The star with a face is sleep mode, each time you press it you will see a 1 then 2 then 3 up to 7 appear in the lower right corner of the screen. This means that the unit will operate for 1 or 2 or 3 hours then switch off. The house with key if pressed will give you the actual room temperature assuming the remote control is in the same room. It will return to setpoint temperature in a couple of seconds. The triangle with face is termed "Chaos mode" The unit will stay on a preset temperature probably 18c but the airflow will vary and the louver will go up and down irratically or randomly, as it tries to immitate a natural breeze. The fan only button will put the unit into fan mode (no compressor driven cooling), the fan icon with circle around is for fan speed which goes up each time it is pressed. Hope this helps.

The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye

please check the temperature sensor this will make the compressor for running and stopping and also check the compressor if its in warranty period please call the service technician to check these and replace if necessary.

1. Do not set the aircon too low temperature in overcast weather, this will cause ice ups and water dripping. Optimal comfort zone temperature is 24c.
2. You need to open the grill cover on the front of the aircon which unclips either end left and right with a finger pressure. You will find two filters which can slide out and should be cleaned. First tap them together to remove dust, then you can wash them with mild soap and cold water.
3. There is the third possibility that an insect has made a nest in the drainpipe. You should look on the outside of the building and locate a plastic drainpipe. You can either blow into this pipe with your mouth or get a blower. This will unblock any restriction in the drainpipe.
Goodluck and ratemeplease.
