1.8.1
Hot Start Function
In order to prevent the cold draft that normally comes when heating operation starts, the
temperature of the indoor heat exchanger is detected, and either the air flow is stopped or is
made very weak thereby carrying out comfortable heating of the room.
*The cold draft is also prevented using a similar control when the thermostat turns OFF.
1.8.2
Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.8.3
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
controller is missing or if its battery has run out.
Pressing the ON/OFF button cycles through the following operation modes: cooling

OFF
→
heating

OFF
→
cooling, etc. Since the operation mode is not displayed, you have to
judge what mode the unit is in by feeling whether the air coming out of the vent is cold or hot.
The operation mode refers to the following table.
1.8.4
Titanium Apatite Photocatalytic Air-Purifying Filter
This filter combines the Air Purifying Filter and Titanium Apatite Photocatalytic Deodorizing
Filter in a single highly effective unit. The filter traps microscopic particles, decompose odours
and even deactivates bacteria and viruses. It lasts for three years without replacement if
washed about once every six months.
1.8.5
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.
1.8.6
Self-Diagnosis Digital Display
The microcomputer continuously monitors operating conditions of the indoor unit, the outdoor
unit, and the entire system. When an abnormality occurs, the remote controller displays error
code on the LCD. These indications allow prompt maintenance operations.
1.8.7
Auto-restart Function
Even if a power failure (including one for just a moment) occurs during the operation, the
operation restarts in the condition before power failure automatically when power is restored.
(Note) It takes 3 minutes to restart the operation because the
3-minutes standby
function is
activated.
