Designed for all wall and floor standing gas boilers
The outdoor temperature sensor 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 bright new products, presented by BAXI in 2007 - wall-mounted gas boilers of the third generation 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 is the removable digital control panel, which is also a room temperature sensor. Remote design control panel allows you to install it in any convenient place.
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. Room temperature and temperature hot water can be installed 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 heating systems (warm floors mode 30-45°C).
Luna-3 Comfort boilers 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.
Energy prices are regularly rising, gas is no exception. Therefore, 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 country house is quite cheap compared to similar services commercial organizations. In this article we will look at what factors influence efficiency gas boiler using BAXI as an example.
Coolant temperature
Proper regulation of the coolant temperature will directly affect gas savings. In the basic configuration, boilers are mostly not equipped with an outdoor temperature sensor, so throughout heating season the user must independently select the coolant temperature depending on weather changes: either increase or decrease.
This is not entirely convenient, especially since Baxi boilers allow you to connect a sensor as an option. In this case, the term weather-compensated automation can also be used. Then, regulation will occur automatically depending on the climate curve selected in the boiler settings, and the boiler will waste less energy on useless heating, which will lead to gas savings.
Boiler clocking
Clocking is the frequency of switching on equipment for heating the coolant. If the baxi are not connected to the boiler external devices control, the interval between turning on the boiler can be set to a maximum of 10 minutes (default 3 minutes).
For example, for the BAXI ECO FOUR boiler, configuration parameter F11 is responsible for this. Burner waiting time between two starts.
Frequent switching on is not economical - the more time the boiler operates continuously, the better. On one of the forums, a 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 optimal temperature coolant.
This problem is most pressing for owners small apartments, because the boiler was initially designed, including for the preparation of hot water and obviously higher power.
Since the configuration parameter numbers of gas boilers may differ, to configure a specific model you need to study the instructions.
How to set a Baxi boiler to economical mode?
For small apartments It is recommended to set parameters F08 (Maximum net power of the heating system) and F10 (Minimum net power of the heating system) to a minimum. The modulation range of a 24 kW boiler starts at 40% of maximum power, therefore the minimum possible operating mode will be 9 kW, which will be quite enough to heat an area of up to 80 sq. meters and will increase the intervals between switching on, especially in the off-season period.
In addition to saving gas, do not forget that each switching on of the burner activates the main actuators, relay switching on the control board, fan, gas valve, which certainly affects the resource of their work.
It is worth mentioning here that the most economy mode the gas boiler will operate at maximum power, i.e. with maximum efficiency.
Connecting a room thermostat
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 air temperature in the room 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 using only one room thermostat will have a certain inertia.
Programmable thermostats allow flexible settings for different temperature conditions during the day. Reducing the room temperature by 1 degree throughout the year will result in gas savings of about 4-5%.
In some EU countries, where energy efficiency issues are more meticulous, installing a room thermostat is a mandatory requirement.
Zonal 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 provide maximum savings (about 30%) and comfort in the room. The only disadvantage of such a system is its cost.
Savings and regular equipment maintenance
The basic structure of a traditional gas boiler is almost the same, regardless of the manufacturer. Thermal energy from combustion of gas is transferred to the coolant through a heat exchanger. There can be either one or two heat exchangers in the boiler. During operation of any gas boiler, the heat removal surface becomes contaminated with soot deposits from the outside and scale from the inside.
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. Especially it concerns apartment buildings, in which the owners receive a ready-made heating system along with the apartment.
The formation of scale and soot on the walls of the heat exchanger will gradually reduce the heat transfer performance, and more energy will be consumed for heating.
Therefore, the annual regular Maintenance will definitely affect the efficiency of equipment operation in better side! This especially applies to boilers with bithermic heat exchangers, which, due to their design, are difficult to clean.
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 of the 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 outdoor 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 boilers Baxi 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.
For this room thermostat you need to install 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 test 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 comfortable temperature you need to accurately measure it next to the thermostat and set it as a shutdown threshold.
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.
Useful video

In order for heating equipment to work correctly, it is equipped with special sensors that have the ability to take readings and transmit data. Baxi sensors are devices manufactured using the latest technologies and modern materials. Designed to provide the most accurate readings possible, they allow you to use your heating system efficiently and safely. household appliances. You can purchase original sensors for Baxi heating boilers at any time on the Geyser website.
Quality Baxi thermostats
One of the most important indicators in a heating system is the temperature of the coolant. To measure it, special NTC sensors are used to detect changes electrical resistance. These devices are capable of taking readings thanks to inverse relationship their resistance depends on the hot water temperature. The higher the degree, the lower the resistance, becoming zero when it reaches 100°C.
The Baxi boiler temperature sensor is directly connected to the main control board, which changes its parameters based on its indicators. In our warehouse you can find any types of temperature sensors. Whatever equipment you have, we will select high-quality and compatible spare parts for it.
Depending on the type of heating equipment, thermostats for the Baxi boiler are placed either directly in the body of the primary heat exchanger, or in some boiler models on the pipe leaving the primary heat exchanger. The devices can also be installed inside a heated room or outside. In this regard, thermostats for Baxi gas boilers can be divided into:
- invoices;
- submersible;
- indoor;
- external.
In addition, thermostats for Baxi gas boilers are divided according to the method of data transmission into:
- wired;

Baxi heating circuit temperature sensors are distinguished by their thoughtfulness and technical excellence. The developers have created them as practical and durable devices with excellent performance characteristics. Equipment equipped with such sensors will operate efficiently and reliably.
Original pneumatic relays for Baxi boilers
A pressure switch is a device that controls the operation ventilation system boiler and smoke removal processes. The body of the device is designed in such a way that on one side the inner membrane is exposed to Atmosphere pressure, and on the other, pressure flue gases. This allows you to record changes in the composition of the gas-air environment and make appropriate adjustments.
If necessary, Baksi draft sensors are able to turn the boiler burner on or off. All actions of the pneumatic relay are aimed at ensuring safe work heating equipment. If for some reason the air supply pipes become clogged, the pressure switch is activated and performs actions that protect the system from overheating.
The Geyser company sells foreign-made draft sensors according to affordable prices. Our product catalog contains many parts and spare parts from famous brands. From us you can buy a draft sensor for a Baxi gas boiler quickly and without problems. The product will be at your home within a few hours after ordering.
Reliable flow sensors
Flow switches are designed to control water flow. This small device is a very important part of any heating equipment. The device is usually included in the DHW circuit. There are two types of flow sensors:
- turbine;
- ferromagnetic.
The first ones are newer and are a tube with a magnet inside. The flow of water rotates the blades, which creates magnetic pulses transmitted to the control panel. The frequency of signal transmission determines the flow rate.
The latter are more common and look like a float with a magnet inside. When the water is turned on, the float begins to move, thereby affecting the reed switch microswitch, which transmits data further to the control board.
