）
In heat mode, indoor fan speed control and anti cold wind function work as above chart.
；
（
2
）
When the compressor works, indoor fan doesn’t stop.
（
3
）
When indoor coil < 31°C, indoor fan works in low air flow mode.
（
4
）
If the indoor coil is still lower than 30°C after 2 minutes’ working, indoor fan works in low air flow
mode forcibly.
（
5
）
If the compressor works, before the indoor fan’s working, the indicator light
（
green
）
will flash
(0.5 second off, 1.5 second on).
d) Defrosting
：
：
：
：
In heat mode, if Te – Ta < 17°C and this condition last 1 minute (the compressor totally
working for44
minutes) , begin to defrost, the reversing valve, indoor fan stop, the compressor continue working.
。
Defrosting ending: if the defrosting last more than 6 minutes, defrosting ends, the reversing and outdoor fan
start to work, indoor fan work regarding to anti cold wind function.
In defrosting period, indicator light (green) flash (0.5 second off, 1.5 seconds on).
e) Auto
mode
：
：
：
：
1.
In auto mode, indoor fan works in low flow mode for 20 seconds, and then decide the working mode
regarding to the room temperature.
2.
The relationship of the working mode and the room temperature:
Ta Ta
≥
26°C
26°C > Ta
≥
21°C
Ta < 21°C
Mode COOLING
DEHUMIDIFYING
HEAT
NOTE
：
：
：
：
COOLING ONLY
：
：
：
：
Ta < 26°C working mode is dehumidifying mode.
3. If the air conditioner change to auto mode from cooling, heat, or dehumidifying mode, or the air
conditioner restart in auto mode one hour later, the unit will work as its pre mode. (under this situation,
indoor fan don’t work in low air flow mode.
f) Economic
mode
：
：
：
：
In economic mode, set temperature will rise 2°C in cooling
、
dehumidifying, while reduce 2°C in heat mode, and
the unit is in low flow forcibly, the fan speed can not change in economic mode.
