12.7 Powerful Mode Operation

When the powerful mode is selected, the internal setting temperature will shift lower up to 2°C (for Cooling/Soft
Dry) or higher up to 3.5°C (for Heating) than remote control setting temperature for 20 minutes to achieve the
setting temperature quickly.

12.8 Timer Control

There are 2 sets of ON and OFF timer available to turn the unit ON or OFF at different preset time.
If more than one timer had been set, the upcoming timer will be displayed and will activate in sequence.
12.8.1 ON Timer Control
ON timer 1 and ON timer 2 can be set using remote control, the unit with timer set will start operate earlier than
the setting time.
This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate 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 operate earlier than the set time as shown below.
12.8.2 OFF Timer Control
OFF timer 1 and OFF timer 2 can be set using remote control, the unit with timer set will stop operate 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.
This control can be omitted by open the circuit of JP1 at indoor unit printed circuit board.
