1.3.4 Auto Mode
This mode can be selected with the remote
controller and the temperature setting can be
adjusted between 17°C~30°C
In auto mode, the machine selects cooling, heating,
or fan-only mode on the basis of
ΔT (ΔT =T1-Ts).
T1-Ts
Cooling
Heating*
Fan only
Heating*: In auto mode, cooling only models run the
fan.
Indoor fans run at the auto fan speed of the relevant
mode.
The louver operates the same as in relevant mode.
If the machine switches mode between heating and
cooling, the compressor pauses for a certain
period of time intermittently and then selects a
mode based on T1-Ts.
If the setting temperature is modified, the machine
selects a new running function.

℃
(to not
higher than 30
℃
) every hour. After 2 hours, the
temperature stops rising and the indoor fan is fixed
to auto speed.
When heating, the temperature decreases 1
℃
(to
not lower than 17
℃
) every hour. After 2 hours, the
temperature stops decreasing and the indoor fan is
