How to turn on the 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 hypostases: 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 be mounted in the ceiling overlaps.
Many users ask an eternal question how to set conditioner by themselves? The instruction interprets the main points how to operate correctly the air conditioner of certain model after the installation is finished. Adjust the product with the help of remote control, we will tell you how to operate it in details later.
Cooling mode
This is a feature we use all the time at home when the heat comes on, so let’s take a closer look at this process.
In order to switch on air conditioner in cold mode, you just need to press the button with snowflake icon, then choose optimal temperature up to which you want to cool air in the room. When the desired microclimate is reached, the remote unit switches off automatically, and the evaporator unit continues its work. it keeps the parameters set by a user.
A cold stream of air exits the evaporator and fills the entire space, displacing the warmer air that is sucked into the system and cooled. As soon as the temperature goes up a couple of degrees, the outdoor unit starts up again to bring it down to the optimum value you set with the remote control on the air conditioner.
There are recommendations from experts on the use of the “cold” function.
- You should not cool the air in your apartment below 16 degrees. It should be remembered that when the device is working at full power there is a risk of catching a cold.
- The difference between outdoor and indoor air temperature should not exceed 5 degrees.
- It is not a good idea to turn the product on when the outside temperature is less than 12 degrees.
- All models of modern climatic devices are configured to save energy, especially converter products are distinguished by this. they automatically select the mode of operation.
- All air conditioners in general should not be turned on when the outside temperature is below 0 degrees Celsius.
Many models of split units, according to statements of manufacturers, can work at 20 degrees below zero, heating a premise, but it is necessary to switch them off at strong frosts not to break the fan. Use this appliance with particular care during a sudden snowstorm.
Heating mode
Modern climate control systems not only provide cool air but also warm air. To do this we take the PU and follow the prompts.
- Press Start or On/Off, then the button labeled Heat.
- If there is not one, then there is a Mode key or other key, above which there are symbols: snowflake, sun, raindrop and fan. Change modes until the desired symbol appears on the display.
- By pressing the or. or up/down arrows to set the desired temperature. Its value should be higher by 5 degrees than the one that is now in the room.
First the fan is activated, then the heating mode. After no more than 10 minutes the product will blast warm air into the room. If on DU is not available the buttons described above. you are out of luck, this air conditioner model can not operate in a warm mode.
There are split-systems, where it is necessary to make all settings at first and then to press start button.
During adjustment any model must respond on your actions: sound signals, blinking of light-emitting diodes. During the purchase of the product it is necessary to get acquainted with all of its characteristics, so that then do not break your head.
Air conditioning in heating mode
Before turning on the unit in heating mode, you must make sure that the operation of the air conditioner in heating mode is maintained. If there is no documentation to conditioner, it is necessary to find in Internet description of that air conditioner model, where everything is described in details. Also air temperature outside should correspond to parameters, which are fixed in operation manual.
Every split-system has different principle of conditioner‘s work on heating. Meaning the temperature level at which the device can be turned on. The most common air conditioner can be turned on at a temperature of up to 5 degrees Celsius. But there are also new models, in which heating by air conditioner is allowed at the temperature of.25 degrees Celsius.
When the mode “heating” is switched on at first cold air comes in, but in 5-10 minutes it begins to warm up. Not everybody knows about this peculiarity and that is why they start to press the button “heating mode” intensively. But such maneuvers are detrimental to the device. In order to avoid similar misunderstandings, it is necessary to wait from 5 to 10 minutes after turning on the heating mode. This time will be enough to warm up the inside block and then the air will start to warm up.
Besides the external block of split-system has a peculiarity. at low temperature it starts to freeze. And then automatical defrosting is started. The principle of work is that during ten minutes the fans are stopped, and through the special tube the thawing water is coming out.
Changing of air conditioner to the warm mode
It is necessary to use conditioners with the strict observance of the most necessary norms. This action will provide prolongation of service life up to the maximum and will relieve owners of climate control equipment from necessity of expensive and frequent repair, which is usually held with replacement of expensive parts like compressor or control board.

To set the air conditioner to heat (heating), you need to:
1 Option:
1) Look into remote control, there is “MODE” button (some remote controls have a hidden cover).
2) Press “MODE” button until there is no “sun” or “HEAT” sign on the display.
4) When you change modes, hold the remote control toward the air conditioner so that it receives signals as you set and makes a sound confirming the signal.
It is also possible to do all the above-mentioned settings on the remote control and then direct the remote control to the conditioner and press “ON” button.
6) In the warm mode, the fan of indoor unit does not turn on immediately!
2 Option:
1) Looking into the remote control, there is no “MODE” button, but there is a button above which there are symbols: “snowflake”, “fan”, “drop”, “sun”.
3) Set the temperature above the room. (Example: your room is 20 degrees). put 25 or 27).
4) As well as in the 1st variant, we switch on air conditioner; it should “squeak” with characteristic sound in each case differently. When a wire remote control is usually silent, but at switching on the conditioner the lamps light up.
5) Go drink tea, if you do not want to just wait five minutes.
3 Variant:
You do not see “HEAT” or “sun” icon on the remote control, but other modes are displayed.
This tells you that your air conditioner is not able to bring warmth to your house. You only have it working for cold.
4 Option:
You are sure that the conditioner is warm-cold and not only cold.
You did all of the above steps.
Conditioner is switched on, the heat mode is set, the temperature is raised above about 30C., The air conditioner has beeped or the lights on the inside unit have turned on.
Air conditioner does not give the heat and it is on for 30-60 minutes.
I am sorry but you need a repair of a conditioner.
Before installing the air conditioner it is necessary to study in detail the instruction manual, which describes the best way to perform these actions, as well as how to turn on the air conditioner for heat. Specialists advise not to save on such important actions as installation, and to trust the professionals. But it is necessary to understand the elementary functions by yourself.
How to operate Air Conditioner on Heating Mode
Main modes
Most of conditioners keep the basic condition. cold, but more modern models can make a heating.

Filtration: all devices are equipped with a filter. Types of filters can vary depending on the type of the system and the needs of the clients. Filtering efficiency range: from dust and other particles to dust, bacteria, viruses and odors, germs and smoke
It is important to replace the filters after the specified time. If the filters are replaced too late, there is a risk that contaminated unspecified filters will begin to return bacteria to the air rather than stop them
Edit: Choosing the right capacity ensures that no drafts are formed. This is a specialist task and should be done by an assembler. Low-efficiency system will not be able to maintain the desired temperature. A system with too much capacity will cause drafts and temperature fluctuations.
The nuances of operation in a cold season
Our goal is to get warm without ruining the appliance we are about to use. To achieve it is very simple. you need to listen to the opinion of the manufacturer, which is contained in the instruction manual of the product.
The temperature range in which the product will work effectively and stably is specified. For most models. from minus 5 to plus 25 °C.
But in summer we often switch on a conditioner even at high ambient temperatures. The consequence of such excessive temperatures is a decrease in unit performance. However, it does not break down. In winter, the violation of the recommended operating conditions can lead to very disastrous results.
Why does this happen?? In the most popular models the condenser and compressor are situated in the outdoor unit.
When the temperature falls below the temperature stated in the instruction, the aggregate condition of oil in the compressor crankcase changes too: it becomes dense and it stops to envelop moving elements of the device. This has a negative effect on their service life.
Frosted external block of a split-system indicates that exploitation of the given device is postponed till its complete release from ice captivity
By the way, in summer, too, disturbance of the regime does not pass completely unnoticed. If the outdoor unit is on the sunny side of the system, it is subjected to serious overheating, which can also cause the oil to thicken. In this case, the rubbing parts, which are deprived of lubrication, wear out faster.
When performing the heating function, heat from the environment must be transferred to the room. It is the refrigerant, moving through the condenser of the outdoor unit (or evaporator), that gets it from the outside air. If the temperature of this air is too low, the freon does not heat up as much as necessary, and the thermal efficiency of the split system drops.
In addition, the evaporator-condenser and compressor become hot during operation. When in contact with cold air masses the surface of parts becomes covered by condensate, which quickly turns into icy deposits. In such conditions the device simply stops working.
But this is not the only reason of its failure. Frosty air leads to failure in phase transitions of the refrigerant. Freon does not become gaseous in the evaporator as it should under operating conditions. If it enters the compressor in this condition, it can cause a hydraulic shock.
The reason of icing of the device can be caused not only by mistakes in its operation mode but also by precipitations which can be prevented by the same visor protecting the device in time
When the air conditioner works in a cooling mode, there is a big air flow through it. When it is in contact with the condenser and evaporator surfaces, the condensate is formed, which is discharged outside by means of drainage system. The drain hose is used to drain down at an angle.
If you turn on cooling mode in winter, we risk to get a plug of frozen water in the drain hose. Condensate that stopped to outlet outwardly will inevitably come in a conditioner, break its work.
Of course, expansion of a temperature range for safe operation of products is one of the first-priority tasks of all models producers. For this purpose, for example, systems of compressor oil heating or drainage heating are installed. The result is impressive.
For example, TOSHIBA products specifically designed for northern countries can also be successfully operated at.20°C.
Turning on the air conditioner to cool:
At adjustment of some conditioners this figure can change in a couple of seconds (showing current temperature in the room);
- Then, if necessary, change the shaft speed with the “fan” button;
- We can adjust air stream direction by “swing” button.
- air conditioner will not cool down if temperature in the room has reached the set temperature;
- when using the remote controller, always point it at the air conditioner.
Free tip: when using the air conditioner, you do not have to turn it off at night or when you get cold. It is better to set the optimum temperature. So you will be comfortable and conditioner will work in its normal mode. For example, you can increase the set temperature by 1-2 degrees at night.
How to switch the work of conditioner “on heat” read in the following article.
The climate control systems help to create the optimal temperature in a premise, but not all users know the basic rules how to use the conditioner in order not to harm the health of people living in the house. Let’s consider how and in what mode air conditioner must be switched on to have the optimum temperature indoors.
From early spring and often until late autumn suburbanites spend all their free time in summer houses and plots. Not everyone dares to make a capital heating, because he lives in the house for several months and has no opportunity to invest a large sum of money. Heating by electrical heaters is also impossible because of power consumption limit because of power shortage. What should dacha residents do in the cool spring and fall seasons?
The question posed by this section has one background. Namely all conditioners of “winter-summer” type, they are split-systems, can be used as a heating device. often, as an auxiliary to the basic heating network. But they can work only at a certain temperature. That is the manufacturer accurately specifies the minimum temperature condition at which one can use conditioners.
Most often it is minus 5-10C. At inverter models this limit is a little bit lower. up to minus 15°C. That is, if the temperature outside is lower than these parameters, it is forbidden to turn on the device. Just the icing of the outer block will happen, which will lead to its failure.
Every air conditioner is created, first of all, in order to make it work for cooling air mass in the premise. You can switch to this mode by pressing the button with the snowflake on it, which means “cold“.
Useful to know! Coolness comes through a physical process, or more precisely, the transformation of a substance (refrigerant, freon) from liquid to gaseous state.
When a conditioner works in a cooling mode, it is switched on by temperature increase in a premise. Once the degrees have reached their set value, the compressor in the external module (if it is a split system) is switched off. For better comfort, the fan speed in the indoor unit is automatically adjusted according to the room temperature.
The speed of the outdoor fan varies depending on the condenser condition of the outdoor module. As soon as the release of moisture decreases, and thus the pressure inside the tubes drops, the compressor is switched on and the fan, which is outside, increases its speed.
At this point, the warm air generated around the condenser is discharged outside and the icy refrigerant is forced into the evaporator of the indoor unit. Heat exchanger is made in the form of a radiator (copper pipes are jointed together with aluminum plates). Cold air passing through the louvers is dispersed by a fan throughout the room.
