3.13 Function

 

Auto Mode

 

Under auto mode, the air conditioner will compare the room temperature with the setting temperature, 

automatically select the suitable operation. If auto mode operation is not suitable for you, it can select 

other operation mode.

 

 

Cool / Heat Mode

 

In the cool / heat mode, the temperature can be set.

 

When  it  is  the  cool  operation,  the  free  cooling

 

function  is  default  operated.  When  the  room 

temperature is high than 16°C,

 

the outdoor temperature is lower than 20°C, the humidity

 

is higher 

than  80%,    the  air  conditioner  will  switch

 

to  free  cooling

 

mode.  When  the  outdoor  temperature  is 

higher than 21°C,

 

or the humidity keep higher than 85% in 5 minutes,

 

the air conditioner will exit free 

cooling

 

mode with cool operation.

 

When it is the heat operation, the electric heater will be switch on till the room temperature is higher 

than the setting temperature.

 

 

Dry mode

 

The  unit  operates  in  the  fixed  temperature  which  is  15°C.

 

At  the  same  time,  the  indoor  fan  speed 

cannot

 

be adjusted.

 

 

Compressor delay 3 min protection

 

To protect

 

the compressor,

 

after the compressor turn off, the compressor turn on

 

after 3 minutes.

 

 

Power-down memory function

 

When the air conditioner re-connect to the power after power down, the unit will operate as the state 

before power down.

 

 

Dual units switch function

This function only is effective when setting the unit for main unit.

After se the dual units switch function, when switch time is up, if the formal main unit is operated, then 

the main unit will be closed, and operate the slave unit. If the formal slave unit is operated, then close 

the slave unit, operate the main unit. 

If when the operating the main unit has error, then the slave unit will be operated automatically. If the 

slave unit has error, then the main unit will be operated automatically.

High/Low Temp Cascade function

This function only is effective when setting the unit for main unit. After set the high/low function, when 

the temperature of main unit is higher/lower the setting high/low temperature, it will force the main 

and slave unit operate the setting temperature to be cool/heat mode with locked temperature at the 

same  time.  When  the  temperature  which  checked by  the  main  unit  is  lower/higher  the  setting 

high/low temperature 2°C, the main unit will recover to the previous operating state, and the slave 

unit will automatically off.
