GSM module for a boiler - how to select and connect

The uninterrupted and correct functioning of the heating system is one of the indicators of a comfortable life in any house or apartment. Using such modern equipment as a GSM module for heating boilers, you can remotely control the boiler room using mobile communications. But this is very convenient, don’t you agree?

We suggest you understand how the innovative control system works, what basic and additional functions the GSM module can perform. To help you understand how advisable it is to invest in the purchase of such equipment, we have listed the advantages and disadvantages of remote monitoring.

In addition, we have prepared a review of popular GSM module models, and also outlined the nuances of installing it, connecting to the phone and setting optimal parameters.

Popular models

GSM alarm Sapsan
GSM modules must be selected depending on the type of boiler equipment and the requirements for the controller.

The most famous models are:

Xital GSM with modifications 4T, 8T and 12T.
Sapsan Pro 6 – for any boiler equipment, connection of 10 rooms.
Telcom 2 – only for De Dietrich, up to 5 numbers.
Vitocom 100 – only for Viessmann, a maximum of two numbers can be connected.
Logomatic PRO GSM – only for Buderus, maximum number of numbers – 16 pieces.

Control system "Xital"

In the market of GSM alarms for heating equipment, the undisputed leader is the Xital system.

This is a powerful, comprehensive remote control system because in many cases it covers not only heating, but also home security.

The module accumulates data on the temperature in the room, pool, pressure in the circuits, collects readings from safety sensors, and simultaneously regulates the room temperature within a given range.

GSM module for boiler Xital 4T

There are several modifications of Xital - GSM-4T, GSM-8T and GSM-12T. They differ in the number of control zones - 4, 8 and 12.

Each device has an analog temperature sensor, as well as five external digital sensors that continuously measure temperature. 30 seconds after the sensors are triggered, Xital will send a message to telephone numbers (you can configure the equipment to turn off when an alarm is triggered).

Users can register up to 10 numbers, including regular landline numbers.

Startup order

The initial launch of the system is quite simple, you just need to follow the sequence of actions:

Insert a clean SIM card into the controller.
Plug in the power adapter.
Call your mobile phone to the number of the inserted SIM card.

The controller creates initial settings and templates for voice dial-up mailing lists; using Caller ID, your phone number will be entered into them. System startup is complete.

After about a minute, you can do a control check. To do this, call the controller's SIM card again. After the call is reset, you should receive a response SMS message with information about the temperature in the boiler and in the room, the state of the controller inputs, the presence of a network and the protection of the object.

The Xital package includes a battery, with which the module can continue to operate when disconnected from the electrical network. We recommend that you purchase an uninterruptible power supply for your gas boiler in advance, since the module’s battery only lasts for a short time.

Maximum operating efficiency of the entire system is ensured not only by its optimal connection diagram and the presence of automation, but also by the installation location and technical parameters of the heating batteries. In this sense, vertical heating radiators have many advantages.

Features Overview

Several factors influence the number of available options:

the number of channels and sensors for which the conditions for connection have been created;
variability of remote control, number of control modes;
possibility of programming heating parameters.

A standard set of sensors is responsible for scanning pressure, temperature, and the presence of carbon monoxide; additional ones can be connected for new functions. There are analogue and digital alarms, the former being more common.

The GSM unit with a set of working components provides the following tasks:

turning on, turning off, rebooting the heating system as a whole, the boiler and additional equipment;
regular information about the status and operating parameters of devices, current temperature conditions and emergency situations; in the event of emergency situations and breakdowns - shutdown;
additional sensors allow you to monitor any conditions that require a quick response - component failure, leaks, fire, home intrusion. The intelligent system solves some problems on its own, for example, turns off equipment in the event of a gas leak;
remote adjustment of temperature settings in each room and in the house;
the ability to protect the SIM card using a PIN code;
protection of the system from power surges.

The owner enters the lower and upper limits for each parameter in advance; if its value falls outside the specified range, a notification will be sent. Modern modifications of modules are capable of displaying equipment operation statistics in the form of time graphs. For ease of control, it is possible to send SMS to 2-10 numbers, thereby the whole family gets access to the system.

Possible additional functionality:

connecting auxiliary relays for installing new sensors;
monitoring pressure in a solid fuel boiler;
measuring the level of diesel fuel in liquid fuel equipment;
determining the quantity and quality of the remaining granules, pellets;
boiler feeder control;
activation of the emergency siren;
fire control by studying smoke indicators;
security using motion sensors;
protection against leaks, shutting off water in case of threat of flooding.

Block use modes:

auto. The scheme operates according to the entered restrictive ranges, analyzes information coming from the premises and from the territory, compiles and sends a general report on the work to the owner;
manual. Feedback is received from the user: he sends a message to change settings or receive information in real time;
alarming. Triggers in emergency situations: smoke, power failure, gas or water leakage, equipment stoppage or breakdown.

GSM boiler control provides for turning on, turning off, rebooting the system.
In alarm mode, the module can turn off the entire system or block a damaged component, and a notification will be sent to all numbers stored in the memory.

GSM module functions

Each specific module has a different number of functions, which depend on:

the number of channels, and accordingly, sensors that can be connected;
features of remote control and monitoring;
ability to adjust heating parameters.

A standard set of sensors scans temperature, pressure, and the presence of carbon monoxide. When setting up auxiliary ones, you will immediately receive expanded functionality. Such sensors can be digital or analog.

turning on/off the entire heating system;
the ability to turn the boiler on or off, reboot the device itself or auxiliary devices;
receiving information about the condition of the boiler daily, information comes in the form of mobile messages. The messages will contain the following data: temperature, equipment operating parameters; in the event of abnormal and emergency situations, they will be immediately displayed;
remotely changing the settings for the operation of an electric boiler, the temperature intensity in the whole house or in a separate room;
to avoid connecting third parties to the SIM card, you can set a PIN code;
control of electrical voltage stability (your unit will be protected from sudden changes in energy);
The controller operates in autonomous mode (this is provided by the battery). In the event of a power outage, the module will continue to operate on battery power.

In addition to the main functions of the modules, there are a number of auxiliary ones:

If desired, the user can connect an additional relay.
Turn on the emergency siren.
Launching auxiliary equipment and the ability to control it remotely using a gadget.

Module functions

Opportunities are determined by three factors:

Number of connected sensors and control channels
Firmware of the controller, determining the level of control and management.
Availability of feedback, control of the heating boiler.

Thermometers, pressure or carbon monoxide sensors can be digital or analogue, but the connection is determined by the capabilities of the controller interface. More often, the GSM module is characterized by the connection of analog sensors that produce a certain signal level or change their resistance.

Digital control and data interfaces are almost never used to control a heating boiler, but they allow you to connect equipment such as a security circuit or household appliances that are equipped with an RS-485, RS232 or even USB interface to the device.

As feedback, that is, boiler control, a relay block is used that can simply turn on or off the power of a gas heating boiler or switch modes if the boiler control unit has the appropriate outputs.

In the minimum set, the GSM module is capable of monitoring and transmitting to the user the readings of installed temperature sensors. This is quite enough to know the actual temperature indoors and outdoors and control the heating of the coolant directly in the boiler. Based on these data, it is already possible to judge the quality of the boiler’s operation, determine whether it is working or not, and whether its current installation is sufficient to maintain the set temperature in the room.

A common set of functions is sending an SMS message or calling the user with information:

On request. The readings of sensors installed in the system are transmitted.
According to the boundary condition.

In the first case, the user sends an SMS to the number installed in the GSM module with a specific code, or calls and requests the current status of the sensors through voice control. In response, he receives data on the actual value of the sensors by voice or SMS message.

The module independently transmits readings to the user or the established message format if the readings of one or more sensors are outside the set limit. You can set the minimum and maximum allowable value for each sensor, and if the current value is outside the specified range, the user will receive a message about this.

For example, if a temperature sensor is installed directly in the boiler to change the temperature of the coolant, then the limits of the minimum and maximum permissible values are set for it. Let's assume the optimal heating of water is 75°C. Then if the temperature drops below 50°C, it means that an emergency situation has arisen, and for some reason the boiler has stopped heating. It is no longer particularly important what happened, what is important is that the user needs to immediately check the equipment and prevent the home from cooling down.

The extended list of GSM module functions may include the following services:

Remotely configure set limits and thresholds for sensors.
Boiler control, on/off, changing the target water temperature.
Alarm about the presence or absence of electricity.
Alarm about activation of connected security systems, if the unit is used not only for a heating boiler, but also for an alarm system.
Advanced boiler control. Based on the value of the installed sensors in the room, in the boiler and outside, the controller, according to a given algorithm, controls the power of the boiler so that, regardless of any weather change, the optimal temperature is maintained in the house.

What are GSM modules for heating boilers?

A GSM module is a small device (controller), which essentially represents an alternative to boiler controls and automation. It receives a signal via cellular communication and transmits a command to the boiler or in the opposite direction: it informs about the status and operating parameters of the boiler and the heating system as a whole.

Why is it needed and how is it used

Typically, the primary purpose of purchasing a device is to save money and increase the operating comfort of the heating system. Any GSM module allows:

turn the heating boiler on or off completely;
control the temperature, for example, lowering the temperature during absence in order to significantly save money and restoring a comfortable mode even before arriving at home;
manage DHW circuit temperature parameters;
External temperature sensors included with almost any modern module allow you to more accurately maintain the temperature by measuring the air temperature in the room, rather than the temperature of the coolant. It is also possible to organize weather-dependent operation of the boiler.

But no less important, in our opinion, and indeed a higher priority for some buyers, is safety. The GSM module is capable of notifying:

about reaching the lower or upper specified temperature limit;
about turning off the heating boiler due to lack of electricity or gas supply, problems with the removal of combustion products, automation errors, depressurization of the system, etc. This is often a rather underrated feature that allows you to have peace of mind during long-term departures and, in the event of a malfunction, take timely measures to prevent freezing and damage to the heating system;
It is possible to configure alerts about temperature and other boiler parameters at a certain frequency.

An example of an SMS report on the status of the heating system of the EctoControl module. Notifications and control from the phone can be carried out using SMS and, depending on the functionality of a particular model: through a special application, web interface or voice commands. The GSM module can be connected to any boiler that has the ability to connect external control (having the appropriate terminals), both gas, electric or liquid fuel, and solid fuel.

Message about a malfunction of the boiler using the example of the ZONT H-1V module application.

Almost all modern models allow you to bind at least 2, but usually up to 5 or 10 numbers to the controller and report on each of the linked ones. Modern devices, due to the ability to connect other modules to them, allow you to organize even wider functionality: monitoring the level of liquid and even solid fuel (for example, pellets in an automatic feed hopper), monitoring the status of flow and carbon monoxide sensors, monitoring pressure in the circuits.

Design and principle of operation

The main element is the controller (electronic control board). It has a slot for a SIM card, without it the device will not work. Depending on the planned method of management and control, it is necessary to select the most profitable cellular operator and tariff, and constantly maintain the operation of the SIM card by topping up the account. Regardless of the method of transmitting the command, the controller receives it via cellular communication and converts it into a command for the boiler, which has priority over the operation of standard automation.

To improve communication quality, the controller can be supplemented with an antenna. To ensure uninterrupted operation during a power outage, most models are equipped with a built-in battery, so they can easily send an alert about the problem. Almost all modern models come with external temperature sensors (wired and wireless), information from which takes priority over measurements from boiler sensors.

Installation features from the consumer's point of view

Whoever installs the GSM module (you yourself or a specialist), be sure to make sure that these conditions are met:

Optimal humidity is maintained at the installation site, as when installing the boiler;
if there is no portable antenna, then check that there is nothing obstructing the signal transmission, for example, a concrete ceiling;
pay attention to the length of the antenna cable if you need to take it to another location;
connect the module when the boiler is turned off and through an RCD in order to protect the equipment from power surges;
Check in advance that the distance between the temperature sensor and the controller is no more than one hundred meters - for better communication.

At the beginning of work, you must enter the phone numbers to which information will be sent. Then you will receive a verification code in the form of an SMS.

When you purchase a new card, immediately top up your account with at least 300 rubles and ask the operator to turn off all messages with paid advertising so that it does not take up space and confuse the controller. Please note that the cellular operator in the area where such a module is installed must have an uninterrupted signal.

To connect to the module, you can use a SIM card from any cellular operator. The main thing is to make sure the continuity and quality of the signal

After installation, be sure to test the operation of the GSM module. Let someone go outside with the phone, and someone stay in the house. It is important to check how quickly messages will be received when certain changes in boiler operation occur.

The phone receives an automatic SMS report on the status of the boiler and other key indicators of the system. Hints help you set up your equipment correctly

It is also necessary to configure the temperature regime, which is regulated by street and room sensors. Before doing this, please note that the documentation for the boiler indicates the minimum and maximum temperatures at which it will operate without failure.

The room sensor is responsible for the thermal conditions inside the room. In some models it can be set for the whole week. For example, on weekdays, three types of temperature settings are relevant: in the morning and evening - high, because everyone is at home, during the day - low, at night - also low or closer to average for a comfortable sleep.

When the weather changes, the user of the gsm module can remotely change the air temperature in the entire house using a special application on the tablet (phone)

Everyone is at home on the weekend, so choose the heating that is most comfortable for the whole family. This mode is called “general”. If you want to set the temperature in individual rooms, then turn on “zonal”. It is responsible for heating the air in individual rooms.

In the “vacation” mode (the names of the modes differ among different manufacturers), the temperature is at the very minimum. In this case, you can remotely control the autonomous unit to change the temperature.

For example, while on the way home, send an SMS with a special code or simply enter the required number to change the temperature mode.

If plans change, the user can always remotely adjust a comfortable temperature regime and return to a warm home

If a boiler is also connected to the system, then you can change not only the water temperature, but also the heating system. When switching to summer mode, the boiler does not turn off, but operates at minimum power.

Please note that there is an “anti-freeze” mode, which turns on the boiler from time to time to maintain the correct operation of the entire heating system.

The outdoor sensor reacts to changes in temperature outside the window. Experts call this mode the most promising. If the temperature drops, the boiler automatically raises the temperature.

After installation, also test the feedback from the autonomous heating. To do this, send a message with a command code.

When a user sends an SMS with a code (feedback function), he receives a response with performance indicators of the heating system

Technically, communication is realized through a relay, which is directly connected to the gas boiler.

How to choose a GSM module for a boiler

When choosing a notification module, it is important to pay attention to its functionality and technical characteristics:

Control – settings are made using buttons on the touch panel and SMS commands sent from the phone. Programmers from leading manufacturers are controlled by special software. The companies Viessmann and Buderus produce programs for Android and iOS that allow you to quickly remotely access the boiler.

Equipment - depending on the selected model, the module is equipped with an automatic gas control system and remote room temperature sensors.

Number of control channels – this parameter determines how many temperature sensors and other equipment can be connected simultaneously. Standard models have two channels, one is used to connect a remote programmer for remote control of a gas boiler via GSM, the second is used to transmit signals via SMS messages.

Microprocessor - budget models of control units, have only a few simple functions and fixed operating modes. Premium class equipment, has a built-in weekly programmer for controlling the temperature of the gas boiler using GSM.

Battery – the control unit operates from the mains. In the event of a power failure, power is automatically switched to the battery. The battery capacity should be sufficient to ensure autonomous operation of the module for several hours. If power outages occur frequently, choose a battery with a larger capacity.

When choosing a module, they are guided by the recommendations of gas equipment manufacturers.

Cost of GSM remote control for boilers

A gas heating boiler with a GSM remote control module consumes up to 30% less gas. The initial costs of installing a remote controller will pay off within the first heating season. The cost of the remote control, depending on the chosen model and configuration, varies from 5-12 thousand rubles.

Some manufacturers of gas equipment offer consumers boilers with a built-in GSM control unit. In this case, you will need to buy remote room thermostats and configure them to operate the module.

How to install a GSM module on a boiler

It is not difficult to organize control over the operation of the boiler yourself. To do this you will need to do the following:

Using special connectors, connect the control unit to the boiler controller.

Insert the SIM card into the slot. To prevent third-party users from connecting, set a PIN code.

Enter all phone numbers to which alerts will be sent.

After completing all the manipulations, a verification code is sent from the phone, and in response you will receive a message about the operating parameters of the boiler. The information received will show that the unit is connected.

It is recommended that the installation of the remote control and GSM unit be carried out by qualified specialists - electrical engineers. Independent work is carried out at your own peril and risk, and is the reason for refusal of warranty service.

Remote control of air temperature and heating system, gas saving, remote control of power outages allow you to maintain a favorable, comfortable atmosphere in the house. When everything works stably, you can rest assured that GSM modules will be there to keep order.

How to connect the Zont GSM module to the boiler, see the video

Installation issues

If previously the GSM module was available only for electric heaters, today it is installed on boilers of any type.

The differences lie in the connection of the hardware that controls the continuity of the supply of electricity or fuel. For example, when installing on a diesel heater, you should connect a fuel level sensor in the tank.

You can do this yourself, but it’s better to play it safe and entrust the work to a specialist. A specialist will competently perform installation, which will ensure trouble-free operation of the device for a long time.

Connection rules:

The GSM module is installed in rooms with normal humidity.
It is positioned so that the transmission of GSM signals is not interfered with by reinforced concrete structures.
The GSM module is connected to the electrical network through a residual current device (RCD).

Setting up a GSM module via the website

The software in the smartphone is installed taking into account the operating system and updated. Before first use, insert the SIM card and enter the PIN code. The GSM module itself will prompt you to create an access code.

It is recommended that two people perform the functionality check. One person remains next to the boiler for control. Another goes outside and gives commands via SMS. The speed of receiving commands and the device’s response is recorded.

Rating: Manufacturers and models of GSM modules

A mobile phone can be used as a remote control in a remote access system. To do this, just insert the SIM card into your mobile phone and connect it to the boiler.

Each device contains instructions for use, as well as instructions for installing the module

To purchase such a module yourself, it is recommended to pay attention to the rating. It presents a selection of models for home use from various manufacturers

In addition to them, devices from the companies Wolf, Baxi, Buderus, Navien, Protherm, Vaillant are considered good products.

"Kotel OK"

The most popular on the market, one of the best and most inexpensive GSM modules for heating boilers made in Russia. In addition to the price, it is distinguished by its compact size, extremely simple and easy setup, and the presence of an application that can send commands, including in the form of SMS, which is an excellent option that allows you not to use tariffs with Internet access.

The functionality of the device is quite simple, the minimum required: temperature control, setting alerts, checking boiler operating parameters, and the module also has a built-in relay that allows you to turn the boiler on and off.

Among the disadvantages, it is worth noting a rather simple application with the minimum required functionality and an outdated interface, the presence of an external temperature sensor with a cable length of only 0.5 meters, which does not imply its installation in other rooms remote from the boiler room. The antenna is also not remote, screwed into the device via a threaded connection.

Cost: 3,990 rub.

XITAL GSM 4T

Another well-known, more professional and versatile device with a much richer package. The heating control functionality in it is approximately the same as in the previous “Boiler OK” - the minimum required, however, there are as many as 4 zones for additional devices (flow sensor, smoke sensor, motion sensor, flood sensor, door opening sensor, etc.). Also included is an electronic key and a reader (similar to those installed in intercoms), so you can influence the settings, if desired, only with an electronic key.

The main difference is the presence in the kit of two remote temperature sensors with a wire length of 10 m, as well as a remote wired antenna and a cord for connecting a backup external battery (unfortunately, there is no built-in one). Management and control can be carried out both via SMS and through the application.

The disadvantages, in addition to the lack of a built-in battery, are the ineffective and inconvenient, although understandable, application interface, less attractive appearance with exposed terminals and large dimensions

Please note that for heating you must choose a model with a “T” at the end

Cost: 8,640 rub.

EVAN GSM CLIMATE

Also known as ZONT H-1, it features a more modern and convenient application, with ready-made “Economy” and “Comfort” modes, as well as the ability to program boiler operating parameters. It is enough to configure the boiler operating pattern once and the module will automatically issue commands to the boiler to change parameters depending on the time or day of the week. Control via a web interface is also available. The standard package includes one remote temperature sensor and a remote antenna.

Perhaps the only drawbacks are the lack of a built-in battery and only one contact for connecting an external temperature sensor.

Cost: 6,780-8,840 rub.

ZONT H-1V

A more advanced analogue of the previous GSM CLIMATE (ZONT H-1). Despite its less attractive appearance, it has an additional “Anti-Freeze” mode and a built-in battery for autonomous operation during power outages. Number of connected temperature sensors – up to 10 pcs.

Otherwise, due to the same firmware, everything is similar to the previous model: the same control via SMS, application or web interface, which, by the way, is one of the most convenient and functional, with statistics. The kit still includes one remote temperature sensor and a remote wired antenna.

Cost: 7,400-9,200 rubles.

Commissioning and management features

When installing the module, the following conditions must be met:

the humidity level in the installation area must correspond to the range specified in the instructions;
if the package does not include a portable antenna, you need to make sure that there are no obstacles to signal transmission (most often it is blocked by a concrete ceiling);
if the cable needs to be moved to another location, it is necessary to provide a small margin of length;
the module is installed to switched off equipment through an RCD - this way the devices will be protected from power surges;
The distance between the controller and sensors should not exceed 100 m, otherwise signal transmission between them may deteriorate.

The first step is to enter the telephone numbers to which the information will be sent; the correctness of the entry is confirmed via SMS verification codes. When purchasing a SIM card for the controller, it is advisable to immediately top up its account with 300-500 rubles and disable the reception of advertising messages so that the latter do not occupy the device’s memory. It is important that there is a stable cellular signal in the area where the module is located.

To test GSM operation, one user stays in the house, the other goes out with the phone: this way you can find out how quickly notifications will be sent when the boiler operating parameters change. Next, set the temperature regime, which will be coordinated by indoor and outdoor sensors. You can set day and night ranges for weekdays and weekends, and introduce energy-saving programs for vacations. All parameters can be general for the house and zonal for each individual room.

If there is a boiler in the system, the intensity of water heating is set; for summer time, modes with minimum power are recommended. For cold months, an anti-freeze program is provided: the boiler is turned on from time to time to ensure the correct functioning of the heating system.

Equipment and functions of the device

Different manufacturers have different equipment packages. The range of functions depends on the device modification.

The standard unit has the following elements:

GSM controller or module. This is a device with many inputs and the ability to connect additional functions. Budget modifications have only a few standard operating modes and functions. An expensive home heating control controller has a built-in control regulator that allows you to set boiler operating parameters for a week in advance.
Portable temperature sensors are installed in different rooms. There are also external sensors. Their number varies from 2 to 10 and depends on the type of module. In an ordinary residential building, five sensors are enough, and one is installed outside the building.
The GSM antenna allows you to strengthen the signal and ensure continuous communication with the user and cellular network towers. To implement feedback with the owner, relays (no more than three pieces) are installed. The device comes with a user manual, which indicates feedback codes, as well as normal and emergency situations.
Some units are additionally equipped with a lithium-ion battery. The duration of independent operation of the equipment depends on this device. In the event of a power outage, the device automatically switches to battery operation. The minimum capacity of this device should be enough for 5 hours of operation of the device. The best option is autonomous operation for up to two days.
The master key is needed to ensure that outsiders cannot interfere with the system. Only with its help you can remove the installed locks.

Depending on needs, users can purchase additional fire or motion sensors, which are also needed in the house during the absence of the owners. The package also includes connecting wires, blocks for connecting to heating equipment, a touch screen, and a device for reading electronic keys.

The device has the following basic functions:

It is used to start and stop the heating system.
Remote control of the boiler. You can turn on, turn off and restart heating equipment, as well as other devices in heating networks.
The user can change the operating parameters of the heating equipment by sending an SMS with a specific code.
The GSM module will regularly send messages to the home owner’s mobile phone with information about the condition of the boiler, emergency situations, operating parameters, and temperature conditions.
If sensors for rapid response to motion, fire or flooding are connected, then notifications about these emergency situations will also be sent. Intelligent systems can shut down equipment themselves due to a gas leak.
Protection against power surges.
Autonomous battery operation in case of power outage.
Increasing the service life of heating equipment by reducing the load on it and timely adjustment of parameters.

There are also additional functions that make using the module much easier:

To install new sensors, other relays can be connected to the device.
You can start additional equipment in the heating system and control its operation remotely using a mobile phone.
In solid fuel heating equipment it is easy to control the pressure.
When using units operating on liquid fuel, you can monitor the amount of diesel fuel in the tank.
In pellet boilers you can determine the quality and calculate the amount of fuel in the compartment.
Additional functions make it easy to check the boiler feeder.
Smart home heating also allows you to turn on the emergency siren.

After installing additional sensors, the GSM module can monitor movement in the room, for example, after it has been hacked. After installing fire sensors, the unit evaluates the smoke content of the room. Installing a leak sensor will ensure that the water supply to the house is quickly shut off in the event of a leak.

Remote controller functionality

The number of functions in any GSM module is limited and is determined by the following factors: the number of channels and, accordingly, sensors that can be connected through them, remote control features, as well as the ability to regulate heating indicators.

Basic and additional options

A standard set of sensors scans temperature, pressure and registers gas leaks; setting additional ones automatically enables new functions. Such sensors can be digital or analog. More often, manufacturers use analog ones, but this depends on the interface of the module itself.

The listed main functions guarantee uninterrupted and stable control of the heating system and implement the operating principles of the device:

Switching the entire heating system on and off.
Possibility to turn on/off, reboot the boiler or additional equipment.
Remotely change the boiler operation settings, temperature intensity in the whole house or in a separate room, simply by sending an SMS with the required code. This will reduce gas consumption to 25-30%.
Daily information via mobile messages about the state of the boiler, namely: notifications about operating parameters, temperature conditions, and, if necessary, about emergency situations, automatic shutdown of the device due to breakdowns.
Using a pin code for the SIM card to avoid connection by third parties and any fraud.
Prompt notification of an emergency shutdown of the heating system due to a fire, leak or any breakdown, if the owner has previously connected additional response sensors for them. The intelligent system, in the event of an emergency, takes steps itself. For example, in the event of a gas leak, the boiler or all equipment is turned off.
Electrical voltage stability control – protection against sudden energy surges.
Autonomous mode of operation of the controller - it is ensured by the presence of a battery. If the power goes out, the module will run on this battery. But remember that when the power is turned off, only the message sending function will work, since the boiler requires continuous current to operate.
By reducing the heating load, the service life of the equipment increases.

Users set in advance the minimum and maximum permissible values of parameters (for example, temperature conditions). When the indicators go beyond the specified range, the owner receives an SMS message about this.

Some modern modifications of GSM modules can display statistics on boiler operation in the form of creating time graphs.

For the convenience of users, the module can “report via SMS” not only to the owner, but also to other family members. You can connect from 2 to 10 numbers, depending on the equipment model

If you are going abroad and roaming is expensive, then you can use one of the other numbers. In some module models, control via voice messages is available.

The functionality, even with standard equipment, is high. As a result, the user will be able to fully control the heating and other systems in his absence.

Additional functions are not fundamental when choosing a module, but they significantly simplify the life of owners:

Possibility to connect an additional relay for new sensors.
Launching additional equipment and the ability to control it using a cell phone from a distance.
Pressure control function in a solid fuel boiler.
Monitoring the level of diesel fuel if the boiler is using liquid fuel.
Calculation of the quantity and quality of pellets in the compartment of a pellet heating unit.
Checking the boiler feeder.
Turn on the emergency siren.

If you install additional sensors, you will be able to perform the following functions:

security of the premises in the presence of motion sensors (can be internal - for the house and external - for the site);
the fire safety function is guaranteed by the smoke indicator - the user specifies the limit numbers in advance;
flood warning - the leakage sensor will give a signal and shut off the water.

It is the various sensors and correct configuration of the module that guarantee that you will know exactly what is happening with all the controlled equipment.

Modes of equipment use

The selected control mode determines when and what information you will receive about the operation of the controlled equipment:

Automatic , in which the system operates according to previously established parameters, analyzing information throughout the house or in individual heated rooms. You receive a report on the heating operation at a specified time.
Manual (feedback from the user to the system) involves the user sending a message with a code word or making a call to change certain settings or modes. For example, you want to know the temperature in a certain room or increase it to warm up the entire house.
Anxious . If there is a power failure, smoke, a leak, gas surges, incorrect operation of equipment (the boiler stops working due to some kind of breakdown), then you will promptly receive a message about the breakdown.

In the latter situation, the module can block the damaged element or turn off the entire system. In addition, during an accident, alarm SMS messages are sent to all previously specified numbers.

All three modes are available in standard modules, but it is important to configure their operation correctly when installing the system.

Advantages and disadvantages of GSM devices

This is what the client will receive by connecting the GSM module:

Safety. The main purpose of the GSM module is to control the heating system and additional equipment, timely informing about existing or possible breakdowns. By connecting, for example, an additional broken glass sensor, you can quickly react if thieves break into your house.

Comfort. Management of key indicators of heating and related systems without the physical presence of the consumer next to them. For example, when returning home, you can easily preheat the water in the boiler to the required levels or increase the temperature in the entire house by sending one message.

Saving. When no one is home, the temperature can be as low as possible, and you will thus reduce your heat bill by a significant amount. And the absence of constant load on the heating system will help extend the life of the boiler, boiler and other equipment.

The diagram shows all the benefits of the module that its owner receives. They are implemented through proper device settings and correct connection. (+)

Thanks to these three advantages, the commercial attractiveness of the module is formed.

And GSM equipment also has its drawbacks. Fundamental, of course, is the high price of the device.

Users note the need to constantly monitor the cash balance of cellular communications, dependence on the operator’s work and coverage. This is especially inconvenient for owners of houses outside the city or in villages remote from metropolitan areas.

Additional disadvantages include: the complexity of self-connection and additional installation costs.

Module connection diagram

The GSM module should be installed at a point from where the necessary sensors and interfaces can be connected using the most optimal route. The following should be taken into account:

The length of the line to the temperature sensor can be from 1 to 100 meters, depending on the functionality of the module.
The communication line with the boiler for control (feedback) should be as short as possible, especially if the module will switch the power supply to the boiler.
There must be cellular coverage at the installation site. As an option, an external antenna is used, then the limitation concerns the cable length.

In any case, the most reasonable thing would be to install it directly next to the boiler. But at a minimum distance of at least 1.5 meters and at a height above 50 cm, so that there is no risk of water entering even in the event of an accident.

The module is connected to the power supply using a separate power line from the panel and terminal block, or simply to the nearest outlet using a wire and plug. The sensors are connected with wires according to the manufacturer's instructions

In this case, it is important to observe the cross-section of the wire and the material from which it is made. Manufacturers often require the use of coaxial cable to connect sensors with full shielding, especially when the remote sensor is located at a considerable distance

The module often contains a set of terminals with symbols under a protective cover. According to the instructions, color or mnemonic markings are used to determine the terminals for connecting sensors, signal and control wires from the heating boiler.

After the wires are connected and placed in a box or protective corrugated pipe, you can begin setting up. The ranges for the sensors are set, the signal lines are set, and the actions that the control device takes when receiving signals are set.

The main point is to set a telephone number or even two to which the module will transmit readings and from which it will receive settings and commands.

ABOUT THE Xital GSM-T LINE

One board, one device, one small device - a special GSM module Xital, which allows remote and automatic access to the heating system, its configuration and control via cellular communications.

It is enough to install Xital once, connect it to the boiler, and it will stably monitor its operation 24/7. It is worth saying that the functionality of the device is not limited to just turning the heating on and off; you also get a number of other features.

Possibility of adjusting air temperature. You set the command to what degree to heat the house and you can be sure that it will be exactly as warm as you wanted. And when you're not at home, save up to 30% on heating costs by simply lowering the temperature of your heating system.

Versatility. Xital controls the temperature of the premises, protects your home, and reports the presence or loss of voltage in the 220 V network.

Monitoring the operating status of heating equipment. If any problems arise, the GSM module will definitely inform you about it.

Design and principle of operation of the GSM module for the boiler

In essence, the GSM module is a variation of a mobile phone, since it uses the same communication protocol.

The operating principle of the device is as follows:

using a SIM card, the device connects to the GSM network;
then it connects to the smartphone;
You can send a signal to the device from the gadget;

The module itself consists of the following structural elements:

Thermostat. Controls the boiler temperature and sends a signal to the owner’s smartphone about its change. Many models allow you to use other notification methods (light, sound signals).
Fasteners Base for mounting the device. Typically designed for installation on a vertical wall.
Power unit. The module elements are not designed to work with standard household voltage. Therefore they need a power supply. Typically the operating voltage of the device is 9 V or 12 V.

Antenna. Allows you to receive signals in the GSM range, with the help of which the module is controlled.
Sensor. Determines the temperature of the boiler and transmits the received information to the thermostat for further processing and notification to the owner. Most sensors are capable of operating at temperatures from -50 o C to +99 o C. This allows them to be used in almost any conditions.
Backup power supply. Represents a battery or accumulator. Designed in case of a power outage or power supply failure. Ensures long-term battery life of the device while maintaining full functionality.

Another essential element of the GSM module for boiler control is the SIM card. After all, it is with the help of it that the device connects to the mobile network. But it will have to be purchased separately. Some manufacturers include a SIM card with a suitable tariff in the kit, but this is rare.

Operating modes

Most existing device models have two operating modes:

Auto. The owner of the device sets the necessary settings, and the device operates in accordance with them. For example, you can set the boiler to turn off when a certain temperature is reached and turn on again after cooling.
Manual. In this case, control is carried out completely manually. A smartphone is used for this.
Anxious. Essentially, this is the same automatic mode. But with one caveat - the system notifies the user in case of emergency situations (for example, an unexpected increase in temperature above permissible values or spontaneous shutdown of the boiler).
