1.13.1 Hot Start Function
Heat Pump Only
In order to prevent the cold air blast that normally comes when heating is started, the
temperature of the heat exchanger of the indoor unit is detected, and either the air flow 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 gets turned ON.
1.13.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.13.3 ON/OFF Button on Indoor Unit
An ON/OFF button is provided on the front panel of the unit. Use this button when the remote

and even deactivates bacteria and viruses. It lasts for three years without replacement if
washed about once every six months.

For FTKD25/35D, FTK(X)E25/35B, FLK(X)25-60A
Photocatalytic Deodorizing Filter demonstrates powerful oxidation characteristics when
