TIMER OPERATION
About the PROGRAM timer
● The PROGRAM timer allows you to integrate OFF timer
and ON timer operations in a single sequence. The se-
quence can involve one transition from OFF timer to ON
timer, or from ON timer to OFF timer, within a twenty-
four hour period.
● The first timer function to operate will be the one set near-
est to the current time. The order of operation is indi-
cated by the arrow in the remote control unit’s display
(OFF → ON, or OFF ← ON).
● One example of PROGRAM timer use might be to have
the air conditioner automatically stop (OFF timer) after
you go to sleep, then start (ON timer) automatically in
the morning before you rise.
About the ON timer
● The timer function is designed to bring your room to a
comfortable temperature by the set time; as a result, the
unit automatically begins operation before the set time
so that the room reaches the desired temperature by the
time set on the timer.
● The hotter it is in summer, or the colder it is in winter, the
earlier that operation will begin.
* During Heating Operation .......from 45 to 10 minutes be-
fore set time.
During Cooling/Dry Operation ... from 20 to 10 minutes be-
fore set time.
