1.11.1 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 is
made very weak thereby carrying out 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.

receiving sound.

1.11.4 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.
1.11.5 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.
