ć
(32~99
̧
). If outdoor ambient temperature is
received, the display remains the same. If valid control signal is received, it will display set temperature for 5s and then resume
displaying ambient temperature.
For units with memory function, set temperature will be displayed after re-energizing the unit.
10. Cold Plasma Function
Turning on the cold plasma function with remote controller when the fan operates, this function will act. Turning off the cold plasma

12. Comfortable and energy-saving function (this function is realized by setting energy-saving signal with remote controller.
Please refer to corresponding part of remote controller in instruction manual)
①
Comfortable and energy-saving function is only valid under cooling mode. After setting is succeeded, set temperature of indoor unit
is 27°C(81°F), and indoor unit displays “SE”.
②
After setting is succeeded and compressor operates, fan speed is adjusted automatically according to below condition:
When Tamb.≥32°C(90°F), indoor fan operates at super-high speed;
When 32°C(90°F),>Tamb.≥Tpreset
＋
2°C(3~4°F),, indoor fan operates at high speed;
When Tpreset
＜
Tamb
. ＜
Tpre
et ＋
2°C(3~4°F),, indoor fan operates at medium speed;
When Tamb.≤Tpreset, indoor fan operates at low speed.
After setting is succeeded and compressor operates, the unit operates at low speed.
③
There should be at least 3min and 30s operation time for the switchover among high speed, medium speed and low speed.
④
After entering into energy-saving mode and When Tamb. ≥28°C(82°F),, horizontal louver operates at fix-angle position 4. 10min
later or Tamb. <28°C(82°F), or after receiving the changing order for swing angle, horizontal louver will operate the angle set by
remote controller.
⑤
Other requirement and protection is same as that under cooling mode.
⑥
If set energy-saving function again under energy-saving mode, it will exit energy-saving mode.
