8-2-3. DRY Operation
(The Remote Control MODE Button is
Set to the DRY Position)
• Once the setting is made, the operation mode is
memorized in the microcomputer so that the
same operation can be effected thereafter simply
by pushing [START/STOP] button.
• Dry operation signal is transmitted to outdoor
unit.
• The Cooling operation giving priority to dehumidi-
fying, which restrains the indoor fan speed and
compressor motor speed, is performed.
• The indoor fan motor operates as shown in Fig.
8-2-6. (Fan speed is AUTO only.)
• The outdoor unit controls the outdoor fan relay
R01, R02 and R03, and the compressor motor
speed according to the operation command
signal sent from the indoor unit.

(1) Dehumidifying-preferential Cooling capacity
control
• The cooling capacity and room temperature
are controlled by changing the compressor
motor speed according to both the difference
between the temperature detected by the
room temperature sensor and the temperature
set by TEMP button and also any change in
room temperature.
• The compressor operates with maximum 28
rps for 1 minute when started and restarted.
• When the air conditioner operates in Dry
mode, the maximum compressor motor speed
is restricted.

While multiple indoor units operate, compres-
sor motor speed is calculated in the outdoor
unit to operate.
• When room temperature is lower than set
temperature, indoor fan motor is operated at
fan speed SUL as shown in Fig. 8-2-6 while
the outdoor unit stops.
• ECONO. mode cannot be set.
• Other controls than the above-mentioned
controls are common to those of Cooling
operation.
8-2-4. Auto Operation
• The operation mode is selected according to the
outdoor temperature when Auto operation has
started, as shown in Fig. 8-2-7. The Fan only
mode will continue until the operation mode is
selected. The air flow display on the remote
control becomes AUTO.
Fig. 8-2-7
• If the compressor is turned off by room tempera-
ture or outdoor temperature for 15 minutes
consecutively after operation mode has been
selected, the operation mode is selected again.
• In Powerful Cool mode, the louver directs down-
ward, and air flow increases. When room tem-
perature comes close to the set temperature, the
louver returns to Cooling operation position.
• The other controls than the above-mentioned
controls follow that of each operation.
