2. Only when remote control signal is switched to indoor ambient
temperature display status (corresponding remote control code:
10) from other display status (corresponding remote control code:
00, 01,11),controller will display indoor ambient temperature for 3s
and then turn back to display set temperature.
Under this mode, indoor fan operates at set fan speed.
Compressor, outdoor fan, 4-way valve and electric heating tube
stop operation. Indoor fan can select to operate at high, medium,
low or auto fan speed. Temperature setting range is 16~30
O
C.
(12)Off-peak energization function:
Adjust compressors minimum stop time. The original minimum
stop time is 180s and then we change to:
The time interval between two start-ups of compressor cant be
less than 180+Ts(0≤T≤15). T is the variable of controller. Thats to
say the minimum stop time of compressor is 180s~195s. Read-
in T into memory chip when refurbish the memory chip each time.
After power recovery, compressor can only be started up after
180+T s at least.
(13) SE control mode
The unit operates at SE status.
(14) X-fan mode
When X-fan function is turned on, after turn off the unit, indoor fan
will still operate at low speed for 2min and then the complete unit
will be turned off. When x-fan function is turned off, after turn off
the unit, the complete unit will be turned off directly.
(15) 8
O
C heating function
Under heating mode, you can set 8
O
C heating function by remote
controller. The system will operate at 8
O
C set temperature.
(16)Turbo function
Turbo function can be set under cooling and heating modes.
Press Fan Speed button to cancel turbo setting. Turbo function is
not available under auto, drying and fan modes.
(17)Auto cleaning function(only available on some models)
The automatic cleaning function of the indoor heat exchanger
can be dedusted and sterilized by the condensation, frosting,
defrosting and
high temperature stages of the evaporator.
1.Under the power off,press and hold the “Internal Clean” button
for 3 seconds while holding down the “MODE” and “FAN” buttons
for 5 seconds to turn on the Auto Clean function. After the function
is turned on, the air conditioner displays “CL”.
2. The evaporator will be rapidly cooled or heated during the
automatic cleaning process. There may be noise or even noise.
The noise generated by the plastic parts due to thermal expansion
and contraction is normal. During the cleaning and disinfection
process, the room temperature may increase slightly, please keep
the room well ventilated.
Tips:
The automatic cleaning function can only be started under normal
environmental conditions. If the indoor environment is easy to
dust, it is recommended to clean it once a month. If the indoor
environment is not so dusty, it is recommended to clean it once
every three months.
After turning on the automatic cleaning mode, the user can leave
the room. When cleaning is complete, the unit will automatically
enter standby mode.

Outdoor Unit
1. Cooling mode:
Working condition and process of cooling mode:
①
When Tindoor ambient temperature≥Tpreset, unit enters into
cooling
mode.
Indoor
fan,
outdoor
fan
and
compressor
start
operation. Indoor fan operates according to set fan speed.
②
When Tindoor ambient temperature≤Tpreset-2
℃
, compressor
stops
operation
and
outdoor
fan
will
stop
30s
later.
Indoor
fan
operates according to set fan speed.
③
When Tpreset-2
℃<
Tindoor ambient temperature
<
Tpreset,
unit operates according to the previous status.
Under cooling mode, 4-way valve is not energized. Temperature
setting
range
is
16~30
℃
.
If
compressor
stops
because
of
malfunction in cooling mode, indoor fan and swing motor will work
according to the original status.

>
Tpreset, unit will be in
drying mode. Outdoor fan and compressor start operation while
indoor fan will operate at low fan speed.
②
When Tpreset-2
℃
≤Tindoor ambient temperature≤Tpreset, unit
operates according to the previous status.
③
When
Tindoor
ambient
temperature
<
