1.12 Other Functions

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.
1.12.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.12.3 Indoor Unit ON/OFF Button
An ON/OFF button is provided on the display of the unit.
<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 113 for detail.
Note: When the ON/OFF button is pressed for 10 seconds or more, the forced cooling operation is
stopped.
1.12.4 Photocatalytic Deodorizing Filter
The photocatalytic deodorizing filter powerfully decomposes odor of tobacco, pet, etc. The
deodorizing power is regenerated simply by being exposed to the sunshine. It is recommended
to dry the filter in the sun for about 6 hours (after vacuuming the filter) every 6 months.
1.12.5 Air-Purifying Filter
The air-purifying filter collects tobacco smoke, pollen, etc. with electrostatic agency.
This filter includes a deodorizing active carbon filter that removes minute particles of odor.
Replace the air-purifying filter every 3 months.
1.12.6 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.
