Applications
The TEC3000 Series Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers are wireless
networked devices that provide control of the following:
• local hydronic reheat valves
• pressure-dependent variable air volume (VAV) equipment with or without local reheat
• two- or four-pipe fan coils
• cabinet unit heaters
• other individual zone equipment using a proportional 0 to 10 VDC control input
The networked models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that
enables remote monitoring and programming for efficient space temperature control. All models include a USB port
configuration that reduces installation time by allowing simple backup and restore features from a USB drive, which
enables rapid cloning of configuration between like units.
Some models have occupancy sensing capability built into the device. These thermostat controllers maximize up to
30% energy savings in high-energy usage commercial buildings, such as schools and hotels, during occupied
times by using additional standby setpoints.
All models feature an intuitive UI with backlit display that makes setup and operation quick and easy. Multiple fan
configurations are supported for fan coil equipment types:
• single-speed
• multi-speed (two or three discrete speeds)
• variable-speed/EC motors (0 to 10 VDC control)
Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan coil units with or
without reheat. When no heating is required, the thermostat controller monitors space humidity and activates
dehumidification control as necessary. Heat and reheat is used as required to maintain the space temperature. For
optimal dehumidification performance, use a fan coil unit that has a multi-speed or variable-speed fan (VSF).

    What does Supervisory Status = Offline mean on my Johnson Controls Controller?
    • R
      Robert BoyleSep 23, 2025
      If your Johnson Controls Controller displays 'Supervisory Status = Offline', it indicates that the supervisory controller isn't communicating with the TEC, the TEC isn't mapped to a JCI Supervisory System, or the WNC Gateway isn't communicating with the TEC. To resolve this: 1. Map the TEC into a JCI Supervisory system. 2. Verify that the PAN’s WNC Gateway is online. 3. Add ZFR Pro Routers/Repeaters into the wireless system.

    Why are some icons hidden on my Johnson Controls TEC3011 Controller?
    • E
      Eric RileySep 23, 2025
      If some icons are hidden on your Johnson Controls Controller, it's because lockout levels are in use or the icons are hidden due to the display settings. See Table 5 for lockout levels and access details.

    What to check if Johnson Controls TEC3011 says Zone Temperature Too Hot?
    • D
      Dr. Shannon BuckleyAug 31, 2025
      If your Johnson Controls Controller reports that the zone temperature is too hot, it means the zone temperature has exceeded the configured Zone Temp High Limit. You should verify that the TEC and the RTU cooling are enabled and working properly.

    What to do if I see Remote Zone Temp Fail on Johnson Controls Controller?
    • J
      James WrightAug 25, 2025
      The 'Remote Zone Temp Fail' error on your Johnson Controls Controller indicates that the external zone temperature sensor is either disconnected or has failed. To resolve this: 1. Check the wiring of the sensor to ensure it is properly connected. 2. If the sensor was intentionally disconnected, reset the sensors through the menu. 3. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.

    How do I troubleshoot a Supply Temp Fail error on my Johnson Controls Controller?
    • J
      John MorrowAug 26, 2025
      A 'Supply Temp Fail' error on your Johnson Controls Controller means that the external supply temperature sensor is either disconnected or has failed. Here’s how you can troubleshoot it: 1. Check the wiring of the sensor to ensure it is properly connected. 2. If the sensor was intentionally disconnected, 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.

    Why is the Econ Unavailable on my Johnson Controls TEC3011?
    • A
      April GreenAug 26, 2025
      If your Johnson Controls Controller displays 'Econ Unavailable', it means the outdoor air temperature sensor is either not installed, has failed, or has been disconnected, preventing the controller from managing the economizer. To fix this, follow the same steps as for an Outdoor Temp Fail alarm: * Check the wiring of the sensor. * If intentionally disconnected, reset sensors through the menu. * If problems persist, order replacement units and return the affected devices to Johnson Controls under the RMA program.

    Why are OA Lockouts Disabled on my Johnson Controls TEC3011 Controller?
    • L
      Laura BarrettAug 27, 2025
      If OA Lockouts are disabled on your Johnson Controls Controller, it means the local outdoor air temperature sensor has become disconnected or failed, or a network outdoor air temperature sensor has timed out. As a result, the controller is no longer shutting down equipment based on the OA lockout setpoints. Here's what to do: 1. If the outdoor air temperature source was a locally connected sensor, follow the troubleshooting steps for the Outdoor Temp Fail alarm. 2. If the outdoor air temperature source was a BAS, check the BAS to ensure it's online and providing the TEC with temperature readings. If you intentionally removed the BAS mapping, reset sensors through the menu.

    Why does my Johnson Controls Controller display 'Cooling Unavailable due to OA Temp' or 'Heating Unavailable due to OA Temp'?
    • H
      Heather HernandezAug 27, 2025
      If your Johnson Controls Controller displays 'Idle' with a unit status of 'Cooling Unavailable due to OA Temp' (despite being above the cooling setpoint) or 'Heating Unavailable due to OA Temp' (despite being below the heating setpoint), it means the outdoor air temperature is either too warm for heating or too cold for cooling. To resolve this: 1. Adjust the Cooling and Heating Lockout Setpoints if they are inadequate. 2. Alternatively, wait for the outdoor conditions to become more suitable for heating or cooling.

    What should I do if my Johnson Controls TEC3011 shows a Dirty Filter alarm?
    • C
      Carol SchultzAug 28, 2025
      If your Johnson Controls Controller is showing a 'Dirty Filter' alarm, it means that the equipment connected to the BI configured for this alarm is triggering it. The solution is to replace the filter in the equipment, following the instructions provided by the manufacturer.

    How do I fix a Fan Lock error on my Johnson Controls TEC3011?
    • S
      Sean WilsonAug 28, 2025
      If you're getting a 'Fan Lock' error on your Johnson Controls Controller, it means 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. Here’s how to address it: 1. Check the equipment to ensure the fan is working correctly. 2. Use an ohmmeter to check the sensor's functionality and verify the wiring to the TEC. 3. Reset the fault by going to the menu, selecting 'Fault Status,' and then selecting 'Fan Lock'. 4. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
