Dehumidifying Operation - Sanyo SPW-D253GH56 Service Manual

2-16 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 between +2 deg. and -2 deg. of the set temperature.
ROOM TEMP.
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. 22 for details.
C range: When the room temperature is in this range, the microprocessor shuts off the air
conditioner.
