Correct setting of temperature conditions - this is the foundation for the long service life of your household appliances and a guarantee of product safety. Owners of Belarusian brand equipment often wonder what thermostat value is optimal for Atlant refrigerators. The answer depends on many factors: the time of year, the load on the chambers and even the geographic location of the apartment.
Too low a temperature leads to excessive energy consumption and the formation of an ice crust, and a high temperature leads to damage to the contents. In this article we will analyze the technical nuances of the operation of the compressor and evaporator so that you can set climate mode perfectly.
Modern models are equipped with electronic control, but even in old mechanical devices you can achieve excellent results. It is important to understand that thermostat reacts not to the air temperature in the chamber instantly, but to the state of the evaporator, so changes occur with a delay.
The principle of operation of the thermostat in different models
All refrigerators are divided into two large groups by type controls: mechanical and electronic. In models with mechanical thermostat you see a knob with numbers from 1 to 7 or from Min to Max. It is important to remember here: the number does not indicate degrees Celsius, but the cooling force.
The higher the number on the mechanical handle, the lower temperature inside the chamber. Setting the value to "7" or "Max" causes the compressor to work almost non-stop, which can lead to freezing of the rear wall and excessive energy consumption. On the contrary, position “1” or “Min” puts the unit into a gentle mode.
⚠️ Attention: Never leave the mechanical regulator in the “Max” position for a long time. This is an emergency mode for quick freezing, and not for everyday use.
Electronic control panels, characteristic of the series Atlant XM-4425 or XM-6025, allow you to set exact values in degrees. Here the system itself controls the on and off cycles, based on the readings of internal temperature sensors.
Why do the numbers on the handle not coincide with degrees?
In mechanical thermostats, the scale is calibrated by the manufacturer so that the middle position (usually 3 or 4) corresponded to standard +4...+5°C. Shifting the handle changes the contact threshold, and not directly the temperature of the refrigerant.
Optimal values for the main chamber
The gold standard for storing most products is considered to be the range from +2 to +5 degrees Celsius. It is under these conditions that pathogenic bacteria multiply slowest, preserving the freshness of meat, dairy products and ready-made meals.
If you have a mechanical model, set the regulator to the middle position. Usually this is a number "3" or "4" on a seven-point scale. For electronic models, it is enough to set it to +4°C. This is a universal value suitable for normal conditions operation.
However, it is worth considering the location of the shelves. The temperature in the refrigerator is distributed unevenly:
- 🥩 On the bottom shelf (above the vegetable drawers) it is always the coldest - this is ideal for storing raw meat and fish.
- 🥛 On the middle shelves the temperature is most stable - place dairy products, sausages and ready-made dishes here.
- 🥤 The door shelves are warmest due to frequent opening - this is a place for sauces, drinks and foods with preservatives.
Do not fill the chamber with food to capacity. For proper operation air circulation a cold flow must pass freely between the products. If the shelves are packed tightly, the thermostat may not read the data correctly, and the compressor will work with overload.
Setting up the Atlant freezer
The freezer requires more low temperatures for long-term storage of stocks. The standard value is -18°C. With this mode, most products retain their properties for up to 12 months.
In mechanical models, the freezer is often adjusted using the same handle as the main chamber, or a separate “Super Freeze” switch. In two-compressor models Atlant you can independently configure modes, which is very convenient.
| Storage mode | Temperature | Shelf life (approximate) | Type of products |
|---|---|---|---|
| Short-term | -6°C ... -12°C | Up to 1 month | Semi-finished products, bread |
| Standard | -18°C | Up to 12 months | Meat, fish, vegetables, berries |
| Deep frozen | -24°C and below | Up to 18 months | Long-term storage, preparations |
The Quick Freeze function (often indicated by a snowflake or the letter F) temporarily lowers the temperature to -24°C. Use it only when loading a large volume of fresh food. After freezing (after 12-24 hours), be sure to return the settings to normal mode so as not to damage the compressor.
⚠️ Attention: Long-term operation of the freezer at temperatures below -24°C leads to accelerated wear of the door seals and an increase in electricity bills without any real benefit to the food.
Seasonal adjustment of settings
External temperature significantly affects the operation of refrigeration equipment. In the summer, when the apartment is hot, heat exchange is difficult and the compressor has to work harder. In winter, with heating running or, conversely, with ventilation, conditions change.
In summer, it is recommended to slightly increase cooling. If you have a manual, move the knob one division closer to the maximum (for example, from 3 to 4). Electronic models can be set to +3°C instead of +5°C. This compensates for the heating of the walls from the warm air in the room.
In winter the situation is the opposite. If the room is cool, the default settings may be too much. However, if you single-compressor refrigerator with a No Frost or drip system, a strong reduction in load can lead to improper operation of the valves.
In the off-season, when the heating is not yet (or no longer) working, monitor the humidity. With high humidity and low temperature inside the chamber, condensation may more actively form on the walls, which then freezes.
Features of models with the No Frost system
Technique Atlant with the No Frost (or Low Frost) system requires a special approach. Here, cold air is pumped by fans, which ensures uniform temperature, but creates specific conditions for products.
The main feature is the risk of overdrying. Therefore, in such refrigerators you should not set the minimum possible temperature unless necessary. It is optimal to keep +4...+5°C. Lower values will cause unwrapped food to lose moisture in a matter of hours.
In models with fan cooling it is important to position food correctly:
- 🌬️ Do not block the openings cold air outlet on the back wall.
- 📦 Use containers with lids to prevent moisture from food from settling on the evaporator.
- ❄️ Avoid setting the temperature below +2°C, otherwise vegetables may “burn” from the cold.
Automatic defrosting system in such models is sensitive to thermostat settings. If you set the temperature too low, the defrost cycle may not have time to complete, resulting in ice buildup on the hidden evaporator and noisy fan operation.
Diagnosing problems through temperature settings
Sometimes users turn the thermostat knob in an attempt to fix a problem. This is a mistake. If the refrigerator has stopped freezing or, on the contrary, turns everything into ice, the situation cannot be corrected by adjusting the settings - it requires repair.
Signs when adjusting the temperature does not help:
The compressor hums constantly, but there is no cold. This indicates a freon leak or compressor failure. It is useless to turn the knob - the system is already working at its limit.
A “fur coat” forms in the camera even at minimum settings. Most likely, the defrost sensor has failed or the valve is stuck. In this case, you need to call a technician.
☑️ Check before calling a technician
It is also worth checking the sealing gum. If it allows warm air to pass through, the refrigerator will try to compensate for the heat by wearing out. In this case, even the correct installation of the thermostat will not produce results.
⚠️ Attention: If you hear clicks from the thermostat, but the compressor does not start, there may be a problem with the start relay or the regulator itself. Do not try to repair the electrical part yourself without skills.
Saving energy through proper configuration
The refrigerator is one of the main consumers of energy in the house, as it works around the clock. Correct setting allows you to reduce electricity consumption by up to 15-20% without compromising the quality of storage.
Every extra degree of cold is an additional load on the motor. If you mainly store drinks and foods with a long shelf life, there is no point in setting +2°C. A value of +5°C or even +6°C (for models with fine tuning) will be quite sufficient.
For mechanical models the rule is simple: the lower the number, the more economical. But don't overdo it. If food starts to spoil, saving becomes meaningless. Find a balance in which milk lasts 3-4 days and meat does not freeze.
The effect of defrosting on energy consumption
If the refrigerator requires manual defrosting, a layer of ice 5 mm thick increases energy consumption by 10-15%. Regular defrosting is more economical than constant operation at high speeds.
Remember that aging equipment also makes adjustments. An old refrigerator with a worn seal or dirty heat exchangers in the back will consume more, even if you set the most economical settings.
What to do if the temperature fluctuates?
If you notice that food freezes and thaws, check if the refrigerator is located next to a heat source (stove, radiator). Also, the cause may be a malfunction of the thermostat, which requires replacement.
Is it possible to turn off the refrigerator at night?
It is strictly not recommended. Frequent defrosting and freezing cycles are detrimental to the compressor and food. Modern Atlant models are economical enough to operate around the clock.
Why do different Atlant models have different scales?
The manufacturer uses different types of thermostats (Tam-133, K-59, etc.) depending on the year of manufacture and series. The principle “the higher the number, the colder” remains the same for all mechanical models.
How to check the accuracy of the temperature without a thermometer?
Place a glass of water in the center of the chamber overnight. If a thin crust of ice appears on the surface by morning, the temperature is about 0°C or lower. If the water is warm, the refrigerator does not freeze. Ideally, the water is cold, but without ice.
