Auto restart
When power returns after a power supply failure, the auto restart function
reapplies the user interface settings at the time of the power failure. Therefore, it
is recommended to always enable the function.
If the preferential kWh rate power supply is of the type that power supply is
interrupted, always enable the auto restart function. Continuous indoor unit
control can be guaranteed independent of the preferential kWh rate power supply
status, by connecting the indoor unit to a separate normal kWh rate power supply.
