Household heating appliances operating on liquefied or natural gas, do not require constant attention and control from the owners. This task is performed by automation for gas heating boilers.

Electronic and mechanical control units integrated into the heat generator regulate combustion and help maintain the required temperature in the coolant.

The automation works properly, accurately and reliably, increases the efficiency of heating equipment, promotes reasonable consumption of energy resources and makes the operation of the heating system simple, comfortable and absolutely safe.

The automatic system protects heating installations from overloads and activates emergency shutdown of gas supply in case of sudden force majeure circumstances. Additionally, the equipment regulates the level of combustion intensity and current fuel consumption, allowing owners to save money on heating the premises.

The automatic unit has flexible settings and allows the owner to set the most convenient operating parameters for the equipment.

By basic principle operation and design features, automation for gas-powered equipment is divided into:

• energy dependent devices;
• energy-independent devices.

Systems of the first type are complex electronic units that require an uninterrupted electrical supply to operate correctly. The second types of devices are simplified mechanical structures that do not require energy supply.

Type #1 - volatile products

Volatile module is a small electronic device that responds to the supply of fuel. Turns on and off when the main one is activated or closed gas tap. Is different complex design and a large number of elements and microcircuits.

Allows owners to solve the following tasks:

• activation or termination of gas supply;
• starting the heating system in automatic mode;
• adjusting the power level of the base burner (due to the presence of a thermostat);
• turning off a running boiler both in emergency situations and within a user-specified mode;
• displaying current indicators on the display (the general level of air temperature in the room, the point to which the working coolant has been heated, etc.).

More sophisticated modules have additional functionality and offer users unlimited and most convenient conditions for monitoring the operation and control of the unit. Electronic panels provide complete protection of heating equipment from malfunctions and prevent the boiler from freezing.

If the temperature in the room drops sharply, the “smart” system itself starts the heating equipment and turns it off when the home is filled with comfortable warm air.

The self-diagnosis option available for individual modules prevents operational failures and facilitates the timely identification of faulty parts and assemblies in the system. It makes it possible to notice a breakdown as early as possible and replace some small element even before it creates a real problem for the equipment.

Minor breakdowns of the heating system eventually turn into global complications and entail costs associated with the repair and dismantling (full or partial) of the equipment. Self-diagnosis helps to identify a malfunction and makes it possible to eliminate it in a timely manner.

Electronic automation responsible for safe operation equipment, provides uninterrupted operation boiler, prevents the system from overheating and shuts off the gas supply in the event of a drop in draft or extinguishment of the flame in the burner.

The range of energy-dependent automation on the market today is pleasingly diverse. Useful and necessary mini-units are produced by world-famous brands and small companies, just trying to win their place in the sun.

Volatile automation is presented in the form of a control panel, where the user can set convenient operating parameters for the equipment. The cost of a “smart” element is high, but the costs are justified, because with the help of a control unit you can reduce resource consumption without any damage to your own comfort

Among the models offered there are both very simple products and more advanced units with a programming option.

On them, the user can choose the ones most suitable for himself and program the system to operate in day/night mode or, based on the weather forecast, set a certain level of heating of the house or apartment for a period of 1 to 7 days.

Type #2 - non-volatile units

Non-volatile automation more simple and practical. Control and adjustment are carried out manually using mechanical rotary toggle switches and are not difficult even for those who are far from technology. The device operates completely autonomously and does not need to be connected to a central electrical system.

To heat a residential building and supply hot water to the taps, it is enough to turn the control knob in the direction of increase by 2-3 divisions. If you need to take a bath or shower, the toggle switch must be set to the maximum setting

The product is marked with a digital scale with a list of values ​​from minimum to maximum. To activate, the user selects the desired mark and in this way sets the appropriate operating temperature directly to the boiler.

After these manipulations, it connects and takes control of the specified heating mode. The boiler actively works until the room warms up to the desired temperature. Then the thermostat turns off the gas supply to the system and is activated again only when the room gets colder.

The operating principle is based on the specific design of the device. Thermocouple built into the heat exchanger gas boiler equipped with a special rod. It is made from a special iron-nickel alloy called invar.

The physical characteristics of this advanced material give it the ability to almost instantly capture minimal temperature fluctuations.

If the room becomes too hot or too cold, the size of the rod changes. The connecting valve reacts to this and promptly shuts off or activates the flow of gas to the burner.

The presence of a non-volatile automatic control system allows users to set the most suitable temperature regime in their house or apartment and use fuel economically without overpaying on utility bills

Additionally, non-volatile type automation has sensitive ones. If the pressure in the pipe suddenly decreases or the draft level in the chimney drops for some reason, the supply of the resource is immediately stopped and gas leakage can be avoided.

Non-volatile automation costs quite reasonable money and, unlike electronic analogues, does not require the purchase and installation of a stabilizer that controls voltage and equalizes unexpected surges in the central power grid

Correct operation of the flame sensor is ensured by a special plate. Under normal and proper functioning system, it is in a slightly curved state.

In this way, the part holds the shutoff valve in the “ Open" When the flame becomes smaller, the plate is leveled and the valve closes under its pressure.

Design and operating principle

The automation that controls the work consists of many elements, conditionally divided into two subgroups. The first includes mechanisms that ensure the full and safe functioning of the boiler itself. The second includes devices that make it possible to operate the heating system in the most convenient and user-friendly mode.

Components of a security system

Several modules are responsible for the operational safety of the unit:

1. Flame controller– consists of two main parts – a solenoid valve and a thermocouple. Shuts off gas promptly and reliably and prevents leakage.
2. Thermostat– maintains the set coolant temperature and protects the system from overheating. When the coolant cools down to minimum temperatures, the module starts the boiler into operation, and after recording peak-high readings, it turns it off, completely relieving the owners of the need to constantly pay attention to the system.
3. Traction control sensor, is responsible for stopping the gas supply to the burner in the event of a change in the basic position of the bimetallic plate, thus preventing gas leakage.
4. Safety valve– monitors the amount of coolant in the circuit.

In addition to all of the above useful qualities, automation has a number additional functions, increasing the comfort of using the equipment.

The device performs auto-ignition gas burner, selects the most effective operating mode, promotes rational consumption of energy resources and conducts independent diagnostics, saving owners from all these activities.

Operating principle of security automation

Current normative documents says that the safety complex of gas boilers must be equipped with a device that stops the operation of the entire system and cuts off the gas supply in the event of an unexpected breakdown or any other force majeure circumstances.

To carry out this task, automation must keep under control such parameters as:

• gas pressure in the system;
• presence of an optimal size flame in the burner;
• full, high-quality traction;
• working coolant temperature level.

When in a non-volatile mechanical system the gas pressure drops to a critical level, the resource supply immediately stops. This happens automatically due to the presence of a valve mechanism set to a certain value.

Volatile electronic devices are designed slightly differently. In them, the above function is performed by a minimum/maximum pressure switch.

As the number of atmospheres increases, the membrane with the rod bends, opening the power contacts of the boiler itself. Gas stops flowing and is not supplied until the pressure level is restored.

It is prohibited by law to independently troubleshoot problems and somehow interfere with the basic functionality of the equipment. Only a qualified specialist - an employee of the gas supply company - can correct any problems that arise.

If the flame disappears in the burner, the thermocouple cools down and stops producing current. After this, the electromagnetic damper in the valve no longer functions and gas stops flowing to the burner. When the thrust drops, the bimetallic plate heats up intensely, changes shape and acts on the valve, causing it to stop supplying fuel.

The coolant temperature is kept under control by a thermostat. It ensures that the user-selected heating mode is maintained, while preventing the system from overheating and failing.

Nuances of the system's functioning

Volatile electronic automation operates based on information received from sensors. The microprocessor and internal controller analyze this data, process it and provide the system with commands that are optimally suited for a particular situation.

In order for electronic automation to function normally for a long time, it is necessary to call a technician annually to inspect the equipment, diagnose the microprocessor and view memory module reports

Mechanics have a slightly different principle. When the boiler is turned off, the internal gas valve is completely closed. At the moment the equipment is started, the washer on the valve is squeezed out and the passage for the fuel resource to the igniter is forced to open. Ignition stimulates heating of the thermocouple and voltage is generated across it.

This resource uses an electromagnet to support the valve in open position. By turning the washer manually, the user can effortlessly adjust the level and power of his heating equipment.

Review of popular models and manufacturers

In the progressive market gas equipment and accompanying elements, automation of both domestic and foreign manufacturers. According to the principle of operation, all devices are absolutely identical, but in terms of design there are significant differences between them.

Availability of control automation in the system gas heating makes it possible to comfortably heat the room and rationally use energy resources. With a reasonable approach, savings can range from 30 to 43%

The cost of modules varies in the widest range. Simple mechanical products with a minimum of functions belong to the budget class and are sold at the lowest price. Advanced electronic panels are valued much higher, but provide the user with more extensive options for individual settings and control of work.

Do you know the intricacies of gas equipment automation that are not mentioned in the article? Did you have any questions while reading the material? Please write comments, share your own opinions and photographs on the topic of the article.

When considering options for heating a home, they most often choose to use a gas boiler. If there is a main gas pipeline near the house, this heating option is considered the most economical and efficient.

When installing any heating boiler, including gas, automation is a mandatory component of the system. Such automation for heating boilers allows, without human intervention, to maintain the specified climatic conditions in the heated room and ensure optimal conditions operation of such a boiler.

What does automation for gas heating boilers consist of?

Typically, such automation includes the following elements:

• fittings These are actuators that, under the influence of commands, turn the boiler on and off, and also regulate its power;
• valves designed to shut off the gas supply;
• maximum and minimum pressure switch. Designed to protect the system when pressure drops or increases too much;
• thermostat;
• water and gas pressure sensors;
• controller – electronic device, which calculates the optimal operating mode of the gas boiler from the received data and generates control commands.

Types of automation for heating boilers

From a power supply point of view, there are two types of automatics for gas boilers:

• non-volatile automation;
• volatile automation.

These two types of automation differ in that the first system does not require power from electrical network, and for the second one to work, electricity must be supplied

Accordingly, these two automation systems will include different elements.

Non-volatile automation is simpler and more reliable, as it does not react to a sudden power outage.

Non-volatile automation

Such automation systems include:

• ignition system, which uses a piezoelectric element;
• thermostat;
• draft and flame sensor.

Mechanical automation begins to work after starting the boiler. Depending on the temperature of the heated water, the thermostat changes the amount of fuel supplied to the burner. Structurally, the thermostat is a metal rod. It changes its length with temperature changes. Thus, it opens or closes the gas supply.

The draft and flame sensor is designed to interrupt the gas supply when the burner flame goes out or there is poor draft in the chimney. Structurally, such a sensor consists of a bimetallic plate, which, under the influence of temperature, changes its position and closes the gas supply.

The control and measuring equipment used in such systems is a pressure gauge and a thermometer. This system is configured manually.

Modern non-volatile automation systems for gas boilers can have much larger number nodes For example, Italian non-volatile automation has the following components:

• temperature switching and control system;
• flame protection system;
• setting device minimum flow gas;
• pressure regulator;
• thermostat with burner shut-off function.

Volatile automation

Volatile automation is more complex. Such an electronic system includes a larger number of elements.

For regulation in volatile automation, electromagnetic valves are used. The operation of these valves is carried out according to commands generated in the processor. Using a special display, the operator can select one of the possible modes. A correct execution This mode will be provided automatically.

In terms of the functions performed, automation for gas heating boilers can be of two main types:

• room thermostat;
• weather-sensitive.

Room thermostat

In the first case, the main indicator for controlling the operation of a gas boiler is the room temperature. Depending on this temperature, the boiler operating mode is selected. When the temperature in the room drops, the boiler starts working, and when the temperature exceeds a preset level, it will turn off.

Thermostat designs may vary. For example, SEITRO's thermostat operates using a membrane sensor. At a certain temperature, the sensor closes and a switching command is sent to the gas boiler.

Thermostats can be installed in any convenient location premises, and communication with the gas boiler control unit can be carried out using a cable or wireless connection.

SEITRO thermostat

A type of thermostat is a programmer. From such a programmer, commands are transmitted to the gas boiler throughout the day, in accordance with which its operating mode is carried out. The work cycle is repeated every day.

Weather-compensated automatic gas boiler operates based on temperature environment on the street. Appropriate adjustment of the automation allows you to maintain a constant climate in the house when the outside air temperature changes.

Weather-compensated automation

Basic automation functions

The main functions of the automatic gas heating boiler are the following functions:

• automatic start of the gas boiler;
• stopping the operation of the gas boiler;
• control and adjustment of burner power using an appropriate sensor;
• emergency stop of the gas boiler in case of any malfunction.

When you turn on the gas boiler, the automation first starts the hardware of the system. In this case, the temperature is measured and the amount of gas that must be supplied to the gas burner is estimated. On next stage the automation starts the gas fittings, as a result of which gas is supplied to the system. At the same time, a spark is ignited in the combustion chamber, which ignites the gas. Under the influence of the flame in the heat exchanger, water is heated, which is then supplied to the batteries.

One of the options is automatic sabc for a gas heating boiler

An important part of the automation system of a gas heating boiler is the safety subsystem. This includes:

• overheating protection;
• frost protection;
• anti-blocking;
• anticyclical function;
• control of flame and draft presence.

To protect against overheating, duplication of sensors is often used - temperature sensor and limit thermostat. To protect against freezing, when the water is cooled to a temperature of + 5 degrees, the automation lights the burner and heats the water.

Anti-locking provides automatic switching on pump every 24 hours to combat scale. The anti-cycling function assumes that the automation prevents frequent ignition of the burner, which reduces its working life. When a signal of lack of flame or draft appears, the automation system turns off the gas supply.

In volatile automation systems, the gas supply is turned off using an electromagnetic valve through which gas enters the burner. The valve automatically turns off if the gas supply stops. The disadvantage of such a valve is that when gas appears, it cannot open automatically and must be done manually. At the same time, if there is a power failure, after restoration electrical circuit, the system starts automatically.

Modern automation systems for gas heating boilers allow reliable and safe operation of gas boilers

In modern automation systems for gas boilers, system malfunctions are diagnosed automatically. The results of this diagnostic are shown on the display. This greatly facilitates and speeds up the repair of a gas boiler.

Bottom line

Choosing which automation to buy for a gas boiler it is necessary to understand that the most modern systems are energy dependent. If the customer has doubts about the reliability of the electrical network in his home, then it is necessary to consider the use of non-volatile automation systems.

Video review and honeywell automation for a gas boiler:

The presented video shows an overview of the 630 Eurosit automation for gas heating boilers

The American company Honeywell was founded by Albert Buts immediately after his invention of the simplest control device for operating a coal furnace. Today, enterprise automation can be found in both domestic and foreign boilers.

The uniqueness of Honeywell products is the ability to select high-precision monitoring equipment for almost any purpose.

Automation for a Honeywell gas boiler may have a simple device equipped with a mechanical regulator. It can also be manufactured as a highly sensitive unit with the ability to automatically adjust the operating mode, depending on the heating of the rooms and the ambient temperature.

What is Honeywell automation

If you describe in simple language, then the automation system for gas boilers from Honeywell is an operation control unit heating equipment. Depending on the modification, the main functions and tasks may change, but in general the main control is exercised over the following systems:

If we take into account the five main processes controlled by automation for Honeywell gas boilers, the role and purpose of this unit for the operation of water heating equipment becomes clear.

The main goal of the company is to ensure reliability and safety through the operation of the boiler controller. Both the budget series and the premium modification use only high-quality components that undergo mandatory testing in the factory.

How Honeywell systems work

As already noted, automation is a regular thermostat that turns on and off when certain conditions are reached. The more complex the automation unit is, the more more possibilities control it provides.

Modern versions of control valves are controlled by a microprocessor and have a built-in programmer for the boiler, which allows you to set the temperature regime several days in advance.

A conventional gas valve has simple design. Temperature is set using mechanical regulators, and the operating principle is based on the use of a thermocouple. Despite this device, mechanical regulator gas supply is no different in reliability from expensive analogs with digital control, but is inferior to them in the number of available functions.

Why do we need control systems from Honeywell?

Although the Russian consumer is primarily familiar with Honeywell because of what is included in the boiler package domestic production, in fact, the control unit can be found in European products, including well-known brands, for example.

Boilers equipped with modern gas automatics Honeywell operate in completely autonomous mode, independently changing settings depending on the weather outside. Control is carried out using a remote panel or remote control remote control. Adjustment of Honeywell automation in this case is also carried out automatically, using a special program.

Why is automation necessary? It serves two main purposes:

The automation is set up in the factory; on site, the technician may be required to connect remote room sensors to the controller and install all additional equipment.

Honeywell automation is a fairly good option for use as control valves. In addition to high quality and reliability, the control unit has another undoubted advantage. Honeywell components are easy to obtain and are almost always in stock, so even the most complex repairs will not take much time.

Below we will describe the most incomprehensible malfunction in the entire history of our work. Moreover, we are not 100% sure until the end. We understood almost completely the details of what was happening and have already resolved this issue more than once with the most positive result. But, nevertheless, some uncertainty is still present. Maybe this will go away over time, after completely disassembling the valve, when possible. OK then...

Main symptoms. It starts as if from afar. There are no signs of trouble. For no apparent reason, the working boiler suddenly turns off. The boiler may be working properly for several months before this starts. Or maybe even several years. Well, it turned off, and it turned off. We approach the boiler. Let's launch. Works. After this strange failure, a day or even a week usually passes. And the situation repeats itself. The boiler may turn off, for example, at night. After this, boiler shutdowns become more frequent, and as a result, the boiler cannot be started at all. We release the button and the igniter goes out.

Something that usually immediately confuses specialists .(but the problem is the same!!!)

1. Everything is fine. Idling works. (The igniter is lit.) You exhibit desired temperature. The boiler reaches this temperature and suddenly turns off along with the igniter. Then, the boiler cannot be started at all until it cools down. After a couple of hours, the boiler can be turned on, but the situation immediately repeats itself. Or something else...

2. Launch boiler. It works. It's gaining temperature. Cotton. Gas release from igniter. Everything goes out. And then, until the boiler has cooled down completely, you don’t even have to come close. The gas worker, for example, cleaned the pilot burner. Dayit worked and again the same story.

Next, look at the top picture. What do you usually do right away? They pull off the wires from No. 3, wind a wire jumper and try to start the boiler. After the boiler does not start, and it usually does not start in 90% of cases, almost everyone begins to blame the gas valve, claiming that it is faulty, or the solenoid valve located inside the gas valve. Replacing the gas valve with new problem does not eliminate. Or, as mentioned above, a day passes, or, at best, a week. And then a complete repeat of the situation. This, of course, got old very quickly, but let’s not blame anyone who could help us, right? Therefore, let's get down to business.

Entering information 04/17/2013 To quickly diagnose such a malfunction, see the article. Here is a specific list of actions that will help “revive” the boiler or repair it.

1. First we will get used to the big picture. Let's approach the boiler and use our eyes to find everything we need here by looking at the elements. There is no way without this.

2. Then we will analyze the work of each element in this chain separately. This will greatly help to see the overall picture of the boiler's operation.

3. Let's make a diagnosis and figure out the situation together. I advise you to take your time and study everything carefully, because the matter here is so delicate that if you don’t have basic attentiveness, you won’t be able to do anything. Run to change the boiler for a new one, as some people usually advise, having been stuck with the boiler until late at night, or just quietly let the oak go to minus -30C, buying up all the thermocouples, valves, and giving away about ten of them for nothing.

We are working.

1.This is a Honeywell gas valve. There may be another valve. By the way, I must say that this malfunction directly affects AOGV boilers with a capacity of 11.6, 17.4 and 23.2. These boilers are equipped with simple valves. There are more complex valves, for example or Honeywell, that use two thermocouples: one - , the other, multiple - . These blocks cost AOGV 29.1 or more powerful boilers. We are not talking about them now.

2. This is a thermocouple. It is heated by an igniter and generates EMF. This EMF keeps the valve open. The thermocouple will cool down and the valve will close. Thermocouples for Honeywell blocks - . If you need to know more about the work - .

3. This is a thermocouple breaker. It is also called a "thermal breaker". The great setback is that breakers are only supplied for Eurosit units. They have M9 thread. And the Honeywell unit has a thread for an M10 breaker.

4. Thermal relay 90C. Or 95C. 90C is the temperature at which the relay is activated. Boiler boiler protection.

5. Button KM1-1. Or a small-sized button KM1-1. Doesn't matter. Essentially a regular electrical push-button switch.

6. Thermal plate. Here it is a little different. Not the same as installed on your boiler. Your thermal plate has a nut welded in and an adjusting screw. If there is poor draft in the chimney, the plate bends and presses the KM1-1 button. The boiler turns off.

When we looked, found all the elements and even felt them with our hands, we move on to analyzing the work of each element separately.

1. Gas valve "Honeywell".

Currently not supplied by the factory. More precisely, it is still being staged as it was, only under a different name - Mertik Maxitroll. This is not an analogue, this is what it is. Remove the cover from yours and you will see this name. To start the boiler, we turn the handle to the “Spark” position and push it down. The gas went to the igniter. After that, we turn the handle, click the piezoelectric element (in this block it is built into the valve and controlled by the handle), the igniter lights up and wait 30-45 seconds for the thermocouple to warm up. After this, release the handle. The solenoid valve remains in the open position, powered by EMF from the thermocouple. Turn the second knob of the temperature regulator, opening the gas to the main burner. The burner is lit by a working igniter.

2. Thermocouple. The thermocouple is placed at one end into the igniter flame and, when warmed up for 30-45 seconds, begins to generate an EMF of 20 mV. This 20 mV keeps the block solenoid valve in the open position..

Automated control systems increase production efficiency, the intensity of product output and its quality, and allow the operation of complex equipment without failures or malfunctions in strict accordance with occupational safety requirements. The most advanced ideas require the use of modern, high-tech materials, elements, and devices.
