Field Settings for Indoor Unit SiUS342303E
171 Part 5 Field Settings and Test Operation
Due to the aforementioned, when the "Auto restart after power failure” setting is ON, be careful for
the following situations that may occur.
1.4.21 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).

1. The air conditioner will start operation suddenly after power failure,
or when the main power supply is restored. The user might be surprised
and wonder why the air conditioner turned ON suddenly.

units are in operation, the units will automatically start operation
(the fan will rotate) after the power supply is restored due to completion
of the maintenance work.
