NOTICE
Be sure to turn ON the power 6 hours before operation in order to have power
running to the crankcase heater and to protect the compressor.
Turn on the power supply of the compressor unit, heat exchanger unit, and all
indoor units. When the communication between the compressor unit, heat
exchanger unit, and indoor units is established and normal, the display indication
state will be as below (default situation when shipped from factory).
