Usage Features
- Remote Control: The primary interface for controlling the air conditioner. It features buttons for various modes, fan speed, temperature adjustment, timer settings, and special functions like "I FEEL" and "T-ON/T-OFF".
- Auxiliary Button: A button on the indoor unit allows turning the air conditioner on or off, especially if the remote controller is lost or damaged. When pressed, the air conditioner operates under auto mode.
- Operation Modes:
- FAN AUTO: Automatically adjusts fan speed.
- TURBO: Provides rapid cooling or heating.
- AUTO mode: Automatically selects operation mode based on room temperature.
- COOL mode: For cooling.
- DRY mode: For dehumidification.
- FAN mode: Circulates air without cooling or heating.
- HEAT mode: For heating.
- SLEEP mode: Adjusts temperature for comfortable sleep and energy saving.
- 8°C heating function: Maintains a minimum temperature of 8°C to prevent freezing.
- Timer Function: Allows setting the unit to turn on or off at specific times. The "T-ON/T-OFF" button is used for this.
- "I FEEL" Function: The remote controller measures the temperature at its location and sends this information to the indoor unit, allowing the air conditioner to adjust the temperature for optimal comfort around the user.
- Swing Function: Controls the horizontal and vertical airflow direction.
- Child Lock Function: Prevents accidental changes to settings.
- Auto Clean Function: Cleans the indoor unit evaporator to prevent mold and odors.
- Power Limiting Operation: Reduces power consumption.
- Health Mode: Activates specific functions for improved air quality.
- Scavenging Function: Likely related to air purification or ventilation.
- Wi-Fi Function: Allows for remote control and monitoring via a Wi-Fi network.
- Temperature Display: The indoor unit displays the set temperature.
Maintenance Features
- Filter Cleaning: The air filter should be cleaned every three months, or more frequently depending on usage and environmental conditions. It can be removed for cleaning.
- Indoor Unit Surface Cleaning: The indoor unit surface should be cleaned with a soft dry cloth or wet cloth to wipe it. Do not use volatile liquid cleaners.
- Outdoor Unit Cleaning: The outdoor unit should be cleaned regularly to ensure proper heat dissipation.
- Pre-season Check: Before the use season, check air inlets and outlets, switch and socket, filter, mounting bracket, and drainage pipe.
- Post-season Check: After the use season, check power supply, filter, mounting bracket, and drainage pipe.
