Thermostat is a thermoregulating device that is responsible for control of boiler operation depending on air temperature.

There are thermostats indoor and outdoor(street). Sensors can also be used for the street.

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

Room appliances have a greater impact on tactfulness(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 consumption for space heating.

Types of thermostats for Baxi gas boilers

Devices for Baxi are thermostats compatible with gas boilers Italian brand.

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

• installation location;
• operating principle;
• control method.

Depending on the location of installation, devices are divided into indoor and outdoor. Indoor ones are used more often than outdoor or street ones, as they do not require protection from difficult weather conditions.

Street options are used in cases where the owner of the house strives to make the operation of the equipment as accurate and economical as possible. The combination is especially effective in such cases room thermostat and street sensor , which Baxi units allow.

According to the principle of operation, the thermostat can be mechanical or electronic. In the first case You must manually set the air temperature. In the second— a program is installed according to which the boiler changes its operating intensity automatically.

Control method mechanical thermostat is manual installation regime turning the knob or pressing the buttons. The electronic or programmable option can operate remotely. In this case, the sensor is located in any part of the room, and control occurs from the remote control, computer or phone. At the same time, contact with gas equipment remains wired.

How to choose a Baxi thermostat

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

Attention! Check carefully compatibility thermostat with the gas boiler for which it is purchased. Remember that devices one company interact best with each other.

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

And vice versa, if heating and hot water are needed all year round and an expensive unit model is used, it is better to install a programmable thermostat.

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

This feature is implemented in most advanced models.

Calculation technical requirements to the thermostat is made based on the requirements for the operation of the boiler. For example, if the owners go to work in the morning and return only in the evening, it will be suitable thermostat with programmer, which will reduce the heating temperature and fuel consumption while no one is 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 for the system: it automatically turns on the boiler if the air temperature drops up to +3°C. Such technical characteristics has, for example, room thermostat Baxi Magictime Plus.

Where to post

An important condition Correct operation of thermostats requires accurate measurement of air temperature. Although all devices have errors up to several degrees, it can be minimized.

To do this, the room thermostat must be installed away from drafts and at a considerable distance from heating devices.

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 more accurate sensor indicators, those work more efficiently boiler and lower fuel consumption.

What materials are needed for connection

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 to the wall.

What tools are required for installation

To connect the thermostat you may need:

• screwdriver;
• drill;
• side cutters;
• thermometer.

Side cutters You 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 get twisted in screws, on which the device is attached. Need for dowels disappears if the wall is wooden.

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

Connection procedure

During the connection period, both devices should not work. To connect the thermostat and gas boiler, you need to study technical passports both devices and follow the wiring diagrams and instructions. The ends of the cable for the thermostat must be attached to the designated gas boiler contacts.

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

How to check the operation of the device

To check the device you need to set maximum temperature. Then you need to turn on the gas boiler and bring it to mode with maximum coefficient useful action (efficiency).

Upon reaching comfortable temperature you need to accurately measure it next to the thermostat and set it as a threshold for turning off.

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

Designed for all wall and floor standing gas boilers

Sensor outside temperature changes the temperature of the water supply to the heating system depending on the outside temperature. It serves to maintain constant thermal regime indoors, 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 established control curve. In this case, the consumer receives increased comfort and gas savings due to taking into account real weather conditions.

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

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

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

The digital control panel not only allows you to easily configure and instantly diagnose the boiler, but also remembers the latest errors in the system. The room temperature and hot water temperature can be set directly on the remote control panel. Controlling the boiler has become easier thanks to the clear display of all information on a 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 rational energy consumption. The control panel can be installed directly on the wall, or in a standard built-in installation box for light switches.

For the convenience of heating the room and saving fuel consumption, Luna-3 Comfort boilers provide the connection of an outdoor temperature sensor 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 specified climate curve. Luna-3 Comfort boilers can also be used for low temperature systems heating ("warm floors" mode 30-45°C).

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

Where to install the sensor?

The best place to install the sensor on the street is the north side of the house; the installation is made as high as possible from ground level. If it is not possible to install the sensor on north side, try to choose a place as close as possible to this direction; the installation site of the street sensor should not be sun rays, should be placed in the shade, under a canopy, around the corner from the sun. The outer box in which the outdoor temperature sensor is located is made of plastic with waterproof connections, moisture and condensation cannot get inside the box.

Baxi boilers are an excellent choice for autonomous heating systems. They are distinguished by increased comfort, varied automation and ease of use. Any additional equipment can be connected to the boiler. An example is 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:

• Connectivity additional elements, sensors and automation systems.
• The ability to automatically change temperature conditions depending on the temperature delta outside and at home.
• Economical operation.
• “Smart” self-diagnosis systems.
• The possibility of using the unit not only in traditional heating networks, but also in the “warm floor” system.

Additional accessories

Note! Most models are equipped as standard with built-in electronics, control systems and a variety of sensors. Installation additional accessories facilitates operation, making it simpler, more convenient and more efficient.

Additional accessories open whole line capabilities for equipment management:

• Temperature regulation according to time of day and time of year.
• Setting the temperature in different rooms.
• Work in economical 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 increase the cost of the system. But on the other hand, it will save on heating bills.

Installation pays off additional devices already in the first two heating seasons. So accessories to gas boilers Baxi is not only additional comfort, but also significant savings fuel.

Variety of accessories

Accessories and additional equipment There are a lot of Baxi boilers on the market. We list the main ones:

Clear display

• Digital timer. The device allows you to program the work utility networks for a certain period. When using it, the boiler will turn on/off at the time specified by the consumer. You can use this device 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. A boiler equipped with a programmer will operate in automatic mode. In this case, no intervention from the consumer in the operation of the unit is required.
• Outdoor temperature sensor. To maintain heat in the house, it is necessary to take into account the temperature of the outside air. The delta (difference) between room and street temperatures directly determines the power with which the boiler must operate. Sensor outside temperature allows you to maintain a constant mode no matter what the weather is outside the window.
• Room temperature sensor. It is recommended to install it together with the device described above. 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, but also diagnostics of the system occurs. This device can be used in conjunction with the programmer or separately from it.

These are not all the accessories that can be connected to Baxi indoor 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 essence, a thermostat is a device that allows you to regulate the temperature in a room automatically. It can be argued that it is easy to regulate the operating modes of the boiler without automation, that is, manually. At the same time, the thermostat becomes an unnecessary luxury, attracting extra costs funds. Let's consider 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 outside temperatures change, it is necessary to change the parameters of the heating system, and this must be done manually. As a result, intervention in the operation of boiler equipment is required throughout the heating season.

The time and attention required by the boiler when manual adjustment his work is not the best important issues. In this mode, frequent starts/shutdowns of the boiler occur, which is not the most in the best possible way affects 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 circulation pump continues to function. Being an energy consumer, it increases electricity costs, which increases financial costs for heating. Not to mention negative impact for the operation of the system.

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

The frequency of starts/shutdowns is significantly reduced. When programming the device, you can set the optimal threshold for triggering such a sensor. In addition, you can set a delay time for turning on or off the boiler when the sensors are triggered. This will minimize the likelihood of starting the heating device during 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 fuel consumption. When the boiler is turned off, the circulation pump is automatically turned off, which saves energy. All this speaks in favor of installing room thermostats.

The return on investment for such accessories is beyond doubt. Present on the market various models thermostats, differing not only in technical parameters, but also in price. Finding the optimal accessory is not difficult. Examples include 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 heating device either by wires or using wireless networks. The latter are more expensive, but more convenient and effective.

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 building structures. The case is attached using self-tapping screws, after which all the necessary electronics are connected and the necessary parameters are set. Such a device can operate remotely. It can be used 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 interfere with the efficiency of the system in the future:

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

Additional options

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

• Possibility of turning off the heating for several hours, for example, if there are no people in the house for a long time.
• Possibility of temporarily changing all programmed operating modes.
• Possibility of changing the temperature 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 installing such useful device still remains strong. This often encourages home DIYers to do everything themselves. And not only to install the device yourself, but also to assemble it from scrap materials.

Installation process

Theoretically, it is possible to make a thermostat with your own hands. To do this, you will need a thermistor that reduces resistance when heated. Then another resistor is connected to the network, with the help of which the temperature will be programmed. The 2I-NOT element 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 either on a mole rat or on a printed circuit board.

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

In order not to make a mistake in choosing a programmer and purchase suitable model, just stick to it simple tips specialists:

Features of choice

• It is advisable that the boiler and its accessories are manufactured by the same manufacturer.
• Powerful models of heating equipment can be operated with any programmer options.
• Before purchasing, you should calculate the necessary technical specifications, 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.

Any doubts left? You can always buy a cheap model with minimum set functions and options. Its operation will clearly show how feasible it is to install 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 just one room thermostat can reduce heating costs by approximately 25–30%.
