Function Description
The ComfortStar Split Type Air Conditioner is designed to provide cooling, heating (for heat pump models), dehumidification, and fan-only ventilation for domestic environments. It consists of an indoor unit and an outdoor unit connected by refrigerant piping and electrical wiring.
Operating Modes:
- Cooling Mode: Cools the room and reduces air humidity.
- Heating Mode: Heats the room (for heat pump models). During heating, the appliance may automatically activate a defrost cycle to clean frost from the condenser and recover heat exchange function. This typically lasts 2-10 minutes, during which the indoor unit fan stops. A forced defrosting option is available for North American markets by pressing the ECO button 10 times within 8 seconds in heating mode.
- Dry Mode: Reduces air humidity for increased comfort.
- Fan Only Mode: Provides air ventilation without cooling or heating.
- Auto Mode: Automatically selects the operating mode based on the room temperature.
Special Functions:
- Timer ON/OFF: Allows automatic switching on or off of the appliance at a set time.
- SWING Function: Controls the movement of horizontal flaps (up/down) and vertical deflectors (left/right) to adjust airflow direction.
- TURBO Function: Activates quick cooling or heating with the highest fan speed for strong airflow.
- MUTE Function: Operates the indoor unit at the lowest fan speed for a quiet experience. Not available in dry mode.
- ECO Function: Automatically sets the operation to save energy, available in both cooling and heating modes.
- SLEEP Function: Activates a pre-setting automatic operating program. After 10 hours, the air conditioner returns to the previously set mode.
- DISPLAY Function: Switches the LED display on the indoor unit panel ON or OFF.
- I FEEL Function (Optional): Enables the remote control to measure the temperature at its current location and send this signal to the air conditioner to optimize the temperature around the user. Automatically deactivates after 2 hours.
- GEN Function (Optional): A specific function that can be activated and deactivated, with different operating gears (L3, L2, L1, OF).
- SELF-CLEAN Function (Optional): Helps carry away accumulated dirt and bacteria from the indoor evaporator. Runs for about 30 minutes and then returns to the pre-setting mode. Available for some heating pump inverter appliances.
- Gentle Wind Function (Optional): Closes vertical flaps to provide a comfortable gentle wind feeling.
- Health Function (Optional): Initiates Ionizer/Plasma/Bipolar Ionizer/UVC Lights (depending on models) for air purification.
- 8°C Heating Function (Optional): Automatically starts heating mode when the room temperature is below 8°C (46°F) and returns to standby when it reaches 9°C (48°F). Cancels automatically if the room temperature is higher than 18°C (64°F).
- I SET Function (Optional): Allows users to memory their favorite temperature, mode, and fan speed settings for quick recall with one button press.
- Child-Lock Function: Locks the remote control buttons to prevent accidental changes.
