Correct setting of the temperature regime is the foundation for the long service of your refrigeration equipment and guarantees the safety of products. Owners of Belarusian brand equipment often wonder how exactly to regulate the climate inside the chambers in order to avoid freezing meat or souring milk. Two-chamber models Atlant equipped with different types of control, from mechanical thermostats to electronic units, and understanding the principle of their operation will allow you to avoid common mistakes.
Incorrectly set values can lead to the formation of ice, increased energy consumption, or even failure of the compressor due to operation in non-stop. In this article, we will analyze in detail the adjustment algorithms for various series, explain the difference between mechanics and electronics, and also give answers to questions that users have during operation.
Before proceeding with the adjustment, it is important to understand that optimal storage conditions depend not only on the device settings, but also on the external temperature in the room, the frequency of door openings and the volume of loaded products. Thermostat or the electronic sensor reads information from the evaporator, but it takes time to stabilize the readings after each change in parameters.
Differences in control systems in Atlant models
All two-chamber refrigerators from this manufacturer can be divided into two large groups according to the type of control interface. The first and most common group are models with a mechanical regulator. In them, the temperature is set by turning the knob with divisions from 1 to 7 (or from Min to Max), where the number does not indicate degrees Celsius, but the intensity of the compressor.
The second type is electronically controlled devices, where a display is located on the front panel of the case or inside the refrigerator compartment. Here the user sees the exact values in degrees and can adjust modes with an accuracy of one division. Such systems are often equipped with a function Fast Freeze (fast freezing) and open door indication.
It is important to consider that in electronic models it is often implemented separate zone control. You can independently change the climate in the upper compartment and freezer compartment, which is impossible to do in simple mechanical versions, where one thermostat controls the overall cooling cycle.
Setting a mechanical thermostat
In classic models such as series 400, 450 or 600, adjustment is carried out using a rotary switch located inside the refrigerator compartment (usually at the top right) or on the lampshade. The scale of divisions is not a linear temperature scale, but represents a gradation of cooling power.
The factory setting is usually set to 3 or 4. This is the optimal mode for everyday use with a standard load of food. If you turn the knob towards higher values, the compressor will work longer and more often, lowering the temperature in all chambers.
- 🌡️ Position “1” or “Min” - minimum cooling, the compressor turns on rarely, the temperature in the refrigerator compartment can reach +8...+10°C.
- ❄️ Position "3-4" is the recommended standard mode, providing +2...+5°C in the main compartment and -18°C in the freezer.
- 🧊 Position "6-7" or "Max" is the maximum power mode, used for quick freezing of large volumes of food or at very high room temperatures.
⚠️ Attention: Long operating a mechanical thermostat in position “7” (Max) can lead to freezing of the evaporator and an increase in the load on the motor-compressor, which reduces the service life of the equipment.
When changing the position of the handle, do not expect instant results. Thermostat it takes 2 to 4 hours to stabilize the climate inside the chambers and enter a new operating cycle. Frequent twisting of the handle back and forth disorients the control system.
Temperature adjustment in electronic models
Modern two-chamber refrigerators Atlant with the No Frost system and electronic control allow you to set precise temperature values. The control panel can be located on the outside door or inside the refrigerator compartment. To change settings, touch buttons or a combination of mechanical buttons are usually used.
To change settings, you often need to press and hold the setting button (indicated by a thermometer symbol or letter E) for 3-5 seconds until the blinking indicators appear. After this, use the “Up” and “Down” buttons to select the desired value for each camera separately.
| Camera | Recommended t°C | Acceptable range | Note |
|---|---|---|---|
| Refrigeration | +3°C | from +2°C to +6°C | Optimal for milk and ready meals |
| Frozen | -18°C | from -15°C to -24°C | Standard for long-term storage |
| Freshness zone | 0°C | from -1°C to +2°C | If there is a separate compartment |
Some models have an intelligent mode, when the device itself selects the operation of the compressor depending on the frequency of door openings. However, even in such systems, manual adjustment is possible and sometimes necessary, for example, in the summer or when the freezer is fully loaded.
What does the flashing indicator on the display mean?
Flashing usually signals an alarm. If the temperature is flashing, it means that the current readings inside the chamber differ from the set values by more than 2-3 degrees. This often happens after defrosting or loading warm food. If the lock symbol is flashing, the child lock of the control panel is activated.
Seasonal characteristics and external factors
The ambient temperature has a direct impact on the operation of the refrigeration unit. In the summer, when the kitchen is hot, heat transfer is difficult and the compressor takes longer to dissipate heat through the condenser (the grill at the back). In winter, the situation may be the opposite if the refrigerator is located near a window or in an unheated room.
In summer, if you notice that the food in the refrigerator compartment has become warmer than usual (+7...+8°C), it makes sense to shift the regulator one notch towards stronger cooling (for example, from 3 to 4). You should also check whether the capacitor is overheating and whether there is a gap between the back wall of the device and the furniture.
In winter, when the room temperature is below +16°C, some older models may not work correctly or may not turn on at all, since the thermostat “does not have enough” heat to open the contacts. Modern models Atlant often use a control system that allows operation at low temperatures, but it is better to clarify this in the data sheet of the specific series.
Super Freeze mode and its effect
The quick freezing function (indicated by a snowflake, asterisk or inscription Fast Freeze) is intended for freezing a large number of fresh products without defrosting those already in the chamber stocks. When this mode is activated, the compressor runs continuously, ignoring the thermostat readings.
This mode should be used with caution. In mechanical models, to turn on “super freezing”, turn the thermostat knob all the way to the right (to number 7). In electronic models, just press the corresponding button. However, leaving the refrigerator in this mode for longer than 24 hours is strictly not recommended.
- 🕒 Duration - turn on the mode 3-4 hours before loading food and turn it off a day after.
- 🔌 Automatic shutdown - in electronic models, the timer will turn off the mode itself after 24-48 hours.
- 📉 Energy consumption - in this mode, electricity consumption increases by 1.5-2 times.
⚠️ Attention: If you forget to turn off the maximum freezing mode, hypothermia may occur in the refrigerator compartment, and food (especially vegetables and drinks in glass) may spoil or burst.
Typical errors and problem diagnosis
Often users are faced with a situation where it seemed If a correctly set temperature does not give the expected result. One common mistake is placing hot or warm foods. This causes a temperature jump, sensors detect the change, and the compressor begins to wear out, trying to compensate for the heat.
Another problem is a violation of the tightness of the door seals. If the elastic does not fit tightly, warm, moist air constantly enters. In this case, even setting the regulator to maximum will not help: a “coat” of ice will grow on the walls, and the temperature in the chamber will be higher than normal.
☑️ Check before calling a technician
It is also worth checking the location of the products. If you completely fill the shelves to the ceiling and block the vents (in No Frost) or the cold air outlet (in drip), circulation will be disrupted. As a result, in one corner it will be warm, and in the other everything will freeze.
FAQ: Frequently asked questions
What number should be set on the Atlant thermostat in the summer?
In the summer, when the room temperature is high, it is recommended to set the regulator to medium values (3 or 4). If this is not enough and the food spoils, you can temporarily switch to 5, but make sure that ice does not form in the refrigerator compartment.
Why is it -10°C in the freezer, although it is set to -18°C?
There may be several reasons: the door is not closed tightly, a large amount of warm food is loaded, the condenser at the back of the refrigerator is dirty, or there is a leak. Freon. If the temperature is not restored 24 hours after adjusting the settings, diagnostics are necessary.
Is it possible to leave the refrigerator at minimum (1) for a long time?
You can leave it at minimum if the room is very cold (for example, at the dacha in winter) or if you store products there that do not require strong cooling (for example, some types of vegetables or drinks). However, for standard storage of meat and dairy, the temperature will be too high, which will speed up spoilage.
What to do if the red temperature light comes on?
The red indicator indicates an increase in temperature above the safe norm. Check if the door is tightly closed. If you just turned on the refrigerator or loaded a lot of food, the light will go off on its own after a few hours. If it lights up constantly, check the settings and operation of the compressor.
