Refrigerators Pozis are deservedly popular due to their reliability and affordable price, however, many owners encounter difficulties during the initial setting of climate parameters. Proper temperature control is not just a matter of comfort, but also guarantees the safety of food and the longevity of the compressor. Errors at this stage can lead to excessive consumption of electricity or damage to the contents of the chambers.
In this article we will analyze in detail the mechanical and electronic methods of climate control in various models, from classic two-chamber units to modern systems with technology No Frost. You'll learn how to interpret indicator readings, what the numbers on a mechanical thermostat mean, and why it's important to take seasonal environmental changes into account when setting up.
Before you take any action, you need to determine the type of control your device will have. This is a fundamental point, since the configuration algorithms are fundamentally different. If you confuse mechanics with electronics, you may not only not achieve the result, but also throw off the factory calibrations.
Determining the type of thermostat in your refrigerator
The first step to proper setup is visual identification of the control system. In the model range Pozis there are two main types of interfaces: mechanical and electronic. Mechanical control is typical for more affordable and classic models, where adjustment is carried out by turning a round knob.
Electronic control, as a rule, is located on the outer door or inside the upper part of the refrigerator compartment and is a display with touch or push-button switches. Digital thermostat allows you to set exact values in degrees Celsius, while mechanics operate with conventional units of power cooling.
If on the inner wall of the chamber you see a round disk with numbers from 1 to 7 (or from Min to Max) and the inscription “Thermostat”, this is a mechanical system. If there is a luminous display with “Mode”, “Temp” or “+/-” buttons, then we are talking about electronic system control.
⚠️ Attention: An attempt to disassemble a mechanical thermostat for “fine tuning” inside the housing will lead to depressurization of the bellows and leakage of freon. Repair in this case will require calling a technician and refilling with refrigerant.Setting a mechanical thermostat
Mechanical thermostats, often labeled as TAM-133 or analogues, operate on the opening principle electrical circuit when a certain temperature is reached. The adjustment is made by changing the compression force of the spring inside the device. The user sees only a scale with numbers, where each division corresponds to a certain temperature range.
To set the optimal mode, you need to turn the knob to the desired position. Typically the scale is graduated from 1 to 7, with one being the minimum cooling (warmest temperature) and seven being the maximum power (lowest temperature). Some models have a “0” or “Off” position, which completely turns off the compressor.
- ❄️ Position 1-2: Maintains a temperature of about +6...+8°C, suitable for storing vegetables and fruits in the cool season.
- ❄️ Position 3-4: Optimal mode for everyday use, providing +3...+5°C in the main chamber.
- ❄️ Position 5-7: Intensive cooling mode or "Super Freeze", the temperature can drop to 0...+2°C, which is dangerous for some products.
It is important to understand that the numbers on pen are not degrees. These are power symbols. The actual temperature inside the chamber also depends on the amount of food, how often the door is opened and the room temperature. Therefore, you cannot rely solely on the number on the handle - control with a thermometer is necessary.
☑️ Checking the mechanical settings
Done: 0 / 5If you set the knob to the middle value, but the products in the upper part of the chamber they begin to thaw, and at the bottom they freeze; this may indicate a malfunction of the thermostat or a freon leak, and not an incorrect setting. In such cases, simply adjusting the knob will not help.
Control of the electronic panel and display
Modern models Pozis, especially the series Smart or Agidel with electronics, offer more precise control. Here you set a specific target temperature. Control can be carried out through a panel on the door or through a hidden interface inside the refrigerator compartment.
A button
ModeorTempis usually used to change parameters. Pressing activates the blinking of the refrigerator compartment indicator, after which the+and-(orUp/Down) buttons are used to set the desired value. After a few seconds of inactivity, the settings are saved automatically.
Mode Temperature range Recommended use Eco +5...+7°C Long-term storage, energy saving Standard +3...+5°C Daily operation Intensive 0...+2°C Quick cooling of drinks or large volumes of food The function Super Freeze (Super Freeze) deserves special attention. When activated, the compressor operates continuously, ignoring the readings of temperature sensors, until you manually turn off the mode or the timer expires (usually 24-48 hours).
⚠️ Attention: Do not leave the “Super Freeze” mode turned on in the refrigerator compartment for more than a day. This will lead to freezing of vegetables and damage to plastic containers due to extremely low temperatures.What to do if the display goes out?
If the screen does not respond to touches, try holding down the "+" and "-" buttons at the same time for 5 seconds. In some models, this unlocks the control panel, which could be locked from accidental presses (Child Lock function).
Adjusting the temperature in the freezer
In two-compartment refrigerators Pozis the freezer often has its own control circuit, especially in systems No Frost. However, in classic models with one compressor and one cooling zone, the temperature in the freezer depends on the settings of the main thermostat.
If you have a model with a separate adjustment knob in the freezer (rare, but found in older models), the principle is the same: the higher the number, the lower the temperature. For high-quality freezing of meat and fish, it is necessary to ensure a temperature no higher than -18°C.
When using the mode No Frost it is important not to clog the air ducts with food. Cold air should circulate freely. If you have fully loaded the freezer with fresh meat, it makes sense to temporarily turn on the fast freezing mode to preserve the fiber structure of the product.
- 🥩 -18°C and below: Ideal for long-term storage of meat, poultry and fish (up to 12 months).
- 🍦 -14...-16°C: Permissible for storing ice cream and semi-finished products that will be used within a month.
- 🧊 -6...-10°C: Short-term storage mode, for example, for defrosting or cooling ready-made frozen products.
It is worth noting that in single-compressor systems, when the thermostat is set to minimum (maximum cold), it may become too cold in the refrigerator compartment, and in the freezer the temperature will drop to -24°C or lower. This increases the load on the compressor.
The influence of external temperature and seasonal adjustment
The environment has a direct impact on the operation of the refrigeration unit. In summer, when the temperature in the kitchen reaches +25...+30°C, heat inflows increase and the compressor takes more time to achieve the set parameters. In winter, the situation is the opposite.
Many users mistakenly believe that in winter the refrigerator needs to be “heated” or moved to a warmer place. In fact, if in the room where it is located Pozis, the temperature drops below +16°C (for climate class SN) or +10°C (for class N), the thermostat may simply not turn on the compressor, considering that it is already cold enough inside.
📊 At what temperature does your refrigerator most often operate in your kitchen?+15...+20°C (cool)+20...+25°C (comfortable)+25...+30°C (hot)Above +30°C (very hot)In the summer, it is recommended to slightly increase the cooling (move the knob towards larger numbers by 0.5-1 division) to compensate for the heating of the walls from hot air. In winter, on the contrary, you can loosen the mode a little, since the natural cold of the room helps the unit.
It is critically important to comply with the climate class specified in the passport. If you operate a refrigerator in an unheated country house in winter, standard temperature control will not help - the device may stop working correctly without installing a special winter kit or heating the thermostat zone.
⚠️ Attention: Installing the refrigerator next to a heating radiator or in direct sunlight makes any temperature adjustment useless. The unit will work for wear, trying to compensate for external heating.Diagnosis of problems after adjustment
After you have changed the settings, you need to wait time for the temperature to stabilize. The thermostat is an inertial device. Evaluation of the effectiveness of new settings is possible no earlier than after 6-8 hours, and complete stabilization takes up to 24 hours.
If after adjustment you observe the following symptoms, it means that the problem is not in the settings, but in technical serviceability:
- A “snow coat” or ice crust forms on the back wall of the refrigerator compartment even with minimal settings.
- Foods in the refrigerator freeze when the knob is set to "2" or "3".
- The compressor works non-stop for days, trying to reach the temperature that the display shows (or that you expect).
In the first case, the door is likely skewed or the seal that allows humid air. In the second, sticking of the thermostat contacts or loss of the properties of the thermal insulating tube. In the third, there is a refrigerant leak or a malfunction of the thermostat itself.
Sometimes a complete reset of the settings helps. For electronic models, this is done by disconnecting from the network for 10-15 minutes. For mechanical ones - turn the knob to position "0", wait 5 minutes and return to operating mode. This allows you to “defrost” a possible ice jam in the capillary tube of the thermostat.
Frequent errors when operating the thermostat
Inexperienced users often make mistakes that nullify all adjustment efforts. One of the most common is setting the maximum cold immediately after loading warm products. This creates a peak load.
Another mistake is frequently changing settings. You shouldn’t turn the knob every hour to check if it’s getting colder. The thermostat should complete the cycle. It is also a mistake to place hot pots in the chamber, thinking that “powerful cold” will cool everything down - this will only spoil neighboring products and disrupt the sensor settings.
Remember that The accuracy of a mechanical thermostat is ±2°Ctherefore, small temperature fluctuations are normal and do not require intervention. Electronics are more accurate, but it also depends on the correct placement of sensors.
Why does the Pozis refrigerator not maintain the temperature even after adjustment?
If the adjustment does not help, check the tightness of the door. Often the problem lies in a skewed door or a dirty seal through which the cold escapes. Also, the reason may be freezing of the evaporator, which requires complete defrosting within 24 hours.
Is it possible to use an external thermometer for calibration?
Yes, this is the most reliable way. Place a household thermometer in a glass of water on the middle shelf. After 6-8 hours, compare the readings with those set on the thermostat. If the difference is large, the mechanical handle can be adjusted by trial, and the electronic handle can be reprogrammed in the service menu (if the model allows it).
What does the flashing temperature indicator on the display mean?
Flashing usually signals a high temperature alarm. This means that the inside of the camera is warmer than specified in the settings. Check that the door is closed tightly, that you have not loaded a lot of warm food, and that the compressor is running. If the blinking does not stop after a day, call a specialist.
How to convert degrees Fahrenheit to Celsius on the display?
In some models Pozis with expored origin or specific firmware, the scale may go astray. Typically, switching is done by long (5-7 seconds) pressing the temperature setting button or a combination of buttons. It is better to find the exact combination for your model in the instructions, since it is unique for each series of control boards.
Do you need to change the settings when switching to summer/winter mode?
Yes, seasonal adjustment is desirable. In summer, at high ambient temperatures, it is worth increasing the cooling by 1 notch. In winter, if the room is cool, you can relax the mode to prevent excessive freezing of food and reduce the load on the unit.
