Correct setting of the temperature regime is the foundation for the long service of household refrigeration equipment and the safety of your products. The brand's two-chamber models Atlant, produced at the Minsk plant, have proven themselves to be reliable units, but they require competent initial setup. Many users make the mistake of relying only on intuition or setting the controls to extreme positions immediately after purchase.
Incorrect settings of the thermostat or electronic control unit can lead to rapid spoilage of food in the refrigerator compartment or, conversely, to freezing of vegetables and fruits. Moreover, constant operation of the compressor at maximum power due to incorrectly set parameters significantly reduces the life of the motor. In this article, we will analyze in detail how to set the optimal values for various modifications of equipment.
Principles of operation of the thermostat in Atlant refrigerators
Most models of refrigerators Atlant with mechanical control use a thermostat that responds to changes in temperature inside the refrigerator compartment. This device opens the electrical circuit when the specified cold is reached, and closes it when the air heats up above the set threshold. Understanding this cycle is important in order not to expect an instant result after turning the knob.
The numbers on the scale (usually from 1 to 7 or from Min to Max) indicate cooling intensityrather than specific degrees. Unit "1" means minimum cooling (warmest temperature), and "7" or "Max" - maximum compressor power.
In models with electronic control, where the displayis located on the door, the situation is different. Here you set a specific target temperature that the intelligent control unit should maintain. The electronics itself regulate the operating time of the compressor and fans in order to achieve the set parameters with high accuracy.
Optimal temperature conditions for different chambers
To ensure food safety and compliance with sanitary standards, the temperature in the refrigerator compartment must be maintained in the range from +2 to +5 degrees Celsius. It is under these conditions that pathogenic microorganisms multiply slowest. Setting a value below +2 degrees is not recommended, as this can lead to freezing of fresh vegetables, fruits and dairy products.
In the freezer compartment of two-compartment refrigerators Atlant the temperature should not be higher than -18 degrees Celsius. This standard is accepted internationally for long-term storage of meat, fish and semi-finished products. With this mode, products can be stored for up to 12 months without loss of taste and tissue structure.
There is a misconception that the colder the better. However, setting the freezer temperature to -24 degrees or lower only makes sense in "Super Freeze" mode for quickly cooling a large volume of fresh food. Constant operation in this mode leads to increased energy consumption and accelerated wear of the compressor.
Instructions: how to set the temperature mechanically
If your refrigerator is equipped with a rotary handle inside the refrigerator compartment, you are dealing with mechanical control. Most often, the scale has divisions from 1 to 7. The manufacturer Atlant recommends setting the regulator to the middle position for normal operating conditions. This usually corresponds to divisions 3 or 4.
You don't need tools to change the settings. Simply turn the handle in the desired direction. However, this should be done smoothly, without sudden jerks, so as not to damage the thermostat mechanism. After turning the knob, changes will not occur instantly, but within several hours of operation of the unit.
Here are the basic recommendations for choosing a division on the scale depending on the conditions:
- 🌡️ Division 1-2: Use in the summer in very hot rooms or when the refrigerator is almost empty.
- 🌡️ Division 3-4: Standard mode for everyday use at room temperature.
- 🌡️ Division 5-6: In winter in unheated rooms or when the chamber is fully loaded with food.
- 🌡️ Division 7 (Max): Only for fast freezing mode or if the seal is faulty (temporarily).
☑️ Checking the correct settings
⚠️ Attention: Never leave the mechanical thermostat control in position “7” (Max) on a permanent basis. In this mode, the compressor operates almost without stopping, which is guaranteed to lead to its overheating and failure in a short time.
Setting up the electronic control unit
In more modern models Atlant (XM series, CM with index F and others) control carried out through a panel on the door. Here the setup process is more transparent, since you can see the digital values. To enter the setting mode, you often need to press and hold the temperature adjustment button for 3-5 seconds until the numbers begin to flash.
Using the Up and Down arrow buttons, select the desired value. For the refrigeration chamber, +3°C or +4°Cwill be optimal. For the freezer, the standard is -18°C. After selecting a value, you usually need to not press anything for 5-10 seconds so that the control unit saves the new parameters.
Some models allow you to configure additional functions that affect the temperature:
- ❄️ Super Freeze (Super Freeze): Forcibly lowers the temperature in the freezer to a minimum.
- 🍺 Refrigerator (Cooling): a similar mode for the refrigerator compartment (cooling drinks).
- 🔒 Lock (Lock): prevents children from accidentally changing the settings.
What to do if the display does not respond?
If nothing happens when you press the buttons on the display, the control panel lock may be activated. Find the button with the image of a lock and hold it for 3-5 seconds until a characteristic sound signal appears or the indicator flashes.
The influence of external factors on the temperature regime
Setting the temperature is not a one-time action, but a process that depends on the environment. The refrigerator Atlant, like any other equipment, is sensitive to room temperature. If the room is hot (above +25°C), heat exchange is disrupted and the unit has to work harder.
In winter, the situation may be the opposite. If the refrigerator is located near a window or in an unheated kitchen, where the temperature drops below +10°C, the compressor may not turn on at all, since the thermostat “thinks” that it is already cold enough inside. This is especially true for models with one compressor.
It is also worth considering the location of the equipment:
- ☀️ Direct sunlight heats the housing, forcing the thermostat to work in an enhanced mode.
- 🍳 Proximity to the stove or battery creates local heating zones, distorting the readings sensors.
- 🌬️ The lack of a gap between the back wall and the wall interferes with the cooling of the condenser.
⚠️ Attention: Technical characteristics of refrigerators may vary depending on the climate class. Make sure that the operating conditions of your model correspond to the climate class specified in the device passport (usually SN, N, ST).
Table of correspondence between settings and temperatures
For the convenience of users, below is a table that will help you navigate the settings of mechanical thermostats. Remember that these values are averaged and may vary slightly depending on the specific model Atlant and the degree of its load.
| Position of the regulator | Approximate t° in the refrigerator compartment | Compressor operating mode | Recommendation for use |
|---|---|---|---|
| 1 (Min) | +6..+8°C | Short cycles, long pauses | Summer, small number of products |
| 3 | +4..+5°C | Normal operating cycle | Standard mode (basic) |
| 5 | +2..+3°C | Long operation | Winter, full load |
| 7 (Max) | 0..+1°C | Almost non-stop | Only for quick freezing |
Typical errors and ways to eliminate them
One of the most common mistakes is an attempt to “speed up” the cooling of food by setting the maximum mode immediately after loading warm food. Not only will this not help, but it will also create an excessive load on the system. Warm foods must first be cooled to room temperature before being placed in the chamber.
Another mistake is ignoring the sounds of the operating unit. If you hear the motor humming continuously without stopping for hours, check the settings. Perhaps the regulator is accidentally moved to the “Max” position, or the door is not closed tightly, and cold air is constantly escaping.
What to do if the temperature does not correspond to the settings?
- Check the tightness of the rubber seals around the perimeter of the door.
- Make sure that the products do not block the air circulation channels inside chambers.
- Defrost the refrigerator completely (if it is not a No Frost system) and check the operation again.
⚠️ Attention: If, when setting average values, the food in the refrigerator compartment freezes and melts in the freezer, this may not indicate an incorrect setting, but a freon leak or a malfunction of the thermostat. In this case, diagnostics by a specialist is necessary.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Atlant refrigerator?
This is a normal process for a drip defrosting system. Moisture condenses on the coldest part (the back wall), freezes, and then, when the compressor turns off, melts and flows into the drain hole. If there is too much ice, check if the drainage hole is clogged, and make sure that the temperature is not set to the minimum (1-2 steps), due to which the wall does not have time to thaw.
What temperature should you set in the summer, if the apartment is hot?
In the hot season (when the room is above +25°C), it is recommended to switch the mechanical thermostat to a higher temperature gentle mode (closer to 2-3) to give the compressor a chance to rest. However, if food begins to spoil, it is better to ventilate the room more often or use a fan than to leave the refrigerator at minimum cooling.
What does a flashing indicator on the display mean?
Flashing numbers or a special indicator (often red or in the form of a bell) on electronic models Atlant usually signals an increase in temperature in the camera is above the permissible limit. This may be a consequence of opening the door for a long time, loading a large volume of warm food, or a malfunction of the cooling system.
Is it possible to use the Atlant refrigerator at temperatures below +10°C?
Most household refrigerators are not designed to operate in unheated rooms at temperatures below +10°C (climatic class N). The oil in the compressor thickens, and the unit may not start or quickly fail. There are models with an extended climate class (SN), but it is better to clarify their operation in the cold in the instructions for a specific modification.
