Daikin heating & air conditioning symbols
Daikin: symbols on air conditioner remotes and indoor-unit displays, dehumidifiers, electric and oil-filled heaters, and boiler displays: operating modes, fan and airflow settings, timers, comfort functions and status or fault indicators.
AUTO modeHeating & air conditioningAUTO modeThe air conditioner picks COOL or HEAT by itself from the room and outdoor temperatures, and re-checks at regular intervals to hold the set temperature. Set temperature range in AUTO: 18–30 °C. Selected by pressing the Mode button until this icon shows on the remote's display.On ARC466A9
Airflow rate: AutoHeating & air conditioningAirflow rate: AutoShown when the Fan button is set to Auto: the unit chooses the airflow rate itself. Pressing the Fan button steps through Auto, indoor unit quiet, then five fixed levels from low to high. In DRY mode the airflow rate cannot be changed.On ARC466A9
COMFORT AIRFLOWHeating & air conditioningCOMFORT AIRFLOWDirects the air upward when cooling and downward when heating so it does not blow straight at people. Airflow rate is set to Auto, and choosing up and down swing cancels it. It cannot run together with POWERFUL; the last one selected wins. Selected with the Comfort/Sensor button.On ARC466A9
COOL modeHeating & air conditioningCOOL modeCools the room by moving its heat outdoors. Set temperature range: 18–32 °C; 26–28 °C is the suggested setting to save energy. Cooling performance can drop when it is very hot outside.On ARC466A9
DRY modeHeating & air conditioningDRY modeRemoves humidity from the room while keeping the temperature as steady as possible. The unit controls temperature and airflow itself, so neither the set temperature nor the fan speed can be changed in this mode. Intended for indoor humidity up to 80 %; outside its operating range a safety device may stop the unit.On ARC466A9
ECONOHeating & air conditioningECONOCaps the air conditioner's maximum power use so it is less likely to trip a circuit breaker when other high-power appliances run at the same time. Works in AUTO, COOL, DRY and HEAT, only while the unit is running, and cannot be combined with POWERFUL. If power use is already low it has no effect.On ARC466A9
FAN modeHeating & air conditioningFAN modeRuns only the indoor fan to circulate air, without cooling or heating. The set temperature cannot be changed in this mode.On ARC466A9
HEAT modeHeating & air conditioningHEAT modeHeats the room with the heat pump, taking heat from the outdoor air. Set temperature range: 10–30 °C (20–24 °C suggested). It takes a while before the room warms up, and heating capacity falls when it is cold outside. When frost builds up on the outdoor unit the system defrosts it, and no warm air comes out during that time; when the set temperature is reached heating stops but the indoor fan keeps running.On ARC466A9
INTELLIGENT EYEHeating & air conditioningINTELLIGENT EYEAn infrared sensor watches for people. The louvers steer the air towards areas where nobody is detected, and if no one is seen for 20 minutes the unit switches to energy saving: 2 °C lower in HEAT, 2 °C higher in COOL and DRY (1 °C above 30 °C room temperature), slightly less airflow in FAN. Can be combined with COMFORT AIRFLOW.On ARC466A9
Indoor unit quietHeating & air conditioningIndoor unit quietOne of the Fan button settings: the indoor fan runs at a weak airflow so the indoor unit is quieter. If the room does not reach the set temperature, choose a higher airflow setting.On ARC466A9
OUTDOOR UNIT QUIETHeating & air conditioningOUTDOOR UNIT QUIETLowers the noise of the outdoor unit by reducing its compressor frequency and fan speed, useful at night for neighbours. Available in COOL, HEAT and AUTO only, not with POWERFUL. The icon stays on the remote display even after the unit is switched off.On ARC466A9
POWERFULHeating & air conditioningPOWERFULGives maximum cooling or heating capacity for 20 minutes, then returns to the previous settings. In COOL and HEAT the airflow is fixed at maximum and temperature and airflow cannot be changed; in AUTO the airflow is also fixed at maximum; in DRY the set temperature drops by 2.5 °C and airflow rises slightly; in FAN the airflow is fixed at maximum. It only works while the unit is running and cannot be combined with ECONO, COMFORT AIRFLOW or OUTDOOR UNIT QUIET.On ARC466A9
Right and left swingHeating & air conditioningRight and left swingShown when the louvers (vertical blades) swing left and right. Combined with the up and down swing the flaps and louvers move in turn (3-D airflow), which mixes cool air near the floor and warm air near the ceiling. Press the button again to stop the louvers in the current position.On ARC466A9
Up and down swingHeating & air conditioningUp and down swingShown when the flaps (horizontal blades) swing up and down to spread the airflow. Press the swing button again when the flaps are where you want them to stop them there. Always move the flaps with the remote, never by hand.On ARC466A9
