8-2-2. DRY Operation
(The Remote Controller 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-
2-5. (Fan speed is AUTO only.)
• The outdoor fan motor operates as described in
Table 8-1-3, and the compressor motor speed
according to the operation command signal sent
from the indoor unit.
NOTE :

8-2-3. Heating Operation
Transferring of heating operation signal from indoor
unit to outdoor unit starts.
The indoor fan motor operates by the room tempera-
ture when selecting “AUTO” of “FAN” as shown in
Fig. 8-2-6, and operates with a set air flow when
selecting “Low ” to “High ”.
However, to prevent cold draft, revolution speed of
the fan is restricted by indoor heat exchanger when
air flow is AUTO (Fig. 8-2-7) and starting of FAN
Manual.
