Dehumidifying Operation
Dehumidifying operation uses the cooling cycle to remove moisture from the air, but by
running an indoor fan at a low speed, to dehumidify without greatly lowering room
temperature. In this mode, the microprocessor automatically controls the ON-OFF
operation b2 deg. and -2 deg. of the set temperature.
❑
The indoor fan speed is automatically set to L and cannot be adjusted to M or H.
❑
When the set temperature is either 18 or 19°C, the set temperature is considered the same
as 20°C.
❑
Room temperature is monitored every 8 minutes when it is in the B range to select the best
operation mode.

A range: When the room temperature is in this range, cooling operation starts. However, when
the temperature is below 18°C, the cooling operation does not start.
B range: When the room temperature is in this range, the air conditioner automatically repeats
the dehumidifying cycle of 5 minutes ON, 3 minutes OFF – see Fig. 20 for details.
C range: When the room temperature is in this range, the microprocessor shuts off the air
conditioner.
