11.5 Timer Control
11.5.1 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.
