Correct setting the temperature is not just a matter of comfort, but a critical parameter for the safety of products and the durability of the unit itself. Owners of Belarusian equipment are often faced with the need for calibration after the first purchase or when the seasons change, when the room temperature changes. Incorrect settings can lead to rapid spoilage of food or, conversely, to the formation of an ice crust that will have to be defrosted.
The brand's model range Atlant covers both classic two-chamber systems with manual defrosting, and modern solutions with the system No Frost. The configuration principles in them differ significantly, and knowledge of these nuances will help to avoid typical operating errors. In this article we will analyze in detail the mechanical and electronic methods of controlling the climate inside the chambers.
It is worth noting that the factory settings are often averaged, and for maximum efficiency thermostat individual adjustment may be required. Understanding the physical processes of cooling will allow you to optimize compressor performance and reduce energy consumption. Let's look at how exactly the cold is controlled in various modifications.
Features of thermostats in different models
The basis for climate control in refrigerators Atlant are two fundamentally different types of devices: mechanical thermostats and electronic control units. Mechanical controls, often found in classic models, are a rotary switch with a scale from 1 to 7 (or from Min to Max). Here the number does not indicate degrees, but the intensity of the compressor: the higher the number, the colder.
Electronic control is typical for more modern series and allows you to set the exact temperature in degrees Celsius. Such systems are often equipped with displays on the door, which display the current parameters of the main chamber and freezer separately. Digital sensor Reacts to the slightest changes, ensuring stability of the regime, which is especially important for storing perishable products.
It is important to understand that a mechanical thermostat operates on the principle of opening the circuit when a certain temperature is reached, while the electronics continuously monitor the state of the environment. An error in setting the mechanical regulator can lead to the compressor working non-stop, trying to achieve an impossible minimum.
A critical feature of mechanical models: setting the knob to maximum (7 or Max) in a warm room can lead to continuous operation of the motor and evaporator freezing. Electronic systems are safer in this regard, as they have software restrictions and protection against overheating.
- 🔹 Mechanical regulators require periodic manual adjustment depending on the season.
- 🔹 Electronic panels allow you to set the exact temperature regime for each zone separately.
- 🔹 Models with No Frost often combine mechanical and electronic controls.
⚠️ Attention: If you have an electronic display, do not try to turn the hidden mechanical calibration screws without special equipment - this will ruin the controller's factory settings.
Setting the mechanical temperature controller
If your refrigerator is equipped with a rotary knob inside the main one cameras, you are dealing with a classic thermostat. The scale is usually graduated from one to seven, with "1" being the minimum cooling (warm) and "7" being the maximum (very cold). The optimal position for year-round operation is considered to be 3 or 4.
To change the mode, you must turn the handle in the desired direction. This should be done smoothly, without sudden jerks, so as not to damage the internal spring group of the thermostat. After turning the knob, do not expect an instant result: stabilization of the temperature in the chamber takes from 2 to 5 hours.
In the summer, when the ambient temperature in the kitchen is high, it is recommended to shift the regulator towards higher values (4-5) to compensate for the heat gain. In winter, on the contrary, you can reduce the intensity to 2-3, since the environment is already cool, and the compressor does not need to work hard.
There is a common misconception that the number on the regulator corresponds to degrees Celsius. This is not so. Position"3" usually maintains about +4...+5°C in the center of the chamber, but the actual temperature depends on the load of products and the frequency of opening the doors. If you notice that the milk is souring faster than usual, try increasing the value by one.
Control of the electronic unit and display
Modern models Atlant are often equipped with a control panel located on the outside of the upper door. Here, customization occurs by selecting specific numeric values. To enter the editing mode, you usually need to briefly press the button with the image of a thermometer or the setting symbol.
After activating the setting mode, the indicators begin to flash, indicating the current target value. Using the "+" and "-" buttons (or up/down arrows) you set the desired temperature. The standard value for the main camera is +3°C or +4°C. For the freezer, the optimal mode is considered -18°C.
Electronics allows you to use special modes such as “Super Freeze” or “Vacation”. The mode "Super Freeze" forces the compressor to work continuously for a limited time, quickly reducing the temperature of the food. The "Vacation" mode turns off the main chamber, leaving only the freezer active, which saves energy while you are away.
Some models have a child lock button function, which is activated by long-pressing a special key. If the display is lit but the buttons are not responsive, check to see if this security mode is activated. Resetting settings to factory settings is often possible by long-pressing a combination of buttons.
| Mode | Temperature (Main) | Temperature (Frost) | Purpose |
|---|---|---|---|
| Standard | +4°C | -18°C | Daily storage |
| Eco | +5...+6°C | -16°C | Energy saving |
| Super freezing | +2°C | -24°C | Fast cooling |
| Vacation | Disabled | -18°C | Long absence |
☑️ Checking the display settings
Adjustment in refrigerators with the No Frost system
Appliances with the system No Frost requires a special approach, since the circulation of cold air here is forced. These models often use one common thermostat or sensor located in the main chamber, but controlling the operation of the evaporator, which may be located in the freezer or behind the back wall.
It is important not to block the ventilation holes inside the chamber with food. If you have set the correct temperature, but the air does not circulate, the sensor will show the norm, and there will be heat in the depths of the chamber. Air duct damper regulates the flow of cold, and its jamming with food will lead to local overheating or, conversely, freezing of vegetables at the flow outlet.
B models Atlant with two compressors (separate for each chamber), the temperature settings in the freezer and refrigerator compartment are completely independent. If there is only one compressor, then priority is always given to the freezer chamber, and cold is supplied to the main chamber according to the residual principle through the channel.
When configuring No Frost systems, extreme values should be avoided. Setting the minimum temperature may cause the food at the back wall of the main chamber to become covered with frost, despite the absence of classic ice. It is optimal to keep average values and monitor the loading density.
⚠️ Attention: In No Frost systems, you cannot seal the ventilation grilles on the back wall of the chamber with masking tape or stickers - this will disrupt the defrosting algorithm.
Seasonal adjustments and environmental influences
A refrigerator is a heat pump, and its efficiency directly depends on the temperature difference between inside and outside. In summer, when the kitchen is +25°C or higher, heat exchange is difficult. During this period, it may be necessary to shift the regulator by 0.5-1 division towards increased cold in order to compensate for the heating of the case.
In winter the situation is the opposite. If the refrigerator is in an unheated room or next to a window where the temperature drops, the standard settings may be too much. The compressor will turn on rarely, and the temperature in the main chamber may rise above the safe one, even if the regulator is set to “minimum”.
There is a concept of “climate class” of equipment. Most models Atlant belong to the class SN-T (subnormal - tropical), which means operating in ambient conditions from +10°C to +43°C. If the room temperature drops below +10°C, the thermostat may stop turning on the motor, because it “thinks” that it is already cold inside.
The winter period is also characterized by the problem of condensation. When there are sudden changes in temperature outside and indoors, moisture may form on the walls. In this case, do not rush to turn the regulator - check the tightness of the seal and the absence of drafts blowing on the equipment.
Why may the refrigerator not turn off in winter?
If the room is very cold (below +10°C), the oil in the compressor thickens and the freon pressure drops. The thermostat may not sense the temperature difference and keep the motor on.
Diagnostics of problems with temperature conditions
If you have set the settings according to the instructions, but the temperature does not correspond to the set one, it is necessary to carry out diagnostics. The first sign of a malfunction is the nature of the compressor's operation: either it hums continuously or is silent for too long. The normal operating cycle includes periods of activity and rest.
A frequent problem is the freezing of “coat” or ice on the back wall of the main chamber in models with a drip system. If the ice layer exceeds 5-7 mm, this is a signal that the thermostat does not turn off the compressor in time, or the drain hole is clogged. In models No Frost there should be no ice at all.
You can check the real temperature using a household thermometer placed in a glass of water in the center of the chamber. Leave it for several hours. If the readings of the thermometer and the display (or regulator) diverge by more than 2-3 degrees, calibration or replacement of the temperature sensor is required. It is also worth paying attention to the products. If the ice cream has become soft and the temperature in the freezer is set to -18°C, there may be a freon leak or a fan malfunction. If the vegetables in the main chamber freeze, it means that the flow of cold air is directed directly at them or the damper does not close. temperature sensor.

- ❄️ Ice on the back wall of the main chamber indicates a malfunction in the defrost cycle.
- ❄️ Warm food with the motor running may indicate a leak refrigerant.
- ❄️ Constant operation of the compressor is often caused by incorrect installation of the regulator or a malfunction of the thermostat.
⚠️ Attention: If after defrosting within 24 hours the temperature does not stabilize and the compressor runs constantly, do not try to further turn the regulators, a call is necessary master.
Frequent questions and answers (FAQ)
Why does ice freeze in the Atlant refrigerator, although it is set to No Frost?
The system No Frost prevents ice formation only if all components are working properly. Ice may be caused by a door that is not closed tightly, a broken defrost heater, a faulty timer, or a clogged drain. Ice will also appear if you put hot foods in the chamber or opened the door for a long time.
What temperature should you set in the freezer for long-term storage of meat?
For long-term storage (up to 12 months) of meat and poultry, the optimal temperature is -18°C and lower. At a temperature of -12°C, shelf life is reduced to 3-4 months. The "Super Freeze" mode (-24°C) is used only for quick freezing of fresh food; it is not recommended to keep it constantly.
Is it possible to configure the Atlant refrigerator via a smartphone?
Most classic models Atlant do not support control via Wi-Fi or Bluetooth. The Smart Home function is found only in the newest premium series. For the majority of equipment, adjustment is made exclusively through the control panel on the case or a mechanical regulator inside.
What to do if the temperature regulator scrolls endlessly?
If the mechanical thermostat knob rotates without clicks or restrictions, this is a sign of a breakdown of the thermostat itself (destruction of the internal mechanism). It is impossible to operate the refrigerator in this mode, since it either will not turn on or will work without stopping, which will lead to spoilage of food or burnout of the motor.
