Belarusian-made refrigerators Atlant are deservedly popular due to their reliability and affordable cost, however, temperature control in different models differs significantly. Owners are often faced with the need to increase freezing before loading a large volume of products or, conversely, reduce the compressor power to avoid excessive freezing. Understanding the operating principles of your unit is the key to the long life of your equipment and maintaining the quality of products.
Before taking active steps, you must clearly identify the type of control installed on your device, since the setting algorithms for mechanical and electronic systems are radically different. Incorrect adjustment can lead not only to inventory damage, but also to overload of the compressor, which in the long term reduces the life of the motor. In this article we will analyze in detail all the nuances of adjustment for various series of refrigerators.
The main task of the user is to find a balance between energy consumption and storage quality. The temperature in the freezer should be stable and fluctuations should be minimal. Let's look at exactly how the cold control system is designed in different modifications and what tools are provided for this by plant engineers.
Determining the type of temperature control system
The first step should always be a visual diagnosis of the control panel. In refrigerators Atlant there are two main types of systems: mechanical and electronic. The mechanical system is controlled by a rotary control, which is usually located inside the refrigerator compartment or on the top panel of the cabinet. Electronic means there is a digital display and touch buttons on the front door.
If you find a round disk inside the camera with numbers from 1 to 7 or from Min to Max, then you have a mechanical control. In this case, thermostat reacts directly to the air temperature inside the refrigerator compartment, and the freezer is cooled according to the residual principle. This means that changing the position of the handle affects the operation of the compressor as a whole, but it is impossible to set the exact temperature in the freezer in this way - it depends on the load and external conditions.
⚠️ Attention: In models with mechanical control, the numbers on the regulator do not indicate degrees Celsius. One is the minimum power (least cold), and the maximum number (usually 7) is the maximum freezing mode.
In models with electronic control, such as series XM-4425 or XM-6025, the situation is different. Here you can set exact values for each compartment independently of each other thanks to the system No Frost or improved static cooling. The display displays the current parameters, and changes occur step by step using buttons.
Setting a mechanical thermostat
Temperature adjustment in models with one compressor and mechanical control requires an understanding of the physics of the process. Since the sensor is located in the refrigerator compartment, it is there that the achievement of the set temperature is monitored. When the air in the main chamber is cooled to the desired limit, the compressor turns off and the freezer stops receiving cold.
In order to lower the temperature in the freezer, you need to turn the dial towards higher values. However, it is worth remembering that this will lead to longer operation of the compressor and, accordingly, to a decrease in temperature in the refrigerator compartment. Optimal position For everyday work, the average value is considered, usually the numbers 3 or 4.
There is a special mode, indicated by a snowflake or number 7 (depending on the model), which is intended for quick freezing of fresh food. In this mode, the compressor operates continuously without switching off by timer. Using this mode for more than 24 hours is strictly not recommended, as this causes critical wear of the motor and can lead to freezing of the evaporator.
☑️ Algorithm for setting up the mechanics
It is important to take into account seasonality. In the summer, when the ambient temperature in the kitchen is high, it may be necessary to set the regulator to a more powerful value to compensate for the heat gain. In winter, on the contrary, the load on the system drops, and the power can be slightly reduced.
Control of the electronic unit and display
Electronic refrigerators Atlant provide the user with much more opportunities for fine-tuning. Control is carried out through a panel located on the outside of the door. Here you are dealing with digital sensorsthat control the temperature directly in each chamber (if the model is two-compressor) or in the evaporator zones.
To change parameters, you usually use a mode selection button or a separate key for each compartment. Pressing activates the blinking of the indicator, after which the desired value is set using the “+” and “-” buttons. The standard freezer temperature is -18°C. This value ensures long-term storage of meat and fish without losing their properties.
Some modern models are equipped with a function Smart Control or the ability to control via a smartphone, but the basic setting is always available on the case. If you change the settings, the system may go into the parameter saving mode, and the new values will not take effect immediately, but after several operating cycles.
| Operating mode | Temperature in the freezer | Temperature in the refrigerator compartment | Recommended use |
|---|---|---|---|
| Standard (Eco) | -18°C | +4°C... +5°C | Daily operation |
| Maximum cooling | -24°C | +2°C... +3°C | Loading a large volume of fresh food |
| Holiday | -18°C | +15°C | Long-term absence of owners (freezer only) |
| Super freezing | Up to -30°C | No change | Short-term intensive freezing |
When using electronic control, you should be careful with frequent mode changes. Sharp changes in settings force the system algorithmic control to recalculate operating cycles, which in the first hours may be accompanied by noisier operation of the fans or compressor.
Super Freeze mode and its features
The super freeze function (often indicated as Super Freeze or a button with a picture of a snowflake) is a powerful tool, but requires a competent approach. Its main purpose is to quickly freeze freshly loaded food without defrosting the supplies already in the chamber. When this mode is activated, the temperature in the freezer compartment is forcibly reduced to the lowest possible values (usually from -24°C to -30°C).
In mechanical models, this mode is often implemented by forcibly turning on the compressor, bypassing the thermostat. In electronic ones, a program setting is set to an extremely low temperature. The operating time in this mode is limited: in most models Atlant the system will automatically turn off super freezing after 12-24 hours, returning the previous settings.
⚠️ Attention: Do not leave the super freezing mode turned on permanently. Prolonged operation at extremely low temperatures leads to over-drying of food (freezer burn) and a significant increase in energy bills.It makes sense to use this function only when the chamber is fully loaded with warm or cooled products. If you plan to freeze just a couple of bags of berries, this is not necessary - the standard mode will be enough to compensate for the heat gain.
What happens inside during super freezing?
When this mode is enabled, the system ignores standard shutdown cycles. In No Frost models, fans operate continuously, blowing out the coldest air possible. In drip systems, the compressor does not stop until the timer expires or the user manually turns the function off. This creates a peak load on the motor windings and the starting relay.
The influence of loading and location of products on temperature
Even a perfectly tuned refrigerator will not work effectively if the rules for its loading are violated. Circulation of cold air is a fundamental operating principle of any refrigeration equipment. In the freezer compartment Atlant, especially in systems No Frost, air should freely wash all products.
If you fill the chamber to capacity, blocking the outlet openings of the air ducts, the temperature sensors may show incorrect data. Cold air will remain at the top or outlet, while the temperature in the depths of the chamber will be higher than normal. This will lead to the compressor working longer than necessary, trying to cool the “warm pocket.”
On the other hand, a completely empty freezer is also not good. Frozen foods act as cold accumulators (heat-intensive mass). They help keep the temperature stable when the door is opened. If the chamber is empty, with each opening, cold, heavy air quickly flows out, being replaced by warm air, and the compressor has to re-cool the entire volume.
- 🧊 Leave 2-3 cm gaps between the bags for free air circulation.
- 📦 Do not close the ventilation grilles on the back wall of the chamber products.
- 🥩 Distribute warm foods evenly, without dumping them in one pile at the sensor.
- ❄️ Use containers for small items so that they do not block the air flow.
Typical problems and their solutions
Sometimes users are faced with a situation where the adjustment does not give the expected result. For example, the regulator is turned to maximum, but the temperature in the freezer is insufficient. This may indicate a refrigerant leak or loss of compressor performance. In such cases, simple calibration will not help - diagnostics by a specialist is required.
Another common problem is the formation of an ice coat even with the correct settings. Often the reason lies in a loose fit of the door rubber seal. If warm air is constantly sucked in, the system will work in enhanced mode, but will not create stable cold. Check the cleanliness of the seal and the integrity of the magnetic tape.
In electronic models, malfunctions in the temperature regime can be caused by a malfunction of the temperature sensor (thermistor). If the display is on, but the temperature does not change or there is an error (flashing indicators), most likely, the controller received incorrect data from the sensor.
Seasonal adjustment and energy saving
The ambient temperature directly affects the efficiency of the refrigerator. In the summer, when the kitchen is +25°C or higher, heat exchange in the condenser (radiator at the back or on the sides) worsens. To maintain the set temperature in the freezer, the compressor has to work harder. During this period, it makes sense not to set the regulator to minimum values in order to prevent defrosting.
In winter the situation is the opposite. If the refrigerator is located in an unheated room or near a cold external wall, the temperature difference between the chamber and the environment is smaller. This has a beneficial effect on energy consumption. However, if you have a single-circuit refrigerator, in winter there may be a problem with insufficient cooling of the freezer if the regulator is set to minimum.
Energy-saving modes in modern ones Atlantakh optimize operation by slightly increasing the temperature within acceptable limits (for example, to -16°C or -17°C), which does not affect the quality of storage, but saves electricity. For long-term storage (more than 3-4 months), it is still better to keep the standard -18°C.
Why does the temperature not change immediately after adjustment?
The refrigerator is an inertial system. After changing the position of the regulator or adjusting the display, time must pass for the new volume of refrigerant to circulate through the system, cool the evaporator and transfer the cold to the products. Depending on the camera load, this process can take from 4 to 12 hours. You should not turn the regulator back and forth in anticipation of a quick result - this will only disrupt the operating algorithms.
Is it possible to use external thermometers for control?
Yes, this is a great way to check the accuracy of your refrigerator. Place a regular household thermometer (or a special one for freezers) between bags of food, leave for several hours and compare the readings with the settings. This will help you understand how accurately the built-in electronics or mechanics of your unit work.
What to do if the freezer freezes too much even at minimum?
If even at the weakest setting (number 1) the food freezes and the compressor works with short cycles, the thermostat itself may be faulty (contacts are stuck) or lost elasticity of the bellows tube of the sensor. In this case, the thermostat needs to be replaced, since it will no longer be possible to regulate the temperature using standard methods.
