls Thermostat and how to fix it?
If your Johnson Controls Thermostat displays 'Board Mismatch', it means the baseboard and CPU board are incorrectly paired. To resolve this, match the baseboard to its corresponding CPU board. See Figure 5 for information on ensuring that you have the CPU board and base board paired correctly.
