Remote Controller Overview

The remote controller transmits signals to the air conditioning system.

POWER: Starts or stops the appliance. The appliance will start when energized or stop when in operation.

MODE: Press to select the operation mode.

TEMP. Δ / ▽: Used to adjust the room temperature and the timer, also real time.

FAN SPEED: Used to select fan speed in sequence: Auto, Higher, High, Medium, Low, Lower.

SWING (invalid for some models): Used to stop or start vertical adjustment of the louver for airflow direction control.

IFEEL: Used to set IFEEL mode operation. The remote controller's built-in temperature sensor senses the surrounding temperature and transmits the signal to the unit to adjust the temperature for maximum comfort.

CLOCK: Used to set the current time.

CLEAN mode (invalid for some models): When the air conditioner is in standby and in Cooling or Dry mode, press the QUIET button for 5 seconds to start Clean mode. A "Clean" indicator will display on the LCD.

Storage and Tips

The remote controller can be stored mounted on a wall with a holder (optional part).

Operating the Air Conditioner

Aim the remote controller at the signal receptor of the indoor unit. The remote controller operates at a distance of up to 7 meters.

CAUTIONS:

• Keep the signal receiver away from direct sunlight, strong lights, or heat sources.
• Avoid placing the receiver near flat panel televisions or other electrical appliances that may interfere with remote signals.
• Ensure curtains, doors, or other materials do not block the signals between the remote controller and the indoor unit. If transmission is poor, reposition the materials or consult your dealer.

Operation Instructions

Selecting Mode

Press the MODE button repeatedly. The operation modes change in sequence: COOLING, DRY, FAN ONLY, HEATING.

Note: Heating mode is not available for cooling-only air conditioners.

FAN Mode

Press the FAN SPEED button repeatedly. The fan speed changes in sequence: Auto, Higher, High, Medium, Low, Lower.

Note: In "FAN ONLY" mode, "AUTO" is not available. In "DRY" mode, fan speed is automatically set to "AUTO", and the FAN button is ineffective.

Setting Temperature

Press the TEMP. Δ button to raise the temperature setting by 1°F.

Press the TEMP. ▽ button to lower the temperature setting by 1°F.

Note: Press and hold the TEMP. Δ and TEMP. ▽ buttons together for 3 seconds to switch between °C and °F display.

Note: In "Dry" mode, temperature can be adjusted by 7°F up or down for comfort.

Turning On

Press the POWER button. The RUN indicator on the indoor unit will light up.

Note: Changing modes during operation may sometimes result in a delayed response. Wait 3 minutes. During heating, airflow is not discharged immediately; it starts after 2-5 minutes when the indoor heat exchanger warms up. Wait 3 minutes before restarting the appliance.

Airflow Direction Control

Vertical Airflow

Vertical airflow is automatically adjusted based on the operation mode. In COOLING and DRY modes, airflow is horizontal. In HEATING and FAN ONLY modes, airflow is downward.

You can adjust airflow direction using the SWING button.

2. Press and hold the SWING button for 5 seconds: The vertical adjustment louver swings up and down at a smaller angle.
3. Press the SWING button again: The louvers adjust to a suitable angle.

Note: Do not manually adjust the vertical louvers, as this may cause malfunction. If this occurs, turn off the unit, cut off power, then restore power.

Note: Avoid tilting the vertical adjustment louver downward for extended periods in COOLING or DRY mode to prevent condensation dripping.

Horizontal Airflow

You can adjust horizontal airflow direction using the SWING button.

1. Press the SWING button once: The horizontal adjustment louver swings left and right automatically.
2. Press the SWING button again: The louvers adjust to a suitable angle.
