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).

    Why does my Johnson Controls Thermostat display Partial Restore Complete?
    • S
      Samuel ThompsonAug 30, 2025
      If your thermostat displays 'Partial Restore Complete' when restoring from a backup, it means not all items in the backup file were restored. This can happen if a value is outside the acceptable range or if there are inconsistencies in a setting's reliability. To resolve: 1. Create a Backup file on a USB drive for the TEC that is showing the issue. 2. Edit the backup file created in the previous step on a PC to reflect the desired settings. 3. Verify that the modified values are within minimum and maximum range in the backup file. 4. Restore the settings from the newly edited backup file on the TEC.

    What to do if Supply Temp Fail appears on Johnson Controls Thermostat?
    • D
      Dana MayoAug 25, 2025
      A 'Supply Temp Fail' message indicates that the external supply temperature sensor is either disconnected or has stopped working. To resolve this: 1. Check the sensor's wiring. 2. If the disconnection was intentional, go to the menu, then Control Setup, and select Inputs to reset the sensors and clear the fault. 3. If the issue persists, it may be necessary to order replacement units and return the affected devices to Johnson Controls under the RMA program.

      ymooreSep 3, 2025
      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.

    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.

    • J
      Jeffrey LoganAug 28, 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.

    What does it mean when my Johnson Controls Fan indicates 'Dirty Filter'?
    • E
      Elizabeth RogersSep 9, 2025
      If your Johnson Controls Fan indicates 'Dirty Filter', it means equipment connected to the BI configured for a Dirty Filter alarm is triggering the alarm. Replace the filter in the equipment as explained in the manufacturer's instructions.

    What causes the Johnson Controls Fan to display 'Zone Temperature Too Hot' and how do I fix it?
    • J
      James SuttonSep 5, 2025
      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 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.
