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.
1.3.5 Dehumidifier Mode
1.3.5.1 Indoor fan speed is fixed at low and cannot
be changed
1.3.5.2 All protections are activated and operate the
same as they do in cooling mode.
1.3.5.3 The louver operates the same as in cooling
mode.
1.3.6 Timer function
1.3.6.1 The timing range is 24 hours.
1.3.6.2 Timer On. The machine turns on
automatically at the preset time.
1.3.6.3 Timer Off. The machine turns off
automatically at the preset time.
1.3.6.4 Timer On/Off. The machine turns on
automatically at the preset On Time, and then turns
off automatically at the preset Off Time.
1.3.6.5 Timer Off/On. The machine turns on
automatically at the preset Off Time and then turns
off automatically at the preset On Time.
1.3.6.6 The timer does not change the unit
operation mode. If the unit is off now, it does not
start up immediately after the “timer off” function is
set. When the setting time is reached, the timer
LED switches ioff and the unit running mode
remains unchanged.
1.3.6.7 The timer uses relative time, not clock time.
1.3.7 Sleep function
1.3.7.1 The sleep function is available in cooling,
heating, or auto mode.
1.3.7.2. The operational process for sleep mode is
as follows:
When cooling, the temperature rises 1℃ (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
fixed at auto speed. Anti-cold wind function takes
priority.
