2.13 Other Functions
2.13.1 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.
The cold air blast is prevented using similar control when defrost control starts or when the
thermostat is turned ON.
2.13.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal receiving
sound.
2.13.3 Indoor Unit ON/OFF Switch
ON/OFF
switch is provided on the display of the unit.
Press
ON/OFF
switch once to start operation. Press once again to stop it.
ON/OFF
switch 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
ON/OFF
switch for 5 to 9 seconds while the
unit is not operating.
Refer to page 199 for details.
Forced cooling operation is not started if
ON/OFF
switch is pressed for 10 seconds or more.
2.13.4 Auto-restart Function
If a power failure (even a momentary one) occurs during the operation, the system restarts
automatically in the same conditions as before when the power supply is restored to the conditions
prior to the power failure.
It takes 3 minutes to restart the operation because 3-minute standby function is activated.
