Dry Operation - Toshiba RAS-M10NKV-E Service Manual

2) Changing of air flow (Fan setting : AUTO)
When the Hi POWER is started, the fan of the
indoor unit operates at higher air flow level than
normal air flow AUTO (normal air flow AUTO
is shown in Fig. 6-2-2). Because of the
difference between room temperature and set
temperature are increased automatically.
3) Changing of air flow (Fan setting : One of 5
levels)
When the Hi POWER is started, the fan of the
indoor unit operates at higher consecutive air
flow level. (Fan speed on the display of remote
control does not change)
4) Changing of louver position
If the room temperature is higher than setting
temperature by 3.5 °C or more, the louver is
automatically set to the maximum air flow
position. If it is not, position of louver is not
change. When room temperature is reach to
setting temperature. The louver moves back
to set position.
(11) Quiet operation control.
When the [QUIET] button is pushed, the fan is
restricted the revolution speed at L- level until
the [QUIET] button is pushed once again
(cancel QUIET operation).
Remarks :
QUIET operation is appropriate to work with
less cooling load condition. Because of the
fan speed L- may cause not enough the
cooling capacity.

6-2-3. 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 [ ] 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.
6-2-7. (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.
• When the air conditioner operates in Dry mode, the
maximum compressor motor speed is restricted.
M10 : Max. 20 rps
M13 : Max. 20 rps
M16 : Max. 22 rps
While multiple indoor units operate, compressor
motor speed is calculated in the outdoor unit to
operate.
• When room temperature is lower than set tempera-
ture, indoor fan motor is operated at fan speed SUL
as shown in Fig. 6-2-6 while the outdoor unit stops.
• ECONO Hi POWER, QUIET and COMFORT-
SLEEP mode cannot be set.
• Other controls than the above-mentioned controls
are common to those of cooling operation.
