8-2-2. 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 [ ] button.
•
Dry operation signal is transmitted to outdoor unit.
•
The Cooling operation giving priority to
dehumidifying, 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 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.

8-2-3. Heating operation
Transferring of heat operation signal from indoor unit to
outdoor unit starts.
The indoor fan motor operates by the room
temperature when selecting "AUTO" of "FAN" as shown
in Fig. 8-2-7, 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. 8-2-8) and starting of FAN Manual.
