The radiation temperature sensor can adjust airflow direction and airflow volume if there is a big
difference between the radiation temperature and setting temperature.
The Discharge Air Thermistor prevents a
perception of a cold draft at cooling operation.

● Radiation Sensor
By setting “Floor HEAT Control” in an instance where there is a big difference between radiation
temperature and setting temperature, the operation is as below:
1. Warm air is discharged downward to increase airflow volume.
1)
2. When increased temperature reaches the setpoint, the airflow volume and airflow direction will return
to the default setting position.
2)
NOTICE
The effect of this function is dependent on the size of the room and air-conditioning load.
● Discharge Air Thermistor
1) When there is human activity in a room, the air flows horizontally during the “Avoid Air” setting.
2) When 60 minutes have passed after starting this function and the setpoint is not reached, the
setting will return to the default setting.
NOTE:
• Set “HIGH”, “MED” and “LOW” airflow volume in advance on the wired controller. Depending on the
setting, the discharged air temperature is controlled by adjusting the air conditioning capacity. (Discharged
air temperature is increased in order of “HIGH”, “MED”, “LOW”.)
• This function may not be effective depending on the unit’s operating condition, for example if multiple
indoor units are operating at the same time.
• Depending on the cold draft control setting, it may take longer to cool the entire room.
