ƒWhen TE 24°C continues for 5 minutes, the compressor stops.

It is the same status as the normal thermostat- OFF without error display.

The compressor restarts after approx. 2 minutes 30 seconds and this intermittent operation is not abnormal.

In case that the status in item ƒ generates frequently, stain on filter of the suction part of the indoor unit is considered.

Clean the filter and then restart the operation.
