Part 2 Functions & Controls
2.3 Healthy Dehumidification operation
• When the dehumidification operation is set by the remote controller, the intake air temperature is detected and the set-
ting temp. is automatically set according to the intake air temperature.
• When intake air temp. is 1 C(2 F) above the setting temp., condition of compressor is same as in cooling mode operation.
• When intake air temperature reaches 1 C(2 F) below the setting temp., compressor operates in step1~step3 and the
indoor fan speed again operates at low speed or comes to a stop.
2.4 Automatic operation
• When the Auto operation is set by the remote controller, the intake air temperature is detected and the setting temp. is
automatically set according to the intake air temperature and operation mode.
• The air volume is automatically set according to the intake air temperature.
2.5 Auto changeover operation
• The air conditioner changes the operation mode automatically to keep indoor temperature steady.
• When room temperature vary over ±2°C(±4°F) with respect to setting temperature, air conditioner keeps the room tem-
perature in ±2°C(±4°F) with respect to setting temperature by changing the mode from cooling to heating and vice
versa.
