This is the case immediately after the main power supply switch is turned on and
means that the user interface is in normal condition. This continues for 1 minute.
This is to prevent refrigerant from remaining in the compressor. The unit will stop
after 5 to 10 minutes.
This is because the crankcase heater is warming the compressor so that the
compressor can start smoothly.
Several different indoor units are being run on the same system. When another
unit is running, some refrigerant will still flow through the unit.
