Symptom: The Display Shows "88; Symptom: The Compressor In The Outdoor Unit Does Not Stop After A Short Heating Operation; Symptom: The Inside Of An Outdoor Unit Is Warm Even When The Unit Has Stopped; Symptom: Hot Air Can Be Felt When The Indoor Unit Is Stopped - Daikin VRV IV+ RYYQ12U7Y1B Series Installer And User Manual

19.2.15 Symptom: The display shows "88"

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.
19.2.16 Symptom: The compressor in the outdoor
unit does not stop after a short heating
operation
This is to prevent refrigerant from remaining in the compressor. The
unit will stop after 5 to 10 minutes.
19.2.17 Symptom: The inside of an outdoor unit is
warm even when the unit has stopped
This is because the crankcase heater is warming the compressor so
that the compressor can start smoothly.
19.2.18 Symptom: Hot air can be felt when the
indoor unit is stopped
Several different indoor units are being run on the same system.
When another unit is running, some refrigerant will still flow through
the unit.
