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 to do if Johnson Controls Thermostat provides an error when trying to upgrade firmware?
    • B
      Brandon RamosAug 31, 2025
      If your controller shows an error (Error code 1025) when upgrading firmware, it means the firmware on the USB drive is below the minimum required version. Please 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.

    Why are some icons hidden on my Johnson Controls Fan display?
    • C
      Chase NewtonSep 12, 2025
      If some icons are hidden on your Johnson Controls Fan display, it's likely due to lockout levels or display settings. See Table 6 for details on lockout levels and access.

    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.

    Why does my Johnson Controls Controller say 'Cooling Unavailable due to Control Mode' or 'Heating Unavailable due to Control Mode'?
    • S
      smithmarySep 15, 2025
      If your Johnson Controls Controller displays 'Idle' with a unit status of 'Cooling Unavailable due to Control Mode' (even when above the cooling setpoint) or 'Heating Unavailable due to Control Mode' (even when below the heating setpoint), it indicates that the control mode setting is incorrect. Here’s what you should do: * 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'.

    Why does my Johnson Controls heat pump heat when it should cool, and cool when it should heat?
    • K
      Kenneth SinghSep 22, 2025
      If your heat pump heats when it should be cooling, and cools when it should be heating, it indicates that the reversing valve polarity is set incorrectly. To fix this, consult the equipment documentation to verify the correct reversing valve polarity, and then adjust the Reversing Valve Polarity menu option accordingly.

    What to do if Johnson Controls Thermostat shows Dirty Filter?
    • J
      Joanna PearsonAug 29, 2025
      If your thermostat displays a 'Dirty Filter' alarm, it means that 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 does Cooling Ineffective mean on Johnson Controls Thermostat?
    • A
      Alexander WebbAug 29, 2025
      If your Johnson Controls Thermostat displays 'Cooling Ineffective', 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.
