Windows in winter operating mode. Winter and summer mode in plastic windows: switching methods, malfunctions and their elimination. What are they and why are they needed

It is not enough to install a PVC window block in the opening. It still needs to be properly adjusted so that the sashes close tightly and without problems. Also, periodic adjustment of the window then must be done independently or with the help of craftsmen in spring and autumn, in order to transfer it to summer or winter operation. Moreover, this setting should be treated with all the attention. This is necessary not only to get rid of drafts, but also to increase the service life of the translucent structure.

  • Winter and summer settings

    In winter, the plastic window should be buried as tightly as possible in order to minimize air exchange between the street and the room. No one needs outdoor cold in the house in winter. In summer, on the contrary, even when closed, it should provide some air circulation (micro-ventilation) so that the room is not too stuffy due to the heat.

    Seasonal adjustment of the home window by transferring it to the “summer” or “winter” mode is carried out using locking pins on the side of the opening sash. They are fixed rectangular or roller (round with a risk on one side or oval).

    Types of pins on plastic windows

    Depending on the type, adjustment of this fitting is done by turning manually, with pliers, a screwdriver or a hex key. At the same time, in some cases, before turning, the mechanism must be pulled towards itself, and only then rotated.

    How to adjust window pressure

    The window trunnion can be set in one of three positions:

    1. "WINTER" - with maximum pressure.
    2. "SUMMER" - with a weak clamp.
    3. Neutral (standard).

    In the first case, on the round trunnion, the risk is turned to the street, and the oval is set horizontally. In the second, the risk is installed inside, and the oval stands vertically. The third option - the dash looks up, the oval is fixed at an angle.

    Instead of a movable pin on the sash, some window block manufacturers install a non-adjustable locking element in the shape of a rectangle. In this case, it is possible to adjust the plastic window only by adjusting the screw on the mounting plate.

    Adjustment of the window for winter and summer periods

    The main point of the seasonal adjustment of window sashes is the need to constantly transfer them from "summer" to "winter" and vice versa. With a strong "winter" pressure, the rubber seal is compressed, due to which it gradually begins to deteriorate. Often, the owners of PVC windows are faced with the fact that after a few years this gum has to be changed. This happens precisely because the sash, according to the instructions of the manufacturer of the window product, is not transferred to the summer mode with a weakened clamp, but left after the winter as it is.

    How to adjust the hinges of the plastic window sashes?

    In addition to seasonal adjustment of the degree of pressure, adjustment of plastic windows is also carried out by tightening / loosening the screws in the hinges with which the sashes are attached to the frame. There are two of them - one from below, the second from above. They differ in design, so they are pressed in different ways.

    Variants of plastic window mechanisms

    It is necessary to adjust the hinges on plastic windows due to:

    • initially poor illiterate settings of the window block during installation;
    • natural wear of the seal;
    • inaccurate and rough closing of the valves;
    • shrinkage of the window structure;
    • wear parts of the swing-out mechanism.

    As a result of all this, the sash sags and does not pretend to be tight or does not close at all. However, to return it to its place, it is enough just to tighten the hinges. Moreover, you can perform such a pull-up on your own. You do not need to call the wizards from the company that installed the window. It is enough to have a screwdriver and a hex wrench handy. This is not repairing gasoline generators for the home or a submersible pump for dirty water, everything is much easier with window structures.

    Places for adjusting the plastic window

    Upper

    The top hinge is adjusted from the side with a hexagon with a fully open sash. After turning the screw clockwise there, the window leaf moves away from the frame, and when tightened against it, it is pressed down so that the barrel is less blown from above.

    There is also another bolt on the top swing-out mechanism for finer adjustment. But to get to it, you will have to press the blocker (set it strictly vertically) and turn the handle to the top ventilation (also to the vertical position). As a result, the sash on top should pull away from the frame, hanging on the bottom hinge and opening full access to the top one.

    Top hinge adjustment

    It is important not to overtighten the adjusting bolts here. There should be a small empty space between the sash and the frame, where, when the window is closed, a tilt and turn device made of steel will be placed.

    lower

    The bottom hinge also has two adjustment screws. One of them is located on the side at the very bottom. He is responsible for adjusting horizontally - he presses the sash against the frame or pulls it away from it.

    The second is located directly in the rotary mechanism itself. To get to it, you need to remove the plastic cap-overlay from the loop. This screw allows you to adjust the opening window leaf vertically (height). Turn clockwise - it rises, against - it falls.

    Bottom hinge adjustment

    Manipulations during self-pulling of the loops on the plastic window should be done very carefully and without applying excessive effort. Do not immediately tighten or unscrew the adjusting screw all the way. It is better to turn it a quarter of a turn first and close the sash to check to see how much it has become evener in the frame. And only then, if necessary, you can tighten the bolt even further.

    How to adjust the handle

    The handle on the PVC window unit is actually not regulated in any way and does not affect the degree of pressing the sash. It is not involved in adjusting the window, but is only a mechanism for attracting the opening leaf to the frame, as well as transferring the latter to the micro-ventilation position and opening from above.

    However, often the handle becomes loose or starts to jam. To tighten or replace it, it is enough to get to a couple of bolts. They are located under a plastic overlay located on the profile at the base of this window fitting. This plug needs to be slightly pulled and turned, the fasteners are immediately available.

    Arm adjustment

    If the handle turns hard or is stuck, then the problem usually lies not in it, but in the hinges and the top folding mechanism. These window elements are directly related to each other. A wave is possible when the metal elements are rusted. Then the lever inside the profile will not allow the handle to turn. To get rid of this problem, you need to lubricate the hinges.

    How to fix window problems

    Problems with window blocks are very diverse. In some cases, it will be enough to do the simplest adjustment of the plastic window with your own hands by tightening the adjusting screws, while in others you will have to change the broken fittings. Here, in many ways, as with heating - most often you can achieve comfortable temperatures in the room simply by adjusting the room thermostats for gas boilers. But in a number of situations, it will be necessary to rebuild the existing heating system with the replacement of some of its elements.

  • When installing a plastic window, the specialist will immediately adjust them. Do they need to be further adjusted? Why is this needed? How to adjust windows for the winter? How to adjust them for the summer? How to adjust in spring and autumn? What do experts advise and recommend about this? Let's try to answer the questions and understand the topic.

    Why do you need adjustment of plastic windows

    • So that the sash does not touch any fittings when closing and opening or window frame.
    • So that the sash joins the frame tightly and there were no drafts.
    • To make the window bring joy and satisfaction from use.
    • It is necessary to periodically adjust the valves so that later you do not have to pay for expensive window repairs in the event of a breakdown.
    • If the window starts to sag.

    Step-by-step instructions for adjusting for the winter

    In winter, you can check the quality of the plastic window installation. If you find a draft, then you do not need to immediately blame the installers for this. They did the installation according to daylight saving time. To eliminate the draft, you need to adjust the pressure of the plastic windows.

    Before starting work, you need to prepare:

    • Remove all debris and dust from the joints and joints with a damp cloth. Dirt must not get on the mechanisms inside the window and hinge.
    • The surface of the fittings is cleaned with a brush with hard pile.
    • All dirt is removed from rubbing mechanisms and used grease.
    • If the seals are worn they need to be replaced.
    • Adjusting screw and hinges are lubricated with silicone grease.

    Let's move on to adjustments:


    The roller should be rotated so that the line drawn on it looks towards the room.

    Step by step instructions - for the summer

    1. Before adjustment, you must preparatory work described above.
    2. Needed again before starting works lift roller.
    3. A hexagon is taken and turns to the right.
    4. roller needed put in place.
    5. This operation is repeated with all videos.
    6. To add fresh air in the summer it is necessary to loosen the window clamp.
    7. A hexagon is taken and with its help the eccentrics are unscrewed.
    8. Turn them to the right by a few millimetres.
    9. It is necessary to monitor the density of pressing.


    A hexagon is taken and turned to the right

    Adjustment for autumn and spring

    Adjustment for spring or autumn is optional, only if necessary. If this still needs to be done, then only the rollers need to be adjusted. They need to be screwed or unscrewed a little, depending on the season outside the window. In the off-season, you can loosen the hoes and put them in the appropriate mode.

    The rollers need to be screwed or unscrewed a little, depending on the season outside the window.

    Sash pressure adjustment

    • This is done by adjusting the locking pins. Their number depends on the size of the window.
    • If the pin is round, then you will need a round key for 4 to work. They have a special slot for this key.
    • Initially, the hoe is not in the center and shifted either up or down.
    • To press the sash, you need to insert the key into the center of the pin and rotate it left or right.
    • There is a small red dot on the top of the toe. If you turn the key to the right, then the red dot will look inside the room, which means that the doors will be strongly pressed.
    • If the point will face the street, the sashes will be loosened.
    • If the tip is oval, then you will need a mounting key to work.
    • To strongly press the sashes, it is necessary to deploy the pin perpendicular to the sash.
    • To reduce the pressure, it is necessary to turn the pin to a vertical position. It should be parallel to the window sash.


    It is necessary to adjust the window mode depending on the season very carefully. This work must be approached seriously and responsibly, because a person who is not experienced in this matter can break the window fittings and will have to call specialists and pay for repairs.

    Translation process:

    • First of all, you need to find all the eccentrics. Depending on the type of window fittings, there may be several of them. Usually these are three trunnions at the end of the sash from the side of the handle, one from the opposite end, where the hinges are installed, one on the upper plane, the other on the bottom.

    Comment

    Head of the team of the repair and construction company "Dom Premium"

    Ask a Question

    "Transition to winter mode is the adjustment of all eccentrics at the same time. If one of them is not transferred, it means that the clamp will be loose in some plane. And all the operations done before that did not make sense.

    "
    • Now you need to thoroughly clean the trunnions and other planes and parts adjacent to it. The goal is to prevent dust and dirt from getting into the eccentric displacement planes. That is, in this way the problem of eliminating the mechanical impact on the adjustable node is solved.

    • After that, it is recommended to lubricate the fittings.

    • If the pin head is round, we are looking for a mark by which the set mode is determined.
    • Now all the eccentrics must be turned one by one to the required position. This will require tools that match the shape of the recess on the head of the rotary mechanism. If the head is oval, then the translation is carried out with ordinary pliers.

    • Now we need to check if everything is done correctly. It is better to check with a notebook sheet, as described above. You won't find a better option.

    Be warned that some manufacturers of window fittings make eccentrics in the form of a recessed mechanism. That is, their hat is flush with the plane of the end face of the window sash. Before transferring eurowindows to winter mode, it is necessary to pull the caps of the trunnions out of the socket towards you. Rotate them to the desired position and then push them back into the sash.


    By the way, before switching windows to winter mode with a hexagon, you need to accurately select this tool. Its size is 4 mm. A fixture is made of tool steel in the form of a tool bent at an angle of 90 degrees. It is easy to work with him, because his principle of action is a lever that increases the effort several times.


    Video of the process of transferring plastic windows to winter mode

    The video below shows how to correctly switch windows to winter mode. It clearly shows another type of window fittings, where there is no need to use additional tools when translating. Everything is done by hand. To do this, the pressure roller is simply pulled towards itself and rotates freely about its axis. This is how the switch is made.

    Attention! Regardless of the set pressing mode, plastic windows open for ventilation in the standard way.

    Window fitting requirements

    The question of how to switch windows to winter mode is not only a simple turn of the pressure rollers. There are certain requirements that must be met:

    1. During the first year of operation, the standard position should be set. Rubber seals are still in good quality condition, so they can ensure a tight fit of the sash to the frame.
    2. You can not keep the winter mode in the summer, and the summer mode in the winter.
    3. The transfer must be carried out twice a year in accordance with the temperature outside. For example, if it is still warm in November, that is, there is a positive temperature, then you should not make a transfer to cold weather. Better to wait a bit.

    If even in the winter position of plastic windows between the sash, impost and frame it blows, it means that the rubber seals have worn out, their operational life has been exhausted. What to do in this case? Change to new ones. It's easy to do.

    Article

    The instructions contained in this article will help you find out what position the trunnion is in and figure out how to switch windows to winter mode without resorting to calling the master at home. The text contains an overview of the features and characteristics of window fittings, tips for its use and proper adjustment, as well as a visual video and photo with a clear description of this procedure.

    Metal-plastic double-glazed windows are widely used for glazing apartments and private houses. Such designs have the ability to make adjustments and set the degree of pressing the sash. Thanks to such an adjustment of PVC windows, the system can be switched to winter or summer seasonal mode. This feature is very convenient, although not all owners know about it.

    The presence of the adjustment function depends on the type of fittings used. This feature is not inherent in every type of windows, but only in modern modifications. There are several modes. Each of them has its own characteristics.

    Standard, summer and winter modes of plastic windows

    The standard mode assumes the middle position of pressing the sash. This means that the eccentric will be located in the middle. The window structure installed in this mode, in most cases, is able to work effectively both in winter and in summer. This ensures the optimum pressure level of the sealing material.

    In winter mode, windows are characterized by a tighter fit of the sash to the frame. Due to this, in the cold season, metal-plastic structures effectively retain heat, keeping it indoors.

    Summer mode is characterized by a less dense fixation of the sash. In this position, air currents circulate freely between the environment and the room. In other words, the effect of micro-ventilation is provided, due to which optimal microclimatic conditions are maintained in the heat.

    Note! Using the summer mode allows you to weaken the sashes as much as possible, which has a positive effect on the condition of metal-plastic windows that have survived a long winter. At the same time, it remains possible to protect the premises from dirt, dust and heat.

    Why is it necessary to adjust plastic windows for summer and winter mode

    The transition from one mode to another allows you to keep the window structure in a functional state and extend its service life. Adjustment involves changing the degree of fit of the sash to the window frame. In the winter season, the insulation material shrinks, and in the summer it expands. It, like all fasteners, can be protected from wear by adjustment, video and photographic materials with instructions describing how this can be done, there is enough on the network.

    Sometimes during operation there is a displacement of the sash. When it is warm outside, this does not cause inconvenience, but in winter, because of this, the temperature in the room can drop significantly. If this happens, you should check the condition of the frame. During the installation of metal-plastic windows, the craftsmen check the position of the sashes in each of the modes, as well as the absence of gaps between the parts. However, perfectly executed installation is not a guarantee that the sashes will not disperse over time.

    If windows are installed in early spring or winter, the structures are exposed to external influences:

    1. The outside temperature is rising.
    2. Under the influence of climate change, plastic begins to expand.
    3. The outside temperature is dropping.
    4. Under the influence of temperature changes, the plastic decreases in volume, while it is not always able to take its original shape.

    Similar processes occur if windows are installed in the summer. But first, the material contracts as temperatures drop, and then expands. At the same time, it is impossible to avoid changes in the technical characteristics of the product, therefore gaps often appear in the windows.

    The need to transfer plastic windows to winter mode or summer mode may be due not only to the seasonal transition, but also to a number of other reasons:

    1. Drafts from the window, carrying frosty air in winter and dust in summer.
    2. Sagging sashes due to worn hinges.
    3. Jamming of the sash in the ventilation mode.

    Note! During the operation of windows, the sealing material is subjected to severe wear. Therefore, it is very important to timely carry out the adjustment of plastic windows with your own hands when switching to winter / summer modes.

    How to check the possibility of adjusting plastic windows for the winter

    The possibility of switching between summer and winter modes is provided by special fittings. The availability of this function depends on the class of these parts.

    There are several types of accessories:

    1. Budget fittings - parts that have the lowest cost and are solely responsible for opening and closing the window structure.
    2. Standard accessories - the package contains standard and anti-burglary parts that allow you to prepare the window structure for summer or winter.
    3. Specialized fittings - includes anti-burglary and specialized parts that allow you to transfer plastic windows to winter or summer mode.

    Most modern manufacturers produce standard and specialized fittings with the function of switching from one mode to another.

    Most popular brands:

    • Siegenia Aubi;
    • Maco;
    • Roto.

    During installation, the user is not always provided with detailed information about the functionality of the fittings. To find out if the transition between modes is provided for in the window structure, you should examine the appearance and marking of the configuration, namely, the trunnions.

    An eccentric or trunnion is one of the elements of the furniture filling, which allows you to adjust the degree of pressing the sash to the frame of the metal-plastic window. This part is located on the side.

    If the trunnion contains special holes designed for the key, then the design has an adjustment function. This can be easily seen even in the photo of plastic windows, of which there are many on the net. As a rule, the marking is marked with the image of a hexagon, screwdriver or asterisk. In some cases, the regulating part has an oval shape, which also indicates that the window can be operated in different modes.

    How to determine which mode of plastic windows is set: winter or summer

    Before adjusting plastic windows for the winter, it is necessary to establish in what position the fittings are installed. There are several ways to help you find out how the sash is placed. In each case, the technique depends on the shape of the trunnion.

    How to determine the winter mode of plastic windows before setting up the fittings:

    1. A sheet of paper is taken.
    2. It is placed between the sash and the window frame so that one of the ends remains on the side of the room.
    3. The window closes.
    4. Then you should pull the sheet towards you.

    If the paper passes easily, then the structure is set to operate in summer mode. Otherwise, it will break.

    Useful advice! Manufacturers of metal-plastic structures advise operating windows in summer mode all year round. If there are no reasons for switching to the winter position of the sash, this procedure is not necessary.

    In addition, there is a way to visually determine whether the winter mode is set on plastic windows, photo examples with markings can be easily found on the Internet. According to this method, it is necessary to find a marking in the form of a dash, asterisk or dot on a round pin. Next, determine the direction of this mark. If the marking points towards the room, then the windows are set to summer operation. If the mark looks towards the street, then the design is set to winter mode.

    Pins are not only round, but also oval. The mode of operation in this case is determined by the nature of the placement of the eccentric. If it is turned vertically, then the windows are set for summer weather. In a horizontal position, the trunnion presses the sash to the frame as tightly as possible, which indicates the winter mode.

    Having determined the position of the sash, you can proceed to the solution of the question of how to switch the windows to winter mode, video instructions describing this procedure are presented on the network in large numbers.

    How to adjust plastic windows in winter / summer modes: video review and description

    To find out how plastic windows are regulated, it is advisable to read the manufacturer's instructions, study the descriptions and videos, which can later be used as a visual aid. If the work will be carried out without the help of a specialist, it is very important to fully understand the essence of the issue and act as carefully as possible, since there is a risk of damaging the fittings with a careless movement.

    How to switch windows to winter modeoperation: photoand description of the preparatory phase

    Preparing a window for customization begins with cleaning. To perform this procedure, you will need a certain set of tools and fixtures.

    This list includes:

    • a mop equipped with a telescopic handle;
    • means intended for washing window panes;

    • paper napkins or towels;
    • means intended for cleaning accessories;
    • silicone-based lubricant;
    • brush or hard brush.

    Useful advice! If you constantly take care of double-glazed windows and keep them clean, before adjusting plastic windows for the winter, you will not have to spend a lot of time preparing them.

    The preparation of the window structure is as follows:

    • glass is washed;
    • the frame is wiped;
    • dirt on joints and joints is removed;

    • with a brush or a hard brush, the fittings are thoroughly cleaned;
    • all window elements are wiped (especially areas with grease);
    • by applying a few drops of silicone grease, the fittings are processed;
    • pin position is determined;
    • the pin is set to the required position;
    • relubrication;
    • all hinges are lubricated.

    After all the above manipulations are completed, the result is checked using a sheet of paper.

    How to switch windows to winter mode: photoand recommendations

    To adjust the fittings on double-glazed windows, you will need a special tool. Experts recommend bringing with you:

    1. Pliers.
    2. Screwdriver.
    3. Hex key.

    The necessary tool should be purchased immediately after the purchase of windows, as the need to configure them may arise suddenly. Sometimes eccentrics do not protrude, and many owners search the net for videos on how to adjust plastic windows with similar features. The secret is to pull the trunnion out. After that, it can already be configured. When the eccentrics are in the required position, they should be sunk into the sash again.

    Experts do not recommend changing modes in the first year of operation of windows. In new designs, the sealing material has not yet been subjected to wear, therefore, mechanical loads on the fittings should not be increased and adjusted. If the winter in the region does not differ in too low temperatures, the operation of double-glazed windows in summer mode is allowed. At the same time, winter adjustment should not be left for the summer, since in such a mode accelerated wear of the seal will occur.

    Note! Mode change is allowed to be performed no more than 2 times a year. Moreover, the length of the winter period of operation is much shorter than the summer one.

    Setting up plastic windows: how to adjust the sashes horizontally and vertically

    Regardless of the mode of operation, it is not allowed for the structure doors to be skewed. Sometimes you have to resort to correcting their position in order to correctly set up the fittings. The presence of sagging or distortion will shorten the life of the seal. To work, you will need a pencil with a soft lead and a ruler. All manipulations with the window must be performed very carefully, otherwise you can ruin the plastic.

    Preparing a window for sash adjustment:

    1. The structure is closed.
    2. The sash is outlined with a pencil around the perimeter (marks are applied to the frame).
    3. The window opens.
    4. The distances between the frame opening and the marked lines along the entire perimeter of the structure are measured.

    On all sides, the indicators should be the same. A slight deviation is allowed, but not more than 7 mm. If the level of the left edge is underestimated in relation to the right, or vice versa, you need to correct its position. To do this, you will need to remove the decorative insert and tighten the screws that are installed at the bottom.

    In some cases, it becomes necessary to raise the sash. To do this, the upper screw is unscrewed halfway. If the sash placement level is too high, the fasteners are screwed in ¼ turn. If it is clearly underestimated, the bolt is unscrewed ¼ turn. The horizontal adjustment of the sashes is carried out by means of screws that are located on the hinges.

    How to adjust plastic windows horizontally:

    1. The window opens.
    2. A hole is found, the configuration of which corresponds to a hex key.
    3. The screw turns smoothly until the sash is aligned to the desired position.
    4. A check is in progress.

    To check the quality of the setting, you should close the window structure. If it is necessary to reduce the distance between the hinge and the sash, the hex key must be turned clockwise. If the distance between these elements is too small, then the tool rotates counterclockwise.

    Important! A strong horizontal displacement of the window is not allowed. The maximum allowable indicator is 3 mm (in either direction).

    Possible problems with metal-plastic windows and ways to solve them

    You can check the quality of the work performed not only with a sheet of paper, but also by ear.

    A well-adjusted window behaves like this:

    • nothing prevents the free opening of the valves, they close freely;
    • there is no creak, rattle and other extraneous sounds;
    • all the screws holding the sash in the desired position are screwed in approximately the same way;
    • around the entire perimeter of the window, the sealing material has the same thickness and shape;
    • after opening/closing the sash, the sealing material returns to its original shape.

    Changing the operating mode of a structure is sometimes accompanied by problems. If the roller does not turn, it may need to be pulled out of the slot on the retainer by turning 90°. If this does not help, the part must be lubricated with WD-40. This lubricant is in the form of an aerosol mixture in a can. It is designed for processing joints and threads.

    If, when switching to winter mode, drafts from the window do not disappear, then the life of the seal has ended. It is very easy to replace this material. It is enough to remove the old seal from the frame and the grooves of the sash and insert a new one in its place (by hand or with a blunt spatula). Since the material is welded to the profile in the corners, you will have to cut it to remove it.

    The information contained in this article clearly explains how to put windows on winter mode. Video, photographic materials and detailed descriptions of the procedure allow you to fully understand the features of adjusting double-glazed windows. Using this data, you can quickly and easily provide warmth and comfort in your own home when it's cold outside.

    On the one hand, such manipulations promise advantages, reducing heat loss through the window structure, and on the other hand, as a result of adjustment, the seal wears out quickly.

    How to transfer plastic windows to winter mode: video-instruction

    Reading 7 min.

    Modern double-glazed windows provide a comfortable indoor climate. However, they also need periodic adjustments. So, it is possible to adjust the degree of pressing the canvas to the frame depending on the season, which few people know about. It is not difficult to do this with your own hands using a hex key, screwdriver or manually, depending on the type of locking devices.

    Why regulate

    Different modes are needed for one simple reason - the change of seasons. Accordingly, there is a periodic drop or increase in temperature. The ability to close windows more tightly (or, conversely, less tightly) increases the flow of fresh air into the room in summer and reduces the outflow of heat to the outside in winter.

    If the window is constantly operated in the "winter" mode, this will lead to rapid wear of the seal due to the constantly high pressure on it. If you leave the summer mode for a cold period, then there will be drafts and significant heat loss in the room. As a rule, during installation, windows are set in a neutral mode (spring/autumn), and when the season changes (that is, 2 times a year), it is recommended to make appropriate settings.

    Leak test

    It is necessary to prepare plastic windows for the winter before the onset of the first frost. It is necessary to carry out a preventive inspection and check the tightness in the following ways:

    Types of adjusting mechanisms

    The degree of pressing the sash to the frame is adjusted using locking mechanisms (pins) located on the side and upper ends of the sashes. The appearance, number and location of these devices may vary depending on the manufacturer and price category of the double-glazed window.


    The most common include:

    • Round. On such trunnions there is some kind of mark (dash, risk, dot, asterisk). If it is directed towards the room, then the window is set to "winter" mode, to the street - "summer", up - "neutral".
    • Oval. Vertical position - "summer", horizontally - "winter", diagonally - standard "neutral".
    • Turnkey eccentrics. Shift into the room - "winter" mode, outside - "summer", strictly in the middle - "neutral".
