Refer to the QuickLIT website for the most up-to-date version of this document.
Applications
The TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers are stand-alone and
field-selectable BACnet® MS/TP or N2 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 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.
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. 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/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 does 'Zone Temp Unreliable' mean on my Johnson Controls TEC3610 Controller?
    • J
      jensenkristinSep 14, 2025
      If your Johnson Controls Controller displays 'Zone Temp Unreliable', it means all sources of zone temperature, including the onboard sensor, are unreliable. You will need to order replacement units and return the affected devices to Johnson Controls under the RMA program.

    How to fix a 'Remote Zone Temp Fail' error on a Johnson Controls TEC3610?
    • T
      Timothy EvansAug 25, 2025
      If your Johnson Controls Controller displays 'Remote Zone Temp Fail', it means the external zone temperature sensor is either disconnected or has failed. First, check the sensor wiring. If you intentionally disconnected it, reset the sensors through the menu. If the issue persists, you may need to order replacement units and return the faulty devices to Johnson Controls under the RMA program.

    How to troubleshoot a 'Supply Temp Fail' error on a Johnson Controls TEC3610?
    • R
      Randy SmithAug 26, 2025
      If your Johnson Controls Controller displays 'Supply Temp Fail', the external supply temperature sensor is either disconnected or has failed. You can try these steps: First, check the sensor wiring. If intentionally disconnected, reset the sensors by going to the menu, then Control Setup, and selecting Inputs. If the problem continues, order replacement units and return the affected devices to Johnson Controls under the RMA program.

    Why is the TEC3000 zone temperature not changing fast enough on my Johnson Controls TEC3610?
    • C
      Connor JonesAug 27, 2025
      If the TEC3000 zone temperature on your Johnson Controls Controller isn't changing fast enough compared to a calibrated sensor, it might be because the TEC3000 is set up for larger spaces by default when a proportional device is active. To resolve this, go to Control Setup > Tuning > Equipment Size and select 'Oversized'.

    Why does my Johnson Controls Controller show an error when backing up settings?
    • K
      Karen GeorgeSep 15, 2025
      If the controller provides an error when trying to back up settings on your Johnson Controls Controller, it is possible that the USB drive is defective. Try a different USB drive.

    Why is the temperature displayed lower than actual on my Johnson Controls TEC3610?
    • E
      Erik YuSep 23, 2025
      If the temperature displayed on your Johnson Controls Controller is lower than the actual room temperature, cold air drafts may be entering the back of the TEC, or air may be forced through the TEC from a nearby vent. To fix this, seal any holes behind the TEC to reduce drafts, or move the location of the TEC or change the venting to prevent air from being forced through the TEC.

    What to check if the zone temperature is too hot on my Johnson Controls TEC3610 Controller?
    • T
      Tim NicholsSep 7, 2025
      If your Johnson Controls Controller displays 'Zone Temperature Too Hot', it means the zone temperature has exceeded the configured Zone Temp High Limit. To resolve this, verify that the TEC and the RTU cooling are enabled and functioning properly.

    What does 'Heating Ineffective' mean on my Johnson Controls TEC3610 Controller?
    • J
      Jessica StanleySep 8, 2025
      If your Johnson Controls Controller displays 'Heating Ineffective', it means the supply air temperature hasn't increased enough while heating has been active for the specified delay. To fix this, verify that the heating elements on the rooftop are functioning properly.

    What to do if there is an 'Internal Sensor Fail' on a Johnson Controls TEC3610 Controller?
    • J
      Joseph CaseySep 23, 2025
      If an internal sensor has failed on the TEC of your Johnson Controls Controller, order replacement units and return the affected devices to Johnson Controls under the RMA program.

    Why does my Johnson Controls TEC3610 show 'Fan Lock'?
    • R
      Richard StoutAug 31, 2025
      If your Johnson Controls Controller displays 'Fan Lock' and control has shut down, it means the switch connected to the BI configured for Fan Lock didn't sense airflow within 10 seconds of starting the fan. Here's how to address it: First, inspect the equipment to ensure the fan functions. Next, check the sensor functionality with an ohmmeter and verify the wiring to the TEC. Then, reset the fault by going to the menu, selecting Fault Status, and choosing Fan Lock. If the problem persists, you may need to order replacement units and return the affected devices to Johnson Controls under the RMA program.
