Correct setting temperature conditions are the foundation for the safety of your products and the long service life of household appliances. For owners of Belarusian equipment, the question of how to set the temperature in the Atlant refrigerator often arises immediately after purchasing or seasonally changing food supplies. Incorrect settings can lead to rapid spoilage (spoilage) of food or, conversely, to excessive energy consumption and freezing of food.
Modern models of the brand, whether two-chamber Atlant XM 4008 or older series, have their own control features. In this article we will analyze in detail mechanical thermostats, digital control panels and the nuances of the No Frost system. You will learn to determine the optimal values for each compartment and understand why standard factory settings may not be suitable for your kitchen.
It is important to immediately note that the operating principle of the refrigeration unit is based on refrigerant circulation, and the user’s task is only to adjust the operation of the compressor through the thermostat. Precise calibration allows you to avoid unnecessary load on the motor, which directly affects the service life of the device. Let's figure out how to achieve the ideal balance between cold and energy efficiency.
The principle of operation of the Atlant thermostat
The basis for controlling the climate inside the chamber is a thermostat, or thermostat. In mechanically controlled models, such as the popular Atlant MXM 2808, this device is a rotary switch. It does not show degrees Celsius directly, but regulates the threshold for turning the compressor on and off. The higher the number on the scale, the lower the temperature inside the chamber, since the compressor will work longer without turning off.
Digital models, for example, series Atlant XM 4425, equipped with an electronic control unit. Here the user sees the exact values in degrees, and the sensors independently control the climate in each zone. The electronics allow you to set different modes for the upper and lower compartments independently of each other, which is impossible to do on a mechanic with one regulator.
It is worth understanding that the thermostat reacts to the temperature of the evaporator or air in the chamber, but not instantly. After any turn of the knob or change of setting on the display, time must pass for the system to stabilize. Thermal inertia is a physical property that cannot be ignored when setting up.
⚠️ Warning: Abruptly changing the thermostat settings to maximum cold immediately after loading a large amount of warm food can lead to Compressor freezing. The engine will work for wear, trying to cool a volume exceeding the design volume.
Why does the scale of the mechanical regulator not match the degrees?
The mechanical thermostat is calibrated in conventional units, since it reacts to the expansion of the bellows with gas, and not to a digital signal. The numbers from 1 to 7 (or 0 to max) indicate only the relative cooling intensity, and not the exact temperature in degrees Celsius.
Setting a mechanical temperature controller
Owners of classic models, such as Atlant KSh-250 or two-chamber Atlant 4000 serieshave to rely on intuition and knowledge of symbols. The regulator is usually located inside the refrigerator compartment, in the upper right corner or above the door. The scale can have designations from 1 to 7, from 0 to Max or from Min to Max.
For standard food storage mode, it is recommended to set the switch to the middle position. If the scale has 7 divisions, the optimal value would be 3 or 4. This provides a temperature of about +4...+5°C, which is ideal for dairy products, meat and ready meals. Position 1 or 2 makes the cold less intense, which is important in winter or with low load.
Maximum values (6, 7 or Max) should be used only for a short time. For example, if you need to quickly cool drinks before guests arrive. Constant operation in this mode will lead to the formation of a “fur coat” on the back wall and possible freezing of products to the evaporator.
☑️ Checking the mechanical settings
It is important to take into account seasonality. In the summer, when the room is hot, it is more difficult for the compressor to release heat, so you can increase the mode a little. In winter, on the contrary, it makes sense to reduce the load, especially if the refrigerator is located near a window or in an unheated room (if the model allows it).
Control of the electronic unit and display
More modern models, such as Atlant XM 4423 N or XM 6021, are equipped with a digital display on the outside doors. Here the process of setting the temperature in the Atlant refrigerator becomes more transparent. You see specific numbers and can control each circuit separately.
To change parameters, a button with an image of a thermometer or a snowflake is usually used. Pressing will cause the selected camera's indicator to blink. Use the “+” and “-” buttons to set the desired value. The standard recommendation for the refrigerator compartment is +3...+4°C, for the freezer - minus 18°C.
Electronics often have a child lock function. If the indicators do not respond to pressing, the “Lock” mode may be activated. To remove it, you usually need to (hold) a special button for 3-5 seconds until a signal sounds.
| Value on display | Recommended product | Shelf life (approx.) | Placement area |
|---|---|---|---|
| +2...+4°C | Fresh meat, fish | 1-2 days | Bottom shelf |
| +4...+6°C | Dairy products, eggs | 3-5 days | Middle shelves |
| +6...+8°C | Vegetables, fruits, sauces | 5-7 days | Drawers/Door |
| -18°C and below | Frozen semi-finished products | Up to 12 months | Freezer |
Super freeze mode: when and how to turn it on
The Super Freeze function is a powerful tool that forces the compressor to run continuously for a certain time or until manually canceled. In models with electronics, a separate button with snowflakes or an inscription is provided for this purpose. When activated, the corresponding indicator lights up. Super. When activated, the corresponding indicator lights up.
It is advisable to use this mode when loading a large volume of fresh, non-frozen food into the freezer. Rapid freezing prevents the formation of large ice crystals inside the cells of the product, preserving its structure and taste after defrosting. The mode is also useful if you want to make ice for a party in the shortest possible time.
It is important to remember to turn off the super freeze after completing the task. In mechanical models (Atlant 1700, 1800), this function often needs to be turned off manually, while in digital (Atlant 6021-000) the timer can turn off the mode automatically after 24-48 hours.
⚠️ Attention: Long-term operation in super freezing mode (more than 2-3 days without a break) can lead to overheating of the compressor and a significant increase in electricity bills. Use the function only when necessary.
Optimal values for different food groups
There is no universal temperature for all products, and this creates a dilemma when setting up. However, modern Atlant refrigerators, especially with the system No Frost, ensure uniform distribution of cold, which minimizes differences. However, knowing the storage zones will help you adjust your equipment more accurately.
Dairy products and prepared foods feel best at +4°C. At higher temperatures, bacteria begin to multiply more actively, and at lower temperatures, the milk may freeze at the wall, changing its consistency. It is better to store meat and fish in the coldest zone, usually the bottom shelf above the vegetable drawers, where the temperature is around +2°C.
Vegetables and fruits require a more gentle regime (+6...+8°C) and high humidity. If you set the overall setting too low, the greens in the bottom drawers may freeze and become slimy. If your model has a separate freshness zone (zero chamber), you can put products that require special care there.
Common errors when adjusting
One of the most common mistakes is setting the regulator to maximum immediately after turning on or defrosting. Users think that the cold will accumulate faster this way, but this only creates excess load. The refrigerator will gain temperature faster if you load it with room temperature products gradually, rather than in one gulp.
Another mistake is ignoring the location of the products. If you pack the chamber so tightly that air cannot circulate, the temperature sensor may show incorrect readings. In systems No Frost it is important not to block the ventilation holes on the back wall, otherwise the cold will not flow to the sensor and the compressor will not turn off.
Also, users often forget to check the tightness of the door after changing the settings. If you expose it to extreme cold, the formation of condensation and ice on the seal may increase, which will lead to a leak. Check the condition of the rubber band regularly.
⚠️ Attention: Specifications and location of controls may vary depending on the year of manufacture and the specific modification of the refrigerator. Always check the instructions included with your device, as interfaces can be updated by the manufacturer.
Frequently asked questions (FAQ)
Why does ice freeze in the Atlant refrigerator, even if I did not turn on super freezing?
Most likely, the thermostat is set to maximum value (6-7 or Max), or the defrost sensor is faulty. Also, the reason may be a loosely closed door or a clogged drainage hole, due to which the water does not have time to drain and freezes.
What temperature should be set in the Atlant freezer in the summer?
The optimal value remains -18°C. However, if the room is very hot (above +30°C), the compressor may work overload. In this case, you can temporarily increase the temperature to -15°C if you are not storing food for a long time, or make sure that the refrigerator is located away from heat sources.
What does the flashing temperature indicator on the display mean?
Flashing usually indicates that the temperature in the chamber is higher than the set norm. This happens immediately after switching on, after defrosting, or if you have kept the door open for a long time. If the indicator continues to blink after a day of operation, there may be a freon leak or a thermostat failure.
Is it possible to turn off the door open sound signal?
In most Atlant models, the sound signal is a mandatory safety feature and cannot be turned off by standard means. It stops sounding only after closing the door. In some advanced models, the signal can be temporarily muted by pressing any button on the control panel.
