30sec; after another 60sec，the compressor will run. The indoor run indicator light will blink while defrosting. When the compressor
has run for 6min or Ttub≥10℃, the compressor will stop, the four-way valve will open after 30sec and the run indicator will stop
blinking. After another 90sec, the compressor and outdoor fan will resume running and the indoor fan will run in anti-cold-wind

1. The condition and process of AUTO mode
◆Cooling Tset=25℃，Heating Tset=20℃.
◆ If T amb>Tset +1℃, COOL mode will act. At this time the hidden set temperature is 25℃. If T amb≤Tset -2℃, the compressor
and outdoor fan will stop, the indoor fan will run at the set speed; if Tset-2℃＜Tamb≤Tset+1℃, the unit will keep running in
the original mode.
◆If Tamb≤Tset+2℃, HEAT mode will act. At this time the hidden set temperature is 20℃. If Tamb≥Tset+4℃, the compressor
will stop, the outdoor fan will delay 30sec to stop and the indoor fan will run at low speed; if Tset+2℃＜Tamb＜Tset+4℃, the unit
will keep running in the original mode.
◆ If 22℃＜Tamb＜26℃, FAN mode will act. The displayed temperature is 23℃.
2. Protection function：
