NINE Timing
The highest timing should be 24h,1min as unit,can’t cancel timing at the single timing
and no change to mode and indicator light run when timing has been made.

、
Timing for being off
Can only work the timing function which fall within the range from 1min to 24h when
air-conditioner run and then will shut down when the timing is over.
2
、
Timing for being on
Can only work the timing function which fall within the range from 1min to 24h when
air-conditioner shut down and then will run when the timing is over.
The former timing and sleep functions will be canceled automaticly when you intend to run or
shut down after timing.

9. The Protection Function Of Fault Instruction
1 、 The over-current protection:
total current ≥ 9A the compressor stops;
8A ≤ total current <9 A the compressor reduce operating frequency, if the current is
still more than 8A when the frequency is down to 35 Hz, then the
compressor will stop to work;
7A ≤ total current <8 A in this area the compressor prohibit from increasing the frequency;
The overall current <7A in this area the compressor operate normally

Anti-freeze protection of indoor coil while cooling and dehumidification
Te decline:
if 5 <Te <9 ,
