This mode has the following three setting methods:
· ON timer operation : Timer only star ts the air conditioner.
· OFF timer operation : Timer only stops the air conditioner.
· ON/OFF timer operation: Timer both starts and stops the air conditioner.
2) Daily timer mode
Operation of this mode is the same as that of the 1 day timer mode. However, timer operation can be set to the same time each day in accordance
with the set ON/OFF timer time. (ON/OFF timer each 1 time/daily)
3) Auto off timer mode
The OFF timer can be easily set in 30-minute units. (30 minutes to 4 hours range) When the remaining time reaches 0:00, the air conditioner stops.
When the Auto off timer mode is selected, the next time the air conditioner is started, the OFF timer operates automatically so that the timer can be

When ON/OFF operation from the central controller, etc. was restricted when timer operation was set, the set ON/OFF timer is not executed. After the
restriction is removed, timer operation is performed at the ON/OFF time.
When ON/OFF operation was restricted during AUTO OFF timer operation, the remaining time at the point operation was restricted is memorized and the
air conditioner is stopped after the memorized remaining time from the time the restriction was removed.
