2.2 Manual Operation

Manual operation is available to control the unit when your remote is unavailable.

ACCESS

Open the front panel by carefully 
lifting both ends at the same time.
Once lifted sufficiently, a click is heard 
and it becomes self-supporting.

OPERATE

Press the manual button repeatedly to change modes as follows;
a Once = AUTO mode [heat, cool or fan 24°C and auto fan speed].
b Twice=COOLING mode [ switches to AUTO mode after 30 minutes (mainly used for 
testing purpose)].
c Three times = OFF.

COMPLETE

Close the panel by firmly tugging downwards on both ends until it returns to its original 
position.

RESTORE

Using the remote controller will return the unit to normal operation.

2.1 Operating temperature

2.3 How It Works!

● In this setting the system will automatically change modes and fan speed to the set 

temperature.

● [In spring and autumn, closer temperature control may require 

COOL/HEAT mode 

changes.]

In this mode, priority is given to dehumidifying the air. Low fan speed and compressor 
cycling is used to achieve this and regulate room temperature.

When selected, the set temperature will increase
(cooling) or decrease (heating) by 1°C
per hour for the first 2 hours. Thereafter it 
keeps this new temperature for 5 hours
before switching off.

This operation saves energy and improves night time comfort by synchronising with the 
body’s metabolism.

Hints For Economical Operation

● Adjust the temperature to achieve moderate comfort levels. 
● Excessively low or high temperatures waste energy.
● Improve performance by keeping windows and doors closed.
● Limit energy usage [run time] by using the TIMER function.

● Do not block air inlets or outlets. Poor performance, increased running costs and

   reduced product life will result. 

● Inspect the air filters periodically, and clean them when needed.

1. Optimum performance will be achieved within these operating temperatures. 
2. When the unit operates above or below these conditions for a long time, system diagnostics may detect a malfunction 
and the unit will not operate properly.
3. Room relative humidity - less than 80%. If the air conditioner operates outside this range, the surface of the air conditioner 
may attract condensation. Please set the air flow louver to its maximum angle and set HIGH fan mode.
