12.7 Powerful Mode Operation
When the powerful mode is selected, the internal setting temperature will shift lower up to 35.6°F (for
Cooling/Soft Dry) or higher up to 38.3°F (for Heating) than remote control setting temperature for 20 minutes to
achieve the setting temperature quickly.
12.8 Timer Control
12.8.1 ON Timer Control
ON Timer can be set using remote control, where the unit with timer set will start operation earlier than the setting
time. This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set ON time, indoor (at fan speed of Lo-) and outdoor fan motor start operation for 30
seconds to determine the indoor intake air temperature and outdoor air temperature in order to judge the
operation starting time.
From the above judgment, the decided operation will start operation earlier than the set time as shown below.
12.8.2 OFF Timer Control
OFF Timer can be set using remote control, the unit with timer set will stop at set time.
12.9 Auto Restart Control

three to four minutes (there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be
selected randomly) after power supply resumes.
This type of control is not applicable during ON/OFF Timer setting.
