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 required temperature.
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 financial resources for space heating.
The automatic unit has flexible settings and allows the owner to set the most convenient operating parameters for the equipment.
By basic principle work 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 and for correct operation, they require uninterrupted supply electricians. 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. Different complex design And a large number 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;
- display of current indicators ( general level air temperature in the room, the point to which the working coolant is 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.
Small breakdowns of the heating system eventually turn into global complications and entail spending money related to the repair and dismantling (full or partial) of equipment. Self-diagnosis helps to identify a malfunction and makes it possible to eliminate it in a timely manner.
Electronic automation, responsible for the safe operation of equipment, ensures 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 that are just trying to earn 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 simple products, as well as 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.
Availability of 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. During normal and correct operation of the 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:
- Flame controller– consists of two main parts – a solenoid valve and a thermocouple. Shuts off gas promptly and reliably and prevents leakage.
- 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.
- 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.
- 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 regulatory documentation 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 supply of the resource immediately stops. This happens automatically due to the presence of a valve mechanism set to a certain value.
Energy dependent 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 maintain the valve in the 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.
The presence of control automation in a gas heating system 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 over a wide 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 operation.

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 for gas boilers from Honeywell is a control unit for the operation of 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 control possibilities 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. The temperature regime is set using mechanical regulators, and the operating principle is based on the use of a thermocouple. Despite such a device, a mechanical gas supply regulator is no different in reliability from expensive analogues 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 famous brands, for example, . Boilers equipped with modern gas automatics Honeywell, fully operational offline mode, independently changing the 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 enough 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 set the 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.It's gas Honeywell 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. Thermocouple 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 the 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 welded nut and an adjusting screw. At bad traction 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, as it was put and put, 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.

The German company Honeywell has a history of more than a century (founded in 1885 by the inventor of the thermostat and regulator for a coal furnace, Albert Butts) and during this time has become one of the world leaders in the production of various types of automation, including automation for gas boilers.
Honeywell products have always been different high accuracy, efficiency and quality, regardless of the price niche, be it budget mechanical thermostats or high-tech weather-sensitive automatic modules, and is therefore in high demand all over the world.
This company has representative offices in 95 countries, including almost all countries of the former Soviet Union.
Prices
As already noted, the Honeywell brand of automatic equipment for a gas boiler in its assortment has offers for various wallet options. There are the simplest, fairly cheap automation mechanisms, the price of which ranges from $40-60, such as, for example, Honeywell vs8620, Honeywell v5475, Honeywell v9500. These automatic systems have a basic set of controllers that contribute to the safety of the gas boiler and maintenance certain temperature energy carrier (water) in the system, technical characteristics with the most popular indicators, equipped with a mechanical handle for switching temperature modes. These systems are capable of:
- automatically maintain the specified coolant temperature (from 40 to 90 oC)
- automatically turn off the boiler when gas disappears;
- automatically turn off the boiler if there is no draft in the chimney or if reverse draft occurs;
- automatically turn off the gas supply when the fire goes out.
Operation of Honeywell vs8620 automation
But, you understand, if there is a thaw outside, then a boiler equipped with such the simplest system automation will still work the way you configured it in severe frost, which will lead to excessive heating of the room and unreasonable consumption of energy resources. Also, it will maintain the same heating mode, for example, during the day, when the whole family is at work and there is no need for good heating premises, which is also an unreasonable expense gas fuel. In this case, you will have to constantly adjust and reconfigure the automation parameters manually whenever external factors change.
In most rooms there is a so-called passive time of day for heating, when people leave it and it is enough to maintain a temperature that does not allow the heating system to freeze. As a rule, in residential premises it is day, and in office premises it is night. It is calculated that lowering the temperature of the heated room at this time by only 1 °C leads to savings of 6%. And if you constantly regulate the operation of the boiler, bringing it to optimal performance– you can save 40-50% of your budget on gas fuel.
For those who do not want or do not have the opportunity to constantly adjust the boiler settings themselves, but at the same time want to save energy resources and constantly be in a comfortable indoor climate, there is modern Honeywell electronic automation for a gas boiler, which can be programmed to maintain a certain temperature in the room depending on on weather conditions (weather-dependent automation), as well as changes in the temperature in the room, depending on the time of day and even days of the week. Moreover, this automation can operate in both heating and cooling modes. For example, one of the most multifunctional such models are considered to be the Smile series models, capable of monitoring and managing several heated/cooled circuits at once, for example, heating, hot water, ventilation, “warm floors”, pool heating, etc.
Honeywell automation has always stood out from many competitors due to its high quality, expressed in accuracy and efficiency. Moreover, this is inherent in all models, regardless of the price niche, be it budget mechanical thermostats or high-tech weather-dependent automatic modules
But this system belongs to the premium class of the company’s products and, accordingly, has a very low-budget price, which can fluctuate depending on the specified parameters and required technical characteristics.
In the line of Honeywell automation systems for gas boilers, there are also middle-class models, which, for example, have only several heating modes, depending on the time of day and days of the week, but do not control the street temperature. Such models include, for example, chronothermostats of the Honeywel ST series or programmable thermostat Honeywell YRLV430A1005.
In the video below you can see and hear about the characteristics of the Honeywell YRLV430A1005 programmable thermostat, but, unfortunately, only in English.
It is also worth noting that all Honeywell automation has very accessible, intuitive control modules. Whether it’s the simplest mechanical temperature switch knobs or control modules for multifunctional systems, any average person can handle them by reading the available instructions.
To summarize, we note that Honeywell automation for a gas boiler is available in very wide range, allowing you to select controllers with optimal technical characteristics, suitable for your equipment, needs and wallet.
