
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.
14.5.1 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.
