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 lower frequency and
the indoor fan speed again operates at low speed or comes to a stop.
2.4 Auto changeover operation Heatpump Only
• 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.
