FAULT Digital Display Phenomenon
PG abnormity “E4” AC stopped
TA abnormity “E1” AC stopped
TE abnormity “E3” AC stopped
After the indoor motor electrified, if there is no impulse signal feedback by the indoor
motor detected within 10 seconds, cut off the output voltage supplied to the indoor fan
from the controller. After 30seconds waiting time, re-electrify the indoor fan. If still has
no impulse signal feedback by the indoor motor being detected within 10 seconds, the
controller stays in waiting and the digital display indicates the corresponding fault
code is E4.Turn off the air-conditioner by remote control, and the fault display will not
show.
(14)The definition to swing angle of the air door
Picture 3 shows the swing angle of the step motor of E series wall-mounted type
air-conditioner under 4.8kW (Except 4.8 kW);
①
Once being electrified, the air door effect a motion of total closed, and the swinging speed
is 22°/s
；
②
After the air-conditioner turns on, the air door effect a motion of total opening, and swing to
the corresponding primary position. The primary position for heating mode is the position
5(Picture 3), for cooling mode is the position 2 (Picture 3).
③
The air door “Swing” on the remote control can set the swinging mode to be automatic
swing or hand swing
；
④
The maximum swing angle of automatic swing under heating mode is 50°
，
e.g. the angle
between position 3-5 in picture 3
；
the angle under cooling mode is 50°e.g. the angle between
position 2-4 in picture 3
；
The swinging speed is 5.5°/s
；
⑤
After the air-conditioner being turned on and electrified, if the air door is not set “Swing”,
the swing angle will swing to the corresponding position according to the different modes. For
example: the corresponding position under cooling mode is position 2(Picture 3), heating
mode is position 5(Picture 3). The air door resumes the automatic swing after the fan starts. If
the setting swing mode is hand swing, the swing angle will never change
；
⑥
After turning off the air-conditioner and stopping the running of the indoor fan, the air door
shut off automatically;
⑦
Enter into the automatic mode by pressing the Emergency button, the air door opens after
the setting mode of the system starts. Before the starting of the setting mode, the air door
parks at the datum mark of cooling mode.
The below picture shows the swing angle of E type:
