Understanding the Display 

 

The Clock Area shows the Date, Time and Day of the week

.  

 
Pressing and holding the CLOCK button with the unit off allows these parameters to be 
scrolled through and changed using the TIME UP & DOWN buttons to increase and de-
crease the setting and the CLOCK button to scroll to the next function. After setting the 
date, time and day of the week press RESET to leave the programming mode. 

 
 

The Mode Area shows which mode the unit is currently set to work in. 
This is set using the MODE button on the controller. 

Automatic mode allows the unit to automatically select heating or cooling in 
order to maintain the desired room temperature. For your comfort we rec-
ommend setting the temperature to between 22 & 24C in automatic mode. 

Cooling Mode allows cooling to be used to prevent the room temperature 
exceeding the set temperature during summertime use. For your comfort we 
recommend not setting the desired temperature below 22C in cooling mode. 

Dry or Dehumidification Mode uses the units cooling function to reduce the 
humidity in the room. It is designed to make the room comfortable with 
reduced energy consumption compared with cooling mode.  

Fan Only Mode uses the indoor fan to generate air movement within the 
room but without cooling or heating the room. It is often used to prevent a 
room getting ‘stuffy’ 

Heating Mode allows heating to be used to prevent the room temperature 
dropping below the set temperature during winter use. For your comfort we 
recommend not setting the temperature above 24C in heating mode.

What do you want the unit to do? 

Pressing the mode button scrolls between automatic, cooling, dry, fan 
only and  heating modes. Choose the mode most appropriate to your 
needs. 

• 

Automatic will engage whichever mode is necessary to maintain 
the set temperature 

• 

Cooling will cool the room down to the set temperature 

• 

Dry will remove moisture and cool the room down. 

• 

Fan  Only  will  give  air  movement  in  the  room  without  heating 
and cooling 

• 

Heating will heat the room up to the set temperature 

 

Note—the unit will only be able to reach the set temperature if it is powerful enough to 
do so. Your air conditioner is not designed to cool a room down to 20C or less for long 
periods or heat it up to 25C or more for long periods and, depending upon the heating 
or cooling requirements of your room may be unable to do so at all.

 

 

Setting the Set Temperature 

Use TEMPERATURE UP & DOWN to increase or decrease the set tem-
perature to the required level. We recommend between 22C & 24C for 
an optimum comfort level. 
 

Setting the Auto Swing Louver 

Press SWING while the unit is operating to start or stop this function. 
 

Setting the Indoor Fan Speed 

Press FAN while the unit is running to increase or decrease the indoor 
fan  speed  or  choose  automatic  fan  speed  to  let  the  unit  choose  the 
most appropriate. 
 

Setting the Keyboard Lock 

Press  and  hold  RESET  for  six  seconds  to  turn  the  keyboard  lock  on 
and off.
