7-3. Hi POWER Mode
([Hi POWER] button on the remote
control is pressed.)
When [Hi POWER] button is pressed while the indoor
unit is in Auto, Cooling or Heating operation, Hi
POWER mark is indicated on the display of the remote
control and the unit operates as follows.
(1) Automatic operation
The indoor unit operates in according to the
current operation.
(3) Heating operation (NKHD Series only)
The preset temperature increases 2 °C,
(The value of the preset temperature on the
remote control does not change.)
The indoor unit operates in normal heating
mode except the preset temperature is higher
(+2 °C).
(4) The Hi POWER mode can not be set in Dry or Fan
only operation.
7-4. High-Temperature Limit Control
(NKHD Series only)
The microcontroller detects the indoor heat exchanger
temperature to prevent pressure of a refrigerating cycle
from increasing excessively.
The compressor and outdoor fan motor are controlled
as shown in Fig. 7-4-1.

7-5. Low-Temperature Limit Control
The microcontroller detects the indoor heat exchanger
temperature to prevent the indoor heat exchanger from
freezing.
The compressor and outdoor fan motor are controlled
as shown in Fig. 7-5-1 and 7-5-2.

(2) Cooling operation
•
The setting temperature drops 3°C.
(The value of the setting temperature on the
remote control does not change.)
•
If the room temperature is higher than the
setting temperature by 3.5°C or more, the
horizontal louver moves to the Hi POWER
position automatically. Then when the room
temperature is 1°C less than the setting
temperature the horizontal louver returns
automatically.
•
FAN speed : [AUTO]
If the room temperature is higher than the
setting temperature by 3.5°C or more, the air
conditioner operates at maximum airflow level.
If the room temperature is higher than the
setting temperature by less than 3.5°C, the air
conditioner operates at normal airflow level.
•
FAN speed : One of 5 levels
If the room temperature is higher than the
setting temperature by 3.5°C or more, the air
conditioner operates at higher consecutive
airflow level. If the room temperature is higher
than the setting temperature by less than 3.5°C,
the air conditioner operates at normal airflow
level.
