● Model RC-E5
(1) Switching sequence of the operation mode switches of remote control
(2) CPU reset
This functions when "CHECK" and "ESP" buttons on the remote control are pressed simultaneously. Operation is
same as that of the power source reset.
(3) Power failure compensation function (Electric power source failure)
• This becomes effective if "Power failure compensation effective" is selected with the setting of remote control
function.
• Since it memorizes always the condition of remote control, 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 (f), (g) and (h) are memorized regardless whether the power failure compensation is effective or not while the setting of silent mode is
cancelled regardless whether the power failure compensation is effective or not.
At power failure – Operating/stopped
(a)
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.)
Operation mode
(b)
Air flow volume mode
(c)

However, the stop position (4-position) is cancelled so that it returns to Position (1).
"Remote control function items" which have been set with the remote control function setting ("Indoor
(f)
function items" are saved in the memory of indoor unit.)
Upper limit value and lower limit value which have been set with the temperature setting control
(g)
Sleep timer and weekly timer settings (Other timer settings are not memorized.)
