1.6.5 Evaporator Temperature Protection
• When T2> TEstop, the compressor frequency will
cease operation until T2< TEH2.
• When TEdown<T2< TEstop, the compressor frequency
will decrease to the lower level
• When REH2<T2< TEstop, the compressor will keep
running at the current frequency.
• When T2< TEH2, the compressor will not limit the
frequency and resume to the former frequency.
1.7 Auto-mode
• This mode can be selected with the remote controller .
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of
∆
T (

Heating*: In auto mode, cooling only models run the fan
• The louver operates same as in relevant mode.
• If the machine switches mode between heating and
cooling, the compressor will keep stopping for 15
minutes and then choose mode according to T1-Ts.
• If the setting temperature is modified, the machine will
choose running function again.
1.8 Drying mode
• Indoor fan speed is fixed at breeze and can’t be
changed. The louver angle is the same as in cooling
mode.
• All protections are active and the same as that in
cooling mode.
1.9 Forced operation function
• Forced cooling mode:
The compressor and outdoor fan continue to run and
the indoor fan runs at low speed. After running for 30
minutes, the AC will switch to auto mode with a preset
temperature of 24°C.
• Forced auto mode:
Forced auto mode operates the same as normal auto mode
with a preset temperature of 24°C.
• The unit exits forced operation when it receives the
following signals:
• Switch on
• Switch off
• Timer on
• Timer off
• Changes in:
• mode
• fan speed
• sleeping mode

1.10 Timer function
• Timing range is 24 hours.
• Timer on. The machine will turn on automatically
when reaching the setting time.
• Timer off. The machine will turn off automatically
when reaching the setting time.
• Timer on/off. The machine will turn on
automatically when reaching the setting “on” time,
and then turn off automatically when reaching the
setting “off” time.
• Timer off/on. The machine will turn off
automatically when reaching the setting “off” time,
and then turn on automatically when reaching the
setting “on” time.
• The timer function will not change the AC current
operation mode. Suppose AC is off now, it will not
start up firstly after setting the “timer off” function.
And when reaching the setting time, the timer LED
will be off and the AC running mode has not been
changed.
• The setting time is relative time.
• The AC will quit the timer function when it has
malfunction.
1.11 Sleep function
• The sleep function is available in cooling, heating, or
auto mode.
• The operational process for sleep mode is as follows:
• When cooling, the temperature rises 1°C (less than
30°C) every hour. After 2 hours, the temperature
stops rising and the indoor fan is fixed at low
speed.
• When heating, the temperature decreases 1°C(
more than 17°C) every hour. After 2 hours, the
temperature stops decreasing and the indoor fan is
fixed at low speed. Anti-cold wind function takes
