Applications
The networked TEC3000 Series Thermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or
N2 networked devices. Wireless networked models of the TEC3000 Series Thermostat Controller are also
available. Proportional Fan Coil and Individual Zone Thermostat Controllers 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 an on/off or floating control input
The networked models feature a field-selectable Building Automation System (BAS) BACnet MS/TP or N2
communication capability that enables remote monitoring and programming for efficient space temperature control.
The wireless models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that
enables communication with a building automation system (BAS). 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 onboard touchscreen UI with backlit display that makes setup and operation quick
and easy. For Single-or Two-Stage Economizer Thermostat Controller models, only the single-speed fan
configuration is supported. For TEC3x1x and TEC3x2x models, multiple fan configurations are supported for fan
coil equipment types, as follows:
• 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/or 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 causes Fan Lock on Johnson Controls Thermostat and how to resolve it?
    • D
      David DickersonAug 27, 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 does my Johnson Controls Fan controller display 'Idle' with a 'Heating Unavailable' status due to Control Mode?
    • B
      Brandon MartinezSep 7, 2025
      If your Johnson Controls Fan controller displays 'Idle' with a 'Heating Unavailable' status because of the control mode, it means the control mode is set to Cooling Mode, but the controller is requesting heating. Change the control mode to Auto or Heating.

    Why is Heating Ineffective on my Johnson Controls TEC3322-1 Controller?
    • A
      Angela MaySep 18, 2025
      If your Johnson Controls Controller indicates 'Heating Ineffective,' it means the supply air temperature hasn't increased above the configured Supply Air Temperature Alarm Offset, even though heating has been active for at least the Supply Air Temperature Alarm Delay. To resolve this, verify that the heating elements on the rooftop are functioning properly.

    How to fix Outdoor Temp Fail on Johnson Controls TEC3322-1 Controller?
    • A
      Arthur MarshSep 13, 2025
      If you are experiencing an Outdoor Temp Fail error with your Johnson Controls Controller, it means the external outdoor air temperature sensor is either disconnected or has failed. Here's what you can do: 1. Check the sensor's wiring. 2. If the sensor was intentionally disconnected, reset the sensors through the menu. 3. If the issue continues, you should order replacement units and return the faulty devices to Johnson Controls under the RMA program.

    Why does the Johnson Controls Fan controller show an error when trying to upgrade the firmware?
    • K
      Kristina PatrickSep 9, 2025
      If the Johnson Controls Fan controller shows an error when trying to upgrade the firmware, it means the firmware on the USB drive is below the minimum required version (Error code 1025). Use firmware version 3.0.2.xxxx (for networked models) or 2.0.2.xxxx (for wireless models) or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.

    What does it mean when my Johnson Controls Controller displays an Open Window error?
    • J
      Jose LeeSep 15, 2025
      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.
