What to do if my Johnson Controls TEC-3620 Controller shows 'Dirty Filter'?
If your Johnson Controls Controller displays a 'Dirty Filter' message, it means the equipment connected to the BI configured for a Dirty Filter alarm is triggering the alarm. Replace the filter in the equipment according to the manufacturer's instructions.
What does 'Service' mean on my Johnson Controls TEC-3620 Controller?
If your Johnson Controls Controller displays 'Service', it indicates that equipment connected to the BI configured for a Service alarm is triggering the alarm. Service the equipment per the manufacturer's recommendation.
What to do if Johnson Controls TEC-3620 Controller displays 'Open Window'?
If your Johnson Controls Controller displays 'Open Window', it means the switch connected to the BI configured for Open Window is sensing that the window is opened, and control has shut down. First, close the window to resume control. Next, check sensor functionality with an ohmmeter and verify the wiring to the TEC.
How to fix 'Fan Lock' on Johnson Controls Controller?
If your Johnson Controls Controller displays 'Fan Lock', it means that the switch connected to the BI configured for Fan Lock did not sense airflow within 10 seconds of starting the fan, and control has been shut down. First, inspect the equipment to ensure the fan functions. Next, check sensor functionality with an ohmmeter and verify wiring to the TEC. Then, reset the fault by entering the menu, selecting Fault Status, and selecting the Fan Lock.
Why does my Johnson Controls TEC-3620 show 'Remote Zone Temp Fail'?
The 'Remote Zone Temp Fail' message on your Johnson Controls Controller indicates that the External Zone Temperature sensor has been disconnected or has failed. Check the wiring of the sensor. If intentionally disconnected, reset sensors through the menu.
What does 'Supply Temp Fail' mean on my Johnson Controls TEC-3620?
The 'Supply Temp Fail' message on your Johnson Controls Controller indicates that the External Supply Temperature sensor has been disconnected or has failed. Check the wiring of the sensor. If intentionally disconnected, reset sensors through the menu.
What to do if Johnson Controls TEC-3620 Controller displays 'Changeover Fail'?
The 'Changeover Fail' message on your Johnson Controls Controller means that the Supply Temperature Sensor is not installed, has failed, or has been disconnected and the TEC can no longer detect changeover mode to cool or heat. Follow the same steps as the Supply Temp Fail alarm: check the wiring of the sensor and, if intentionally disconnected, reset sensors through the menu.
What to do if my Johnson Controls Controller says 'Dehum Unavailable'?
If your Johnson Controls Controller displays 'Dehum Unavailable', it means dehumidification is unavailable because the zone humidity sensor has failed. Replace the thermostat controller.
What does 'Humidity Unreliable' mean on my Johnson Controls TEC-3620?
If your Johnson Controls Controller displays 'Humidity Unreliable', it means the zone humidity reading was reliable and has now failed. If the source of zone humidity was a BAS, check the BAS to ensure that it is still online and providing the TEC with the humidity reading. If removal of the BAS mapping was intentional, reset sensors through the menu.
