Preparations Before You Begin Make sure the unit is plugged into a separate power outlet and grounded. Install batteries in the remote control. Set the time. Check that foreign objects do not obstruct the air flow around the outdoor and indoor units. After installing the batteries in the remote control, you need to set the current time. To do this, press the RESET button, then specify the time and press the ON / OFF button. Then you need to press the 2F button and make sure that a similar inscription is lit on the screen. Further, by pressing the button for setting the time, we set the current time. Then press the TIMER SET / CANCEL button.

Selecting operating modes Pressing the power button on the remote control, turn on the air conditioner. Then, by pressing the operating mode selection button, you can select the operating mode you need now. By successively pressing it you will select the following modes (Cooling-Auto-selection-Drying-Heating). By selecting the desired mode, you can set the required temperature. The choice for the heating mode is possible in the range of 16-30, for cooling 18-30 degrees. After that, you can set the desired fan operating mode from several: CHAOS (a feeling of a light breeze is created) and four constant modes from weak to maximum power. Working in the dehumidification (dehydration) mode, the LG air conditioner reduces the level of humidity. The desired temperature level cannot be set as the device selects it by itself, taking into account the current selection. In any case, the air conditioner works in such a way as to reduce the humidity to a minimum affect the temperature. Unlike the Heating and Cooling modes, where the air conditioner only cools or heats, when you select the Auto select mode, you can specify the desired temperature range and when the temperature drops, the air conditioner will turn on the Heating mode, and when the temperature rises, on the contrary, cool the air in the room.

Additional modes and settings Fast heating / cooling mode. When the room temperature is too high or vice versa, it is recommended to first turn on the air conditioner at maximum power. After turning on it for 30 minutes (for cooling and 60 works with maximum heat transfer and ventilation. The automatic restart function. activates the operation of the air conditioner in the same mode in which it worked before the emergency power outage. For maximum air purification, there is a Plasma filter. started in any operating mode of the air conditioner by pressing the Plasma button on the remote control. “Self-cleaning” function starts the process of removing moisture from the internal cavities of the air conditioner, it is necessary after operation in cooling and dehumidification modes. operation, during which it is quieter and consumes less energy. Forced mode. if there is no remote control, you can turn on the air conditioner by pressing the button located on the indoor unit. By successively pressing it, you can turn on the cooling mode and turn off the air conditioner. Start the timer. time for remote control. By pressing on the remote control the start button of the second function (2F) and turn on the timer by pressing ON / OFF TIMER. Set the timer operation time using the time setting buttons. Do not forget that while you operate the air conditioner using the remote control, the command reception window and the remote control must be within sight. To disable the timer: check that the 2F button is inactive and press the TIMER CANCEL button. Then the timer image on the air conditioner and the display should go out.

TIPS: Do not overcool the room. This is harmful to health and unnecessarily increases energy consumption. Close curtains or blinds if the air conditioner is running. Do not expose the air conditioner to sunlight. Control the direction of the vertical flap so that the air temperature in the room is evenly distributed. Keep windows and doors tightly closed. Otherwise, cold air will leave the room. Clean the air filter regularly. A clogged filter reduces air movement and increases energy consumption. Remember to ventilate the room periodically. During the operation of the air conditioner, the air is not renewed as during ventilation, therefore it is necessary to monitor this additionally. To quickly cool the room at the start of operation, use a mode with an increased fan speed.

Cleaning Your Air Conditioner Choose a stable base to stand on. Remember to unplug the power plug before cleaning. Do not use water hotter than 40 degrees, gasoline, abrasive detergents. this can damage the appearance of the plastic. There are air filters behind the front panel. They should be checked and, if necessary, cleaned once a week. To remove dirt, you can use a vacuum cleaner, in cases where it is difficult to remove, you can wash the filter in warm water with the addition of liquid detergent. After washing, the filters must be dried in the shade (not in the sun). PLASMA filters must be checked at least once every three months. Cleaning can be done with a vacuum cleaner or washed with water. They also cannot be dried in the sun. Do not touch this filter for the first 10 seconds after turning off the air conditioner. Deodorizing filters must be removed, dried in the sun for 2 hours and replaced. Periodically inspect the outdoor unit of the air conditioner and, if contamination appears, remove it, for which you can call an employee of the relevant company. If it seems to you that there is a malfunction The air conditioner does not work. Check if it is connected to the power supply, if the circuit breaker has blown. It is also possible that there is no power in the network or the voltage is too high (in the second case, the protection of the air conditioner will work) The air conditioner does not cool properly. Check that there are no obstructions in the air flow around the outdoor and indoor units. The air filter must be clean. If the temperature is too high, the air conditioner becomes less efficient. Also check that the windows and doors in the room are closed. The temperature may not be set correctly. There may be a heat source in the room.

ALWAYS contact the service center if: there is a burning smell, loud noise in operation. Unplug the device and disconnect the plug from the socket immediately; the power cord or plug is hot and can be seen to be damaged; when the self-test is started, a malfunction code appears; water leaks from the indoor unit; circuit breaker malfunctions are detected.

If the air conditioner will not be used for a long time At the end of the season, the air conditioner must be prepared for shutdown. For what: clean the filters; turn on the warm-up mode for 1-2 hours to completely dry the indoor unit from the inside; turn off the air conditioner using the remote control; remove the batteries from the remote control; disconnect the plug from the power supply.

Before switching on after a long period of inactivity. Check that there are no obstacles to air movement near the outdoor and indoor units; install batteries in the remote control; set the time; connect the plug to the mains. Place of installation and electrical work Installation of the air conditioner must be carried out by certified specialists. Make sure that there will be no obstacles to air movement in the place of the intended installation, the noise of the outdoor unit will not interfere with those living nearby and it is possible to drain condensate from the outdoor unit.

Safety Precautions Use a mains plug and a grounded socket. Do not plug the air conditioner into an inferior outlet. Do not use an extension cord. plug directly into a wall outlet. Do not use a damaged plug or power cord. The power cord and plug must be handled with dry hands. Do not stand on your own or place heavy or hard objects on the power cord. It is forbidden to disassemble, repair, modify the device yourself. For any repair work, you need to invite a specialist. Make sure the mounting posts are intact and intact. The outdoor unit must be securely fixed to prevent it from falling. Do not place objects, especially those with water (for example, a vase of water) on the indoor and outdoor units. Do not insert your fingers or any other objects into the technological openings of the air conditioner. The fan runs at high speed, which could cause injury. If the air conditioner stops cooling or heating, it may indicate refrigerant leakage. In this case, it is necessary to call the repair specialists. Do not stand in the path of the cold air stream, it can damage your health.

Indoor and outdoor units

Decorative panel of the indoor unit. 2. This product discharges air on the sides. 3. Air is drawn to the heat exchanger from above. 4. At the outdoor unit, the intake is carried out on the back and side surfaces. 5. Air outlet, after contact with the heat exchanger in front.

Preparation before you start Remember that this model is plugged into a heavy-duty socket and consumes more power than a conventional appliance. Therefore, it must not be connected to extension cords, outlets of insufficient rating. As with most remotes, the requirements for batteries are the same. they must be of the same type, not rechargeable, correctly installed. Selecting operating modes After turning on the device, which is already connected to the network, you can select the mode you are interested in using the remote control. If you wish, you can fully automate the operation of the device by turning on the automatic mode. It is enough to specify the upper and lower temperature limits and you can forget about other actions. The device will automatically turn on the cooling when the temperature rises and vice versa. If you want to select a separate mode, it is easy to do. cooling mode is enough in summer, heating mode in cold weather. Dehumidification mode can be used separately. In this case, the device works in such a way as to reduce humidity, but at the same time not affect the temperature. When the ventilation mode is selected, the ventilation of the room air is simply maintained.

Additional modes and settings The “Neoplasma” filter perfectly removes odors from the air, along with other substances. Therefore, the “fan” mode is excellent for cleaning indoor air. Using the timer, you can set the time when the device turns on and off by itself. The self-diagnosis mode is convenient in that you can find out about the state of the device without resorting to third-party help. There is a self-cleaning function to combat the appearance of mold and bacteria. The device independently dries the cavities of the indoor unit. This prevents microorganisms from multiplying. For work at night there is a “sleep” mode. Thanks to the inverter type of operation, the device is very quiet. And in this mode it is even quieter. Helpful Hints If you plan to cool the room, then you need to not overdo it. excess cold will not be good for your health and you will waste a lot of energy. Do not forget to check the condition of windows and doors. if cold air leaves the room, then the work becomes much more difficult. At the beginning of work, it is worth applying an enhanced fan mode in order to cool the room faster. We must not forget about airing the room. Oxygen starvation can harm your health. Cleaning the air conditioner All actions must be performed with the air conditioner disconnected from the mains. Disconnect the plug with dry hands. All washed components must be dried in the shade. Do not use thinner, gasoline, abrasives, hot water, otherwise you will ruin the appearance of the plastic. If it seemed to you that there is a malfunction If the device does not work, check. it could have been turned off by the timer. Or it is simply not connected to the network. If the air conditioner does not cool well, then you need to check a number of points. It must be set to the correct mode and sufficient power. It is possible that the windows and doors in the room are open. If there are a lot of people in the room or a heating device is working, the air conditioner will work worse. The system that protects the device from frequent restarts will block the ability to turn on the air conditioner for 3 minutes immediately after it is turned off. If fog (white smoke) comes out of the air conditioner, remember that cold air, when it comes into contact with humid air, causes condensation. Also, remember that cold parts of the air conditioner will cause condensation to occur. therefore, water may flow from the air conditioner. When the dwelling is warmed up, the outdoor unit cools down and may freeze up. Therefore, the appliance must be stopped periodically to thaw ice, which can damage the appliance. In case of any problems with the remote control, first of all, check if the batteries are in order, if they are installed correctly, if the button on the remote control is jammed. The crackling sound may well accompany the device during heating. The sound of splashing, dripping may occur due to the movement of condensate, refrigerant. If there is a smell from the indoor unit, it may be time to clean it. Also, the smell may belong to a blooming wall, wallpaper, carpet.

When the air conditioner is taken out of operation for a long time Turn on the self-cleaning mode. Then turn off the device and do not forget to remove the plug from the socket and the batteries from the remote control. Before switching on after idle time, you need to check that both units are not clogged with foreign objects. Connect the device to the mains. Ground. Then install the proper batteries in the remote control and use the air conditioner. Selecting the installation site Do not install the air conditioner in places where there may be engine oil, flammable substances, hydrogen sulfide in the air. The outdoor unit makes noise during operation and may disturb people. In addition, when choosing a place for the air conditioner, it is necessary to provide for where you will remove condensate.

Precautions Please note that the appliance must be connected to an outlet of sufficient power, otherwise there is a risk of fire or melting. It is unacceptable to use extension cords. Connect and disconnect the device with dry hands. Never place heavy, hot, or other objects on the power cord. It is not allowed to place objects (especially with water) on both air conditioner units. Condensation may drip from the appliance. do not place furniture or other appliances under it. Do not overload the device. first disconnect from the remote control, and then remove the plug from the socket. Never stick your fingers into the air conditioner, it is dangerous. Do not expose yourself or others to prolonged, direct exposure to cold air. The complete cessation of heating and cooling may be due to a refrigerant leak. A burning smell or strange sounds during operation should alert you. unplug the device from the mains. Call specialists to assess the situation.

How to turn on the air conditioner

Using an air conditioner to cool the air inside your home is considered the main task for this household appliance, but there are split products that can work in two ways: cold and heat. There is no difference in their installation, except for small nuances: air conditioners are installed only on the walls of the house, and modern models of split systems can also be mounted in ceilings.

Many users ask the eternal question of how to set up the air conditioner yourself? The instruction interprets the basic provisions on how to properly operate the air conditioner of a certain model after the installation is completed. Set up the product using the remote control, how to properly handle it, we will tell you in detail a little later.

Device classification

All air conditioners are divided into the following main types:

  • window models. installed in the window opening;
  • wall-mounted version. consists of two blocks, the evaporator is located inside the room, and the remote one is outside;
  • floor models. installation on the floor, with hot air outlet through the window;
  • combined class.

In addition, specialists divide split systems according to functional features:

  • cooling only;
  • cold / warm;
  • work at low and rather high temperatures;
  • various additional features.

The latter option may include functions such as ionization, humidification, aromatization and air purification.

Cooling mode

We use this function constantly at home when the heat comes, so we will consider this process in more detail.

In order to turn on the air conditioner in the cold, just press the button with the snowflake, then select the optimal temperature to which you want to cool the air in the room. When the desired microclimate is reached, the remote unit turns off automatically, and the evaporator unit continues its work. it maintains the user-set parameters.

A cold stream of air exits the evaporator and fills the entire space, displacing the warmer air, which is sucked into the system and cooled. As soon as the temperature rises by a couple of degrees, the outdoor unit turns on again in order to lower it to the optimal option, which you set using the remote control on the air conditioner.

There are recommendations from experts regarding the use of the “cold” function.

  • Do not cool the air below 16 degrees in the apartment. It should be remembered that when the device is operating at full capacity, there is a risk of catching a cold.
  • The difference between the outside and inside air temperature should not exceed 5 degrees.
  • Do not turn on the product in the cold when the outside temperature is less than 12 degrees.
  • All models of modern climatic devices are tuned to save energy, this is especially true for converter products. they automatically select the operating mode.
  • All air conditioners should not be turned on at all when the outside temperature is below 0 degrees.

Many models of split units, according to the manufacturers’ assurances, can operate at 20 degrees below zero, heating the room, but they must be turned off in severe frosts so as not to break the fan. Especially carefully it is necessary to operate this technique during sudden thaws.

Correct use of PU

These remote controls are supplied with each model. Many different variations have been released today, but the labels and functions on the buttons are similar. Most users do not read the instructions, but only use the start button and temperature setting. But there are many other keys on the remote control. Let’s talk about their names and main functions.

  • Power, in some controllers on / off. turning on / off the product.
  • Mode: by pressing it once, you put the device into automatic air supply mode, twice. the product will work in cool mode.
  • Swing: activates the swing motion of the louver to diffuse the air flow throughout the space.
  • Dry, which means dry. the device operates at medium speed.
  • Fan (fan, fan). the air conditioner runs slower or faster.
  • Turbo: maximum revs and performance.
  • Temp: cold / warm temperature adjustment key.
  • Smart Saver (smart saving). when the optimal temperature is reached, the product turns off and works in fan mode.
  • Auto Clean: all parts of the device are disinfected and dried. By pressing this key once every three days (while the product works no more than half an hour), you allow it to independently get rid of excess moisture.
  • Sleep: transfer the air conditioner to semi-sleep mode, cold air spreads along the ceiling, we use it at night.
  • On Timer: turn on the timer.
  • Off Timer: turn off time.
  • Clean Air: the process of ionizing the air flow.
  • Ok: key to confirm the selected parameters.
  • Cancel: cancels the selected command.
  • Reset: reset all settings.
  • Lock: button lock (child protection).

Nuances of operation

Modern models of air conditioners are quite complex household appliances, the setting of which requires compliance with the basic rules.

  • It is necessary to clearly select the power of the product depending on the volume of the room: in regions with a very hot climate, it is necessary to install systems with a higher power, with improved characteristics of the cooling mode.
  • Always correlate the operating mode of the product with the weather conditions outside.
  • In order to prevent the occurrence of any colds, it is necessary to fine-tune the equipment in cold mode.
  • Carry out regular maintenance. these activities will allow you to ensure the normal operation of the product, and the whole family a safe and comfortable microclimate.
  • Installation, maintenance and repair of equipment should only be done by professionals.

Climate control systems can be installed in any premises, regardless of their configuration and dimensions, because modern technology copes with the task without any problems. The user should only follow all the rules and recommendations voiced in this article.

Heating mode

Modern climatic systems can supply not only cooled air to an apartment, but also heat. To do this, take PU and follow the prompts.

  • Press the Start or On / Off key, then the button labeled Heat.
  • If not, then there is a Mode key or another, above which there are symbols: snowflake, sun, raindrop and fan. Switch modes until the desired symbol appears on the display.
  • By pressing or. or the up / down arrows, you need to set the required temperature. Its value should be 5 degrees higher than the one that is currently in the room.

The fan starts up first and then the heating mode. After a maximum of 10 minutes, the product will begin to pump warm air into the room. If the control panel does not have the above-described buttons. you are out of luck, this model of the air conditioner cannot work in warm mode.

There are split systems where you first need to make all the settings, and then press the start key.

During the settings, any model is obliged to respond to your actions: give sound signals, flash LEDs. During the purchase of the product, you must familiarize yourself with all its characteristics, so that you do not rack your brains later.

Heating the apartment in the off-season

In the spring, when the radiators in the rooms “cool down,” or in the fall, when the central heating hasn’t been turned on yet, air conditioners with a heating function literally save the day. With the help of climate technology such as KAS26NFT / KAS26ZFT, you can “warm up” the temperature in the room to a comfortable number of degrees. At the same time, there are no severe frosts outside the window, which means that the climatic equipment is not threatened with failure.

How to turn on warm air on the air conditioner

For more information on how to turn on an air conditioner from LG (like P09EP), Samsung or another brand to heat, see the instructions for the device. It is imperative to study this document in order to be aware of the nuances of the operation of a particular model of climate technology.

Nuance: there are more expensive models with touch controls, for example, A09IWK. You can control the device by clicking on the remote control screen.

Correct use of the device in cold weather

Before learning how to put the air conditioner on heat and use it at subzero temperatures, you need to make sure that the “Heating” mode is provided in the device. This is necessarily indicated in the characteristics of the climate technology. For example, CH-S12XP7 can heat an apartment.

Then it is important to clarify the operating temperature range of the climatic device. For most models, it is up to 5-7 ° C. As mentioned above, inverter options can heat apartments even in severe frosts (for example, CH-S09FTXDG is capable of operating at an “outboard” temperature of up to 23 ° C).

In any case, it is possible to operate air conditioners in winter only up to the minus temperature outside the window permitted by the manufacturer. If these recommendations are disregarded, the climate equipment loses its heating capacity, and its main components quickly wear out and fail.

There is a special, so-called “winter kit”, which is equipped with the outdoor unit of the air conditioner. This includes components that heat the drainage system, keep the oil from thickening, and prevent the refrigerant from overcooling. The installation of the winter kit is carried out by specialists. The only caveat is that in such “outfit” the climatic device works in the cold. For heating, even in the winter set, you cannot turn on the device at a temperature lower than indicated in the characteristics of the equipment.

How to turn on and adjust the air conditioner to warm: 2 easy ways

Almost all types of air conditioners can not only cool the apartment, but also work in a “plus”, i.e. for heating. The air heating option will help out, for example, in the off-season, when the heating system is not functioning at full capacity or is turned off altogether.

But how to turn on and adjust air conditioners of different models for warmth? This is not difficult to do if you use the methods below. At the same time, you can find out which device is better to buy and how to use climate technology correctly in cold weather.

Which air conditioner to choose for efficient heating

There are several selection criteria:

  • Type of climate technology. If possible, you should opt for inverter devices (like I-12SPR / A18 / N1). Why? When used in winter / autumn, the air conditioner has to operate in a fairly wide temperature range. Therefore, smooth control of the compressor power is important here in order to maintain a comfortable temperature in the room. At the same time, conventional models of climatic devices (such as CH-S07XN7) can also heat the air.
  • Temperature indicators. The difference is that some inverter models can withstand overboard temperatures of 15 ° C and even lower, while ordinary models can only withstand up to 5-7 ° C.
  • Climatic adaptation characteristics. The manufacturer must provide all the necessary components for the operation of the unit in cold weather: compressor heating, anti-icing protection of the outdoor unit as in CH-S18FTXC, heat exchanger with an anti-corrosion layer as in CH-S07FTX5, etc.

Paying attention to all these points, you can choose a really standing device not only for cooling, but also for heating the air masses in the apartment.

Saving energy

In heaters, electricity is converted into heat at a rate of 1: 1. In air conditioning systems, electricity is not spent on education, but on the transfer of thermal energy. This is approximately 250-350 watts of energy = 1 kilowatt of heat. It turns out that climate technology heats the room, while spending 3-4 times less email. energy. Here, for example, ZACS / I-09HPF / saves up to 30% of electricity.

The device for the operation of the air conditioner for heat / cold

Inside the climate control equipment there is a sealed circuit through which the refrigerant flows. This substance absorbs heat during evaporation, and during condensation it releases it. The exchange of heat between the refrigerant and air masses occurs with the help of copper tubes. heat exchangers.

When the climate device operates for cooling, the internal heat exchanger acts as an evaporator, and the external part acts as a condenser. When the unit is switched to “Heating” mode, the heat exchangers are swapped. Everything works thanks to the compressor in the outer part of the climate device, which “pumps” freon through the tubes.

The benefits of air conditioning heating

Of course, certain types of climate technology can be used to heat the air in the apartment. Is it worth doing? We consider the main advantages of heating rooms with an air conditioner.

From early spring and often until late autumn, summer residents spend all their free time in summer houses and on plots. Not everyone decides to carry out capital heating for himself, since he lives in the house for only a few months and does not have the opportunity to invest a large amount of money in this business. Heating with electric heaters is also impossible due to the limit of electricity consumption due to lack of capacity. What should summer residents do in a cool spring and autumn?

What is the advantage of heating with air conditioning

As a rule, the walls of country houses consist of light structures, slightly insulated on the inside and decorated with decorative trim on the outside. Such walls are able to contain the temperature, but not accumulate it. An alternative to capital heating is air conditioning: by installing this device in different rooms, you can set different temperatures, while saving energy. Together with the low cost of heating with air conditioning, such a system has another plus. the ability to bring the temperature to a comfortable.

Due to the fact that a large volume of air is forced through the heat exchanger, the room temperature quickly reaches a comfortable value. Some air conditioners are also equipped with a voltage surge protection function, which is especially important in a holiday village with an unstable power supply. In addition, the air conditioner is able to automatically maintain the set temperature. That is, the device only needs to be set to heat or cold, set the desired temperature parameters and forget about its existence.

How to install the appliance for heating

To do this, you need to take the remote control of the LG air conditioner and, by switching the “MODE” or “HEAT” button, achieve that an icon in the form of a sun appears on the screen. Further actions consist only in setting the required temperature regime. It should be borne in mind that warm air will not blow immediately. In order for the heating function to work at full strength, it will take about 5 minutes.

The disadvantage of this heating method is that it is undesirable to turn on the air conditioner at a temperature outside the window below 0 ° C. To ensure normal operation at low temperatures, you need to take care of heating the condensate drain, because the condensate formed in the outdoor unit flows into the drainage outlet and freezes there, forming a plug. After that, the entire outdoor unit from the inside is covered with ice. As a result, the fan may fail; moreover, in such conditions, one should not expect effective heating from the air conditioner.

How to turn on the air conditioner on “Heating” or “Heat”?

During the first cold weather, many buyers have a problem with how to turn on the air conditioner for heating.

We have collected the main options for how to do this.

If the air conditioner does not turn on for heating?

If you have followed all the steps above, but the air conditioner still does not turn on for heating, then perhaps it simply does not have such a function. You can check this in the instructions for the air conditioner. If the instructions say that such a function is still provided, then contact the service company that serves you, it is possible that you need repair.

How to start the heating function?

Switching from cooling mode to heating mode is carried out with the remote control. There are several options for doing this:

  • Your remote control has a “MODE” button
  • When you press it, the “sun” icon or the words “HEAT” will appear on the display of the remote control.
  • You need to wait a bit

5 minutes, as warm air will not come out immediately

It is also possible to make all the above settings on the remote control and after that, pointing the remote control at the air conditioner, press the “ON” button.

  • If there is no “MODE” button on the remote control, but there is a button above which there are symbols: “snowflake”, “fan”, “drop”, “sun”
  • Choosing the “sun”
  • You also need to wait a bit.

5 minutes, as warm air will not come out immediately

How to set the air conditioner for heating?

After you have started the heating function, you need to set the appropriate temperature. This is done using the “” or “-” buttons on the remote control, or with the up and down keys. We recommend setting the temperature between 24 and 28 degrees depending on your preference and indoor humidity.

How to turn on the air conditioner to heat?

Before turning on the air conditioner to heat, make sure that:

1) the air conditioner has a heating function

2) the outside air temperature corresponds to the declared indicators in the instructions for the air conditioner

Each instruction manual for the air conditioner indicates at what temperatures it is allowed to operate. If you are not sure, call the company that installed or serviced your air conditioner. A conventional split system can be operated up to 5 degrees, but we advise our customers to operate up to 0 degrees. By installing a winter kit, you can use the air conditioner in heating mode and turn it on even at 30 degrees.

Which air conditioner to choose for heating?

If you plan to use the air conditioner not only for cooling the air in the summer, but also for heating in the cold season, then you should choose a model with an inverter compressor. Since the operation of the equipment will be carried out in a wide range of temperatures, a prerequisite is a smooth adjustment of the compressor capacity.

It should also be borne in mind that the device must be designed to operate at temperatures of 20. 25 C.

Only in this case, you can be sure that the manufacturer has provided all the components for work in the winter:

  • fan speed regulator in the outdoor unit;
  • the presence of a defrosting mode;
  • special version of the compressor;
  • crankcase and compressor heating;
  • heat exchanger with anti-corrosion layer, etc.

Conventional models of air conditioners for a house or apartment can also heat the air, however, their operation is allowed at temperatures up to 5 C. However, do not forget about the opportunity to “strengthen” the equipment by installing a winter kit.

Inverter air conditioners

Inverter air conditioners can be used all year round. Their distinctive feature lies in the way they control the operation of the compressor. With a decrease in temperature, performance is reduced to the required indicator by changing the speed of the electric motor.

The energy efficiency coefficient of the inverter air conditioner is 5. This means that you will receive 5 kW of heat by spending 1 kW of electricity.

Disadvantages of inverter air conditioning systems:

  • high price;
  • significant weight of the outdoor unit;
  • sensitivity to power surges;
  • more complex repair.
  • quick achievement of the set temperature;
  • practically silent;
  • it is impossible to turn on the device at temperatures below permissible.

Continuous operation of the equipment (without periodic on / off switching) saves up to 30% of electricity.

Standard models of air conditioners can be retrofitted with a winter kit, which will allow the equipment to operate at low temperatures.

The package consists of several devices, which:

  • heat up the drainage system;
  • prevent refrigerant overcooling;
  • prevent oil thickening.

The basic principle of operation of additional equipment:

  • The temperature sensor allows you to adjust the rotation speed of the fan located in the outdoor unit. With a decrease in temperature, its speed decreases. This avoids thickening (freezing) of the oil and icing of the case.
  • Compressor crankcase heating so that the unit is always ready to start.
  • Heating of the drainage system to prevent the formation of ice plugs and to effectively drain the condensate.

It would seem that a solution has been found. However, it was not there. Installing a winter kit allows you to turn on the air conditioner at lower temperatures set by the manufacturer, only for cooling.

The winter kit is most often installed in rooms that are undesirable to ventilate, but need to be cooled. For example: server and computing centers, where for the safety of the equipment it is necessary to maintain the optimum temperature.

The principle of operation of an air conditioner for heating is extremely simple. heat is absorbed during evaporation, and its release occurs during condensation.

In order to understand how the equipment heats air, you need to understand how it is cooled:

  • In the gaseous state, the refrigerant enters the compressor.
  • Under pressure, it is compressed and heated to a high temperature.
  • Refrigerant flows from the compressor to the condenser and becomes liquid.
  • The refrigerant pressure decreases and is redirected to the evaporator of the indoor unit. Here he again goes into a gaseous state.
  • The refrigerant “boils”, causing the indoor air to cool. The collected heat is “thrown” into the street.
  • The gaseous refrigerant is returned to the compressor. The cycle is closed.

In heating mode, the condenser and evaporator are swapped. This is made possible by a special valve that reverses the refrigerant flow.

How to turn on warm air on the air conditioner? Heating activation guide

You must admit that the heating system in our houses is not perfect, and often we have to heat the room on our own. Not all air conditioner owners know that the equipment can be used not only to cool the air, but also to warm it up. In this article, we will tell you in detail how to turn on warm air on the air conditioner.

Permissible temperature for heating operation

Most often, most split systems work effectively at temperatures below 5 ° C. With more severe frosts, the efficiency of the equipment decreases and there is a risk of icing of the drainage system and condenser.

The lower permissible temperature limit depends on the type of refrigerant. Some air conditioners heat the air efficiently even at 15 ° C. In harsh climatic conditions, inverter models are used, in which the intensity of the compressor can be adjusted.

Why does the air conditioner not work for heating??

First of all, you should make sure that this option is provided in the selected climatic device. If the temperature outside the window is negative, then the reason may be a compressor breakdown, freezing of oil or drainage system.

Refrigerant leakage can be another cause of malfunction. This occurs as a result of poor adhesion of the interconnect tubes. Call the service department, which will fix the problem and add refrigerant.

After installing the air conditioner, clean the filters in time. If you ignore this requirement, then damage can not be avoided. To accurately determine the source of the problem, you need to pay attention to the display screen, which displays the error code. The value can be found in the instructions.

If, 15 minutes after starting the system, air heating still does not start, try resetting the settings. To do this, once again read the instructions on how to adjust the air conditioner for warm air. Repeat all the steps from the beginning. Then turn on the system again and check its operation after 15 minutes.

The reason for the lack of heating may be an insufficient amount of freon. In this case, contact the service department.


To switch to heating mode, in Ballu air conditioners, use the MODE key. It can be located separately, or it can be located on the control joystick (see photo).

When the mode is selected, the indicators on the display of the air conditioner remote control may differ (see photo). In the first case, a schematic image will be shown in the highlighted area of ​​the screen, in the second. the arrow will point to the selected mode.

You need to press the MODE key until the sun icon appears on the display, or the selection arrow moves to the inscription “HEAT”.

How to turn on the air conditioner using your phone

To control the air conditioner from a smartphone, it must either have a built-in Wi-Fi module or be connected to the controller. You also need to download the appropriate application for your model of air conditioner or controller.

To turn on the split system to heat from a smartphone, follow these steps:

  • Turn on Wi-Fi on your phone;
  • Find a controller or air conditioner on the network;
  • Run the application;
  • Wait for the connection with the split system or controller;
  • Set the operating mode “HEAT” or “HEAT”.

After that, you just have to set the desired temperature, blowing force and adjust the blinds. If the connection with the controller or air conditioner is lost, it will continue to work in the specified mode. But to change the settings, you will need to re-establish the connection.

Oasis, Akvilon, Zerten

These split systems are equipped with universal remote controls. Therefore, it will not be possible to switch from cooling to heating mode in the usual way.

To turn on the Akvilon, Zerten or Oasis air conditioner to heat, you need:

  • Turn off the air conditioner;
  • Remove the batteries from the remote control;
  • Put them in place;
  • Turn on the remote.

An arrow will then appear on the display and will move between the two positions, COOL and HEAT. To turn on the air conditioner for heat, you need to press the MODE key when the arrow is opposite the word “HEAT”.


To turn on the heating of the Midea air conditioner, use the MODE button. The operating mode for heat can be displayed as:

  • Arrows opposite the word HEAT on the side panel (see photo);
  • The sun on the display (see photo);
  • The marked name of the HEAT mode on the display (see photo).

How to turn on the air conditioner for heating without a remote control

Many models of split systems have an active control panel on the indoor unit. It can be touch-sensitive or ordinary, in the form of buttons. Sometimes it is hidden under a plastic cover.

If the buttons or control sensor are not visible, you need to open the front cover of the air conditioner. To do this, find grooves or protrusions under the fingers in its lower part on the right and left and pull it towards you and up (see photo).

Once the control panel is visible, it may not have an ON / OFF button. To turn on the air conditioner without a remote control, you need to use a hidden button. It is located on the panel to the right of the air filter. It can be marked as “ON / OFF” or “AUTO”.

To turn it on, you need a regular pen. Depending on the diameter of the hole, reach for the button with either the stylus or the back. To turn off the air conditioner, follow the same procedure.

Why does the air conditioner not blow warm air

If the air conditioner does not work for heating, two options are possible: incorrect setting or breakdown of the split system. Let’s take a look at them.

Some models switch to heating mode as soon as you set a high temperature, for example, 28 ° C. But for most, you first need to go to the “HEAT” mode.

Each air conditioner needs 3-5 minutes to switch from cold mode to heating mode. At the same time, newer models turn off the fan and stop blowing. In older ones, the fan can continue to blow cold air around the room for some time. You just need to wait a little.

If the outside temperature is too low, the split system will not be able to heat the air. Check in the manual or manual if your air conditioner can run on heating in such frost. If not, nothing can be done, you will have to use heaters or heat the fireplace.

If you performed the switch correctly, waited and the air conditioner did not start working on heat, there are several possible reasons:

  • Not enough freon in the line;
  • The temperature sensor is out of order;
  • The outdoor unit is clogged with debris;
  • The indoor unit is dirty;
  • The fan is not working well;
  • The compressor is out of order.

Read more about the problem and how to solve it in the article Why the air conditioner does not heat, blows badly, heats poorly. In some cases, the most you can do is clean the air conditioner yourself. If this does not help, you need to call a specialist.

How to switch a split system to warm air

To turn on the air conditioner for heating, you need to use the remote control:

  • press the power button (“On / Off”);
  • find the “HEAT” button and press it;
  • if there is no “HEAT” on the remote control, there must be a “MODE” button (switching modes) or any other button, above which a droplet, snowflake, sun and a fan are drawn;

If there is neither the sun nor the words “HEAT” on the remote control, but there are other modes and are displayed, this means that your split system cannot heat the room.

  • switch modes until the sun appears on the screen or the inscription “HEAT”;
  • using “” and “-” (or arrows up and down), you need to set the desired temperature. It should be higher than the one in the room now;
  • first, the fan usually turns on and only then the air begins to heat up;
  • after 5 (maximum 10) minutes, the air conditioner should start working on warmth.

On some models, they first set up the data on the remote control and only then press the On / Off button. Remember that the split system must necessarily respond to your pressing: (beep, blink, turn on and off).

Even if you have the sun or the inscription “HEAT”, this does not guarantee that the air conditioner will help heat the room. Sometimes manufacturers use standard remotes for all of their devices. It is better to clarify the characteristics of your particular model.

Safety engineering

Remember not to put the air conditioner on warm air if the outside temperature is too low. So, some models work at temperatures not lower than 5….8 degrees Celsius. If you turn on the heat in severe frost, icing of the outdoor unit is possible and, as a result, breakdown.

An inverter air conditioner (with a winter kit) can also operate at lower temperatures. It can be put on heat at 10….15 degrees Celsius. Of course, the split system alone cannot cope with heating an apartment or house, and therefore must be used in conjunction with radiators.

Air conditioner: how to turn on the heating mode

If you want to set the air conditioner to warm, but have lost the instructions and do not know how to do it, do not worry. All such devices work in about the same way, and therefore you can turn on the heat if you use our advice. But first, make sure that your air conditioner can still be configured for heating: not all models allow you to do this. You can find out about the characteristics of your device on the Internet by typing the brand and model of the split system in the search engine.

What to do if the air does not heat up

If 10 or even 15 minutes have already passed, and the air conditioner still has not started producing heat, then either it is not designed for this, or something has broken in it. There may also be another reason: you have not been able to correctly set the settings. Try to do it all over again, carefully reading our instructions and listening to the reaction of the split system. 10-15 minutes after switching on, bring your hand to the device and check if it is warm.

Sometimes the sun or the inscription “HEAT” seems to slip through, despite the fact that you press the button correctly. You may need to change the batteries or just pull them out and insert them again for the system to work properly.

If the system is low on freon, it will also not be able to heat the room. In this case, you will have to contact a repair shop.
