NS SPLIT INSTALLATION MANUAL

Troubleshooting

Standard Microprocessor Controls

To check the unit control board for proper operation:

1.Disconnect thermostat wires at the control board.

2.Jumper the desired test input (Y1, Y2, W, O or G) to the R terminal to simulate a thermostat signal.

3.If control functions properly:

•Check for thermostat and field control wiring (use the diagnostic inputs mode).

4.If control responds improperly:

•Ensure that component being controlled is functioning (compressor, blower, reversing valve, etc.).

•Ensure that wiring from control to the component is functioning (refer to the LED Definition table below and use the diagnostic outputs mode).

•If steps above check properly, replace unit control.

Refrigerant Systems

To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Compare the change in temperature on the air side as well as the water side to the tables on pages 26-27. If the unit’s performance is not within the ranges listed, and the airflow and water flow are known to be correct, gauges should then be installed and superheat and subcooling numbers calculated. If superheat and subcooling are outside recommended ranges, an adjust- ment to the refrigerant charge may be necessary.

Notes: Refrigerant tests must be made with desuperheater turned “OFF”. Verify that air and water flow rates are at proper levels before servicing the refrigerant circuit.
