Air conditioner LG what does CO mean

Deciphering codes of air conditioning errors of popular brands

Both household and industrial air conditioning systems, for the most part, have a function of self.diagnosis. This function can work in automatic or in a special one if there are problems with the equipment. As a rule, information with error codes can be observed on displays located on internal blocks of the split systems. Thanks to these data, malfunctions are precisely determined, due to which violations in the operation of the air conditioning system have occurred. To independently determine the causes of malfunctions in devices of different manufacturers, you can use the lists of codes of errors of various air conditioners provided below by brands.

In the air conditioning systems, the microprocessor, when some malfunction is detected, blocks the unit starting, after which it gives signals to flashing the LED, which report the error code.

If the system has discovered several problems, then first of all, the breakdown is induced, which has the smallest serial number. After that, there is an indication of malfunctions in an increase in the order. The table provided below indicates LG air conditioning errors and deciphers that each of them means.

You should know: the occurrence of similar errors can be provoked by unsatisfactory parameters of the electrical network, or a random failure that occurred in the electronics of the unit. Therefore, do not rush to contact the service immediately, but simply de.energize the device and check the electrical voltage. It is also necessary to make sure that the operation mode is selected correctly. After these checks, you can turn on the device. Most often, this method helps in solving this problem, and it no longer appears.

A set of fault designations found by the microprocessor depends on the model of the unit. There may be another indication for LG air conditioners. in the form of numbers and letters.

Designations of defects of the condenser unit:

Special abilities

They are not implemented in every model. However, many of them for verification are very interesting and useful.

• Comfort settings allow the inclusion of equipment for drawing the optimal temperature balance. The technique itself will produce the necessary adjustments and give out optimal results. Usually for heating this is an indicator of 20 degrees, and 25 degrees are used for cooling.
• It turns out to be cleaning the room from the dust coming with street air. Typically, a variety of filters are used here. rough cleaning (removes large particles of dust) and thin cleaning (which work even with floral pollen). There are also filters that remove the smell of smoke.
• 3D stream is used to deviate an air flow vertically. This will help the user not to catch a cold. And in some models, the device itself determines the location of the remote control (IFEEL function) and sends air masses in its direction.
• Ionization involves the saturation of microclimate ions with negative charges. This improves the user’s immunity and his well.being. According to some people, the sensations of a sea breeze are created.
• Low temperatures outside the window? So, it’s time to turn on the “defrost” of the external unit. The refrigerant will collect all the cold, which came with street air masses.
• Finally, self.diagnosis is one of the most useful functions. The device itself will automatically determine its own malfunction. this will help to quickly cope with the problem and prevent breakdown.

Additional modes and functions of the air conditioner

Modern models of climatic equipment, in addition to basic options, are equipped with other useful functions that can be useful during the operation of the device.

Air moisturizing and purification functions

Dry air in the room causes discomfort when breathing, which is especially unsafe for people suffering from asthma. A special function of moisturizing in split systems involves saturation of air with moisture to create a comfortable microclimate in the room.

Many models of split systems have additional filters in equipment for cleaning air indoors. The degree of cleaning depends on the quality and number of installed filters. Modern devices effectively clean the air of dust, pathogenic microorganisms, bacteria and unpleasant odors, including tobacco smoke.

Health conditioner mode

Health mode. indoor air ionization. When activating the regime, negatively charged ions are generated that purify the air from dangerous chemical compounds. They also have an antibacterial effect.

AUTO or automatic air conditioner mode

The automatic mode of split systems involves automatic adjustment of the air temperature in the room within the set range. In the process, the device will independently include the cooling/heating, ventilation and drainage mode to ensure a comfortable microclimate in the room.

I Feel function in the air conditioner: what is it

The I Feel mode is a smart function of climatic equipment that determines the comfortable air temperature for the user, based on its previous preferences.

After the launch of this mode, the microprocessor of the device sets the desired temperature parameter and remembers it, which further simplifies the adjustment of the temperature regime.

If the user wants to change the parameter selected by the program, he can go to the standard mode of air temperature adjustment and set the desired values.

Swing function. blind manual

Swing function is necessary to change the position of the air conditioner. This mode allows you to independently configure the direction of chilled air flows in the room. On the control panel, this function is marked by the inscription Swing or the image of wavy lines.

Timer

In almost all models of split systems there is an option “Timer”. The user can set the time to start and disconnect the device.

For example, you can set the time for turning on the air conditioner a couple of hours before the arrival of home and turning it off during the time when all households leave the house. That is, while the person in the house is in the house, a comfortable air temperature will be maintained, and in the absence of people in the room, the air conditioner will automatically turn off, according to the set time completion of the work.

LG air conditioning errors

If the air conditioning control system has discovered more than one error, first an indication is indicated with the smallest serial number, and then all the rest (by increasing the serial number of the error). LG air conditioning codes are given in the table. one.

It should be noted that such errors may occur if the parameters of the supply network (as well as other parameters. see. The instruction manual for a specific type of apparatus) do not satisfy the recommended values, as well as as a result of an accidental failure of the air conditioning control system. Therefore, before proceeding with the detection of a malfunction or contacting the LG authorized service center, it is necessary to de.energize the device, check the supply network, the correct choice of the operating modes, and then turn it on again. In some cases, an error may no longer occur.

Self.diagnosis system of air conditioning

For the convenience of users, manufacturers equip air conditioners with a large set of useful functions, one of which is a self.diagnosis system. This auxiliary tool timely identifies the slightest malfunctions in the operation of climatic equipment and informs of possible malfunctions and breakdowns, which, in turn, saves the owner from unnecessary expenses for the repair of technology.

The owner can eliminate some malfunctions independently, while others require the intervention of an experienced specialist from the service center. To determine the cause of the malfunction and the need to call the master will help error codes.

Where error codes are displayed (depending on the model of the air conditioner):

• On the display of the device.
• On the remote control.
• LEDs on the block. In normal mode, they burn with even light. If the technique has a failure, the LEDs flashed with small interruptions.

To determine the breakdown of the error code, the owner needs to study the decoding of characters.

In 1947, the Korean company Lak Chemical Co was created, which subsequently grew into the world concern LG. The concern includes 10 companies. In 1958, the company completely diversified production and began to engage in electronic devices. In 1975, LG opened the first representative office in the United States, and a few years later a production enterprise.At the moment, about 19 representative offices and 56 branches of the company are located around the world. For the first time in Russia, the company appeared before 1995 and was known to our consumer called Goldstar.

LG company is engaged in the production of various household and industrial equipment, all kinds of multimedia devices, electronics, computer equipment and mobile devices. The company’s assortment is widely provided: washing machines, TVs, CDs and DVDs. players, refrigerators, computers and related devices, household conditioners and many. etc.

LG Korean air conditioners rightfully occupy a leading position around the world, complying with the latest technological developments and the requirements of a modern buyer. The company produces many models from window air conditioners to modern split systems in a different price range.

LG window air conditioners are a monoblock type of air conditioning. This means that all parts of the circuit are collected in one case. Window air conditioners are less and less used in household use because they are installed exclusively in the window opening and have an increased noise during operation. Nevertheless, there are advantages in such models, for example, the low price and the fact that during the work of the window air conditioner, part of fresh air enters the room due to the features of the device. In the model range of the company, several options for such air conditioners are proposed, some models include a remote control for the air conditioner, the work of the rest is regulated using the control panel. One of the representatives of window air conditioners is the W05LC device designed to cool 15 m² of area and equipped with a function of regulating the direction of air flow.

Wall conditioners include split systems: G07LHK, LG G09LHK, which, like all wall-mounted LG air conditioners, are equipped with the Jet Cool turbochering function, which allows you to quickly reach the necessary room temperature. S07LHQ, S09LHQ, S12LHQ air conditioners are equipped with NEO Plasma, anti.allergenic filter, triple filter and antibacterial coating. The difference in these models lies in the area of ​​the conditioned space. Neo Plasma system is a unique development of a company that is based on 12 level air purification by bio-enzy filters. Due to the high sterilization ability of the system, all bacteria, dust particles and spores of fungi are destroyed.

Multi split systems differ from other air conditioners by the presence of more internal blocks, which is very convenient if it is necessary to save space on the facade of the building. In the case when the external block of such air conditioners fails, replacement and internal blocks are necessary.

The Art Cool series is a bright representative of wall split systems. Art Cool is inverter air conditioners. DC Inverter technology in such air conditioners can significantly save electricity, at the same time cooling or heating the air as quickly as possible. The Art Cool series has an exquisite design, thanks to the special grace of the appearance and the decorative front panel, which involves a change of image. ART COOL is equipped with an auto.cleaning and distribution of air flow in three directions, additional protection of the heat exchanger involves the Gold FIN anti.corrosion coating, which is golden spraying on the aluminum surface. Split systems S09AF and S12AF also relate to inverter air conditioners. An increase in the cavity of pipelines and a decrease in the external unit in these models can significantly simplify their installation.

Thanks to the development of a centrifugal duct and fan, LG channel air conditioners have a super.harsh noise level. Due to the ability to air conditioning, channel air conditioners are advisable to use for cottages, restaurants, hotels, offices, etc. D. The difference between such air conditioners is that the internal unit or several blocks are mounted behind a bearing ceiling or in specially designed niches, which allows you to maintain the common interior of the room without changes.

Cassette air conditioners are used to recreate the microclimate and when it is necessary to cover various zones of the room, which is not achievable using wall air conditioners. Cassette air conditioners not only qualitatively cope with maintaining the optimum air temperature, but also do not at all violate the design of the room, thanks to the installation in the inter.first space.

Ceiling air conditioners and floor air conditioners are most often installed in premises for various purposes, where installation of wall splitting systems is impossible.

Mobile air conditioners allow air conditioning the room without installing the system. The cooling of the room is achieved due to the release of hot air with a flexible duct to the street. Mobile air conditioners are easy to move due to lightweight and built.in wheels. Each model is equipped with a special container for condensate collection, the accumulation of which leads to a shutdown of the device.

How to decipher the air conditioning marking

On the front panel of the internal block, the name of the model and marking from the set of numbers and letters are also indicated. Consider how these values ​​decrypted.

Deciphering marking on air conditioners:

• GWH or SRK. household air conditioning, GU or SRR. semi.industrial type of equipment.
• The next two numbers are 07, 09, 12, 13, 14, 18, 24, 27 or 30-the power of the split system measured in BTA/hour. “07” is power 2.1 watt, “09”. 2.6 watts, “12”. 3.5 watts, “18”. 5.2 watts and t. D.
• The following are the letter and digital values ​​that determine the series and model of the device.
• The last set of numbers is 1/4 3/8, 1/4 1/2 or ¼, 5/8 determines the diameter of the copper pipe indicated in the inch.

In addition to digital and letter values, there may be additional stickers and flyers on the air conditioning case, displaying the list of additional functions of the device.
