1.12 Other Functions

1.12.1 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 lowers to
ensure 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.
1.12.2 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.
 Press this button once to start operation. Press once again to stop it.
 This button is useful when the remote controller is missing or the battery is dead.
 The operation mode refers to the following table.
<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 183 for detail.
Note: When the ON/OFF button is pressed for 10 seconds or more, the forced cooling operation is
stopped.
1.12.4 Titanium Apatite Photocatalytic Air-Purifying Filter
This filter combines the Air-Purifying Filter and Titanium Apatite Photocatalytic Deodorizing Filter as
a single highly effective filter. The filter traps microscopic particles, decomposes odors and even
deactivates bacteria and viruses. It lasts for 3 years without replacement if washed about once
every 6 months.
1.12.5 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.

Up to 4 timer settings can be saved for each day of the week (up to 28 settings in total).
