1.10 Other Functions

1.10.1 Hot-Start Function
In order to prevent the cold air blast that normally comes when heating operation is started, the
temperature of the indoor heat exchanger is detected, and either the airflow is stopped or is
made very weak thereby carrying out comfortable heating of the room.
*The cold air blast is also prevented using a similar control when the defrosting operation is
started or when the thermostat is turned ON.
1.10.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.10.3 Indoor Unit ON/OFF Button
An ON/OFF button is provided on the display of the unit.
<Forced operation mode>
Forced operation mode can be started by pressing the ON/OFF button for 5 to 9 seconds while
the unit is not operating.
Refer to "Forced operation mode" on page 42 for detail.
Note: When the ON/OFF button is pressed for 10 seconds or more, the forced operation is stopped.
1.10.4 Auto-restart Function
Even if a power failure (including one for just a moment) occurs during the operation, the
operation restarts automatically when the power is restored in the same condition as before the
power failure.
Note: It takes 3 minutes to restart the operation because the 3-minute standby function is activated.
