will 3 minutes of idle mode. If the compressor senses the incoming wind temperature is higher
than 23 after it stops for 15 minutes, the unit will switch to cooling mode. Otherwise it will
keep the heating mode.
Enter into the cooling mode and follow the cooling process( supposed temperature 26 ).
Compensation temperature difference will be cancelled automatically. When the temperature
is high enough to stop the compressor, the compressor stops and there will be 3 minutes for
idle mode. If the compressor senses the incoming wind temperature is equal to or below 23
after it stops for 15 minutes, the unit will switch to heating mode. The compensation
temperature will be added automatically. Otherwise it will keep the cooling mode.
When the unit switches from other modes to automatic mode, if the work state changes (judge
first and then work), there will be 3 minutes for idle mode. Ant then the temperature will change
to the judged level according to the incoming wind temperature.
8. Trial running
The indicated frequency for trial running is 58Hz, wind volume is strong.
The trial running will last for 30 minutes and then the unit will be powered off. The
unit will exit the trial running if it receives any remote-control signal during the trial
running period.
There is no low work-intense running protection.
9. Low Work-intense protection control
Specification for heat-exchange termperature sensor
B fixed number=3700 R(25 )= 10KO
Under the cooling /moisture removing modes,the low work-intense protection will
be carried out according to the heat-exchange temperatures as shown in the table
below.

Low Work-intense protection control will be neglected in the trial running.
Low Work-intense protection control will be cancelled for 3 minutes temporarily
after the powerful cooling starts for 1 minute

10. High Work-intense protection control
Under the heating mode, the high work-intense protection will be carried out
