mode, the setting temperature falls by 2℃，the setting temperature display on the panel is invariable.
c)After another one hour running period, to cooling mode, the temperature rises by another 1℃，to
heating mode, the temperature falls by another 2℃.
d) When sleeping function runs for more than 7 hours, the system turns off.
e) If the setting temperature is going to be reset, the setting temperature during running process
changes accordingly.
f) The timing close function and sleeping function can be set simultaneously. The corresponding
function will be effective depending on its setting time’s precedence.
●The indoor coil protection function(anti-freezing and anti over-heated protection)
a)When under cooling(dehumidifying)，the controller detects the indoor coil temperature for
confirming the validity of starting anti-freezing protection：
A、If TE＜TE8 and last for 2 minutes，the compressor and outdoor fan unit close for starting the
anti-freezing protection, meanwhile, the cooling indication light twinkles and displays E4.
B、if TE＞TE9 or it’s over than 6 minutes since the moment compressor turns off，the
anti-freezing protection quit, the compressor and outdoor fan unit restart.
b)When under heating, the controller detects the indoor coil temperature for confirming the validity of
starting overheating protection：
A、if TE≥TE10 and last for 5 seconds，the outdoor fan unit close and start the indoor coil
overheating protection meanwhile with the twinkling light of the heating mode indication light, and
continuously detect the indoor coil temperature.
B、if TE＞TE11 and last for 10seconds，compressor turns off and display E5.
C、During the above protection period，if TE≤TE12，the overheating protection quits and restores
the former working condition.
●Up and down swing control function
a)The swing angle after being primarily electrified is 140°in the opening direction，and runs 160°in the
close direction.
b)When the air-conditioner turns on, the air swing angle is 140°in the opening direction(if without the
barrier of the structure, the actual stop position is 120°)，and stop to the horizontal position in a
90°angle(return back by 30° ), which is the automatic setting stopping position if there is no swing
function being selected；If being controlled by the remote controller, the air swing shall stops at the
position selected by the remote controller（The five positions on the remote controller are in
accordance with the position range from 50°to 100°indicated in the below picture；If the continue
swinging mode is selected, the air swing will run continuously between the position from 55°to 105°.
c) In case of the incorrectness of the swing angle due to the impact of the mechanical resistance during
operation period, the maximum swing angle shall be 140°every one hour, and return back by 30°so as
