This is the case immediately after the main power supply switch is turned on and
means that the remote controller is in normal condition. This continues for one
minute.
8.12 The Compressor in the Outdoor Unit does not Stop after
a Short Heating Operation
!
This is to prevent oil and refrigerant from remaining in the compressor. The unit will
stop after 5 to 10 minutes.

Unit has stopped
!
This is because the crankcase heater is warming the compressor so that the
compressor can start smoothly.
