1.12.1 Hot-Start Function
In order to prevent the cold air blast that normally occurs when heating operation is started, the
temperature of the indoor heat exchanger is detected, and the airflow is either stopped or
significantly weakened resulting in comfortable heating.
Note:
The cold air blast is prevented using similar control when defrost control starts or when the
thermostat is turned ON.

When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
