Automation for heating a private house. Automation of heating systems: how to manage heat flows as efficiently as possible
Automation for heating system control
At present, when there is a constant increase in prices for energy resources, the owners country houses, dachas and cottages are increasingly thinking about the following questions: how to control heating costs by remotely controlling the temperature in their home, thereby reducing their costs for consumed fuel. After all, sometimes in order to achieve a comfortable temperature in the room, for example, when you are going to come to the dacha, it is enough to "flood" a little, and in your absence to reduce the heating power - why throw money away by heating an empty house? With the help of a room thermostat, this is elementary - just set the device to certain temperature parameters that will be observed in automatic mode. But the problem is that you are not at home and you simply cannot go to the boiler or thermostat and adjust the necessary parameters.
What to do, how then to control the heating remotely?
- If the house or cottage is connected to the Internet and there is a Wi-Fi router (router). In this case, there are no special problems - you can buy, for example, an Internet thermostat Salus IT500 or install a more powerful multi-zone system Salus IT600 and close the question.
Articles on the topic of remote control heating:
- If there is no Internet or the quality of its connection is useless, which is very common in areas far from the city summer cottages, then you can use, for example, a special GSM-Climate module ZONT H-1 from Evan or ZONT H-1V from Microline. These are compact devices with their own SIM card of any mobile operator, which provide reliable signal reception in the area and allow you to control the indoor climate from any phone (satellite, mobile or fixed-line), tablet or PC.
The module will only call the owner's phone or trusted numbers defined by him, warning him of all changes or emergencies. Accordingly, the control module can receive commands only from the owner or from "their" phones. Unauthorized access is absolutely excluded - even if someone dialed the number by mistake, the device will ask for a password that only the owner and, for example, other family members or trusted persons know. In addition to SMS control, these devices usually have the ability to control via the voice menu.
In fact, heating remote control modules act as your personal assistant - call him or contact him using a PC or mobile application, gave a command, for example, to heat up hotter in advance, and the whole family, as a result, will arrive in a warm and cozy house. Or vice versa: they forgot to turn down the power in the morning, leaving for work, it’s not a question, you can do it right from work, via the Internet.
With their help, you can control various parameters of the heating system: change the power and mode of operation of the boiler, achieving its greatest efficiency, set the temperature of the coolant, resulting in a comfortable temperature in the room. Moreover, the devices are able to independently monitor the readings of temperature sensors and adjust the operation of the boiler, depending on the pre-set set parameters.
Remote heating control monitors the health of not only the boiler, but the entire heating system! Information is transmitted via mobile communication channels and the Internet. Although, of course, the device is still not a person and cannot cope with an emergency situation on its own. But to notify the owner of the accident in a timely manner, to send a report on changes in the parameters of the boiler or to send a service message - he is always within his power. But in winter, such information is simply priceless, because the bill goes literally for a matter of hours, and if the necessary measures are not taken in a timely manner, then the defrosting of the heating system and the subsequent enormous repair costs are almost guaranteed!

In this article, we will consider the selection of automation for heating systems for individual houses. Typical tasks that the heating system solves are space heating with radiators, maintaining a comfortable temperature in the underfloor heating circuits, cooking hot water.
What is the heating system of an individual building?
Any modern individual housing is equipped with a heat supply system, which, as a rule, includes four components:
- source of thermal energy;
- system radiator heating;
- floor heating system;
- hot water system
Consider the automation of these four systems.
1. Boiler and hot water system
The source of thermal energy for the heat supply of an individual building in most cases is its own boiler, running on gaseous or liquid fuels. Modern boilers are divided into two large groups: single-circuit and double-circuit.
Double-circuit boilers designed for heating and supplying the coolant to the heating circuit, as well as for the preparation of hot water (DHW). The structure of double-circuit boilers includes a heat exchanger for heating hot water, a three-way valve for switching the heating mode / preparing hot water, circulation pump, automation. Hot water is prepared in a flow heat exchanger, so the boiler must have sufficient capacity to cover the peak demand for hot water. To connect a double-circuit boiler, manufacturers recommend installing stopcocks, as well as filters at the inlet to the cold boiler drinking water and coolant from the heating system.
Single-circuit boilers are designed to heat the heating medium of the heating circuit. The composition of the boiler, as a rule, includes a control system and protection of the burner. Circulation pumps and hot water heat exchanger must be installed separately. Often with single-circuit boilers an indirect heating boiler is used, which is a hot water storage tank with a heat exchanger built into it. To supply the coolant to the heating circuit and DHW heating, the DSM-BPU boiler piping pump unit is used.
The heating circuit pump pumps the coolant through the boiler, radiators and (with the help of a mixing unit) through the floor heating kennels. Thermostatic regulators are installed in the heating circuit, which change the resistance of the circuit depending on the temperature in the rooms. To ensure the circulation of the coolant through the boiler in any operating mode, an AVDO bypass valve is provided in the heating circuit of the DSM-BPU pump unit. The AVDO valve can be set to maintain the required minimum flow rate depending on the boiler used. Pump DHW circuit pumps the coolant through the boiler and indirect heating boiler. The resistance of the DHW heating circuit is constant, so no bypass valve is required.
As a rule, the boiler power is selected based on the average heat consumption of the heating and hot water circuit. Peak loads when using hot water are covered by the supply of hot water in the indirect heating boiler. In this case, the boiler works either for the heating circuit, or, if the water temperature in the indirect heating boiler falls below the set value, it switches to hot water heating. This mode of operation is called "DHW priority". Switching heating circuits with the DSM-BPU is very quick and easy: just switch the supply voltage from the heating circuit pump to the DHW heating circuit pump. Check valves installed at the outlet of each pump will ensure the correct direction of the coolant flow. Thus, in order to implement DHW priority, it is enough to connect the pumps of the DSM-BPU unit to the thermostat of the indirect heating boiler or to the boiler control system.
The boiler piping pump assembly includes filters for each circuit, safety valve, faucet to connect expansion tank, stopcocks on each circuit for convenience after-sales service systems. Installation of additional pipeline fittings is not required.
2. Radiator heating
The radiator piping should perform the following main functions: regulate the radiator power depending on the room temperature, shut off the flow of coolant to the radiator for maintenance, repair or replacement, provide the ability to drain the coolant from the radiator during repairs
There are two ways to regulate the power of radiator heating: by controlling all radiators in one room at the same time using a room thermostat or by controlling each radiator independently by a radiator thermostat
A room thermostat is used if the radiators are covered with a decorative grill, in which case the temperature at the radiator installation site differs significantly from the temperature in the room, and the radiator thermostat will not work correctly. Also, if a large number of radiators are installed in the room, it is more convenient to regulate the temperature in the room with one device - a room thermostat. When using a room thermostat, the radiators located in this room are connected to a distribution manifold, on which thermoelectric actuators are located. Actuators open and close the coolant supply to the radiators at the command of the room thermostat. The signal from the room thermostat can be sent by wire (wired version) or as a radio signal (wireless version) to the receiver. For the convenience of connecting thermoelectric actuators, the FH-WC patch panel can be used.
To be able to turn off the radiator and drain the coolant from it, it is necessary to use special shut-off valves, for example RLV-KD for radiators with bottom connection or 2 pcs. RLV for radiators with side connection. These valves can be connected to a drain cock with a nozzle for a 3/4" hose and prevent the coolant from entering the finishing materials during maintenance and repair
Drain valve for valves RLV, RLV-KD with nozzle for 3/4" hose
When using radiator thermostats, each radiator must be fitted with a thermostatic element, thermostatic valve and stop valve, or a combination of these elements
According to the type of connection, radiators are divided into radiators with side connection and radiators with bottom connection.
Consider options for piping radiators with side connection.
a) Thermostatic element, thermostatic valve and shut-off valveAs a thermostatic element, the bellows gas-filled element RA2994 or the living eco electronic thermostat can be used.

Chrome-plated versions and press-fit versions are also available, see below.
b) Thermostatic element, side connection fitting RA-K
The headset combines a thermostatic valve and a shut-off valve. The use of a headset allows you to lower the plastic pipelines below the level of the radiator and thus prevent sunlight from falling on them, which causes premature aging of the plastic pipelines. In addition, the headsets look very aesthetically pleasing and simplify installation.
The RA-K set is compatible with RA2994 and living eco thermostatic elements. Depending on the method of laying pipelines, a headset with a bottom or rear connection of pipelines should be selected.

c) Thermostatic element, fitting for lateral single connection RA 15/6TB
The RA 15/6TB set is compatible with RA2994 and living eco thermostatic elements. This headset allows you to hide the radiator piping as much as possible. It should be borne in mind that a single connection reduces the heat transfer of the radiator by 15 ... 20%.
Consider the options for piping radiators with a bottom connection
a) Radiator with bottom connection without built-in thermostatic valve In this case, a VHS headset and a thermostatic element should be used. As a thermostatic element, the RA2994 bellows gas-filled element or the living eco electronic thermostat can be used.
Depending on the piping layout, a straight or angled VHS version is used, and depending on the connection to the radiator, a G 1/2” or G 3/4” version.

Direct VHS Headset
b) Bottom connection radiator with built-in thermostatic valve with RA clip connection
In this case, the bellows gas-filled thermostatic element RA2994 or the living eco electronic thermostat should be used. As shut-off valve valve RLV-KD can be used. Depending on the piping layout, the straight or angle version RLV-KD is used, and depending on the connection to the radiator, the G 3/4” version or with G 1/2” adapters is used.
Straight shut-off valve RLV-KD with adapters G 1/2”
Angle stop valve RLV-KD with adapters G 1/2”
c) Radiator with bottom connection with built-in thermostatic valve with threaded connection M30x1.5
In this case, the RAW-K thermostatic element or the living eco electronic thermostat with K adapter should be used. The RLV-KD valve can be used as a shut-off valve. Depending on the piping layout, the straight or angle version RLV-KD is used, and depending on the connection to the radiator, the G 3/4” version or with G 1/2” adapters is used.

3. Floor heating
The heat-insulated floor provides special comfort in the room. With sufficient insulation, underfloor heating can provide compensation for heat loss, but in practice, as a rule, an underfloor heating system is installed in addition to radiator heating.
Radiators and underfloor heating require different coolant temperatures. The classic parameters for radiators are 80 C for supply and 60 C for return. For comfortable and safe living, the average temperature of the floor surface should not exceed +26 C for rooms with permanent residence of people, this value is regulated by the Code of Rules SP60.13330.2012 (updated version of SNiP 41-01). To achieve such a floor surface temperature, the temperature of the supplied coolant should be about 40 C. In order for the floor surface temperature to be uniform, the temperature of the returned coolant should differ from the supply temperature by no more than 5 ... 10 C. To obtain such parameters of the warm floor coolant, mixing units are used.
The modern world can not do without innovative technologies for a long time. There is not a single technology or system in which revolutionary solutions have not been applied. The heating system is no exception. This is due to the fact that this is quite a significant technology, which is designed to provide a comfortable existence.
For obvious reasons, when designing a house, special attention is paid. Since ancient times, houses were built from the stove, that is, the stove was first built, and then it was overgrown with walls and ceiling. This was done for a reason, for this we need to say “thank you” to our climate.
Starting from the middle zone of our spacious country and ending with distant Sakhalin, most The temperature is rather uncomfortable. The thermometer ranges from +30 to -50 degrees.
Due to the rather complex temperature resonance, the heating system is just as important as the electricity supply. Previously, a competent stove-maker who knew how to make the right stove was valued at the level of a blacksmith. After all, you need to correctly calculate the size of the furnace, the diameter of the chimney, besides, the furnace had to be multifunctional:
- food was cooked in it;
- she heated the room;
- warmed up the water
- served as a small bed.
That is why the construction of the furnace was a difficult and time-consuming task. She had to have enough thrust so that all the products of combustion did not enter the room. But with all this, it had to be economical.
Today, little has changed fundamentally. The main functions and requirements for the heating system remain the same:
- saving;
- maximum efficiency;
- multifunctionality;
- simplicity of design;
- quality and durability;
- minimal operating costs;
- safety.
Fire was the first source of heat for man. And even now its relevance has not lost its significance. The most primitive way of heating was to build a fire, which gave protection from predators, low temperatures served as a source of light.
Further, over time, humanity began to tame the gift of Hermes. Furnaces appeared, they were usually built of clay and stones. Later, with the progress of technology, ceramic bricks began to be used. And that's when the first ones appeared.
Steel furnaces appeared much later, they determined the formation of the steel age. The fuel for the stoves was coal, firewood, peat. With the gasification of cities, furnaces have become. And all this time, man sought to improve the heating system.
Structure
In order to define and compose the main functions and tasks, you will need to understand the structure and principle of operation of the heating system itself.
Closed heating systems are widely used. They usually consist of one or two closed loops. There are also more complex systems. The composition of the heated house includes:
- boiler;
- boiler;
- pipelines;
- controls;
- sensors and control relays;
- backup heat sources.
Each node is responsible for its functions and all of them together form a heating system.
Knots
The boiler is the heart of the system. It converts either electrical energy or hydrocarbon fuel into thermal energy. It is in his competence to heat up the coolant in order to transfer heat through it to its destination.
There are boilers according to the fuel consumed:
Gas heating in the house
- gas boilers;
- boilers for liquid fuel (diesel fuel or kerosene).
Boilers must be installed in a well-ventilated area. In the case of gas fuel, there must be a connection project, and it must be under the control of the sponsored gas service.
Boilers do not require a certain supply of flammable liquid for full operation. The most economical boiler is a gas boiler.
Boiler - performs the tasks of heating water, which gets into the taps and faucets through the plumbing. Since the main coolant circulates in a closed system and is of poor quality, and in recent times instead of water, antifreeze is used as a coolant, so warm water does not go directly through the boiler. It is heated in a special tank, which is connected to the boiler.
Thus, pure water does not mix with process water in any way. Heating occurs through the walls of pipelines that encircle the internal contour of the tank. In the collection, this tank is the boiler.
Circulation pumps are designed to create a directed movement of the coolant through pipelines. The advent of pumps led to the emergence of an increasingly sophisticated heating system. Houses became multi-storey, there was more than one circuit, and the natural (convection) flow of water through pipelines became inefficient.
With the use of circulation pumps, the distribution of heat throughout the rooms has become much better, the diameter of the pipelines has significantly decreased. In addition, when using a warm floor with liquid heating, the installation of a circulation pump becomes vital.
Pipelines serve as overpasses for the fluid that transfers heat from the source to the consumer. They must withstand high temperatures up to 80 degrees, and at the same time must withstand the pressure created by the pumps. Their walls are required for a long time to create a minimum resistance to the current of the coolant, thereby saving on electricity. After all, pumps run on electricity.
Radiators close the technological process for space heating. They dissipate heat through it, which came from the boiler with the coolant.
The heating system must be backed up. In case of failure of the boiler, for the period of its repair or replacement, there must be a backup source of heat. It should prevent the cooling of the whole house.
Purpose of heating automation
Many manufacturers unanimously say that their automation allows you to save energy, whether it be gas, diesel fuel or electricity. This is a little different. Of course, there is a savings factor, but the system itself was designed primarily to maintain the microclimate in the house.
The principle of operation of the system depends on the temperature environment and indoor temperature. Information on the lower and upper temperature limits is entered into the system in advance. In case of deviations, the automation decides to turn on or off the heat sources.
The control is carried out by thermometers. Data from these sensors enters the control unit, which analyzes many parameters. Modern automatic systems able to regulate the daily air temperature.
Control and management is carried out for all nodes in the heating system. When the temperature in the room falls beyond the minimum limits, temperature sensors record this process.
According to the programmed program, the boiler is started, when the boiler is heated to the desired temperature, the circulation pump is turned on. After a short time, the entire heating system of the house is heated to operating temperatures and the heating field of the house, the system goes into either sleep mode or keep warm mode.
Any modern automation allows you to work:
Home systems management automation system
- in manual mode;
- in automatic mode;
- in remote control mode.
With the first two modes of operation of the system, everything is clear, but here remote mode is a revolutionary solution that has become available quite recently. With the introduction of the GSM module, the exchange of information wirelessly became available. Now, thanks to the GSM channel, the following features have become available:
- remote monitoring of the state of your home;
- control of the heating system through mobile devices;
- receiving signals from the system to you about the occurrence of emergencies.
Summary
Thanks to the automated system, living in a private house that is not connected to a central heating system has become much more comfortable and safer. And thanks to remote monitoring and control, it became possible to leave the home unattended. In addition, automation will soon pay off due to energy savings.
For modern man one of the most important components of comfort in the premises where he lives or works is a stable air temperature. To maintain it, various automation tools are being introduced into modern climate systems, which, in heating systems, are simultaneously able to provide tangible savings in energy costs. This article introduces readers to the benefits automated systems heating and ways to improve their energy efficiency, with the necessary technical requirements to individual components of heating equipment, and also contains recommendations for their selection.
Purpose and benefits of automation
Automated heating systems are designed to maintain a microclimate in buildings and premises that is most comfortable for work and leisure. In addition, due to the ability to use energy resources more rationally, such systems are much more efficient than traditional ones.
The setting of a comfortable temperature in the premises is provided by thermostats or temperature sensors that constantly monitor its changes and allow the heating system to take into account all the current factors affecting the temperature in the room: human heat, solar heat, heating from lighting devices, radiation from other electrical appliances, etc.
If the means of automatic control of the supply of heat carrier are used directly in the heating point of the building, which monitor the temperature of the outside air, then this saves about 15-20% in energy consumption. The use of thermostatic valves on heating radiators further reduces energy consumption by another 5-7%.
Automation also allows you to flexibly change the temperature regime in the premises at different times of the day. During transitional calendar periods (autumn/spring), characterized by temperature instability, the automated system will reduce heat supply during those hours/days when the air temperature rises significantly.
If the heating system is equipped with GSM modules, then this makes it possible to monitor the thermal regime of the building / room remotely, for example, using mobile devices.
An effective way to save energy is to use automation devices that allow you to maintain different day and night temperatures in the premises. So, in non-residential premises, you can lower the temperature at night, and during the day - set it exactly at a comfortable level, but not higher. This is important, since an increase in temperature by just one extra degree leads to an increase in energy consumption by 5-7%.
You can also save heat in residential areas. Automation with a timer-programmer, in accordance with the individual needs of the user, will regulate the heating temperature and the operating time of the heating system in a given mode. While the residents are at home, the system will maintain a comfortable temperature, and when they are at work, study, away, etc. - switches to economy mode and provides the minimum required temperature (for example, for plants or pets).
The use of energy-efficient technologies such as heat pumps and condensing steam boilers is also a significant savings in the operation of heating systems.
Types of automation devices
To change the temperature in heating systems, two-position control devices (thermostats) and smooth control devices (temperature sensors) are used.
Thermostats are used to maintain a constant set temperature in the room. They work on the principle of turning off the heating of the boiler of the heating system when the desired temperature is reached and, accordingly, switching on when the temperature drops below the set level. These are the simplest and most reliable devices for indoor climate control. Thermostats provide a sufficiently high level of comfort and fuel savings of up to 20%. They are ideal for use in separate heating of apartments and other small spaces.
Smooth control devices - temperature sensors - allow you to maintain the temperature in the room at a given level, regardless of temperature changes outside, as well as reduce energy consumption. They are connected to the steam boiler system and transmit temperature values to it, according to which the automation independently selects the required temperature of the coolant. Temperature sensors are more accurate than thermostats, and thanks to the timer function with a remote control and programming module, they are also able to provide elevated level indoor comfort and energy savings.
Requirements for radiators for automated heating systems
Effective operation of automated heating systems is impossible without the use of heating radiators, which have a number of necessary properties. Firstly, such radiators must have low thermal inertia, i.e. heat up and cool down quickly, which will allow automation to flexibly control temperature regime in room. Secondly, radiators must have high heat transfer, which makes it possible to use relatively small volumes of heat-transfer fluid in the heating system. As a result, an additional reduction in the inertia of the system, as well as an increase in its energy efficiency.
Radiator material selection
Among the radiators on the market, only those that are completely made of aluminum alloys meet the above requirements. Of all the materials used in the production of radiators, aluminum has the lowest thermal inertia and the highest heat transfer with a low specific weight. In addition, its high manufacturability (simplicity of fabrication of structures with a large area of fins) makes it possible to additionally and significantly increase the heat transfer of finished radiators.
Bimetallic and steel screen radiators, slightly inferior to aluminum ones in heat transfer, lose because of their greater thermal inertia and greater specific gravity (difficult to install). Cast iron radiators lag even further behind in these two indicators. In addition, it is much more difficult to make a durable and compact structure with a large number of fins from this material, and traditional cast iron radiators are absolute "anti-record holders".
To the already listed advantages of aluminum radiators, one should add ease of installation (light weight of structures) and affordable prices(aluminum is a widely used and easy-to-work metal).
Aluminum radiators Global
So, aluminum radiators- the only one right choice for automated heating systems. But are they all equally suitable for this purpose? Our answer is no. The fact is that the Russian market is flooded with cheap products from the Asian region, which have a number of shortcomings that do not allow them to be recommended for building reliable heating systems.
First of all, it is worth mentioning that in many Chinese factories, in the production of radiators, such stability is not ensured. important characteristic like heat dissipation. In addition, in the data sheet, this figure is often overestimated, which leads to errors in the calculations of heating systems. The second serious problem is the insufficient strength and reliability of the design of radiators manufactured in small factories without a well-functioning quality control system. An important role in ensuring the durability of radiators is played by their corrosion protection inside and high-quality painting outside. But even these means are often neglected by Asian manufacturers in order to reduce the cost of production.
To avoid unpleasant surprises during operation, for heating systems, you should choose the products of large companies that have proven themselves well in the domestic market and have an extensive network of official trading partners. One of these companies is the Italian Global, which has been manufacturing heating radiators since the 1970s and has been present on the Russian and CIS markets for more than 20 years. High-tech production and its own research base of this company are a guarantee of reliability and durability of products. In addition, the use of only high-quality certified aluminum alloy in production provides such an additional advantage of Global radiators over competitors, as more high heat transfer at low coolant temperature. This becomes especially relevant when using heat pumps and condensing steam boilers in the heating system.
conclusions
The heating system is one of the most important components of maintaining necessary conditions domestic life or work, especially in harsh Russian climatic conditions. A well-designed and built system will provide not only the necessary level of comfort, but also serious savings in the long run. Therefore, it makes no sense to save on any components, whether it be heat generation equipment, control automation tools or end devices - heating radiators. The greatest effect can be achieved and can be maintained for a long time only if the balance is maintained.
Autonomous heating is an urgent need for owners of country houses who do not have the ability to connect to the highway. Like any piece of equipment, it needs to be fine-tuned to achieve maximum operational efficiency. Modern technologies allow you to install the heating control unit of a private house remotely, using a cell phone, the Internet and other communication methods. This approach makes it possible to receive timely notifications of an emergency, remotely issue commands to turn off the system, adjust the temperature by sending messages in accordance with your own requirements.
The main detail in the whole scheme is an electronic control unit, which provides slots for installing standard SIM cards for cellular communication. More technological modifications also have a connector where an electronic Internet cable is connected. Similarly, temperature sensors, pressure indicators, fire alarms and other security systems are connected to this module. Of course, to ensure feedback and the unit itself must be connected to the heating boiler.
Heating control country house carried out according to a simple, in general, scheme. The initial adjustment of the functioning is carried out, after which the central processor fixes in the memory the correct operating conditions of the system. If one of the connected sensors sends a signal about a change in these conditions, for example, the temperature starts to drop, a text message is sent to cellular telephone owner. The owner, in turn, can request the readings of other sensors in order to more fully assess the situation, send a response command with a text message to turn off the devices or continue working as usual.
The heating control system can also be based on communication through the use of the Internet. To do this, on a cell phone with access to the global network, you must first install a special application that demonstrates all the current system parameters in real time.
Tangible benefits
Consider a few situations in which the scheme is guaranteed to be useful:
- You return to the cottage from a week-long business trip or vacation, during all this time no one lived there. On the way from the airport, you send a text message, send a signal to start heating. By your arrival, the microclimate in all rooms will be as comfortable and pleasant as possible.
- You set the boiler to an economical mode, which excludes freezing of the coolant in the pipes, and leave. Unexpectedly, a failure occurs, the coolant cools rapidly, the module detects an accident, sends you a message. You, in turn, send a response command to restart the boiler. If this measure does not bring results, it is worth calling the emergency service. This method eliminates the possibility of freezing of the coolant in the pipes, which will inevitably lead to a rupture and huge financial costs for restoration.
- If you want to know the current situation in the house, send the appropriate command. The response message contains information about the air temperature in the controlled premises, the level of humidity, and the current temperature of the system coolant.
- arose dangerous situation with a gas boiler: the fuel supply circuit is depressurized, there is a high concentration of the composition. reply message heating system is transferred to a backup power source, the problem is eliminated by specialized services.
Set of modules and installation features
Heating control in country house according to the GSM standard, it assumes the presence of the following elements:
- A unit equipped with slots for installing cellular cards and power cables.
- Auxiliary remote antenna that improves signal quality.
- An integrated battery that maintains the device's performance when the centralized power supply is turned off. Please note that with autonomous power, functionality decreases significantly. For example, the unit will not be able to signal a restart gas boiler, for this there is simply not enough voltage. The built-in battery should last approximately 3 days of operation. Many models require the connection of an additional power source.
- temperature sensors. In most cases, their maximum number is limited to five.
- Additional sensors for security and fire alarms, water supply breakthroughs, unauthorized opening of windows and doors.
Thus, not just a heating control system, but a full-fledged security complex can be formed in the house.
If we talk about the nuances of installation, then there are no particular difficulties. All devices are fixed as easily as possible. To eliminate the possibility of failure, we recommend mounting the control unit in a room where the most stable and clear cellular network signal is recorded. It is also worth contacting the operator so that advertising messages from unknown numbers do not come to the SIM card in the block, such interference often causes failures.
Functionality
The minimum set of functions that control and configure the heating system high-rise building, is as follows:
- Setting the air temperature in the premises and the temperature of the coolant;
- Formation of a text report indicating all operating parameters and further sending to the owner's phone;
- Determination of voltage stability in the home power network;
- Control of devices in case of an emergency, including emergency shutdown of the boiler;
- Maintaining the temperature in the premises at a given level, its remote adjustment.
Additional functionality depends on the exact model of the automation unit, a set of connected sensors. Practice shows that the following functions are most useful:
- Control over pressure and fuel level in diesel and wood-burning devices;
- Tracking unauthorized access;
- Activation of a fire alarm in the event of an open fire, smoke, a sharp increase in temperature;
- Leak tracking.
Please note that some blocks involve communication not with one number, but with nine at once, they are designed for storey buildings.
Summarize
It turns out that the automation of the heating system is a profitable and justified solution from all sides. The efficiency of operation increases, the risk of an emergency situation is eliminated, the comfort of living reaches maximum level. With all these advantages, the cost of setting up such a system is democratic, the devices will pay off in just a season or two!
