* You can set the temperature for AUTO, COOL, and DRY modes within 
the range of 18-30°C.

Notes:

 Operations modes other than the temperature setting will be the 

same at the last time operation was stopped, so Cooling → Dry→ 

Cooling → Dry type of operations cannot be automatically set.

 If you set the ON timer and OFF timer on the same time, the air 

conditioner will run the ON timer. If two ON timer are set at the 

same time, the air conditioner will run in the order of the program 

number.

 If there is a power interruption, such as due to a power outage 

during the WEEKLY timer setting or a circuit breaker cutting out, 

the internal timer of the air-conditioning will be incorrect. (See page 

9 "Auto-restart".) In such a case, the main timer lamp will notify 

you of this by flashing, so carry out matching of the time and date. 

(See page 2 "remote controller preparation".)

 You cannot use the WEEKLY timer together with the other timers. 

If you want to run the product on WEEKLY timer after using the ON/

OFF Timer, Program Timer, or SLEEP Timer while the WEEKLY 

timer is running, you need to activate the WEEKLY timer again.
