- APPLY Button: Confirms settings made on the remote controller.
- °F/°C Button: Toggles between Fahrenheit and Celsius temperature displays.
- Wi-Fi Function: Enables remote control of the air conditioner via a smartphone app ("hOn" APP). Users can register, connect the unit, and manage operations through the app.
- ECOPILOT Operation (Human Sensing Function): This advanced feature detects human presence and movement. In "Follow" mode, it directs airflow towards occupants. In "Avoid" mode, it steers airflow away from occupants. It can also enter a power-saving mode if no presence is detected for an extended period and adjust frequency and fan speed based on movement intensity.
- Steri Clean Operation: A self-cleaning function that freezes the evaporator to remove dirt, followed by a 56°C high-temperature sterilization phase to kill bacteria and viruses. It concludes with rapid evaporator cooling to enhance sterilization performance. This function is typically accessed via the hOn APP.
- UV Sterilization Function: Utilizes a UV-C lamp to remove harmful microorganisms from the air, contributing to healthier indoor air quality.
Usage Features
The manual emphasizes several key aspects for optimal use:
- Remote Controller Usage: The remote controller has a signal transmission range of up to 7 meters without obstacles. It's important to replace batteries when the display becomes dim or unclear. If the remote controller malfunctions, removing and reinserting batteries can reset it.
- Clock Setting: Users can set the current time on the remote controller, which is crucial for timed operations.
- QUIET Operation: Ideal for periods requiring silence, such as rest or reading.
- COOL, HEAT, and DRY Operation: Standard modes for temperature and humidity control. In DRY mode, the unit runs intermittently at low speed if the room temperature is close to the set temperature. The remote controller memorizes the last operation status for convenience.
- FAN Operation: Allows users to select various fan speeds (AUTO, low, medium, high) to control airflow intensity.
- SWING Operation: Provides control over both vertical and horizontal airflow directions, allowing users to customize air distribution.
- TIMER Operation: Enables scheduling the air conditioner to turn on or off automatically at specified times, useful for pre-cooling/heating or energy saving.
- Comfortable SLEEP Mode: Automatically adjusts temperature settings during sleep to maintain comfort and save energy. The temperature changes gradually over several hours in both cooling/dry and heating modes.
- Power Failure Resume Function: The unit automatically restarts with previous settings after a power outage, with a 3-minute delay for compressor protection.
- SMART Operation: Simplifies operation by automatically selecting the appropriate mode (cooling, heating, dehumidifying, or blowing) based on indoor conditions.
- ON/OFF and Test Operation: In cases of a defective or lost remote controller, the unit can be operated via an emergency switch. Test operation is available for specific conditions, such as when the room temperature is below 16°C.
- Wi-Fi Connectivity: The "hOn" APP allows for advanced control and monitoring of the air conditioner from a smartphone, including activating the Steri Clean function.
Maintenance Features
Regular maintenance is crucial for the air conditioner's performance and longevity:
- Proper Room Temperature Setting: Maintaining an appropriate temperature helps in efficient operation.
- Avoiding Obstructions: Ensure that the air inlet and outlet are not blocked to allow for proper airflow.
- Effective Timer Use: Utilizing the timer function contributes to energy saving.
- Closing Doors and Windows: During operation, keeping doors and windows closed prevents energy loss.
- UV Sterilization Function: It is recommended to turn on the UV sterilization function for 1-2 hours daily. Users are warned not to look directly at or touch the UV lamp when it is on and to turn it off before opening the panel.
- Remote Controller Care: Clean the remote controller with a dry cloth; avoid using water, glass cleaner, or chemical cloths.
- Indoor Body Cleaning: Wipe the indoor unit with a soft, dry cloth. For stubborn stains, use a neutral detergent diluted with water, wringing the cloth thoroughly before wiping. Avoid hot water or harsh chemicals.
- Air Filter Cleaning:
- Partially raise the panel by pressing the "SMART" button for 5 seconds.
- Open the panel manually and support it.
- Remove the air filter.
- Clean the filter (recommended every two weeks).
- Fit the filter back.
- Remove the holder and close the panel by long-pressing the "SMART" button.
- Air Purifying Filter Replacement:
- Open the inlet grille by pressing the "SMART" button for 5 seconds.
- Detach the standard air filter by sliding the knob upward.
- Remove the old air purifying filter.
- Insert new air purifying filter appliances into the right and left filter frames, ensuring the correct orientation (white side of photocatalyst filter facing outside, black side facing the unit; green side of bacteria-killing filter facing outside, white side facing the unit).
- Attach the standard air filter.
- Close the inlet grille by long-pressing the "SMART" button.
- Photocatalyst Air Purifying Filter Solarization: This filter should be solarized every 6 months for optimal performance.
- Bacteria-Killing Medium Air Purifying Filter: This filter has a long lifespan but needs frequent dust removal using a vacuum cleaner or by lightly flapping it. Avoid prolonged direct sunlight when not in use to maintain its sterilization ability.
