The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is fitted
to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase sequencer
operates, and the unit will not start. This device is located in the control box of the outdoor unit.
The following table shows the LED indicator light for phase protector under normal operation and fault conditions.
