Controlling the temperature in the house. Remote temperature control

The capabilities of devices for remote heating control are becoming more and more advanced every year (and what about the year - almost every month!). Developers of smartphone applications try to make them easy to use and easy to understand, even for untrained people. Let us briefly list only the main capabilities of such systems that support:

normal operating mode, when the set temperature is maintained throughout the house;
zone mode when various rooms there may be an individual temperature;
preventing defrosting of the heating system (freezing of pipes) during the cold season when you are away from your home country house or dachas;
the ability to turn on the boiler in advance, for example, you need to warm up a country house when you plan to visit it on weekends or holidays;
always be aware of your work autonomous heating and, if necessary, diagnose it;
time mode in which different time During the day, the house can maintain its own thermal regime with a significant reduction in material costs for fuel; for example, you can set the boiler to low power (and therefore low fuel consumption) when going to work or on business, and turn on the normal mode before returning.

Remote heating control means that any of these modes, as well as specific room temperature values, are changed using mobile communications, or heating is controlled via the Internet.
This approach is part of the ideology of creating a “smart home”, which entails the further development of all engineering systems of the house in order to ensure ease of use and create the most comfortable living conditions.

Which heating system can be controlled remotely?

In country houses and cottages they are currently most often used two-pipe systems with forced circulation of coolant: the circulation pump pumps coolant throughout the heating system, which, thanks to the distributor comb, can be supplied to each heating device.
In such systems, as a rule, a safety block of the heating system is used to protect it from destruction in unforeseen situations, for example, in the event of an increase in pressure above the permissible level.
It is also necessary to have additional equipment to control the operation of the heating system: sensors, special valves and devices for adjusting coolant flow, and it is also necessary to combine various devices into an information network

Weather-compensated heating control

Today it is considered the most promising. In such systems, in addition to the sensor room temperature An external air temperature meter is also used. In principle, a weather-dependent heating controller will work with one external sensor, but using two allows you to achieve more accurate mode maintenance and even implement self-adaptation of the system to specific temperature changes: if it gets colder outside, then the temperature of the coolant in the system increases in advance, if it gets warmer - then it decreases in advance. In addition to saving fuel, this reduces the inertia of the system, which increases its efficiency and also provides additional cost reduction. One of the basic points of weather-sensitive heating control can be used at a temperature of plus twenty degrees - at which the coolant temperature is taken equal to the ambient temperature, and the heating is actually turned off. It is also necessary to take into account zonal temperature control, i.e. if, for example, a large number of people have gathered in one of the rooms, due to which it has become hotter, then the system detects a local increase in temperature relative to the one set by the weather heating regulator and makes corrections in this zone.
In general, serious battles broke out on the Internet about - Is it worth using weather-sensitive automation at all or is it money thrown away? In short, the opinion of our specialists, confirmed, by the way, by reviews from numerous clients, is unequivocal - yes, it’s worth it, but not in all cases. And in which ones? Answer

Types of remote heating control systems

There are currently two systems in use for remote heating control:

using a set of equipment with an Internet gateway. In this case, a Wi-Fi router and an Internet network are required.
using GSM module heating control. A special GSM module with a cellular operator SIM card is required.

Remote control of the boiler room using mobile GSM

What to do if the wired Internet is in country house No? How can you control the heating in this case?

Yes, it’s very simple - using a special GSM module and, of course, a mobile phone. In fact, the GSM module plays the role of your personal assistant - you called it, gave a command, for example, to heat it hotter by a certain time in advance - and the whole family will arrive in a warm and cozy home. Or, on the contrary, you forgot in the morning, leaving for work, to turn down the boiler power - no question, you can do it right from work, via the Internet or directly from your smartphone while you are still getting to work.
A GSM module is a compact device with its own SIM card from any operator (it is important that it provides reliable signal reception in a given area), allowing you to control the indoor climate from any phone (satellite, mobile or fixed line), tablet or PC.

The undisputed leader in the GSM thermostat market is currently the Russian company MicroLine. The company produces a wide range of GSM modules for remote control heating boilers, including multifunctional controllers that provide control of the most complex heating systems.
You can buy it in the appropriate section on our website. GSM heating control

Depending on the settings made, your phone will receive short SMS notifications with various information and instructions for changing settings heating boiler, or do phone calls with various information about the operation of the heating system. A special mobile application is installed on the phone (there are versions for Android, iOS, and Windows Phone), which allows direct remote control of almost all parameters of the heating boiler.
A GSM heating control module is essentially a computer connected to external sensors and has the ability to change the operating modes of the heating system. Naturally, the module must be located in the area of reliable reception of mobile operators.

The GSM heating control module can operate in several modes:

automatic, when based on signals from installed sensors the controller supports specified modes according to a given program;
SMS heating control, when the heating system is controlled by sending SMS. In this case, when new data arrives, for example about room temperature, the controller accepts it for execution and begins to support it automatically;
warning, by sending alarm messages about the current condition of the house (gas leak, break in the water supply system, etc.);
remote control of other devices connected to the GSM module (watering, lighting, alarm, etc.).

GSM – heating control allows you to remotely:

receive room temperature reports;
receive notifications about the current state of heating equipment;
change the operating mode of the system, increasing or decreasing the temperature, including separately in each room.

Heating control is not limited to these functions. In principle, any heating system can be converted into a remote one. To do this, it must have an automatic operating mode, and a special GSM controller must be connected to it to control the heating and communicate with the subscriber.

Is this not enough for you? Then look at the capabilities of multifunctional GSM controllers, for example: ZONT H-1000 or ZONT H-2000 The devices are complex and require professional knowledge during installation and configuration, so installation requires only highly qualified specialists - contact our company, we have them!

Remote control of the boiler using a set of equipment with an Internet gateway

Now consider the option remote control heating, if the country house or dacha has the Internet and, of course, a Wi-Fi router (also known as a router).
Everything is much simpler here - you can look at the capabilities of the devices proposed below and forever forget about worries about the state of the heating system of your home.

Salus IT500 provides control and adjustment of operating parameters in a maximum of two heating zones, for example, in the 1st room on the first floor of the cottage and the shower room on the second floor.
The kit includes an actuator (boiler receiver), a room 2-channel thermostat (weekly boiler programmer, boiler control panel) and an Internet gateway connected to the Internet router (router).

Possibilities for controlling the heating system using a set of equipment with the Salus iT500 Internet gateway:

control of heating modes only (boiler and, if necessary, pump);
control of multiple heating zones;
control of heating and hot water supply of a country house.
maintaining different temperatures in different rooms, schedule of temperature conditions by day, hour and minute
6 preset heating modes on delivery
heating control hot water, automatic control modes, including energy-saving and vacation mode.
a unique system for connecting devices via the Internet, providing reliable connection and control of the heating system: smartphone (or personal computer) -> Internet server -> router (router) -> thermostat -> receiver -> boiler

All equipment is wireless and communicates with each other via a radio channel, i.e. There is no need for electrical wiring. The room thermostat for the heating boiler is programmed for daily, weekly or 5+2 operating modes. The thermostat screen and remote heating control apps display current status boiler, current and set temperature. Setting the operating schedule can be done from the thermostat panel, through an Internet browser or using a mobile application.
The thermostat has modern design, is highly reliable and safe when used.
Using additional Salus Controls equipment, control is possible, including remote control, warm floors, gas and electric boilers, oil heating systems, as well as almost any other heating systems and devices.

What to do if there is no wired Internet in the house, but you have already purchased a Wi-Fi Internet thermostat?

Most likely, the dacha has coverage from mobile operators, isn’t it? So you also have the Internet! Just buy a Wi-Fi router with a USB port and, in addition to it, a 3G or 4G modem. Install a SIM card from any mobile operator into the modem, providing a reliable signal in the area where your home is located. You insert the modem itself into the USB connector of the router and that’s it - now you have the opportunity to control the heating of your dacha remotely!

If the iT500 seems a little expensive for some, the company offers more budget solution- internet thermostat Salus RT310i
The thermostat has somewhat reduced capabilities compared to its “big brother”, but may turn out to be a worthy replacement for it, thanks to the lower price of the kit. Externally, the RT310i looks more modest compared to the first-class high-tech design of the iT500; it lacks touch controls, but in terms of functionality the models are almost identical. Except that while the iT 500 is capable of controlling 2 zones of heating or cooling, the RT310i can only control one zone.

Missing the iT500's features? No problem - Salus iT600 can do everything and more!

If you do not have enough iT500 functionality to control only two heating zones, then a more functional one is presented on our website multi-zone(there are wired and wireless versions) system Salus iT 600 Smart Home.

Remote control of complex heating systems

All a large share The Polish company Tech Controllers is gaining ground in this market segment, producing a wide range of controllers with remote control capabilities.
The Tech controllers themselves are multifunctional devices that are the main, basic part of the system, which can remotely control almost any complex heating systems using additional modules. There are a lot of possibilities, so using an example we will only consider the possibilities for remote control.

Example of installation of Tech Controllers equipment

In the photo used for installation:
1. Controller Tech ST-409n- a multifunctional device designed to control the central heating system, providing:

Ability to control additional equipment, e.g. garage doors, lighting or sprinkler, etc.

Various Tech modules can be used for remote control, it all depends on the specific needs of the owner. For example:

What to do if the heating system is so individual that none of the above solutions can fully meet the owner’s control needs?
There are no hopeless situations! Most often, the customer himself simply does not understand (and should not!) all the capabilities of modern remote heating control systems. It is really difficult for an untrained person to understand all this abundance of devices offered on the market, which are completely different from each other in functionality, price, and, of course, quality. And installers, often, simply have no idea about the capabilities of controlling heating systems - their task is to install the system, but they don’t care how often you run around the house (or to the boiler room) and turn various valves to ensure constant thermal comfort .

Indoor air monitoring refers to electronic measuring devices that automate the process of monitoring and managing the temperature regime of rooms.

They are included in the structure of the heating system of a house, bathhouse, garage, swimming pool, warehouse or air conditioning system.

Their presence will allow you to remotely control the temperature of the internal environment and, if necessary, regulate it.

What are GSM thermometers used for?

GSM temperature sensor is a measuring device that supports notification of the current temperature and control of executive systems.

A thermometer with a GSM transmitter will inform the owner about the temperature conditions at the facility.

Based on these data, a decision will be made to increase/decrease the supply of coolant to the house. For example, using GSM thermometers Warm House 11, you can remotely set the optimal temperature in your home.

In addition, devices of this kind can be included in systems fire safety. If the temperature goes beyond the maximum permissible limit, the sensor will transmit a warning message to the owner's cell phone, and will also set off an alarm, turn off the heating, activate the fire extinguishing system, or perform another action for which it was programmed during the setup process.

How does a GSM sensor work?

GSM temperature sensors have two modules - a measuring sensor and a transmitting GSM module.

The work of this kind of electronic thermometers is that they measure the temperature and compare it with the limit value (minimum or maximum) that was set in the settings.

If a deviation from the permissible value occurs, a message will be transmitted via GSM communication or a signal will be generated to the actuator.

The alarm signal is transmitted over a cellular communication channel, depending on the specific settings.

This procedure is implemented:

when leaving the established range;
in case of a sharp increase in temperature, which is typical for a fire;
periodically, with a customizable interval;
upon request from a telephone number linked to the GSM sensor.

Depending on the design solution, electronic thermometers can monitor parameters in one zone, as the GSM thermometer Warm House 11 does, or in different areas. This function is available in the GSM thermometer Warm House 22, which has two sensors with independently configurable channels.

Rating of the most popular GSM temperature sensors

Below is information about the five most used electronic sensors with a built-in GSM module.

GSM sensor Polyus Thermo

The device is an electronic thermometer that measures the temperature in a room and compares it with a programmed upper and lower threshold.

When one of the specified values is reached, an alarm signal is sent to the owner's phone number. In total, you can link up to 6 numbers to which alarm SMS and calls will be sent.

The GSM temperature sensor has a built-in sensor that can operate in the range of 0…+50ºС. For measurements in a wider range, an external temperature sensor with a measuring interval of -40ºС…+99ºС is connected.

To transmit messages and calls, a GSM module is used that supports GSM-800/900/1800/1900 standards. The alarm transmission time ranges from 20 to 40 seconds.

Alonio T2 GSM is used to control the air temperature in the house and the availability of electricity in the network that powers the equipment of boiler rooms and air conditioning systems.

If it drops below the set threshold, then the heating system may have broken down, about which a message will be sent to the owner’s cell phone.

An increase in temperature will indicate overheating and possible malfunctions of the air conditioning system, which will also be reported.

An external measuring temperature sensor can be connected to the thermometer, which will allow you to control its value in the range -55ºС…+125ºС.

The built-in transmitter uses the GSM band 0.85, 0.9, 1.8 and 1.9 GHz to send messages. Sending messages about deviations of specified parameters and lack of voltage can be sent to 4 numbers.

This is an electronic meter for remote temperature control, including a GSM module and two sensors - built-in and remote.

The device allows you to continuously monitor the temperature at two points via two independent channels and send warning messages if it goes beyond the established limits.

If necessary, you can find out the current temperature in the house by sending a service SMS to the temperature sensor.

The sensor used is sensitive to the temperature range from -10ºС to +50ºС (internal) and -55ºС…+125ºС (external). The module uses the following cellular communication standards to transmit alarm signals: GSM 2G 0.85, 0.9, 1.80 and 1.90 GHz.

ALFA – TEMPERATURE

This device is used to control the temperature regime at objects with an accuracy of ±0.5ºС.

Humidity measurement is also supported, which will allow you to control the basic parameters of the microclimate of the internal environment.

The electronic thermometer is implemented in the form of a controller that has a measuring unit, the signal from which is processed according to a programmed algorithm and, if it goes beyond the limit values, an alarm message is sent to the owner.

Information can be transferred via GPRS or GSM channel to a mobile phone, to the cloud, to a server.

This GSM thermal sensor supports measurements in the range from -55ºС to +125ºС. For data transmission, 4 GSM frequencies can be used: 0.85/0.9/1.8 or 1.9 GHz.

An electronic thermometer with a built-in battery that monitors the external temperature and the presence of voltage in the network.

Thanks to the use of an autonomous battery, the device will be able to perform its functions even if the main power supply is turned off.

Battery life is up to 2 days.

If the measured parameters differ from the programmed settings, the device will report this using an alarm message sent by the built-in GSM module. The frequencies used for its operation are 0.85, 0.9, 1.8 and 1.9 GHz. Mailing is possible to 4 linked numbers.

Measurements are carried out by two sensors. The built-in one can operate in the range from -10ºС to +50ºС, and the external one – in the range of values from -55ºС to +125ºС.

Conclusion

The use of GSM temperature sensors simplifies the process of monitoring the indoor microclimate when no one is at home.

Thanks to measuring instruments with a GSM transmitter, you can find out about the discrepancy between the temperature regime and the specified values in any place where there is mobile communications coverage.

The presence of reliable data on the microclimate parameters of the internal environment will allow the user to quickly make the right decision in order to eliminate emergency situations and consequences associated with the failure of heating equipment and air conditioning systems.

Video: Review and demonstration of the Alonio T2 GSM thermometer

Until recently, remote control of heating in a dacha was available only to professionals who were able to independently assemble a controller circuit from individual radio components or to those who could pay for such services. However, modern manufacturers have released many models of controllers for smart home systems that perform control functions for various equipment, including heating. Another reason why factory control modules are highly recommended is for fire safety.

Requirements for a temperature control and heating control system

Most often, the heating control system in a dacha is faced with the following tasks:

Firstly, maintenance in the house is minimal required temperature to prevent freezing of the heating system and the building itself;
Secondly, remotely turning on the heating in the dacha before the arrival of the owners, so that by the time of arrival interior spaces warmed up to a comfortable temperature.

To solve the assigned problems, the heating control system must meet the following criteria:

Display information about the current indoor and outdoor temperature after user request;
Send alarm messages if the temperature goes beyond the limit values;
Remotely control the heating system, with the ability to regulate the temperature in the entire house or in its individual rooms using SMS messages or through special mobile applications;
Have an affordable cost, high reliability and ease of management;
Possibility of independent installation and configuration.

The difficulty of developing universal recommendations lies in the fact that very different methods can be used to maintain the temperature in a dacha. The most common ones include: central heating using a gas or electric boiler and radiators, heating with convectors distributed throughout the rooms and traditional stoves or fireplaces.

As a rule, control devices of the GSM alarm system are used as control devices, which have advanced functions and an additional interface for controlling various devices.

Control of central heating boilers

For example, we used the GSM alarm controller Block-Post 4, manufactured by EDS LLC.

This device allows you to control the temperature in 8 zones at a distance of up to 100 from the main device. Although the device is intended primarily for the system alarm system, its latest firmware has extensive capabilities for working with temperature indicators and the corresponding external peripherals:

Range of perceived measurements -40°С…+120°С with an accuracy of half a degree;
There is built-in protection against freezing of the coolant; you just need to indicate which channel receives information from the detector and the limit value. If it is exceeded, an SMS warning is sent;
There is a WEB interface with the ability to maintain statistics and visualize temperature graphs for the period for each temperature sensor;
You can program the maintenance of a given temperature regime and the prevention of freezing of the heating system.

This device has several advantages compared to others regulating the same functionality. First of all, all modules, including the GSM modem and UPS (up to 12 hours of autonomous operation), are built inside the case, which greatly simplifies its installation and configuration. After the SIM card is installed, the controller automatically connects and registers on the developers’ WEB service, which is located at http://monitoring.gsmbps.ru/. Using standard visualization shell tools, you can easily program the device to perform many functions without knowing any programming language. Connection directly to the boiler is made through relay outputs.

In addition, developers are constantly improving both the hardware of the device and firmware, as well as the software on the server. The only limiting factor in the widespread use of BlokPost controllers is that they are quite high price and poor compatibility with devices from other manufacturers.

Convector control - decentralized heating

It is advisable to implement the technical solution using a modular system, since there can be from several to several dozen external controlled devices. As an example, the basic GSM module for building alarm and control systems VM8039D is used. The manufacturer positions this device for security and control of boiler rooms or electric heaters in residential premises.

The device is configured using a special “Configurator” program supplied in the kit. The program interface is quite clear - object-oriented and does not require specific programming knowledge. There is also a mobile control application for smartphones based on Android, called “Home Logic”, which can be downloaded from GooglePlay.

VM8039D can measure temperature in 32 zones, has a built-in thermostat subroutine and is capable of maintaining the set temperature in the room. To use it as a convector control system, additional equipment from the same manufacturer is required:

VM8069D - expansion unit. Temperature sensors, smoke detectors and relays through which the heating system is controlled are directly connected to it;
VM8070 - relay for connecting powerful equipment (electric convectors). It is not recommended to exceed a load of 2 kW per device;
PW1240UPS with NT800 battery - ensures uninterrupted operation of the control system in the event of a power outage.
MA802 - motion detector for alarm system;
SN18B20 - outdoor temperature detector - waterproof;
MP309 - module for measuring values of analog temperature sensors type LM335;
LM335 - analog temperature sensors, range of measured values -40°С…+100°С, measurement accuracy up to 1°С (quite efficient devices at a budget price - up to 1 dollar).
NM18B20 thermal detectors, set of two pieces.

ATTENTION! The VM8069D module has one important operating feature: if it is started without an antenna attached, the device is guaranteed to fail, and there will be no additional device There is no provision for blocking the operation of the device in the absence of an antenna.

The use of universal controllers is justified if, in addition to controlling the heating system, they will also perform other functions: security and fire alarms, control of the irrigation system in the country, remote activation of lighting to create the effect of presence, etc.

How to remotely measure the temperature in a dacha and control heating with special devices

Manufacturers produce a variety of GSM devices, the main specialization of which is remote control of heating devices. The user can choose among many different models:

Gsm-climate zont-h1 is a thermostat for indoor installation with an integrated SIM card. The device is compatible with almost all models of gas boilers that have an input for external control. Control can be carried out from a smartphone, PC, tablet from any operating system. On the manufacturer's website https://zont-online.ru/demo you can download free apps For driving. Changes to basic settings can be password protected. Up to 10 thermal detectors can be connected to the device to determine the temperature inside and outside the building. Setting up the device is quite simple, after installing it in the slot SIM cards An SMS is sent from the user's phone, and subsequently this number receives administrator rights.
Sapsan PRO 5T - the device is a thermostat with 1 temperature detector to which one external electrical device can be connected. The device independently maintains the set temperature range. When the established limits are exceeded, an SMS message is sent to the user. It is possible to configure via a computer. The management utility is included in the kit.
Signal XQ - the device, in addition to the GSM module and temperature sensor, has a built-in battery inside the case, which ensures autonomous operation of the device for 24 hours from the moment of a power outage. Signal XQ sends an alarm SMS in the event of a house blackout, which is no less important than maintaining the temperature, since most modern heating devices volatile. Through the device, you can also organize control of a gas or electric boiler with an external control module.
GSM thermometer “Telemetrics” is a device from a domestic company. It is extremely simple to install and use. Can control two electrical devices by applying voltage to the corresponding relay outputs. Management is implemented through free applications on Android and iOS.

A budget option

There is a very economical solution assigned task. It consists of using GSM sockets. In this case, control is carried out manually through command SMS messages. Examples include the following models:

To control one GSM-Socket T4 device from the Telemetrics company. Remotely controls the boiler through control of the power output. You can set the operating temperature range, time frames (weekly schedule and timer up to 24 hours) or control via SMS messages and mobile applications
To control several devices, it is recommended to use models of the B-DIN-BOX type - GSM controller for 5 machines. This device implements control of each channel separately, as well as general commands for all lines. It is also possible to set a password for each channel.

IMPORTANT! When choosing a specific GSM socket model, pay attention to electrical safety: the quality of the housing, the reliability of the contacts, the presence of grounding, etc. Remember that we are talking about devices with increased fire hazard.

Today we will talk about the possibility of automating the control of heating boilers in a country house. Indeed, today there is no problem to provide remote dispatching of household systems, including heating, ensuring savings and high level comfort.

Goals of remote control

How often does the average resident of a country house approach the heating boiler? If it is a gas or electric unit, then minimal attention is paid to it. Thanks to modern devices automation is possible autonomous operation boiler for a very, very long time. Only in very coldy I want to turn on the light in order to feel this pleasant contrast even more strongly: there is snow and wind outside the window, but the house is warm and cozy. But remote dispatch exists, so what problems does it solve?

To begin with, there are two heating operating modes: economical and comfortable. If the residents of the house are absent for 10-12 hours a day, why maintain the optimal 23 ° C, if you can set the temperature sufficient for safety indoor plants and pets? And if the system operates in a saving mode during the absence of the owners, how to ensure a quick return to rated power so as not to return to a half-cooled house every time? Of course, you can use timing management, but it’s rare that a person can boast of a clear and uniform schedule. So, the first goal of remote heating control is to quickly change the heating power.

Another aspect lies in the stability of the system. No matter how reliable and high-quality boiler equipment is, the probability of an accident is still not zero. A drop in pressure, a stop in circulation, gas leaks - all these phenomena are potentially quite frightening. If the boiler room is left unattended for a long time, then remote dispatch provides its second important function - monitoring the performance of the system and notifying the user of problems. Well, the third function is the ability to remotely troubleshoot or prevent the consequences of an accident.

Type of fuel and operating modes

Electronics provides a huge range of solutions of varying levels of complexity, including those controlled over long distances. However, there is a big difference in what type of heating system you have to deal with; this directly determines the completeness and cost of the equipment.

The easiest way to control electric boilers is that one or more heating elements can be switched by a simple contact or solid-state relay. Additional switching can be used to control forced circulation devices. Neither gas leaks nor attenuation of the solid fuel combustion chamber can occur.

If gas is chosen as the source of energy for heating, the boiler room is classified as a high-risk facility. Backdraft can extinguish the burner, which faulty automation will happily ignore. Remote control will allow you to turn off the gas supply or re-ignite the boiler, and if this is not possible, drain the water from the system to prevent it from freezing.

Solid fuel heating systems are more difficult to manage than others. This requires control automatic feeding fuel, it is extremely important to maintain constant circulation so that the coolant does not boil. But even in this regard, dispatch devices cope with a bang: after all, everything is controlled by electromechanical devices, and it is very easy to interfere with their work remotely.

Electric boilers

Remote control of an electric boiler is one of the most budget projects. Depending on the configuration and operating modes of the system, several options can be offered.

For heating without power control, where the problem of freezing is not relevant, that is, for hydraulic systems with antifreeze, as well as air and convection systems. In such cases, all problems are solved primitively - with a “smart” socket that can receive GSM messages (Brownie, Sokol). The issue price is on average from 300 to 1000 rubles, the difference in cost is due to both differences in quality and switched load, and the availability additional functions. For example, the outlet may have a built-in thermostat or timer, as well as an independent power source. Some models have the ability to connect to mobile devices for easier setup of operating modes. Most products provide feedback to the user; in particular, such sockets can notify about the correct execution of a command or the absence of electricity at the site.

For multi-stage boilers and other heating devices with several active elements, you can use several sockets, but it is better to install one multi-channel (Elgato, Polygator) - the so-called rebooter. These devices are available in a wide range of configurations - both conventional plug multipliers and DIN rail mounting options. The principle of operation is the same: remote control of the load by sending an SMS with an instruction code or a call. Here you can already implement quite interesting operating algorithms, such as turning on an additional heating circuit with a separate thermal control system. It will only be enough to make small changes to the electrical connection diagram of the boiler, connecting individual heating elements to different channels.

Gas boiler houses

Unlike electric gas systems heating systems require remote dispatch not only to receive commands, but also to provide high-quality feedback. Since direct control of a high load is not required, the solutions of the class described above are not entirely applicable. The optimal way out of the situation would be to use a modular switch with 3-4 contact groups, controlled via one of the wired interfaces (RS-232, 1-wire, etc.). Messages can be transmitted both via the GSM channel and through communication with a PC installed at the site. Usually, for the purpose of increased reliability, a main and backup channel are organized.

The price range for gas boiler control systems is incredibly wide. In the lower price segment there are devices from budget “Xitals” for 7-8 thousand rubles to more user-friendly Segnetics for 15-20 thousand rubles. The middle level includes domestic automation complexes OWEN; a set of devices can cost 20-30 thousand rubles. Most complex systems costing more than 50-70 thousand rubles are used in modular boiler rooms common use: on the one hand, dispatch notifies the service organization about the status of the system, on the other hand, users manage at their own discretion in separate parts collector node. Solutions of this kind are not just a set of devices “out of the box”; manufacturers of boiler room equipment such as ROSS and Viessman work in this category, providing the consumer with a comprehensive project and carrying out installation, configuration and maintenance of the system by qualified personnel.

In essence, such devices are ordinary alarm units that have from 6 to 20 control zones and are capable of managing 3-5 groups of dry contacts. There are two popular architectures for such systems. "Xital", for example, are specialized boiler room automation units, which are initially designed to connect standard temperature, gas sensors, smoke and flame detectors. In turn, systems such as Segnetics and ARIES are based on freely programmable controllers, which can be supplemented with communication devices and separate switching units. Their main feature— the ability to connect atypical sensors and control actuators of completely different types.

The main difference between representatives of the latter group is the presence of a convenient user interface: Segnetics is easily configured when connected to a PC or mobile devices, but ARIES complexes require a more serious engineering approach, including writing your own firmware in high-level programming languages. What choice you make for yourself depends on the complexity of the boiler unit and the boiler room piping. Yes, most simple block"Xital" will be sufficient for complete control over the operation of parapet and chimney boilers of low power (up to 40 kW), while OWEN is used in boiler rooms with parallel connection units, or centralized systems air heating and conditioning.

Solid fuel heating control

Freely configurable control systems are optimally suited for solid fuel boilers, as well as installations associated with biogas generation devices. The reason for this is obvious: such boiler houses are initially designed to operate in the presence of an operator and, as a rule, have an individual scheme for setting operating modes.

Thus, for the simplest solid fuel boiler, it is necessary to regulate the inflow and draft, control the temperature of not only the air in the room, but also the coolant at the inlet and outlet of the boiler. Additionally, you should carefully monitor the operation of the circulation system by differentially measuring the pressures at the inlet and outlet of the recirculation unit. Including gas analyzers in the complex will also not be superfluous; in addition, it is worth taking into account the temperature of the combustion products. The secondary function of such dispatch systems can be called ensuring economical fuel consumption and optimal modes its combustion depending on the desired temperature and weather outside the window.

It is important to emphasize that full direct control over each boiler unit will be unnecessary for the average user. Therefore, to control solid fuel heating, complexes of two nodes are used: receiving commands presented by a GSM receiver or Internet router, as well as a software and computing complex, which is configured once and then ensures the correct interpretation of the commands.

Additional complexity is introduced by the variety of actuators. Servo drives are used to control valves and dampers; the performance of smoke exhausters and blower fans and circulation pumps is usually controlled by a frequency converter or PWM. The complex architecture of the system requires ordering not individual automation modules, but a ready-made set of equipment. However, most suppliers of such systems provide this kind of service for a very reasonable price: typical projects cost about 30-40 thousand rubles, including the cost of equipment, but automation of an atypical boiler room with automatic fuel supply can cost more than 50 thousand rubles with a power of up to 100 kW.

Special Features

As a result, we will analyze which functions of dispatch systems are strictly required, what is the logic of the operation of such devices, and what additional capabilities exist. So, when choosing automation with remote control, preference should be given to those products that provide the following functions:

availability of a backup communication channel;
watchdog timer that reboots the system when it freezes;
polling of individual control zones;
remote management of contact groups and a sufficient number of them;
notification of system state changes;
feedback, sending messages about the acceptance and execution of commands.

Additional capabilities of the dispatch module must be determined in accordance with the design features of the heating system. Thus, for liquid heating systems, it is recommended to have protection against leaks: humidity sensors and an electronic pressure gauge capable of recording a prolonged drop in pressure. For open systems heating, it is desirable to control the liquid level in the expansion tank.

Particular attention should be paid to monitoring the operation of forced circulation devices. If the boiler is technically unable to turn off heating when a critical temperature is reached, overheating can only be indicated by the readings of the temperature sensor on the supply pipe, which the control unit receives with a significant delay. In such cases, it is necessary to remotely stop heating by stopping the supply of fuel or air, and if there is a risk of freezing of the coolant, drain it.

For remote monitoring systems, it is preferable to have an automatic response to abnormal sensor readings. For example, the automation itself should adjust the circulation speed depending on the temperature of the coolant in the supply and return, but the user should only receive notifications about critical conditions. In general, we can say that the most important benefit from using the systems we have considered is the timely receipt of information about breakdowns, which allows you not only to take personal part in eliminating the accident as quickly as possible, but also to purchase replacements for faulty components or call a specialist if necessary.

Temperature sensors are used as part of security alarms or systems such as "Smart Home". Their main function is to control the temperature in the room. You should buy a GSM temperature sensor when there is a need to collect information and send it to a central alarm device. In Smart Home systems, the device allows you to find out information about the indoor climate, which affects the automatic switching on or off of electrical appliances. GSM control of the premises, an integral part of which is an alarm system with temperature sensors, allows the owner to save time and money as efficiently as possible. All you need to do is purchase and install a SIM card, and connect the sensor to an electrical outlet.

What are GSM thermometers for?

For remote control of all types of heating devices (electric, gas or solid fuel boilers);
To control heaters (air conditioning, infrared heaters, heated floors and others);
To collect information about air temperature and humidity.

If you believe the reviews of experts about GSM thermometers and alarms with temperature sensors, then we can conclude that temperature control and regulation systems are the most modern ways to control the room climate. This is not only heating or air conditioning, but also the ability to filter air and humidify it.

Why is it worth buying a GSM thermometer and alarm system with temperature sensors?

Possibility to obtain all information about temperature conditions at any time. Most models can be controlled via Android/iOS applications, which makes it possible to collect data in real time and use it;
The device can perform dozens of tasks in automatic or semi-automatic modes, relieving the user of the need to manually control temperature and climate variables;
The price of a GSM temperature sensor seems very low if you take into account all the possible ways to save electricity, water, and gas that can be achieved by using the device;
If the temperature reaches a critical point (which you set yourself), the sensor will notify you by sending an SMS message. In addition, the device can be configured and controlled using SMS commands.
