Frequently Asked Questions - PQRCHCA0Q LG

How to install the wired remote control?

Attach the installation panel to the wall using the supplied screws. Connect the connection cable between the remote control and the indoor unit (max length 10 m, use an extension if necessary). Insert the remote control into the panel by clipping the top then bottom. To remove, insert a screwdriver into the separation hole and turn clockwise.

How to access the installation configuration mode?

Press and hold the Temperature + and Ambient temperature buttons simultaneously for 5 seconds. The screen then displays the function code (e.g., 01 for operation test).

How to configure group control with multiple indoor units?

Connect the indoor units in parallel to a single remote control. Set the slave units via the PCB switch (for duct models) or via the wireless remote control. On the wired remote control, set it as master (code 07, value 01). Refer to the manual for limitations.

How to change the display from Celsius to Fahrenheit?

In configuration mode (Temperature+ and Ambient buttons for 3 seconds), select function code 12, then set to 00 (Celsius) or 01 (Fahrenheit) using the temperature buttons. Confirm with the On/Off button.

What to do if the remote control does not communicate with the indoor unit?

Check the wiring: correct connection of wires (3 conductors?). Make sure the remote control is properly installed in its panel. Restart the indoor unit. If the problem persists, test in operation test mode (code 01) or contact an installer.

How to activate parental control?

Press and hold the On/Off and Fan speed buttons simultaneously for 3 seconds. The screen displays 'CP'. Then, only authorized buttons will work; to deactivate, repeat the same operation.

What does the error code or PSE (Electronic Static Pressure) parameter mean?

PSE adjusts the fan strength for each level. It is set in installation mode (code 03). Value from 0 to 255. Incorrect configuration may cause malfunction; set it only if necessary and by a technician.

How to clean the remote control?

Use a soft dry cloth. Never use solvents, strong detergents, or water. Avoid scratching the screen.

Can I use this remote control with any LG air conditioner?

No, this model is only compatible with specific LG indoor units (models PQRCHCAOQ and PQRCHCAOQW). Check compatibility in your air conditioner's manual.

How to replace the connection cable if damaged?

Purchase a replacement LG cable of the same length (max 10 m). Disconnect power, remove the remote control from the panel, disconnect the old cable and connect the new one to the terminals of both devices. Reassemble. Call a professional if necessary.

TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.
