• The fan operation functions to circulate the air in the room.
• The temperature of the room cannot be set by fan operation.
Caution:
Never expose your body directly to cool air for a long time. Excessive expo-
sure to cool air is bad for your health, and should therefore be avoided.
Dry operation
The dry is a microcomputer-controlled dehumidifying operation which controls ex-
cessive air-cooling according to the room temperature of your choice. (Not usable
for heating.)
1. Until reaching room temperature of your choice
The compressor and indoor fan function is linked motion according to the change
of the room temperature and automatically repeat ON/OFF.
2. When reaching room temperature of your choice
Both the compressor and indoor fan stop.
When stop continues for 10 minutes, the compressor and indoor fan are oper-

Regarding displays during heating operation "DEFROST"
Displayed only during the defrosting operation.
"STAND BY"
Displayed from the start of heating operation until the moment warm air blows out.
Caution:
• When the air-conditioner is used together with burners, thoroughly venti-
late the area. Insufficient ventilation can result in accidents due to oxy-
gen deficiency.
• Never place a burner at a place where it is exposed to the airflow from the
air-conditioner.
Doing so can result in imperfect combustion of the burner.
• The microcomputer functions in the following cases: *
• Air does not blow out when heating starts. *
- To prevent any cool air from escaping, the indoor fan is gradually switched in
sequence from faint airflow/weak airflow/set airflow according to the tempera-
ture rise of the blown out air. Wait a moment until the airflow comes out naturally.
• The fan is not moving at the set speed. *
- In some models, the system switches over to faint airflow when the temper-
ature of the room reaches the set temperature. In other cases, it stops to
prevent any cool air from escaping during the defrosting operation.
• Air flows out even if operation is stopped. *
- Approximately 1 minute after the stop of operation, the indoor fan some-
times rotates to eliminate extra heat generated by the electric heater, etc.
The fan speed comes to low or high.
* Except PEFY-P-NMHU-E-F.

3.3. Room temperature adjustment

To change room temperature
Press the 1 [Set Temperature] Button and set the room temperature of your
choice.
Pressing or once changes the setting by 1 °C.
If the pressing is continued, the setting continues to change by 1 °C.
• Indoor temperature can be set within the following range.
Cooling/dry :19 °C - 30 °C
Heating :17 °C - 28 °C
• Temperature cannot be set for the fan mode.
* The range of room temperature display is 8 °C - 39 °C. Outside this range, the
display flashes either 8 °C - 39 °C to inform you if the room temperature is
lower or higher than the displayed temperature.

3.4. Fan speed adjustment

To change fan speed
Every time you press the 6 [Fan Speed] button once, it switches from the low-
speed to high-speed settings successively.
In the electronics dry operation, the indoor fan automatically turns to low-speed
operation. Switching of fan speed is impossible. (Only the display on the remote
controller changes.)
* Every time the fan speed adjustment button is pressed once, the fan speed is changed.
