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 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 Condition

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.

DRY Mode

SLEEP Mode

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. It will cause poor performance, increased running 

costs and reduced product life. 

● 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.

ECO mode can be activated at cooling mode for energy saving. When selected, 

the unit will automatically regular the fan speed and compressor rotation. It 

provides you the same comfort with minimum power consumption in 8 hours 

running time.

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 automatically. For some units, it keeps running with this 

new temperature all the time until you adjust it.

This operation saves energy and improves night time comfort by synchronising with

 the body’s metabolism.
