How to set the Baksi boiler to the economy mode. BAXI thermostat

Energy prices rise regularly, and gas is no exception. Therefore, the owners of wall-mounted gas boilers are increasingly thinking about saving issues. In general, modern gas boilers are quite economical and heating an apartment or a country house is quite cheap compared to similar services of commercial organizations. In this article, we will look at what factors affect the efficiency of a gas boiler using the BAXI as an example.

Heat carrier temperature

Correct regulation of the coolant temperature will directly affect gas savings. In the basic configuration, boilers are mostly not equipped with a street temperature sensor, therefore, throughout the heating season, the user must independently choose the temperature of the coolant depending on changes in the weather: either add or decrease.

This is not entirely convenient, especially since baxi boilers allow you to connect a sensor as an option. Even in this case, the term weather-dependent automation can be used. Then, the regulation will take place automatically, depending on the climatic curve selected in the boiler settings, and the boiler will spend less energy on useless heating, which will lead to gas savings.

Boiler cycle

Cycling is the frequency of switching on of equipment for heating the coolant. If no external control devices are connected to the baxi boiler, the interval between switching on the boiler can be set to a maximum of 10 minutes (by default, 3 minutes).

For example, for the BAXI ECO FOUR boiler this is the responsibility of the configuration parameter F11 Burner waiting time between two starts.

Frequent switching is not economical - the more time the boiler will work continuously, the better. On one of the forums, the user expressed concern about the long-term continuous operation of the boiler, but this, on the contrary, means that a mode has been established in which the heat losses of the room are continuously compensated while maintaining the optimal temperature of the coolant.

This problem is most urgent for owners of small-sized apartments, because the boiler is initially envisaged, including for the preparation of hot water and obviously higher power.

Since the numbers of the configuration parameters of gas boilers may differ, then to configure a specific model, you need to study the instructions.

How to set the Baksi boiler to the economic mode?

For small apartments it is recommended to set the parameters F08 (Maximum net heating power) and F10 (Minimum net heating power) to a minimum. The modulation range of a 24-kW boiler starts from 40% of the maximum power, so the minimum possible operating mode will be 9 kW, which will be quite enough for heating an area up to 80 sq. meters and will increase the intervals between inclusions, especially in the off-season.

In addition to saving gas, do not forget that each burner activation activates the main actuators, relay switching on the control board, fan, gas valve, which will certainly affect the resource of their work.

It should be noted here that the most economical mode of a gas boiler will be when operating at maximum power, that is, with maximum efficiency.

Room thermostat connection

Most models of baxi boilers have the ability to connect a room thermostat. The idea is that the boiler will turn on only by a signal from the thermostat when the room temperature drops below the set one.

Of course, everything is quite individual, and a lot depends on the type and balance of the heating system as a whole, and the use of only one room thermostat will have a certain inertia.

Programmable thermostats allow you to flexibly adjust different temperature modes throughout the day. Reducing the room temperature by 1 degree during the year will save about 4-5% gas.

In some European Union countries, where energy efficiency issues are more meticulous, the installation of a room thermostat is mandatory.

Zone control system

Such a system provides for individual temperature control in each room separately by installing controlled thermal heads on each radiator. That is, depending on the air temperature in a particular room, the amount of coolant in the radiator will be regulated, and the boiler will turn on only when necessary. The use of such regulation will give maximum savings (about 30%) and indoor comfort. The only disadvantage of such a system is its cost.

Savings and regular maintenance of equipment

The basic structure of a traditional gas boiler is almost the same, regardless of the manufacturer. Heat energy from gas combustion is transferred to the heat carrier through a heat exchanger. There can be either one or two heat exchangers in the boiler. During the operation of any gas boiler, the outside of the heat removal surface is contaminated with soot deposits, from the inside with scale.

From practice, we can say that it is extremely rare that the system is filled with special prepared water or the water supply system is equipped with a water treatment system. This is especially true for apartment buildings, in which the owners receive a ready-made heating system together with the apartment.

The formation of scale and soot on the walls of the heat exchanger will gradually reduce the heat transfer characteristics and more energy will be consumed for heating.

Therefore, annual regular maintenance will definitely affect the efficiency of the equipment for the better! This applies in particular to boilers with bithermal heat exchangers, which, due to their structural design, are difficult to flush.

Thermostat is a thermostatic device that is responsible for boiler operation control depending on the air temperature.

Thermostats are indoor and outdoor (street). For outdoor use, sensors can also be used.

Baxi gas equipment has the ability to connect both room and outdoor thermostats and sensors.

Room appliances have a greater impact on timing(turning on and off) the boiler, and outdoor ones allow the unit to regulate coolant temperature. The air temperature outside and in the house is constantly changing, and the thermostat helps increase or decrease gas consumptionfor space heating.

Types of thermostats for gas boilers Baxi

Instruments for Baxi are thermostatscompatible with Italian brand gas boilers.

In terms of their functions, they do not differ from systems for other gas equipment. Typically, thermostats are distinguished by:

place of installation;
the principle of work;
way of control.

At the place of installation, devices are divided into indoor and outdoor. Indoor rooms are used more often outdoor or outdoor, since they do not require protection from difficult weather conditions.

Street options are used in cases where the owner of the house seeks to make the operation of the equipment as accurate and economical as possible. The combination is especially effective in such cases room thermostat and outdoor sensorallowed by Baxi units.

According to the principle of operation, the thermostat can be mechanical or electronic. In the first case it is necessary to manually set the air temperature. In the second- a program is set according to which the boiler changes the intensity of work automatically.

The way to control a mechanical thermostat is to manually set the mode by turning the knob or pressing the buttons. The electronic or programmable version can function remotely. In this case, the sensor is located in any part of the room, and control takes place remote control, computer or phone... In this case, the contact with the gas equipment remains wired.

How to choose a Baksi thermostat

Thermostats and sensors for gas boilers Baxi produced by the Italian company itselfso it's best to choose them. If this is not possible, it is necessary to look for a thermostat that matches the parameters that are usually indicated in technical data sheets of devices. In such cases, it is appropriate to consult a specialist who is well familiar with the Baxi brand.

Attention! Check carefully compatibilitythermostat with a gas boiler for which it is purchased. Remember that devices one firm interact with each other best.

When choosing a thermostat, it is necessary to consider whether the boiler is used constantly or only from time to time. If the house has an inexpensive unit model that rarely works, then enough simple regulator with a minimum of functions.

Conversely, if heating and hot water supply are needed all year round and an expensive model of the unit is used, it is better to install a programmable thermostat.

And if the cottage is involved smart home system, then the ability to control the device via the Internet will be very useful.

This feature is implemented in most advanced models.

The technical requirements for the thermostat are calculated based on the requirements for the boiler operation. For example, if the owners leave for work in the morning and return only in the evening, it will do thermostat with programmer, which will reduce the heating temperature and fuel consumption while there is no one in the house.

And also, if the house is geographically located in a cold region, then it is better to purchase a thermostat with frost protection of the system: it automatically turns on the boiler if the air temperature drops up to + 3 ° C.Such technical characteristics have, for example, room thermostat Baxi Magictime Plus.

Where to post

An important condition for the correct operation of thermostats is the accurate measurement of the air temperature. Although all devices have an error up to several degrees, it can be minimized.

For this, the room thermostat must be installed away from drafts and at a considerable distance from heating appliances.

It is better to install the outdoor sensor so that it is not flooded with rain or covered with snow. These precautions are due to the fact that what more accurate sensor readings, the more efficient the boiler operation and the lower the fuel consumption.

What materials are needed to connect

Connection materials are usually supplied with the thermostat. This is, first of all, the device itself, as well as installation cable and fasteners... With their help, the device is connected to a gas boiler and fixed on the wall.

What tools are required for installation

To connect the thermostat you may need:

screwdriver;
drill;
side cutters;
thermometer.

Side cuttersyou can strip the ends of the thermostat wires, but as a rule they already have terminals that are screwed to the contacts of the gas boiler for the remote thermostat.

A drill is needed for the holes in the wall into which the dowels are installed. They twist screwson which the device is attached. The need for dowelsdisappears if the wall is wooden.

A thermometer is needed to check the air temperature after starting the thermostat.

Connection procedure

For the period of connection, both devices should not work. To connect the thermostat and gas boiler, it is necessary to study technical data sheets of both devicesand follow the diagrams and connection instructions. The ends of the cable for the thermostat must be attached to the designated contacts of the gas boiler.

Then the cable must be pulled along the wall to the place where the thermostat is installed. After that, at the selected point (usually it is in the coldest living room), the device is screwed to the wall. Finally, setting up and checking the device.

How to check the operation of the device

To check the device, you must set the maximum temperature. Then you need to turn on the gas boiler and bring it to maximum efficiency mode (Efficiency).

Upon reaching a comfortable temperature, it is necessary to accurately measure it near the thermostat and set it as a threshold for switching off.

Then, within an hour, you need to check whether the thermostat turns on the heater when the air cools down within 0.5-2 ° C... If this happens, then the instruments are working correctly.

Designed for all wall and floor standing gas boilers

The outside temperature sensor changes the temperature in the water supply to the heating system depending on the outside temperature. It serves to maintain a constant thermal regime in the room, regardless of external temperature conditions.

When an outdoor temperature sensor is connected to the BAXI boiler, the weather-dependent automation built into the boiler board is activated and the boiler itself regulates the supply temperature to the heating system according to the set control curve. In this case, the consumer receives increased comfort and gas savings due to the consideration of real weather conditions.

Separately, let's say a few words about one of the brightest new products presented by BAXI in 2007 - wall-mounted gas boilers of the third generation Luna-3 Comfort.

The combined use of an outside temperature sensor and a room temperature sensor (not a room thermostat, but a temperature sensor!) In these boilers ensures the boiler self-adaptation. That is, the control curve of the dependence of the flow temperature on the outside temperature is calculated automatically.

The main highlight of the Luna-3 Comfort series boilers is a removable digital control panel, which is also a room temperature sensor. The remote design of the control panel allows you to install it in any convenient place.

The digital control panel not only makes it easy to configure and instantly diagnose the boiler, but also remembers the last errors in the system. The room temperature and hot water temperature can be set directly on the remote control panel. Boiler control has become easier thanks to clear display of all information on the wide LCD display and temperature control buttons. The remote control panel is also equipped with a two-level weekly timer and functions as a programmable room thermostat. This allows you to set the temperature regime for the whole week, thereby ensuring a rational consumption of energy. The control panel can be installed directly on the wall, or in a standard flush-mounted back box for light switches.

For the convenience of heating the room and saving fuel consumption in Luna-3 Comfort boilers, an outdoor temperature sensor is provided for the operation of the built-in weather-dependent automation. In this case, the boiler electronics changes the water temperature in the heating circuit in accordance with the preset climatic curve. Luna-3 Comfort boilers can also be used for low-temperature heating systems (underfloor heating mode 30-45 ° C).

Also boilers Luna-3 Comfort can be used in mixed systems with several temperature zones. For this, BAXI offers a wide range of special accessories.

Where to install the sensor?

The best place to install the sensor outdoors is on the north side of the house, as high as possible from the ground. If it is not possible to install the sensor on the north side, try to choose the place as close as possible to this direction, the place where the outdoor sensor is installed should not be exposed to sunlight, it should be placed in the shade, under a canopy, around the corner from the sun. The outer box containing the outdoor temperature sensor is made of plastic with waterproof connections, moisture and condensation cannot get into the inside of the box.

Baxi boilers are an excellent choice for autonomous heating systems. They are distinguished by their increased comfort, various automation and ease of use. Any additional equipment can be connected to the boiler. An example are programmers, or room thermostats for Baxi gas boilers.

Advantages of Baxi boilers

Main 24 Fi 24 kW

The advantages of Baxi gas boilers are obvious, and the capabilities of such units are multifaceted. We list only the main advantages of such boiler equipment:

The ability to connect additional elements, sensors and automation systems.
The ability to automatically change temperature modes depending on the delta temperatures outside and at home.
Economical operation.
"Smart" self-diagnostics systems.
Possibility of using the unit not only in traditional heating networks, but also in the "warm floor" system.

Optional accessories

Note! Most models are equipped with built-in electronics, control systems and a variety of sensors as standard. The installation of optional accessories makes operation easier, more convenient and efficient.

Optional accessories open up a whole range of options for controlling your equipment:

Temperature control by time of day and season.
Setting the temperature in different rooms.
Work in economy mode.

All this reduces gas consumption, which means it makes the system energy efficient and its operation economical. Paradoxically, most consumers refuse to install additional equipment for reasons of economy. Of course, the installation of these devices will lead to an increase in the cost of the system. But on the other hand, it will save on heating bills.

The installation of additional devices pays off already in the first two heating seasons. So accessories for Baxi gas boilers are not only additional comfort, but also significant fuel savings.

Variety of accessories

There are many accessories and additional equipment for Baxi boilers on the market. Let's list the main ones:

Clear display

Digital timer. The device allows you to program the work of engineering networks for a certain period. When using it, the boiler will turn on / off at the time specified by the consumer. This device can be used not only for programming heating, but also for boilers.
Room thermostat, or thermostat. This device maintains the set temperature and allows you to control the microclimate. The boiler equipped with a programmer will operate in automatic mode. In this case, no intervention on the part of the consumer in the operation of the unit is required.
Outside temperature sensor. To keep the house warm, the outside air temperature must be taken into account. The power with which the boiler must operate directly depends on the delta (difference) of room and outdoor temperatures. The outdoor temperature sensor allows you to maintain a constant mode regardless of the weather outside the window.
Room temperature sensor. It is recommended to install it together with the above-described device. Both devices, working in pairs, guarantee the so-called self-adaptation of the boiler.
Digital control panel. This is a real highlight. You can install it in a convenient place. With its help, not only control takes place, but also system diagnostics. This device can be used in conjunction with the programmer or separately from it.

These are not all accessories that can be connected to Baxi room gas boilers. You should dwell in more detail on the most common device - a thermostat, or thermostat.

Why do you need a thermostat?

Suitable thermostat

In fact, a thermostat is a device that allows you to automatically regulate the room temperature. It can be argued that it is easy to regulate the boiler operation modes without automation, that is, manually. In this case, the thermostat becomes an unnecessary luxury, entailing unnecessary expenses. Let's consider all the pros and cons of installing such accessories.

When gas boilers operate, the microclimate in the premises is controlled by changing the temperature of the coolant. When the set value is reached, the boiler turns off, and when it decreases, it turns on again. When the outside temperatures change, it is necessary to change the parameters of the heating system, and this must be done manually. As a result, interventions in the operation of boiler equipment are required throughout the heating season.

The time and attention taken by the boiler when manually adjusting its operation are not the most important issues. In such a mode, frequent starts / shutdowns of the boiler occur, which does not in the best way affect its performance, and the reliability of the system as a whole. There is one more problem. When the boiler is operating in constant on / off mode, the circulation pump continues to function. As an energy consumer, it increases energy costs, which increases the financial costs of heating. Not to mention the negative impact on system performance.

As you can see, manual control for a high-tech gas boiler is not the best option. Now let's consider what the thermostat can change. The device has room temperature sensors that monitor the temperature not of the water in the system, but of the air in the rooms. As a result, the boiler is turned on / off when there is a deviation from the set temperature regime, and not when the water heating decreases.

The start / stop frequency is significantly reduced. When programming the device, you can set the optimal threshold for triggering such a sensor. In addition, you can set the delay time for turning on or off the boiler when the sensors are triggered. This will minimize the likelihood of starting the heater in the event of a short-term drop in temperature, for example, as a result of a draft.

Model TAM011MI Seitron

As practice shows, installing a programmer allows you to save 25-30% of energy. The device does not allow excessive consumption of fuel. When the boiler is turned off, the circulation pump is also automatically turned off, which saves energy. All this speaks in favor of installing room thermostats.

The payback of such accessories is beyond doubt. There are various models of thermostats on the market that differ not only in technical parameters, but also in price. Finding the best accessory is not difficult. As an example, we can name thermostats TAM0 11MI, Menred RTC 70, Raychem TE Basic, DEVIreg Touch, Nest, domestic MCS 300, etc.

Central thermostat

This type of programmer is installed in the house and connected to the heater either with wires or using wireless networks. The latter are more expensive, but more convenient and efficient.

The main advantage of wireless thermostats is the ability to install them anywhere. At the same time, they do not disturb the interior, and their installation does not require any complex devices or destruction of building structures. The case is attached with self-tapping screws, after which all the necessary electronics are connected and the required parameters are set. Such a device can work remotely. Its operation is allowed not only with gas, but also with solid fuel boilers.

Installation rules

Room regulator

Installation of central thermostats is simple. But it is necessary to adhere to several rules in order not to disrupt the efficiency of the system in the future:

The regulator is mounted in such a way as to provide free air flow.
There should be no household electrical appliances, lamps, touch switches, additional heaters, etc. nearby.
The thermostat must be easily accessible.

Additional options

The main function of thermostats is temperature control. For greater efficiency, the devices have additional options:

The ability to turn off the heating for several hours, for example, in the absence of people in the house for a long time.
The ability to temporarily change all programmed operating modes.
The ability to change the temperature regime on certain days.

The benefits of installing a thermostat are obvious. The payback of the devices is also beyond doubt. Nevertheless, the desire to save money on the installation of such a useful device remains strong. This often encourages home "homemade" to do everything with their own hands. And not only install the device yourself, but also assemble it from scrap materials.

Installation process

Theoretically, it is possible to make a thermostat with your own hands. This requires a thermistor to reduce resistance when heated. Then another resistor is connected to the network, with the help of which the temperature will be programmed. Element 2I-NOT will operate in inverter mode, and voltage will be supplied to it. A capacitor is connected to it and to the trigger. To control the relay, the galvanic isolation on the triac is enhanced. The device can be made both on a mole rat and on a printed circuit board.

With such a simple scheme, you can assemble a thermostat for almost any boiler. But is it worth interfering with the operation of high-tech equipment? It's up to the owner of the house to decide. Experts do not advise experimenting with homemade devices, especially since you can pick up accessories for any boiler on the market.

In order not to be mistaken in choosing a programmer and purchase a suitable model, it is enough to adhere to the simple advice of specialists:

Selection features

It is advisable that the boiler and its accessories are made by the same manufacturer.
Powerful models of heating equipment can be operated with any programmer options.
Before buying, it is worth calculating the necessary technical parameters, otherwise there is a high probability of equipment downtime.
If it is necessary to install a device of a high power class, it may be necessary to change the wiring, so it is better to consult a specialist.

Do you still have doubts? You can always buy a cheap model with a minimum set of functions and options. Its operation will clearly show how expedient the installation of expensive additional accessories.

Conclusion

Additional accessories for Baxi gas boilers are not a luxury, but an opportunity to make the heating system energy efficient in the full sense of the word. Installing only one room thermostat can reduce heating costs by about 25-30%.
