1.11.1 Hot-Start Function
In order to prevent the cold air blast that normally occurs when heating operation starts, 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.
1.11.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal receiving
sound.
1.11.3 Indoor Unit ON/OFF Button
An
ON/OFF
button is provided on the display of the unit.
Press the
ON/OFF
button once to start operation. Press once again to stop it.
The
ON/OFF
button is useful when the remote controller is missing or the battery has run out.
<Forced cooling operation>
Forced cooling operation can be started by pressing the
ON/OFF
button for 5 to 9 seconds while
the unit is not operating.
Refer to page 103 for detail.
Note:
When the
ON/OFF
button is pressed for 10 seconds or more, the forced cooling operation is
stopped.
1.11.4 Auto-restart Function
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.
