  If you receive a SENSOR FAULT indicating a broken sensor on your CaptiveAire Fan, it means the temperature sensor isn't reading the temperature correctly or is shorted. Verify the wiring to terminals TxA and TxB on the board, as well as the wiring to the sensor. If the wiring is correct, replace the sensor with a 10Kohm thermistor.

  If you're getting an OVER AMP FAULT on your CaptiveAire Fan, it could be due to several reasons. The fan speed might be too high, so try reducing the RPM. Also, check the motor wiring against the wiring diagram on the fan motor to ensure it's correct. Lastly, the overload in the VFD might be set too low, so set it to the motor's FLA value.

Why isn't my CaptiveAire Fan cooling the room properly?
- A
  Angela RobertsAug 29, 2025
  If the room temperature is too warm and your CaptiveAire Fans aren't cooling, the fan activation temperature might be set too high; try reducing it. Also, ensure the fan is spinning counter-clockwise when viewed from the floor in cooling mode. Finally, make sure equipment or storage items aren't blocking the airstream under the fan.

  Timothy HayesSep 19, 2025
  If your CaptiveAire Fan is in SYSTEM BYPASS, it means that all fans are running at BMS speed because System Bypass has been turned on. You need to fix the reason why System Bypass was enabled and then turn system bypass off on the ECPM03 menu.
