OPERATION
Sequence of Operation
a) The indoor fan runs at the set speed when processing sleep mode, after the 1st change, unit runs at low
speed, and after the 2nd change, unit runs at low-low speed ( if AC without low-low speed, it runs at low
speed instead). 10 hours later AC quits from sleep mode and runs at former set fan speed .
b) In SLEEP mode, the vane works according to the preset, after the rst change, vane blade works at cold
air prevention angle. 10 hours later AC quits from sleep and works as the former preset.
c) The set fan speed refers to the preset value before processing SLEEP mode. If the unit just on stand by
before sleep operation, the set value to be according to low speed . If AC preset in super speed, the set
value will change to high speed, while in Auto wind, it will change to low speed.
B. Sleep mode on Heating operation:

The 1st change The 2nd change The 3rd change
The 4th change
1) The indoor fan runs at the set speed when processing in sleep mode, after the rst change, unit changes to
medium speed if the preset is in high operation, and the medium and low speed preset will keep the original even
after the rst change. 10 hours later AC quits from sleep mode and runs at former set fan speed
2) Processing SLEEP mode, the vane works according to the preset, 10 hours later AC quits from sleep and works as
the former preset.
3) The set fan speed refers to the preset value before processing SLEEP mode. If the unit just on stand by before
sleep operation, the set value to be according to low speed. if AC preset in super speed, the set value will change to
high speed, while in Auto wind, it change to low speed.
Sleep process control
1) If the set temperature is changed during the period of sleep mode, it is also executed as the initial sleep set, and
the change time is reset to 0, the temperature change will be restarted, but the 10 hours running time will not be
reset as 0, it will accumulate continuously.
2) The fan speed can not be changed during sleep mode.
3) During the sleep period in cooling mode, the new set will be executed if the vane work status is changed, the anti-
cold angle will not be executed.
4) During the sleep period in heating mode, the wind speed and vane swinging for cold air prevention function is
selected rst.
The sleep instruction in Cooling or Heating of I FEEL mode
1) The current set temperature is set as initial value if sleep mode has not been set before processing sleep mode.
2) If the set temperature is changed, the change times is reset to 0, the new set temperature will be executed, 10
hours timing will be continued.
3) There is other operation during sleep mode, e.g. vane operation, AC keeps operation continuously with the initial
value no exchanged.
4) The sleep mode category is changed during sleep operation, the initial set temperature in cooling or heating of I
FEEL mode will be set as initial running value if no temperature adjustment; or the temperature after increased or
decreased will be set as initial running value after temperature adjustment; and the change times is reset to 0, 10
hours timing accumulation will be restarted.
5) The unit works according to the new set temperature when operating remote controller or other controller to quit sleep
mode.
7. Auto Restart Function (Optional) .
7.1 PCB with auto restart function will keep the operation parameters in EEPROM even with power off. And the unit
can restore operation as the former status automatically while power is on.
7.2 The status parameters include the set mode, fan speed, set temperature and the vane blade position when unit
is off (the swinging status will be remembered when the vane was set as swinging)
7.3 Pressing sleep button 10 times within 8 seconds during running status, the Auto Restart Function could be
activated or turned off; The buzzer sounds 3 times BIBI when activated and 4 times BIBI when function is turned off
(operate with remote controller).
8. ECO function
8.1 The adjustable temperature: 16°C-31°C or 61°F-88°F.
8.2 The action temperature and running of compressor is the same as cooling mode.
8.3 The fan speed setting and other assistant function same as cooling mode.
