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 first 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 4th change
1) The indoor fan runs at the set speed when processing in sleep mode, after the first 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 first
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
first.
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.
8.4 The indoor fan motor works as below while RT meets the set temperature to stop compressor:
