Abstract
A method is disclosed for identifying when a compressor is being run in reverse due to improper wiring. In a preferred embodiment, sensors sense the condition of a refrigerant at the inlet line and a refrigerant at the outlet line. If an expected pressure differential is not seen, then the determination is made that the compressor is running in reverse. In embodiments the control system may shut down the compressor, provide an alarm, or reverse a phase of two of the three wires of a three phase power input to correct the rotation direction.
