Why is the cooling ineffective on my Johnson Controls Fan?
If cooling is ineffective on your Johnson Controls Fan, 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.
What to do if my Johnson Controls Controller displays Changeover Fail?
If your Johnson Controls Controller displays 'Changeover Fail', 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 for a Supply Temp Fail alarm to resolve this.
What causes Fan Lock on Johnson Controls TEC3000 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.
Why am I getting an error when upgrading firmware on my Johnson Controls Controller?
If the controller provides an error when trying to upgrade firmware on your Johnson Controls Controller, it means the firmware on the USB drive is below the minimum required version. Use firmware version 3.0.2.xxxx or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
What to do if the Johnson Controls TEC3000 shows 'Remote Zone Temp Fail'?
If your Johnson Controls Thermostat displays 'Remote Zone Temp Fail', it indicates that the External Zone Temperature sensor is either disconnected or has failed. Here's what you should do: 1. Check the sensor's wiring to ensure it's properly connected. 2. If the sensor was intentionally disconnected, reset the sensors through the menu. 3. If the problem continues, you may need to order replacement units and return the faulty devices to Johnson Controls under the RMA program.
Why Johnson Controls Thermostat shows Zone Temp Unreliable?
If your Johnson Controls Thermostat indicates that the Zone Temp is Unreliable, it means all sources of zone temperature, including the onboard sensor, are unreliable. To resolve this, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What should I do if my Johnson Controls Fan controller displays 'Controller Fault'?
If your Johnson Controls Fan controller displays 'Controller Fault', it means an internal fault was detected and the controller was unable to recover. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if Johnson Controls TEC3000 displays Fan Lock?
If your Johnson Controls Thermostat displays 'Fan Lock,' it means 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. Then, check sensor functionality with an ohmmeter and verify the wiring to the TEC. Next, reset the fault by entering the menu, selecting Fault Status, and selecting the Fan Lock. If problems continue, order replacement units and return the affected devices to Johnson Controls under the RMA program.
What to do if the Johnson Controls Fan is in Fan Lock?
If your Johnson Controls Fan is in Fan Lock, it means the switch connected to the BI configured for Fan Lock didn't detect airflow within 10 seconds of the fan starting, which shut down control. Here's what to do: 1. Check the equipment to make sure the fan is working. 2. Use an ohmmeter to check the sensor and verify the wiring to the TEC. 3. Reset the fault by going to the menu, selecting Fault Status, and then Fan Lock. 4. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
Why does my Johnson Controls Controller display Idle with Cooling/Heating Unavailable due to Control Mode?
If your Johnson Controls Controller displays 'Idle' with a Unit Status of 'Cooling Unavailable due to Control Mode' (despite being above the cooling setpoint) or 'Heating Unavailable due to Control Mode' (despite being below the setpoint), it indicates that the Control Mode is set incorrectly. 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.
