(2) CPU reset
This functions when “CHECK” and “ESP” buttons on the remote controller are pressed simultaneously. Operation is same as
that of the power supply reset.
(3) Power failure compensation function (Electric power supply failure)
• This becomes effective if “Power failure compensation effective” is selected with the setting of remote controller function.
• Since it memorizes always the condition of remote controller, it starts operation according to the contents of memory no
sooner than normal state is recovered after the power failure. Although the auto swing stop position and the timer mode are
cancelled, the weekly timer setting is restored with the holiday setting for all weekdays.
After recovering from the power failure, it readjusts the clock and resets the holiday setting for each weekday so that the
setting of weekly timer becomes effective.
• Content memorized with the power failure compensation are as follows.
Note (1) Items

regardless whether the power failure compensation is effective or not.
➀
At power failure – Operating/stopped
If it had been operating under the off timer mode, sleep timer mode, the state of stop is memorized. (Although the
timer mode is cancelled at the recovery from power failure, the setting of weekly timer is changed to the holiday
setting for all weekdays.)

However, the stop position (4-position) is cancelled so that it returns to Position (1).
➅
“Remote controller function items” which have been set with the remote controller function setting (“Indoor
function items” are saved in the memory of indoor unit.)
➆
Upper limit value and lower limit value which have been set with the temperature setting control
