1.3.21 Airflow Setting when Cooling Thermostat is OFF
This is used to set airflow to LL airflow when cooling thermostat is OFF.
If the airflow setting when thermostat is OFF is set to 03: OFF, the air in the indoor unit will be
stagnant and suction air thermistor may not detect room temperature correctly, resulting in
problems that thermostat will not be ON easily.
Use optional remote sensor in such conditions, or set the field setting 10 (20)-2 to 03 (only remote
controller thermistor).
