1.4.18 Airflow Setting when Heating Thermostat is OFF
This setting is used to set airflow when heating 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).
 When thermostat OFF airflow volume up mode is used, careful consideration is required before
deciding installation location.
1.4.19 Setting of Operation Mode to AUTO
This setting makes it possible to change differential values for mode selection while in automatic
operation mode, only when the wireless remote controller or any central remote controller is
connected.
The automatic operation mode setting is made by the use of the "Operation Mode Selector" button.
1.4.20 Auto Restart after Power Failure
Mode
12 (22)
When the "Auto Restart after Power Failure" setting is turned OFF, all the units will remain OFF
after power failure, or after the main power supply is restored. When this setting is turned ON
(factory setting), the units that were operating before the power failure will automatically restart
operation after power failure, or after the main power supply is restored.
