A927_O: DLT Sensor Open
On the VSODC, this fault would be displayed on the seven-segment LED as a number 16. A 16 displayed is one of several inverter faults. You will need to validate this fault at the EcoNet Thermostat or by looking at the red or yellow flashing LED's in the upper right quadrant of the drive itself
The Drive LED's will be flashing the Red LED 3 times.
The DLT or Discharge Line Sensor is a thermistor connected on the compressor discharge tube and is wired back directly to the drive itself. This fault indicates that the sensor is either defective or loose. Please check the resistance of the discharge sensor against the temperature resistance chart after making sure it was not just simply loose or unplugged from the drive.
