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.
How do I resolve a Firmware Mismatch error on my Johnson Controls Thermostat?
A 'Firmware Mismatch' error on your Johnson Controls Thermostat can occur for a couple of reasons: * If the previous upgrade hasn't completed: 1. Upgrade the TEC3000 to the latest released version. 2. Upgrade the TEC3000 to the current version again. * If a previous downgrade hasn't completed because the previous version is no longer supported: Reboot the TEC3000 to clear the fault.
What causes Fan Lock on Johnson Controls Thermostat and how to resolve it?
If your Johnson Controls Thermostat displays 'Fan Lock', the switch connected to the BI configured for Fan Lock didn't sense airflow within 10 seconds of starting the fan, and control has been shut down. To resolve this: 1. Inspect equipment to ensure fan functions. 2. Check sensor functionality with an ohmmeter, and verify wiring to the TEC. 3. Reset fault by entering the menu, selecting Fault Status, and selecting the Fan Lock. 4. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What does the Bell icon on my Johnson Controls TEC Thermostat mean?
If the Bell icon is displayed on the TEC home page, it means a fault has been detected on the TEC. See Table 15 for TEC fault causes and resolution.
What to do if the Johnson Controls Fan shows 'Remote Zone Temp Fail'?
If the Johnson Controls Fan displays a 'Remote Zone Temp Fail' message, it means the external zone temperature sensor is either disconnected or has failed. First, check the sensor's wiring. If the sensor was intentionally disconnected, reset the sensors through the menu. If the problem continues, you should order replacement units and return the faulty devices to Johnson Controls under the RMA program.
What causes the Johnson Controls Fan to display 'Zone Temperature Too Hot' and how do I fix it?
If your Johnson Controls Fan displays 'Zone Temperature Too Hot', it means the zone temperature has exceeded the configured Zone Temp High Limit. To fix this, verify that the TEC and the RTU cooling are enabled and functioning correctly.
What does it mean when my Johnson Controls TEC3022 Controller displays an Open Window error?
If your Johnson Controls Controller displays an 'Open Window' error, it means the switch connected to the BI configured for Open Window is sensing that a window is open, and control has been shut down. Here's how to resolve it: 1. Close the window to resume control. 2. Check the sensor functionality with an ohmmeter, and verify the wiring to the TEC. 3. If problems persist, order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why doesn't the TEC3000 zone temperature change fast enough on my Johnson Controls Fan?
The TEC3000 is configured by default for larger spaces with normal-sized equipment when a proportional device is active. Select Control Setup >Tuning > Equipment Size > Oversized.
Why does the zone space temperature fluctuate too much in unoccupied mode on my Johnson Controls system?
If the zone space temperature increases or decreases too much when the unit is active in unoccupied mode, it means the heating and cooling equipment are too big for the unoccupied space. Decrease the 'Unoccupied Off Delay' parameter from 10 minutes to a more appropriate time for the equipment configuration.
Why does my Johnson Controls Thermostat TEC3x3x show Outdoor Temp Fail?
The 'Outdoor Temp Fail' message on your TEC3x3x Thermostat means the external outdoor air temperature sensor is either disconnected or has failed. Try these steps: 1. Check the sensor wiring. 2. If you intentionally disconnected the sensor, reset the sensors through the menu. 3. If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.
