What does 'Internal Sensor Fail' mean on my Johnson Controls TEC3330 Thermostat?
If your Johnson Controls Thermostat displays 'Internal Sensor Fail', it means an internal sensor on the TEC has failed. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
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 does my Johnson Controls TEC3330 say 'Econ Unavailable'?
If the Johnson Controls Thermostat displays 'Econ Unavailable', it means the outdoor air temperature sensor is not installed, has failed, or has been disconnected, and the TEC can no longer control the economizer. Follow the same steps as for an Outdoor Temp Fail alarm to resolve this.
What does the bell icon mean on my Johnson Controls TEC3330?
If the Johnson Controls Thermostat displays the Bell icon, it means a fault has been detected. Refer to Table 11 for TEC fault causes and resolution.
Why are OA Lockouts Disabled on my Johnson Controls Thermostat?
If the Johnson Controls Thermostat displays 'OA Lockouts Disabled', it means the local outdoor air temperature sensor has become disconnected or failed, or a network outdoor air temperature sensor has timed out, and the TEC is no longer shutting down equipment based on the OA lockout setpoints. If the source of outdoor air temperature was a locally connected sensor, follow the steps for the Outdoor Temp Fail alarm. If the source of outdoor air temperature was a BAS, check the BAS to ensure that it is still online and is providing the TEC with the temperature reading. If removal of the BAS mapping was intentional, reset sensors through the menu.
What causes the 'Humidity Unreliable' error on my Johnson Controls TEC3330?
If your Johnson Controls Thermostat displays 'Humidity Unreliable', it means the zone humidity reading was reliable but has now failed. If the source of zone humidity was the onboard sensor, contact Johnson Controls product sales and support. 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.
Why is dehumidification unavailable on my Johnson Controls Thermostat ('Dehum Unavailable' message)?
If your Johnson Controls Thermostat displays 'Dehum Unavailable', it means dehumidification is unavailable because the zone humidity sensor has failed or the humidity reading is not reliable. 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 the sensors through the menu. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does 'Supply Fan Runtime Limit Extended' mean on my Johnson Controls TEC3330?
If the Johnson Controls Thermostat displays 'Supply Fan Runtime Limit Extended', it means the supply fan runtime has exceeded the configured supply fan runtime limit. To resolve this, service the supply fan and reset the supply fan runtime.
What to do when my Johnson Controls TEC3330 Thermostat displays 'USB Malfunction'?
If your Johnson Controls Thermostat displays 'USB Malfunction', it means a USB drive has malfunctioned and drawn more than the maximum allowed current. To resolve this, attempt to insert and use the USB drive again, or try a new USB drive. If problems persist, order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why does my Johnson Controls Thermostat say 'Open Window'?
If your Johnson Controls Thermostat 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. Close the window to resume control. Check sensor functionality with an ohmmeter, and verify the wiring to the TEC. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
