Refrigerators of the Belarusian brand Atlant are deservedly popular due to their reliability and ease of operation. However, many owners are faced with a question that is often left unaddressed in the instructions: which number should the temperature regulator be set to? The correct answer to this question directly affects the shelf life of products, energy consumption and the durability of the compressor.
Unlike modern models with electronic control, where the temperature is set with an accuracy of a degree, mechanical refrigerators use a rotary switch with a scale from 1 to 7 (or from Min to Max). The numbers on the regulator do not indicate degrees Celsius, they only indicate the intensity of the compressor. Understanding this principle is the key to correctly setting up your device.
In this article we will look in detail at what value is optimal for everyday use, how the setting changes depending on the time of year and what the extreme positions of the thermostat knob mean. You will learn to balance between energy savings and freezing quality, and also learn how to extend the life of equipment Atlant.
The principle of operation of a mechanical thermostat
The mechanical thermostat installed in most models Atlantis a simple but effective device. Inside the housing there is a sensitive element - a bellows filled with gas or liquid, which reacts to changes in temperature in the fridge compartment. When the temperature rises above a set threshold, the contacts close and the compressor begins to work.
By turning the regulator knob, you change the tension of the spring inside the mechanism. The higher the numberto which you set the pointer, the more compressed the spring is. This means that the compressor will have to work longer and harder to cool the chamber before the contacts open. And vice versa: setting it to the minimum value causes the unit to turn off faster.
It is important to understand that the scale from 1 to 7 is a symbol of cooling power. One corresponds to the minimum cold, and seven corresponds to the maximum. Under normal operating conditions, there is no need to turn the knob to maximum, as this leads to excessive load on the engine and waste of electricity.
⚠️ Attention: Never set the regulator to the maximum value (7 or Max) unless absolutely necessary. Constant operation of the compressor at the limit of its capabilities can lead to its overheating and premature failure.
The stability of the temperature inside the chambers depends not only on the position of the handle, but also on the tightness of the door, the amount of food and the temperature in the room. Mechanics require periodic checking, especially if you notice that food has begun to deteriorate faster or, conversely, freeze.
Optimal position of the regulator for everyday use
For standard operating conditions, when the kitchen is maintained at room temperature and the door does not open too often, engineers Atlant recommend installing the regulator in the middle position. This is usually number 3 or 4 on a seven-step scale. It is in this zone that a balance is achieved between sufficient cooling and economical energy consumption.
When the knob is set to 3-4, the temperature in the main chamber is stably kept in the range from +2 to +5 degrees Celsius, which is an ideal condition for storing most products: dairy products, ready meals, vegetables and fruits. The compressor in this mode operates cyclically, having time to rest between starts.
If you have just placed a large amount of room temperature food in the refrigerator, you can temporarily increase the cooling power. However, after the food has cooled, the regulator should be returned to its normal position. Constant operation at high power does not make sense and is harmful to equipment.
Users often mistakenly believe that the higher the number, the “better” and higher quality cold. This is a misconception. The quality of food storage is determined by temperature stability, and not by its extremely low values. Hypothermia can ruin the structure of some foods, such as tomatoes or herbs.
Seasonal adjustment: winter and summer
The ambient temperature significantly affects the operation of the refrigerator. In summer, when the apartment is hot, heat flow through the walls of the building increases. The compressor takes longer to cool the internal volume. On hot days, it is advisable to move the regulator closer to values 4 or even 5 to compensate for the heating.
In winter, the situation changes. If the refrigerator is in a cool room or the kitchen becomes colder due to heating (paradoxically, in winter houses are often drier and warmer, but there are situations with freezing), the load on the unit drops. In the cold season, it is optimal to switch the knob to 2 or 3. This will be enough to maintain the cold, and the compressor will turn on less often.
There is a common myth that in winter the refrigerator needs to be turned off or set to minimum if it is on an unheated balcony. However, modern models Atlant equipped with a No Frost or drip defrosting system, which require a certain temperature range for correct operation. Too low a room temperature can interfere with the circulation of refrigerant.
It should also be taken into account that in winter we open the refrigerator door more often, letting in warm air, or, conversely, less often if supplies are made in advance. Analyze the behavior of the equipment: if the operation indicator on the rear radiator grille is constantly on or you hear a hum without interruption, reduce the power. If the food is melting, add it.
Deciphering the temperature scale and correspondence table
To make it easier for you to navigate the settings, we have prepared a detailed table that will help compare the position of the regulator knob with the expected effect. Remember that the exact degrees depend on the specific model Atlant, the occupancy of the chambers and the ambient temperature.
| Knob position | Operating mode | Expected effect | Recommended application |
|---|---|---|---|
| 1 (Min) | Minimum cooling | The compressor works little, temperature is about +5...+7°C | Storing a small amount of food, economy mode |
| 3 (Average) | Normal mode | Stable +3...+5°C, standard operating cycle | Daily operation, standard set of products |
| 5 (High) | Intensive cooling | Temperature about +1...+3°C, long compressor operation | Hot summer, full load of products |
| 7 (Max) | Freezing / Turbo | Minimum temperature, compressor runs almost non-stop | Fast freezing of fresh food, emergency cooling |
Use of the mode Max (7) is permissible only at short intervals. For example, you brought 5 kg of meat or berries from the market and want to quickly freeze them in the freezer. In this case, turning on the maximum mode will help reduce the temperature in the freezer faster.
However, keeping the regulator at seven all the time is strictly not recommended. This leads to freezing of the evaporator, the formation of an ice crust on the food and a significant increase in energy bills. After freezing food, be sure to return the knob to position 3 or 4.
What happens if you keep the Max mode for a long time?
Prolonged operation at maximum power leads to the fact that the evaporator becomes overgrown with a “coat” of ice, even in models with No Frost (due to a violation of the defrost cycle), the compressor overheats, and the rubber door seals can quickly lose elasticity due to excessive cold.
Specifics of two-chamber models and freezer chambers
In two-chamber refrigerators Atlant with one compressor, the thermostat usually controls the temperature in the refrigerator compartment, and the freezer compartment is cooled according to the residual principle. This means that by regulating the cold in the upper compartment, you indirectly affect the lower one.
If you set the regulator to minimum (1), it will be warm in the refrigerator compartment, but in the freezer the temperature may rise above the required -18°C. The food will begin to thaw. Therefore, even if you need a little cold from above, do not go below two.
In models with the system No Frost it is more important to ensure proper air circulation. Overloading the chambers with food can block the ventilation holes, and then even the maximum setting of the regulator will not help. Always leave gaps between the food and the back wall.
☑️ Checking the correct settings
Models exist Atlant with two compressors. In them, the temperature in the refrigerator and freezer compartments is adjusted independently. In this case, the regulator in the refrigerator compartment is adjusted according to the rules described above (3-4), and in the freezer compartment it is usually also kept in the middle position if deep freezing is not required.
Diagnosis of problems through the regulator settings
The behavior of the temperature regulator can indicate hidden faults. If, when set to "3", the food in the refrigerator compartment freezes (milk turns to ice, vegetables become soft and watery), this may indicate a freon leak or a malfunction of the thermostat. The system “thinks” that there is a lot of heat, and drives the compressor without stopping.
The opposite situation: the regulator is turned up to 5-6, the compressor hums continuously, but the temperature inside barely reaches +10°C. This is a classic sign of loss of refrigerant or reduced compressor performance. In such cases, it is useless to turn the knob any further - you need to call a technician.
⚠️ Attention: If you notice that the refrigerator has been running for days without turning off, do not try to “save” the situation by frequently switching the regulator. This can finally finish off the electronics or the motor. Disconnect the device from the mains and let it rest.
It is also worth checking the condition of the rubber seal on the door. If it does not fit tightly, warm air constantly flows inside. The regulator will try to compensate for this by increasing the operating time, but will not be able to achieve the desired temperature. A simple replacement of the seal will solve the problem more effectively than any manipulation of the settings.
Energy efficiency and service life of equipment
The correct temperature setting is not only about the safety of food, but also about your wallet. The refrigerator is one of the most energy-consuming appliances in the house, running 24 hours a day. The difference between operation in mode “3” and mode “6” can be up to 20-25% of the electricity consumed per month.
In addition, the gentle operating mode prolongs the life of the compressor - the most expensive component of the refrigerator. Atlant. The compressor life is measured by the number of on and off cycles. The less often it is switched on for long periods “for wear and tear”, the longer the unit as a whole will last.
Do not forget about hygiene. Dust on the condenser (grid at the back or bottom) impairs heat transfer. If the refrigerator does not give off heat well, the regulator will be forced to keep the compressor on longer. Regular cleaning behind the refrigerator helps maintain the declared efficiency.
Following these simple rules will allow your refrigerator to work like new even after 10 years of operation. Do not neglect the manufacturer's recommendations included in the design of the mechanical regulator.
What to do if the regulator knob scrolls or falls off?
If the thermostat knob Atlant scrolls 360 degrees and does not lock the position, most likely the plastic rod itself is broken or pen. In this case, the position of the regulator does not change. It is necessary to remove the handle (often it is simply pulled onto the rod) and inspect the mechanism. If the rod inside the housing is broken, the thermostat will need to be replaced. Before the technician arrives, you can try to fix the handle in the middle position with tape, but this is a temporary solution.
Why does ice form on the back wall in the refrigerator compartment?
The formation of ice ("coat") on the back wall in models with a drip defrosting system is a normal process if The ice melts when the compressor is turned off. However, if there is too much ice, check the position of the adjuster. Perhaps it is set to too high a value (6-7), and the moisture does not have time to drain into the drainage. Try reducing the value to 3.
Is it possible to completely turn off the refrigerator with the regulator?
On most mechanical regulators Atlant position "0" or "Off" means completely turning off the voltage supply to the compressor. The refrigerator stops working, but remains plugged in (the light, if any, is on). To completely cut off the power, it is still better to unplug the cord from the network, especially if you are leaving for a long time.
How does the temperature in the room affect the setting?
The manufacturer indicates the climate class of the refrigerator (usually SN, N, ST). If the room is colder than +10°C or hotter than +32°C, the standard settings may not work correctly. In a very cold room, the refrigerator may simply not turn on, believing that it is already cold inside. In the heat it will work to the limit. In such conditions, adjustment of the regulator is mandatory.
Is it necessary to defrost the refrigerator when changing the settings?
No, you can change the position of the regulator while the refrigerator is running. However, if you change it from minimum to maximum (or vice versa) suddenly, give the system 1-2 hours to stabilize the temperature before assessing the result. Sharp changes in settings are not harmful to the mechanics, but the temperature inside will not change instantly.
