Automatic mode
When controller selects an automatic working mode, the indication light twinkles for 20
seconds and the air-conditioner does not start working until the working mode to be selected
by the system; The air-conditioner automatically selects one of the cooling, dehumidification,
and heating mode as the working mode according to the indoor air temperature .
①
When TA ≥ 27
℃
, the controller enters into the cooling mode and follows the mode in working.
The setting temperature herein is 24
℃
and the air-conditioner runs according to the setting
wind speed;
②
When 20
℃
<TA<27
℃
, the controller enters into the dehumidification mode and follows the
mode in working. The setting temperature is 24
℃
and the air-conditioner runs according to
the setting wind speed;
③
When TA ≤ 20
℃
, the controller enters into the heating mode and follows the mode in
working (The cooling only type follow the ventilation mode). The setting temperature herein is
24
℃
and the air-conditioner runs according to the setting wind speed;
④
This mode includes the functions of timing, sleeping, auto-restart(optional), negative
ion(optional),I feel
（
optional
）
;
⑤
The system mode will not change along with the variety of the indoor temperature after
being selected. The new working mode will be selected again after air-conditioner turns off or
mode switch.
⑷
Cooling mode
The setting temperature shall be fixed by the remote control. The temperature-controlling
range is 16
℃
- 32
℃
. The setting temperature can be adjusted through the button of “+” “-”.
The setting wind speed can be adjusted through the button of “wind speed selection” in the
selection of the four wind speeds type, such as strong wind, high wind, low wind and mute
wind. The four-way valve always is closed under this mode. The other action is as following:
①
When TA - TS ≥ 1
℃，
after the compressor meet the 3 minutes delay protection, the
compressor and the outdoor fan start running;
② When TA = TS ， maintain the previous status;
③ When TA - TS ≤ -1 ℃， after the compressor meet the 3 minutes protection condition, the
compressor and the outdoor fan turn off;
④ The setting wind speed can be adjusted by the remote control during the ongoing cooling
process, and the interior fan still retains working;
⑤ When the status of TE ≤ 0 ℃ last for 10 seconds and the compressor keeps working for
above than 5 minutes, turn off the compressor and outdoor fan, the indoor fan keep working
according to the setting wind speed; Quit from such protection if TE
≥ 7 ℃ ;
⑥ This mode includes the functions of timing, sleeping, auto-restart (optional), negative ion
(optional), I feel （ optional ） ;
⑦ When the cooling ongoing ， the button of the “Swing” can control the swing and stop of the
horizontal air-blade;
⑧ Automatic wind-speed control ：
TA - TS ≥ 3 ℃， wind-speed works at high wind;
TS +1 ℃ ≤ TA ＜ TS +3 ℃， wind-speed works at middle wind;
TA – TS ＜ 1 ℃， wind-speed works at low wind;
Without 3 minutes delay when the wind speed turns into the high wind from the low wind,
