Heating mode
⑺
The default temperature is determined by the remote control and to be within the range of 16 ℃ - 32 , ℃
which can be adjusted by the button of “+” and “-”. Press the button of “fan speed selection” for
choosing the wind speed from the four gears of strong fan, high fan, low fan and mute fan. The other
conditions are as following, when:
① TA-3-TS ≤ -1 ℃， if after three minutes delay time as for protection purpose, the compressor and the
outdoor fan start, the indoor fan works in cold-wind prevention condition, the TA shown on the digital
display has 3
℃ temperature compensation.
② TA-3-TS ≥ 1 ℃， if the compressor last continuously running for 3minutes, the compressor and the
outdoor fan stop, the indoor fan keeps on working under anti cold-wind condition. The TA shown on
the digital display has 3
℃ temperature compensation.
③ TA-3=TS ， retain the previous status ；
④ Automatic wind speed control, when:
TA ＜ TS ， wind speed in high fan ；
TS ≤ TA ＜ TS +2 ℃， wind speed in middle fan ；

the start of the compressor; Low down TS to be
＜ TA-3 ， then the compressor turns off immediately
without the restriction condition of 3 minutes protection delay;
The mode includes the functions of timing, sleeping, auto ⑦ -restart (optional), negative ion (optional),
I feel （ optional ）
