How to adjust the temperature of the water in the faucet. How to adjust the room temperature. How to adjust the temperature in different brands of refrigerators

Each manufacturer lays down the mode in the operating rules based on common standards. The temperature setting of the Indesit refrigerator is made at the factory, but you can set it up in a small range yourself. This condition is also spelled out in the technical standards. Each refrigerator is regulated in the temperature sector, beyond which it is impossible to change the parameters

The choice of temperature conditions in the refrigerator depends on the requirements for the safe storage of food. For a long time, the stock of fish and meat supplies, deep-frozen greens, should be stored at minus 18-24 0 C. This is a freezer. Meat and fish can be stored at a temperature of about 0 degrees for several days. The compartment is called the freshness zone and is not available in all refrigerators. Dairy products, cheeses and sausages require a storage temperature of 2-5 0 C, raw vegetables will not deteriorate, they will not begin to germinate in a cool compartment of 6-8 0 C.

The conditions for the safe storage of food underlie the established temperature norm for zones in the Indesit refrigerator. A small adjustment range allows you to set the mode optimally for the family. But first you need to determine what the actual temperature is in the freezer and in the center of the Indesit refrigerating chamber.

How to set the temperature in the refrigerator Indesit

The refrigerator has only mechanical control, the thermostat is designed for 5 positions. The highest temperature is marked with the number 1, the lowest - 5.

A section is devoted to how to properly regulate the temperature in the instructions for the Indesit refrigerator. The manufacturer warns that the optimal mode is calculated for the average value. How much the temperature inside the chamber should be depends on the degree of loading, the ambient temperature. The criterion for an incorrectly set mode may be the continuous operation of the compressor, the formation of a large amount of frost on the back wall. There is no forced circulation system in cabinets without Know Frost, cold air descends to the bottom.

The temperature is set by turning the lamb, which is connected to the temperature controller of the Indesit refrigerator. This device is called a thermostat. Turning the knob changes the pressure force of the spring that closes the contacts. A stable thermal balance depends on the correct operation of the relay. The Indesit refrigerator control system includes a temperature sensor with an electronic control system. Where it is located depends on the model of the refrigerator, but the device must touch the wall and the evaporator tube. The manufacturer recommends using the factory setting, which ensures a long service life of the thermostat.

Temperature control in the two-chamber refrigerator Indesit

The two-chamber Indesit refrigerator has a temperature control panel, as in the photo, without numbers, with indicators above the camera images. The temperature setting in the Indesit two-chamber refrigerator is made separately for the freezer and the cold cabinet. There is an average risk on the handles, adjustment begins from it. Where to turn can be determined by the thickening colored line. It increases from higher to lower temperatures.

Before you start adjusting the temperature in the positive section of the Indesit refrigerator, you need to perform its actual measurement at the EKO mark. In a cabinet that has reached the standard temperature, a glass of water is placed in the center for 2 hours, the temperature is measured in it. If the indicator is 3-4 degrees, the mode in the cabinet is optimal. How to set the temperature correctly is written in detail in the instructions for the Indesit refrigerator.

If your actions to change the operating mode of the refrigerator are ineffective, you need to check the health of the thermostat. It can cause sub-zero temperatures in the refrigerator.

What temperature should be in the refrigerator compartment of the Indesit refrigerator

You can determine the average temperature in the freezer of the Indesit refrigerator by the number of stars in the marking. Three means freezing 18 0 C, 4 - there is a mode of short-term deep fast freezing. The coldest part is always in the upper compartment of the freezer, fresh food should be placed there for deep freezing, gradually lowering them lower. You can check the temperature in the boxes using a household outdoor thermometer.

It is possible to set the temperature as independent by departments of the freezer only in separate cabinets, an Indesit two-compressor refrigerator or in a system with electronic cold distribution. If the Indesit refrigerator has a “holiday” function, it is necessary to turn the pointer at the HOLIDAY risk, adjust the temperature to +12 0 С, the minimum mode in the thermostat range is set in the freezer.

We suggest watching a video on how to replace the thermostat yourself, since this is the most common breakdown that you can fix on your own.

The temperature in the refrigerator Indesit

An ordinary mixer can become a real assistant to the hostess if it is improved with a thermostatic device that automatically maintains the set temperature.

This is no longer a novelty, but a convenient device in everyday life. Mixers with a thermostat are electronic and mechanical. Some models do contactless which makes them even more convenient.

What is a thermostat?

The European community has long been accustomed to the reasonable consumption of energy, heat and water. That is why regulators and temperature sensors and much more, including mixers with thermostats, came into use from Europeans. All of them allow saving in the qualitative use of the benefits of civilization.

The temperature is switched by the regulator, usually in steps of 4 °C

It is noteworthy that in a mixer capable of always giving water at the desired temperature, there is no thermostat as such. But there is:

temperature scale, on which the desired indicator is set,
temperature limiter, it blocks its increase and always keeps it no higher than the given one,
heat regulator, capable of changing the ratio of cold and hot water so that the consumer receives water of a given temperature,
water pressure regulator, which turns the water flow on and off, making it as convenient as possible at the exit.

Before starting the mixer, the water temperature is set, and then its pressure is regulated. With the high-quality functioning of the device, it will be possible to have:

Water supply at a comfortable temperature.
Constant pressure of the water jet.

Virtually every manufacturer and kitchen has separate lines of thermostatic faucets. These can be simple but functional models, or they can be design masterpieces.

The principle of operation of mixers with a thermostat, both in cheap and in mega expensive devices, is similar. The main task is to mix the streams of hot and cold water to the desired temperature.

A thermoelement is installed inside the body, which prepares the water. The more powerful the device, the faster the thermoelement is able to regulate water flows, reducing one of them as necessary by increasing the flow of the other.

The principle of operation of a thermostatic mixer

Usually, the adjustment of water flows during the mixing stage is carried out in a couple of seconds, so the consumer does not notice any changes in temperature.

The nuances of the mixer with a thermostat

Some thermostatic faucets have a water blocker that completely stops the flow of water if it does not meet the set temperature. Such a device will never allow the user to get burned or, on the contrary, douse it with ice water. But in houses where water is supplied by public utilities with such a thermostat, you can not wait for water at all.

There is another point that may be unpleasant. In plumbing systems, where there are sufficiently large pressure surges, it happens that warm water starts to flow from a pipe with cold water instead. The thermostatic faucet will automatically turn off the hot water, lowering the overall temperature. Ultimately, the consumer will receive a weak pressure.

The water blocker will not allow you to get burned or splashed with cold water

The same thing happens when the hot water flow is not warm enough. In both cases, you will have to set a new temperature, which is not very convenient. If the pressure in the system is always stable, and the temperature drops in the water flows are insignificant, then using such a device will not cause problems.

Varieties of devices

Devices that prepare water to a comfortable temperature and serve it to the consumer differ, including by purpose. So, there are mixers with a thermostat for:

soul,
shells,
bidet.
universal use.

It is customary to divide devices also according to the method of attachment. There are faucets with thermostats, both for open (visible) and for closed installation.

The construction industry today produces faucets with thermostats of two types:

electronic,
mechanical.

Mixer with electronic thermostat

This device has a liquid crystal monitor, which displays the temperature indicators of the water being returned. Their control is push-button or touch. In such devices, you can create a number of programs and turn on the right one at a certain time.

In electronic - the temperature is set with buttons or a regulator and displayed on the screen

There are devices that are programmed to display additional readings, up to water analysis. The cost of such devices is several times higher than conventional electronic ones, not to mention mechanical mixers with an electronic thermostat.

Electronic devices are powered by batteries or by means of a mains adapter. The manufacturer can provide them with the ability to respond to special sensors, including infrared. Such remote control can be carried out even from another room.

The disadvantages include the fact that it is extremely difficult and not in every city.

Eternal as the world of mechanics

Mechanical models of mixers with a thermostat have levers, valves and handles, with the help of which the thermostat and water flow regulator are controlled.

In mechanical - the temperature is set by a rotary knob

In some cases, they are much more reliable and more adapted to Russian realities. At the very least, the temperature is switched here manually, and therefore sometimes faster.

The design of faucets with a mechanical thermostat is more minimalist and more diverse in style. Prices for branded devices start at 4,000 rubles.

The heating of the radiator occurs due to the circulation of a hot heat-carrying liquid in it. The higher the temperature and/or the volume of the coolant entering the radiator, the more it heats up, thereby raising the temperature in the room where it is installed. Accordingly, with a decrease in temperature and / or volume of liquid, the heating of the radiator decreases and the temperature in the room decreases.

To adjust the temperature of the radiators, various devices are used to create comfortable conditions in heated rooms. This allows you to significantly reduce costs, which is especially important for owners of country houses with autonomous heating.

In this article:

Overview of temperature controllers

All devices for controlling the heating of heating batteries can be divided into several main groups that differ in device and principle of operation.

Shut-off (overlapping) taps

Ball valve with two positions

The easiest way to adjust the temperature of the radiator is to install a shut-off valve at its inlet, which controls the supply of hot coolant from the heating system.

As shutoff valves, ball valves with two extreme positions are most often used - "open" and "closed":

in the open position, the largest volume of hot heat-carrying liquid enters the radiator;
in the closed position of the valve, the circulation of the coolant is completely stopped and the radiator cools down.

It is undesirable to leave the ball valve in an intermediate position, as this will quickly disable it.

With the help of shut-off valves, only very rough regulation of the room temperature is possible, requiring constant monitoring and manual control of the valves.

Manual valves

The principle of operation of the control valve is in a smooth change in the volume of the coolant entering the radiator in a certain unit of time.

This happens due to a change in the cross-sectional diameter of the valve passage.

Manual expansion valve

The valve consists of a valve with an inlet and outlet pipe and a cone-type locking head installed inside, connected to a handle with a graduated scale.

When the handle is turned in one direction or another, the locking head moves relative to the valve opening, increasing or decreasing the volume of incoming fluid.

The required temperature of the radiator is set by turning the adjusting knob according to the corresponding marks on the scale.

Benefits of manual valves:

simplicity of design;
reliability in work;
small cost.

The main disadvantage is the need for periodic monitoring and manual adjustment of the operation of the valves.

Automatic thermostats

This temperature controller for a heating radiator works by automatically changing the heating of the heater depending on the ambient air temperature in the room.

This happens by dosing the volume of liquid supply due to a smooth change in the valve flow area according to a signal from a built-in or remote temperature sensor.

Automatic thermostats are thermostatic and electronic.

thermostatic

The design of thermostatic thermostats consists of a through valve with a cone-type shut-off head and a thermal head installed on it, which controls the operation of the valve.

Built into the thermostatic head:

an ambient air temperature sensor mechanically connected to the valve locking head;
adjustment mechanism with control handle and adjustment scale.

The sensor is a temperature-sensitive element in the form of a sealed corrugated container (bellows) filled with a special volatile liquid or gas.

Sectional diagram of the thermostat

With an increase in temperature in the ambient air, the temperature-sensitive element expands and moves the shut-off head of the valve through the stem with a spring, reducing the diameter of its flow section and limiting the flow of coolant. As a result, the heating intensity of the radiator decreases and the temperature in the room decreases.

When the ambient temperature drops, the sensor's thermoelement shrinks and the coolant flow increases.

The value of the desired temperature in the room, which the thermostat must maintain, is set manually using a knob with a setting scale. If necessary, the thermostatic controller can be equipped with an additional remote temperature sensor connected to the main thermoelement by a thin capillary tube.

Advantages of such a regulator:

complete independence from the power supply;
relatively low cost.

Flaws:

special requirements for the location of the thermostatic element;
the need for additional adjustment of the device during operation.

Electronic

Electronic thermostat with control unit

This type of thermostat consists of a valve with a locking head and a control unit installed on it.

The control unit includes:

electronic temperature sensor;
control circuit (usually based on a microprocessor);
control panel with LCD display and buttons;
actuator in the form of an electromechanical relay.

The process of temperature regulation by this device occurs in the same way as in a thermostatic regulator, but at the same time, the movement of the shut-off head of the valve is carried out not by a thermoelement, but by the core of an electromagnetic relay according to a signal from the control circuit.

The temperature sensor and control panel can be remote, combined in one housing or separately. The regulator is powered by batteries or household power.

Electronic thermostats with microprocessor control have much greater functionality, allowing you to maintain the set temperature with high accuracy and program various operating modes by hours, days, etc.

Their main disadvantages are rather high cost and dependence of work on the availability of power supply.

Radiator thermostats

Thermostat for heating battery

A special type of device for adjusting the temperature of heating radiators is a thermostat with manual adjustment.

The principle of its operation, unlike conventional temperature controllers, is to change the temperature, and not the volume of the heat-carrying liquid. This happens due to the mixing of the cooled liquid leaving the radiator into the return line of the system into the hot coolant.

The advantage of this device is the simplicity and reliability of the design, and the disadvantage is the need to use additional sections of pipes and fittings for its installation.

Device and principle of operation

The thermostat consists of a mixing valve with three nozzles and a temperature sensitive element installed inside.

This element is a sealed container with elastic walls, inside which there is a special substance that changes its volume depending on the ambient temperature. The thermoelement is connected to the mixer shut-off head by means of a rod with a spring.

An adjustment mechanism with a manual adjustment handle is installed on top of the mixer body.

Depending on the temperature of the coolant supplied to the mixer, the thermoelement expands or decreases in volume, moving the stem of the locking head. This opens the return channel of the mixer.

The cooled liquid from the return line at the radiator outlet enters the mixer and, mixing with the hot coolant from the system supply line, cools it to the desired temperature.

When the coolant temperature decreases, the thermoelement decreases in volume and the liquid supply channel from the return line closes.

Maintaining the required temperature of the battery is carried out by an adjustment mechanism with a manual adjustment knob with a scale.

In addition to thermostatic, there are also mixers with an electromechanical or electromagnetic drive and remote control from remote temperature sensors and / or electronic control units. They provide more accurate automatic control of the set temperature in the apartment.

The disadvantages of such devices are volatility from the presence of a constant power supply and high cost.

Choose an installation location

Regulators are needed for rooms in which there is a frequent change in temperature regimes (kitchens, rooms on the sunny side), as well as where it is necessary to constantly maintain a stable comfortable temperature (bedrooms, children's rooms).

In private houses, control devices must be installed on the second floors, since warm air rising from the lower floors accumulates there.

The choice of installation location for a particular device is determined by its type and the location of the radiator itself. As a rule, the regulator is mounted between the radiator inlet and the coolant supply pipeline.

For stopcocks, valves and mixing thermostats their location relative to the space of the room does not matter, so the installation site is determined only by the convenience of access to them during operation.

Install thermostats on batteries with open space in front of them.

For automatic thermostats with built-in sensors temperature the place of their spatial arrangement in the room plays a big role, since the correct functioning of them largely depends on this.

This is due to the fact that the temperature sensor of the regulator measures the temperature of the air in the nearest surrounding space.

The value of the temperature measured by the sensor can be affected by direct sunlight, drafts, additional sources that produce cold or heat (refrigerators, various electrical appliances, etc.), including the heating battery itself.

If this condition cannot be met, use automatic regulators with remote temperature sensor, which can be placed in any convenient suitable place.

Methods depending on the area of \u200b\u200bthe room and the material from which the heater is made.

To maintain a constant temperature, you can additionally use automation for the boiler, namely, a room thermostat. available via link.

Installing and configuring the device

According to the classical scheme, the regulator is installed on the radiator inlet in accordance with the diagram of its connection to the heating system.

There is also an alternative installation scheme, in which the regulator is mounted at the outlet of the radiator. According to many experts, this improves the efficiency of heat transfer and the accuracy of adjusting the heating of the batteries by limiting the outflow of the cooled liquid from the heater.

The alternative scheme can only be used for manual and automatic thermostats, but not for thermostats.

Installing the temperature controller on the battery

The installation process itself is not particularly difficult and practically does not differ from the installation of other types of pipeline fittings. Before doing this, you should carefully study the instructions supplied with the device.

Why so few people do it right

Today, the refrigerator in most families is the main household appliance. Without his proper work, there will be no delicious food, no family harmony. One of the most important factors in this sense is a well-adjusted temperature. The more complex the technique, the more varied the settings and the more likely it is to make a mistake. How to avoid trouble and keep the freshness and healthy qualities of food in the refrigerator?

If the refrigerator temperature is set incorrectly

Most perishable products stay fresh for the longest time at temperatures from +2 to +5. If the temperature control in the refrigerator is turned too far, the food freezes, losing its beneficial properties. After defrosting, it quickly becomes unusable - you have to cook in a hurry. If it is too warm in the refrigerator, active reproduction of bacteria begins in the products: fruits and vegetables rot, sausage and cheese become moldy, juices begin to ferment.

Even more seriously, high temperatures affect frozen foods. A faulty temperature sensor in the freezer will turn fish or meat into a foul-smelling mass in a few hours.

Add to this the constant leakage of melted ice, as well as excessive energy consumption, and it becomes clear why it is so important to correctly regulate the temperature in the refrigerator. Unfortunately, not everyone even knows what the minimum and maximum operating temperatures are for the model standing in their kitchen. They twist the handle - it doesn’t freeze on the walls, it doesn’t drip into the pan - and thank God. And how to do it right?

Optimum refrigerator temperature

Since the refrigerator compartment is usually of a decent volume, the heat is not evenly distributed throughout it. Much depends on where exactly the compressor is located and how the refrigeration unit is structurally arranged. For some models, the cold zone is closer to the top of the case, for others it is in the middle. The closer to the place where cold air enters, the lower the temperature. To decide how to properly distribute food in the refrigerator, pay attention to the following facts:

At temperatures from +1 to +3 it is best to store meat, fish, chicken eggs, hard cheese, mayonnaise in an open package.

At temperatures from +2 to +4 sausages and culinary products, soft cheeses last longer.

At temperatures from +3 to +5 store soups, boiled vegetables, dairy products, bread.

For seafood, the most comfortable temperature is from +4 to +6 degrees. Fruits (with the exception of exotic ones - bananas, pineapples, etc., which are generally undesirable to be stored in the refrigerator) should be placed in the warmest place in the refrigerator compartment, where the thermometer shows +6 ... +8 degrees.

Based on this, you can roughly estimate how the food set will be distributed according to your refrigerator model.

As for the freezer, do not forget: frozen foods are equally stored both at -18 degrees and at -25°C. Therefore, chasing freezing power is not at all necessary.

Refrigerator temperature control

Oddly enough, most people do not even look at the instructions before turning on the refrigerator and adjust the temperature by randomly rotating the thermostat (in the case of electronic temperature control through the LCD display on expensive models, this procedure is still more correct). At the same time, it is far from always possible to make an accurate and correct adjustment. However, there are "folk" methods of control. Instead of trying to interpret arbitrary numbers on the switches, it's better to check the air temperature with an outdoor thermometer. Place it in a glass of water in the center of the refrigerator. Check the temperature after a few hours. If it is higher than +4 degrees, feel free to twist the regulator in the direction of cooling. If lower than 2-3 degrees, turn it in the opposite direction. Once you have stabilized the temperature within 3-4 degrees, put the thermometer between the frozen food bags in the freezer and wait a few hours. At temperatures below -25°C, turn the temperature control up, if above -18°C - down to lower the temperature.

How to adjust the temperature in different brands of refrigerators?

In modern units, it is possible to regulate the temperature of the freezer and refrigerator compartments separately, as well as different compartments independently of each other. Let us analyze the features of thermal control in models of leading manufacturers presented on the domestic market:

Gorenje- the temperature in the refrigerator is set by turning the regulator knob to a position between Max and Min. It is recommended to set the thermostat to ECO. If the air temperature in the room where the refrigerator is installed is below 16 degrees, the manufacturer advises to unscrew the handle to Max, and vice versa in ambient heat.
Liebherr- electronic temperature control, in many models - separate regulation in the refrigerator and freezer. There is a mode cool plus- a system that protects the refrigerator from temperature changes in the external environment. As soon as the air in the room becomes colder, the compressor of the device starts to work intermittently. SmartFreeze- a special cooling technology, in which, due to the active air circulation, it becomes possible to quickly freeze many kilograms of food at once. Modes of supercooling and ultra-fast freezing in the freezer.
Atlant- the temperature is regulated by turning the thermostat knob in both directions. It has a dial on it. The adjustment takes place on a seven-point scale: 0 - the compressor is off, 1 - the highest temperature, 7 - the lowest.
Samsung- the temperature is regulated using the control panel separately for the freezer and refrigerator compartments:

cooling chamber: press the Fridge button to set the required temperature in the range from +1 to +7 degrees. The default temperature is 3 degrees;
freezer: a the temperature is set from -14 to -25 degrees. The fast freeze function is available, which is activated for 72 hours, after which the freezer returns to normal temperature.

Bosch- the temperature is regulated similarly to the previous brand, there is also a super-cooling mode available for 6 hours (the temperature quickly and evenly drops to +2 degrees, cooling the products that have just been placed in the refrigerator - as a result, those lying next to them do not have time to thaw).
Indesit- the temperature inside the refrigerator is automatically adjusted according to the position of the thermostat knob: 1 - the warmest mode, 5 - the coldest mode.
LG- in many models, the temperature is controlled using the control panel separately for the freezer and refrigerator compartments.

Stinol- there are two independent regulators for a two-chamber unit. Five positions on both thermostats, supercooling mode is available in the freezer.

How to detect incorrect temperature control in the refrigerator?

Most often, it manifests itself either in the form of a crust of snow and ice growing on the walls of the device (in addition to the unaesthetic appearance, “hypothermia” also increases the energy consumption of the refrigerator), or in the form of a puddle flowing into the pan, or even pouring onto the floor. Products begin to deteriorate faster than usual or lose moisture and dry out in one to two days. There is an unpleasant odor in the refrigerator compartment. If you notice these symptoms, think about it: maybe it's just that you once did not take the time to read the instructions?

Diagram of the system with regulators

Each heating season presents its own surprises with the difficulties of space heating, both for residents of multi-storey buildings and private cottages. The quality of uniform heating of all rooms of the house depends on how the temperature of the radiators is adjusted.

Why do you need to adjust

Setting the optimal temperature of the radiators allows you to create the most comfortable conditions for your stay indoors. In addition, the adjustment allows:

Remove the effect of airing in the batteries, allow the coolant to move freely through the pipeline of the heating system, effectively giving off its heat to the interior space of the room.
Reduce your heating costs by up to 25%.
Do not keep windows open all the time if the air in the room is too hot.

Setting the heating and adjusting the batteries, it is advisable to do before the start of the heating season. This is necessary so that later you do not experience discomfort in the apartment and do not adjust the heating temperature of the batteries in emergency mode. Before setting up and adjusting radiators, it is initially necessary to insulate all windows in the summer. In addition, you need to take into account the features of the location of the apartment:

In the middle or in the corner of the house.
Lower or upper floor.

After analyzing the situation, it is advisable to use energy-saving technologies to maximize the preservation of heat inside the apartment:

Insulate walls, corners, floors.
Conduct hydro and thermal insulation of the seams between the concrete joints of the panel house.

Without these works, it will be useless to regulate the temperature of the radiators, since the lion's share of the heat will heat the street.

Types of heating systems and the principle of adjusting radiators

Handle with valve

In order to properly adjust the temperature of the radiators, you need to know the general structure of the heating system and the layout of the coolant pipes.

In the case of individual heating, adjustment is easier when:

The system is powered by a powerful boiler.
Each battery is equipped with a three-way valve.
Forced pumping of the coolant has been installed.

At the stage of installation work for individual heating, it is necessary to take into account the minimum number of bends in the system. This is necessary in order to reduce heat loss and not reduce the pressure of the coolant supplied to the radiators.

For uniform heating and rational use of heat, a valve is mounted on each battery. With it, you can reduce the water supply or disconnect it from the general heating system in an unused room.

In the central heating system of multi-storey buildings, equipped with the supply of coolant through the pipeline from top to bottom vertically, it is impossible to adjust the radiators. In this situation, the upper floors open windows due to the heat, and it is cold in the rooms of the lower floors, since the radiators there are barely warm.
More perfect one-pipe network. Here, the coolant is supplied to each battery with its subsequent return to the central riser. Therefore, there is no noticeable temperature difference in the apartments of the upper and lower floors of these houses. In this case, the supply pipe of each radiator is equipped with a control valve.
A two-pipe system, where two risers are mounted, provides the supply of coolant to the heating radiator and vice versa. To increase or decrease the coolant flow, each battery is equipped with a separate valve with a manual or automatic thermostat.

Types of control valves

Types of cranes

Existing modern heat supply technologies make it possible to install a special tap on each radiator that controls the quality of heat. This control valve is a shut-off valve heat exchanger, which is connected via pipes to the radiator.

According to the principle of their work, these cranes are:

Ball valves, which serve primarily as 100% protection against emergencies. These locking devices are a design that can rotate 90 degrees, and can let water in or prevent the passage of coolant.

The ball valve must not be left in a half-open state, as in this case the sealing ring may be damaged and a leak may occur.

Standard, where there is no temperature scale. They are represented by traditional budget gates. They do not give absolute accuracy of adjustment. Partially blocking the access of the coolant to the radiator, they change the temperature in the apartment to an indefinite value.
With a thermal head, which allow you to adjust and control the parameters of the heating system. Such thermostats are automatic and mechanical.

Conventional direct acting thermostat

Device principle

A direct acting thermostat is a simple device for controlling the temperature in a heating radiator, which is installed near it. By its design, it is a sealed cylinder into which a siphon is inserted with a special liquid or gas that clearly reacts to changes in the temperature of the coolant.

When it rises, the liquid or gas expands. This leads to an increase in pressure on the stem in the thermostatic valve. He, in turn, moving, blocks the flow of coolant. When the radiator cools, the reverse process occurs.

Temperature controller with electronic sensor

This device according to the principle of operation does not differ from the previous version, the only difference is in the settings. If in a conventional thermostat they are performed manually, then the electronic sensor does not need this.

Here the temperature is set in advance, and the sensor monitors its maintenance within the specified limits. The electronic thermostatic sensor regulates the air temperature control parameters in the range from 6 to 26 degrees.

Step by step instructions for adjusting the temperature

To ensure comfortable conditions of stay in the room, you need to perform some basic actions.

Wiring diagrams

Initially, on each battery, it is necessary to bleed the air until water flows in a trickle from the tap.
Then you need to adjust the pressure in the batteries.
To do this, in the first battery from the boiler, you need to open the valve by two turns, in the second - by three, and then in the same way, increasing the number of turns of the opened valve on each radiator. Thus, the coolant pressure is evenly distributed over all radiators. This will ensure its normal passage through the pipes and better heating of the batteries.
In a forced heating system, the pumping of the coolant, control of rational heat consumption will help to implement control valves.
In the flow system, the temperature is well regulated by the thermostats built into each battery.
In a two-pipe heating system, it is possible to control not only the temperature of the coolant, but also its amount in the batteries using both manual and automatic control systems.

Conclusion

Installation completed

Today, in order to maintain a comfortable temperature in the apartment, each radiator of the heating system must be equipped with an adjustment system.

Modern thermostats help not only maintain the heat balance inside the room, but also save energy costs for heating the coolant.
