This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This Class (B) digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la Classe (B) respecte toutes les exigences du Règlement sur le matériel brouilleur
du Canada.

    What causes Fan Lock on Johnson Controls TEC3000 Thermostat and how to resolve it?
    • A
      Amy SmithAug 26, 2025
      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 is Cooling Ineffective on Johnson Controls TEC3000?
    • A
      Amanda HorneAug 31, 2025
      If cooling is ineffective on your Johnson Controls Thermostat, it means the Supply Air Temperature has not 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 correctly.

    Why does my Johnson Controls Controller display Idle with Cooling/Heating Unavailable due to Control Mode?
    • B
      Bradley RobertsSep 23, 2025
      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.

    What should I do if the changeover temperature on my Johnson Controls Fan is sensing a hot supply, but the controller is requesting cooling?
    • S
      Samantha ClarkSep 12, 2025
      First, verify that the supply is not in heating mode. If it is, nothing can be done from the TEC. Check the wiring of the supply temperature sensor or switch. Check the placement of the supply temperature sensor or switch. Verify that the changeover is set up correctly for the type of sensor attached (sensor or switch).

    How to troubleshoot Remote Zone Temp Fail on Johnson Controls TEC3000?
    • J
      josephramosSep 2, 2025
      If your Johnson Controls Thermostat is showing a 'Remote Zone Temp Fail' message, the external zone temperature sensor is likely disconnected or has failed. Start by checking the sensor's wiring. If the disconnection was intentional, reset the sensors through the menu. If the issue continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.

    • J
      Jessica WileySep 3, 2025
      If your Johnson Controls Thermostat displays 'Heating Ineffective,' it means the Supply Air Temperature has not increased above the configured Supply Air Temperature Alarm Offset while heating has been active for at least the Supply Air Temperature Alarm Delay. Verify that the heating elements on the rooftop are functioning properly.

    What to do if my Johnson Controls Controller displays Changeover Fail?
    • A
      allisonkaufmanSep 23, 2025
      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 to do if Johnson Controls TEC3000 shows Supply Fan Fault?
    • A
      amy17Aug 27, 2025
      If your Johnson Controls Thermostat displays 'Supply Fan Fault', it means the Supply Fan Status configured for either BI1 or BI2 has not proved within the configured Fan Alarm Delay. To resolve this: 1. Verify that the Supply Fan is operating when turned on. 2. Verify that the Supply Fan Status wiring is connected correctly.

    Why does my staged equipment cycle too fast or slow with PID on my Johnson Controls Controller?
    • M
      Ms. Angela DeleonSep 18, 2025
      If the staged equipment on your Johnson Controls Controller cycles too rapidly or slowly when the PID is running, the control band around the setpoint is likely set incorrectly for your equipment, zone, or preference. Verify that the equipment's minimum on/off times are set correctly. If the default deadband doesn't provide the desired temperature control, set Temp Control Setup to Deadband Override and adjust the Deadband parameter to your preferred value.
