Refrigeration equipment of the brand Posis, especially the Paracelsusseries, deservedly enjoys the trust of consumers due to its reliability and ease of operation. However, to ensure a long shelf life of products, it is necessary to set the temperature correctly. Errors in setting can lead to rapid spoilage of food or, conversely, to freezing.
Many users encounter difficulties during initial operation, not fully understanding how a mechanical regulator or electronic control panel works. In this article, we will analyze in detail the algorithm of actions for various modifications so that you can configure optimal microclimate inside the chambers.
Before making adjustments, it is worth remembering that the refrigerator takes time to stabilize. After connecting to the network or changing the settings, the compressor needs from 2 to 4 hours to reach the specified mode. Do not rush to draw conclusions about the incorrect operation of the equipment in the first hours of operation.
⚠️ Attention: Before starting any adjustments, make sure that the refrigerator is installed level and the gap between the back wall and the wall is at least 5-7 cm for free air circulation.
The principle of operation of the thermostat in Pozis refrigerators
Most models in the series Paracelsus use a mechanical thermostat. This device automatically opens and closes the electrical circuit depending on the temperature inside the refrigerator compartment. The adjustment is carried out by turning the handle, which changes the compression force of the spring inside the sensor.
The scale on the regulator usually varies from minimum (1) to maximum (5, 6 or 7). It is important to understand that the numbers on the scale do not indicate degrees Celsius. They point to work intensity the compressor. The higher the number, the colder it will be inside the chamber.
Mechanical thermostats are reliable, but require periodic checking. If you notice that the food in the refrigerator compartment begins to freeze when the handle is in the standard position, the calibration may have gone wrong or the sensor needs to be replaced. In such cases, simply turning the knob may not give the desired result.
- 🌡️ The number "1" means minimum cooling (warmest mode).
- ❄️ The number "Max" or maximum value means continuous operation of the compressor until extremely low temperatures are reached.
- ⚙️ Position "0" or "Off" completely turns off cooling, opening the motor power supply circuit.
Step-by-step instructions: how to set the temperature
The setup process depends on which modification Posis Paracelsus is in your use. Let's consider the standard algorithm for mechanical control, which is most often encountered.
First, find the thermostat. In classic models, it is located inside the refrigerator compartment, usually on the right wall or under the top shelf. In some new versions, the regulator may be placed on an external control panel, but the principle remains the same.
Turn the regulator knob to the position corresponding to the middle value of the scale (usually 3 or 4). This basic settingis recommended by the manufacturer for normal operating conditions. If the room is hot, you can add 1 division upward.
☑️ Setting the temperature
After installing the handle, you must wait. Do not immediately load the chamber with warm foods, as this will disrupt the sensor. Let the unit idle until it gets cold and shuts down. Only after the first cycle can you evaluate the result.
What to do if the compressor does not turn off?
If, after setting to the average value, the compressor runs continuously for more than 6 hours and does not turn off, there may be a freon leak in the system or the thermostat is faulty. In this case, you need to call a technician for diagnostics.
Optimal temperature conditions for different products
To maintain the freshness of products, it is necessary to maintain a certain temperature. In the refrigerator compartment Pozis the optimal range is considered to be from +2 to +6 degrees Celsius. However, different shelves have different temperatures due to natural air convection.
The top shelf is usually warmest; it is good to store ready-made meals, drinks and foods with a short shelf life there. The bottom shelves and the area above the vegetable drawers are the coldest places, ideal for meat, fish and dairy products.
If you store a lot of perishable food, it makes sense to move the regulator towards lower temperatures. However, you should not set the maximum value unless necessary, as this increases energy consumption and the load on compressor unit.
| Product type | Recommended temperature | Storage location in Pozis | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat | 0...+2 °C | Lower shelf / Freshness zone | 1-2 days |
| Dairy products | +2...+4 °C | Middle shelves | 3-5 days |
| Vegetables and fruits | +4...+8 °C | Bottom drawers | Up to 7 days |
| Ready meals | +2...+6 °C | Upper shelves | 1-2 days |
⚠️ Attention: Door shelves are the warmest place in the refrigerator. Do not store open milk, eggs (in the long term) or meat there, as if the door is often opened, the temperature there fluctuates greatly.
Super Freeze mode and its effect on temperature
Some models Posis Paracelsus are equipped with a Super Freeze mode. When this function is activated, the compressor goes into continuous operation, ignoring the readings of the refrigerator thermostat. This is necessary for quick freezing of large quantities of fresh food.
This mode should be used with caution. If you leave it on for a long time (more than 24-48 hours), the temperature in the freezer can drop to -24...-30 degrees, and in the refrigerator, the products at the back wall can freeze.
After loading the products into the freezer and their complete freezing, the super freezing mode is necessary turn it off manuallyby returning the regulator to the normal position. Otherwise, electricity consumption will increase significantly, and the engine life will be reduced.
Diagnostics: if the temperature does not hold
There are situations when the regulator is set correctly, but the food spoils or, conversely, freezes. This may indicate a malfunction. First of all, check the tightness of the sealing rubber around the perimeter of the door. If the rubber is worn out or dirty, the cold escapes out.
It is also worth paying attention to the evaporator. If in the Paracelsus refrigerator (which usually has a drip defrosting system) there are no patches of frost on the back wall or, conversely, “snow” has frozen over, this is an alarming sign. A uniform thin layer of frost that periodically melts is normal.
Check that the drainage channel for removing melt water is not clogged. Its clogging leads to increased humidity and disruption of heat exchange. You can clean the channel using a soft wire or a special brush, carefully inserting them into the hole at the bottom of the back wall.
Common mistakes when setting up a refrigerator
Users often make typical mistakes when trying to “improve” the operation of equipment. For example, setting the regulator to maximum in the summer in an attempt to cool warm food. This leads to icing of the evaporator and stopping of air circulation, as a result of which the products in the chamber become warmer.
Another mistake is frequently changing the settings. Don't turn the thermostat knob every couple of hours expecting instant results. The thermostat has inertia and changes take time to evaluate. Constant jumps in settings disrupt the automation algorithm.
Another problem is installing the refrigerator next to heat sources (batteries, stoves, direct sunlight). In such conditions, even a correctly configured Posis Paracelsus will work for wear, trying to compensate for external heating.
⚠️ Attention: If you change the position of the thermostat, do it smoothly, without sudden jerks. The mechanical contacts inside may not have time to switch or may be damaged during a sharp turn.
Questions and answers (FAQ)
Which position of the regulator to choose for summer and which for winter?
In summer, when the room is hot, heat inflows are higher, so it is recommended to install the regulator closer to the average values (3-4), but make sure that the compressor has time to turn off. In winter, if the room is cool, you can reduce the value to 2-3. The main rule: regulate according to the fact, checking the temperature of the food, and not according to the season.
Why do vegetables freeze in the Posis Paracelsus refrigerator?
Vegetables can freeze if the regulator is turned to the maximum (5-7), if they lie too close to the back wall (it’s cold there only +1...+2 degrees) or if the thermostat is faulty, compressor not switching off in time. Also check if the ventilation holes are blocked.
Is it possible to completely defrost a refrigerator without unplugging it?
No, this is impossible and dangerous. To defrost, you must completely disconnect the appliance from the power supply, remove all food and leave the doors open. Forced defrosting without turning off the power can damage the electronics and the compressor.
What does a flashing temperature indicator (if any) mean?
Flashing usually indicates that the temperature inside the chamber has risen above the permissible threshold. This may happen after switching on, after loading warm food, or during a malfunction. If the blinking does not stop after the camera cools down, diagnostics are required.
