Fault Code FOU - Outdoor Sensor Failure

This indicates that the outdoor sensor is defective, shorted or open, or the outdoor temperature is below -40F. NOTE: The installer must choose YES in Function 12 to enable this feature. The unit will continue to operate when this error is displayed but the control will ignore the outdoor reset feature and run at the programmed temperature. The bottom line indicates the status of the pump.
