1.16.1 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 the airflow is either stopped or made
very weak thereby carrying out comfortable heating of the room.
*The cold air blast is also prevented using similar control when the defrost control starts or when
the thermostat is turned ON.
1.16.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.16.3 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.
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.

When the [ON/OFF] button is pressed for 10 seconds or more, the forced cooling operation is
stopped.
1.16.4 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.
1.16.5 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.
