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.
• When the air-conditioner is used together with burners, thoroughly
ventilate the area. Insufficient ventilation can result in accidents due to
oxygen 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
temperature 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
temperature 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 sometimes
rotates to eliminate extra heat generated by the electric heater, etc.
The fan speed comes to low or high.

Basic operations
Pressing the
button will change the operation mode in the following order.
*1: Not all functions are available on all models of indoor units. Functions that are not available will not
appear on the display.
*2: The preset temperature for AUTO (either single or dual set point) mode will appear depending on
the indoor unit model.
AUTO (dual set point) mode:
In AUTO (dual set point) mode, the preset temperatures can be set for cooling and heating, and
operation can be switched automatically between cooling and heating depending on the room
temperature.
The preset temperatures for cooling and heating set in AUTO (dual set point) mode will be reflected
to the temperature setting for COOL and HEAT modes.
SETBACK mode:
The SETBACK function automatically switches the operation mode between cooling and heating to
maintain the room temperature within the set temperature range.
The preset temperatures for cooling and heating set in SETBACK mode can be different from the
preset temperatures for other modes.
