Other Functions

1.11.1 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.
1.11.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.11.3 ON/OFF Button on Indoor Unit
An ON/OFF switch is provided on the front panel of the unit. Use this switch when the remote
controller is missing or if its battery has run out.
Every press of the switch changes from Operation to Stop or from Stop to Operation
1.11.4 Photocatalytic Deodorizing Filter
Photocatalytic Deodorizing Filter demonstrates powerful oxidation characteristics when
subjected to harmless ultraviolet light. Photocatalytic deodorizing power is recovered simply by
exposing the filter to the sun for 6 hours once every 6 months.
1.11.5 Air-Purifying Filter
A double structure made up of a bacteriostatic filter and an Air-Purifying Filter traps dust,
mildew, mites, tobacco smoke, and allergy-causing pollen. Replace the Air-Purifying Filter once
every 3 months.
1.11.6 Mold Proof Air Filter
The filter net is treated with mold resisting agent TBZ (harmless, colorless, and odorless). Due
to this treatment, the amount of mold growth is much smaller than that of normal filters.
