Refrigeration equipment of the brand Pozis Paracels is deservedly popular due to its reliability and ability to maintain a stable microclimate for storing medicines and products. However, for the equipment to work correctly, it is necessary to correctly set the temperature, which may vary depending on the contents of the chambers. Many users encounter difficulties during the initial setup, since the digital symbols on the thermostat are not always intuitive.
Incorrectly set parameters can lead to damage to perishable goods or, conversely, to their freezing, which is unacceptable for many types of pharmaceutical products. In this article we will analyze in detail the algorithm of actions, consider the features of the thermostat and answer frequently asked questions that arise when operating units of this series. Proper adjustment will extend the life of the compressor and ensure ideal storage conditions.
The principle of operation of the thermostat and interpretation of the values
Temperature control in refrigerators Pozis Paracels is carried out using a mechanical or electronic thermostat located inside the main chamber or on an external control panel. Most models use a mechanical rotary switch with a scale where the numbers indicate not degrees Celsius, but the intensity of the compressor. Understanding this logic is key to proper operation of the device.
The thermostat scale is usually graduated from minimum to maximum, often from 1 to 7 or from "Min" to "Max". It is important to remember the main rule: the higher the number, the lower temperature inside the chamber, that is, the more intensively the refrigeration unit works. If the regulator is set to the minimum value, the compressor will turn on less often, maintaining a less cold climate, which may not be enough for long-term storage.
The middle position of the handle, as a rule, corresponds to the optimal operating mode, in which the temperature in the main chamber is kept within +2...+5°C. This is the standard range recommended for most foods and medications. Changing the position of the regulator even by one division can significantly affect the internal climate, so adjustments should be carried out smoothly.
⚠️ Attention: Do not try to sharply turn the thermostat knob across the entire scale. Mechanical contacts inside the device can be damaged if handled roughly, resulting in sticking or failure of the control system.
Electronic models can be equipped with a digital display where the temperature is displayed directly in degrees Celsius. In such devices, settings are made using the “+” and “-” buttons, which simplifies control, but requires care so as not to accidentally disable the set mode. Always check the display readings with the actual state of the products.
Preparing for setting the temperature mode
Before you begin active adjustment, you must make sure that the refrigerator is correctly installed and prepared for operation. An unprepared device may show incorrect data, and configuration under such conditions will be incorrect. First, check that the unit is in an upright position and does not touch walls or furniture, which will ensure proper air circulation around the condenser.
If you have just connected the refrigerator to the power supply, do not rush to immediately set the operating parameters. Let the equipment operate in standard mode for at least a few hours so that the temperature background stabilizes. Loading the chamber with food also affects the cooling rate, so an empty refrigerator will gain cold faster, but it will also retain heat worse.
☑️ Preparing the refrigerator for setup
Make sure that the doors close tightly and the seals are not damaged. Chamber tightness is the foundation for maintaining the set temperature. If the cold escapes through a loose rubber band, the thermostat will constantly keep the compressor on, trying to compensate for heat inflows, which will lead to excessive energy consumption and equipment wear.
It is also worth checking whether the ventilation holes inside the chamber are not blocked by products. The circulation of cold air must be free, otherwise the temperature sensor may read incorrect data, being in a zone of local hypothermia or, conversely, in a heat pocket.
Step-by-step instructions: how to set the temperature
The setting process depends on the type of control of your model Pozis Paracels. For mechanical thermostats, the algorithm is simple, but requires consistency. First, locate the control knob, which is usually located at the top of the refrigerator compartment or on the ceiling of the compartment. Carefully turn it to the middle position, which is often marked with a mark or number in the middle of the scale.
After setting the knob to the desired position, you must wait. Thermodynamic processes are inertial, and it may take from 6 to 12 hours to stabilize the temperature throughout the entire volume of the chamber. Only after this time can you draw conclusions about whether it is cold enough or, conversely, too frosty.
If after the stabilization period you find that the food is freezing, turn the knob towards lower values (to number 1 or "Min"). If the cooling is insufficient and the food spoils quickly, increase the power by turning the knob towards larger numbers. Each change again takes time to stabilize, so do not turn the knob too often.
In models with electronic control the procedure looks different. Press the Set button (often labeled "Set" or a thermometer icon) and hold it for a few seconds until the numbers on the display begin to flash. Use the navigation buttons to select the desired value, then confirm the selection or simply wait until the display stops flashing.
⚠️ Attention: When setting up electronic models, avoid touching the buttons with wet hands. Moisture that gets into the gaps of the button panel can cause a short circuit or oxidation of the contacts.
Optimal values for different products and medicines
There is no universal temperature that is ideal for the entire contents of the refrigerator. Different groups of goods require different storage conditions, and when filling the chamber Pozis Paracels this must be taken into account. The main chamber usually supports a range from 0 to +10°C, and your task is to find a middle ground or use zoning.
Meat and fish products, as well as ready-made meals, are best stored at temperatures from 0 to +3°C. This prevents the growth of bacteria and maintains freshness. Dairy products and eggs feel comfortable at +3...+5°C. Vegetables and fruits, on the contrary, do not like extreme cold and can lose their taste or freeze at temperatures below +4°C, so it is better to place them in special containers or closer to the door.
Require special attention pharmaceuticals. Many vaccines, insulins and serums require strict temperature control, often within +2...+8°C. For such purposes, refrigerators Pozis Paracels are ideal, but monitoring must be constant. The use of a separate thermometer-hygrometer inside the chamber is a mandatory requirement for pharmacies and medical institutions.
Below is a table of recommended temperature conditions for various product categories:
| Product category | Recommended temperature (°C) | Shelf life (approx.) | Placement area |
|---|---|---|---|
| Fresh meat and fish | 0... +2 | 1-2 days | Bottom shelf / Freshness area |
| Dairy products | +2... +5 | 3-5 days | Middle shelves |
| Ready meals | +2... +5 | 1-2 days | Middle shelves |
| Vegetables and fruits | +4... +8 | 3-7 days | Bottom drawers |
| Medicines (general) | +2... +8 | According to instructions | Middle shelves (not against the wall!) |
Features of operation in the freezer compartment
If your refrigerator Pozis Paracels is equipped with a freezer compartment, its setting is also critical for the quality of freezing. The freezer temperature should be -18°C or lower. On mechanical thermostats, this usually corresponds to the maximum scale value or the special “Super Freeze” mode.
When loading a large amount of fresh food for freezing, it is recommended to temporarily enable the fast freezing mode. This forces the compressor to work continuously, quickly reducing the temperature of new products to the required values, which preserves their structure and beneficial properties. However, you should not keep this mode on all the time.
What happens during long-term operation in Super Freeze mode?
Long-term operation of the compressor in maximum power mode without breaks can lead to overheating of the motor windings and a reduction in the life of the refrigerator. Use this mode only when you need to quickly freeze large volumes, turning it off after 24 hours.
Watch for ice formation. If the layer of snow on the walls of the freezer exceeds 5-7 mm, this impairs heat transfer. In this case, the compressor has to work longer to maintain the set temperature, which leads to increased energy consumption. Regular defrosting (unless the model is No Frost) helps maintain efficiency.
It is important not to overload the freezer compartment, leaving space for cold air to circulate. If the chamber is jam-packed, the cold will not be able to be evenly distributed, and above-zero temperatures may remain in the center while everything at the walls is frozen into stone.
Diagnosis of problems: why the temperature does not hold
Sometimes users are faced with a situation where the seemingly correctly set temperature is not achieved. If you notice that the chamber is warmer or colder than it should be, and adjusting the thermostat does not help, it is worth conducting an initial diagnosis. One of the common reasons is a violation of the tightness of the door seal.
Check whether the rubber fits tightly around the entire perimeter. The test with a sheet of paper is simple and effective: hold the sheet of paper in a door and try to pull it out. If the sheet is pulled out without effort, it means that the seal does not fit in this place, and the cold goes away. The cause may also be dust-clogged ventilation holes on the rear wall of the unit.
Another possible reason is a malfunction of the thermostat itself or a refrigerant leak. If the compressor works almost non-stop, but there is no cold, or, conversely, is silent when it should be cold, it is probably required refrigerator repair. In such cases, self-tuning will no longer help.
⚠️ Attention: Do not try to open the cooling system or replace the thermostat yourself, unless you have the appropriate qualifications and equipment. This can lead to the final failure of the equipment and loss of warranty.
It is also worth considering external factors. If the refrigerator is placed next to a radiator, stove, or in direct sunlight, it will be extremely difficult for the system to maintain a low temperature. In such conditions, even the maximum operating power may not give the desired result.
Frequently asked questions (FAQ)
What should you do if the refrigerator is too cold, even at the minimum setting?
If even at the minimum setting (number 1) food freezes, this may indicate a malfunction of the thermostat, which does not opens the circuit, or there is a problem with the sensor. Also check to see if the temperature sensor is too close to the back wall, where it is coldest. Try moving the sensor or products further away from the back wall. If the problem persists, the thermostat needs to be replaced.
How often should you check the temperature in the Pozis Paracels refrigerator?
It is recommended to check the temperature at least once a month, especially if you store medicines or a large number of perishable foods. Seasonal changes in room temperature (hotter in summer, colder in winter) may require slight adjustments to the position of the thermostat knob to compensate.
Can an external thermometer be used for calibration?
Yes, using an independent thermometer is the most reliable way to control. Built-in indicators (if any) or divisions on the handle are conditional. Place the thermometer in a glass of water on the middle shelf overnight to get an accurate average temperature in the chamber.
Does the amount of food affect the temperature setting?
A full refrigerator keeps the temperature more stable, as the food accumulates cold. In an empty refrigerator, when the door is opened, the temperature rises sharply, and the compressor takes more time to restore mode. Therefore, with a small load, a slightly more intensive operating mode may be required, but be careful not to overcool the contents.
Why does it take a long time for the temperature to be restored after defrosting?
After defrosting, the walls of the chamber and the food are at room temperature. The compressor takes time (usually 4 to 8 hours) to freeze the entire volume. During this period, do not load the chamber completely and do not open the doors unless necessary to speed up the process of entering the operating mode.
