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

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

Automation for gas boiler Honeywell may have a simple device equipped with a mechanical regulator. It can also be made as a highly sensitive unit with the possibility of automatic adjustment of the operating mode, depending on the heating of the rooms and the ambient temperature.

What is Honeywell automation

In simple terms, Honeywell's automation for gas boilers is a control unit for the operation of heating equipment. Depending on the modification, the main functions and tasks may vary, but in general, the main control is exercised over the following systems:

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

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

How Honeywell systems work

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

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

Ordinary gas valve It has simple design. The temperature regime is set using mechanical regulators, and the principle of operation 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 inferior to them in terms of the number of available functions.

What are Honeywell control systems for?

Although Honeywell is primarily familiar to the Russian consumer by 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 Honeywell gas automation operate in full offline, independently changing the settings depending on the weather outside. Management 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 needed? It serves two main purposes:

Adjustment of automation is carried out at the factory, on site the master may be required to connect remote room sensors to the controller and install all additional equipment.

Honeywell automation is enough a good option for use as control valves. Apart from High Quality and reliability, the control unit has another undeniable advantage. Honeywell parts are easy to get and almost always in stock, so even the most complex repairs will not take much time.

Automated control systems increase production efficiency, product output intensity and quality, allow complex equipment to be operated without failures, malfunctions in strict accordance with labor safety requirements. The most advanced ideas require the use of modern, high-tech materials, elements, and devices. One of the world's leading manufacturers electronic systems management, automation, control is the American corporation Honeywell.

The most incomprehensible malfunction in the history of our work will be described below. And, to the end, we are not 100% sure. We sorted out the details of what was happening almost completely and more than once resolved this issue with the most positive result. But, nevertheless, some kind of uncertainty is still present. Maybe this will pass with time, after the complete disassembly of the valve, when there is an opportunity. OK then...

Main symptoms. It starts as if from afar. Nothing portends trouble. For no apparent reason, a working boiler suddenly turns off unexpectedly. The boiler can work properly for several months before this starts. Or maybe even a few years. Well, turned off, and turned off. We approach the boiler. We 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 that, the boiler shutdowns become more frequent, and as a result, the boiler cannot be started at all. We release the button, the igniter goes out.

What usually immediately confuses specialists .(but the same fault!!!)

1. Everything is fine. Idling works. (The igniter burns). You set the desired temperature. The boiler picks up this temperature and suddenly cuts out 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 else...

2. Launch boiler. Works. Picks up temperature. Cotton. Emission of gas from the igniter. Everything goes out. And then, until the boiler cools down completely, you can not even approach. The gasman, for example, cleaned the pilot burner. Dayworked and again the same story.

Next, look at the top picture. How do they usually act? 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 without exception everyone begins to sin on the gas valve, claiming that it is faulty, or the solenoid valve located inside the gas valve. Gas valve replacement new problem does not eliminate. Or, as mentioned above, a day passes, or, at best, a week. And then a complete repetition of the situation. This, of course, got tired very quickly, but let's not blame anyone from those who could help us, right? Therefore, let's get down to business.

Entering information 17.04.2013 For a quick diagnosis of 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 go to the boiler, and with our eyes we will find by the elements everything that we need here. Nothing 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.

3. Let's make a diagnosis and figure out the situation together. I advise you not to rush and carefully study everything, because here the matter is so delicate that if there is no elementary attentiveness, you will not be able to do anything. Run to change the boiler for a new one, as some people usually advise, having bothered with the boiler until late at night, or just quietly give the oak to minus -30C, buying all the thermocouples, valves, and giving away about ten 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 concerns 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, using two thermocouples: one -, the other, multiple -. These blocks are on AOGV 29.1 and more powerful boilers. We are not talking about them now.

2. It's a thermocouple. The igniter heats it, it generates EMF. This EMF keeps the valve open. The thermocouple will cool down - the valve will close. Thermocouples for Honeywell units - . If you need to know more about the work -.

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

4. Thermostat 90C. Or 95C. 90C is the temperature at which the relay is triggered. Boiler protection.

5. Button KM1-1. Or a small button KM1-1. Doesn't matter. Essentially an ordinary electric push button switch.

6. Thermoplate. Here it is a little different. Not the same as installed on your boiler. Your thermoplate has a nut welded in and an adjusting screw. At bad traction in the chimney, the plate bends and presses the KM1-1 button. The boiler is switched off.

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

1. Honeywell gas valve.

Currently not installed by the factory. More precisely, how it was put and put, only under a different name - Mertik Maxitroll. It's not analog, it's what it is. Remove the cover from yours and you will see this name. To start the boiler, we turn the knob to the "Spark" position, push it down. The gas went to the igniter. After that, we turn the knob, click the piezoelectric element (in this block it is built into the valve and controlled by the knob), the igniter lights up and wait 30-45 seconds until the thermocouple warms up. After that, release the handle. The solenoid valve remains in the open position, powered by the EMF from the thermocouple. We turn the second knob of the temperature regulator, opening the gas to the main burner. The burner lights up from a working igniter.

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

Domestic 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 in the heat generator regulate combustion and help to maintain required temperature.

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

Automatic system protects heating installations from overloads and activates an emergency shutdown of the gas supply in case of sudden force majeure. Additionally, the technique regulates the level of combustion intensity and current consumption fuel, allowing owners to save financial resources for space heating.

The automatic node 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:

  • devices with energy dependence;
  • energy independent devices.

Systems of the first type are complex electronic units and for correct operation, which need uninterrupted supply electricians. The second types of devices are simplified mechanical structures that do not require energy supply.

View #1 - volatile products

Volatile module- This is a small electronic device that responds to the supply of a fuel resource. Turns on and off at the moment of activation or closing of the main gas cock. Is different complex design and large quantity elements and microcircuits.

Allows hosts to perform the following tasks:

  • activation or termination of gas supply;
  • starting the heating system in automatic mode;
  • adjustment of the power level of the base burner (due to the presence of a thermostat);
  • turning off the operating boiler both in emergency situations and within the user-defined mode;
  • output of current indicators to the display ( general level air temperature in the room, the mark to which the working coolant is warmed up, etc.).

More "fancy" modules have additional functionality and offer users unlimited and most convenient conditions for monitoring the operation and controlling the unit. Electronic panels provide full protection of the heating equipment from malfunction and prevent the boiler from freezing.

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

The option of self-diagnosis, available for individual modules, prevents malfunctions and contributes to the timely detection 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 difficulties and entail cash spending associated with 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 safe operation equipment, provides smooth operation boiler, prevents the system from overheating and cuts off the gas supply in the event of a drop in draft or attenuation of the flame in the burner.

The assortment line of volatile automation, presented on the market today, pleases with diversity. Useful and necessary mini-aggregates are produced by world-famous brands and small companies that are just trying to win their place in the sun.

Energy-dependent automation is presented in the form of a control panel, where the user can set the parameters of the equipment that are convenient for him. 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 on offer there are both simple products, and more advanced units with a programming option.

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

View # 2 - non-volatile units

Non-volatile automation more simple and practical. Management 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 works completely autonomously and does not need to be connected to the central electrical system.

For residential heating and supply hot water in taps, it is enough to turn the control knob in the direction of increasing by 2-3 divisions. If you want to take a bath or shower, the toggle switch must be set to the maximum value.

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 is actively working until the room warms up to the desired temperature. Then the temperature controller turns off the gas supply to the system and is activated again only when the room becomes colder.

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

The physical characteristics of this progressive material endow it with the ability to capture minimal temperature fluctuations almost instantly.

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

The presence of a non-volatile automatic control system allows users to set the most suitable temperature regime for themselves in a house or apartment and save fuel resources without overpaying 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 immediately stops 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 unforeseen surges in the central power grid

The correct operation of the flame sensor is ensured by a special plate. During normal and correct functioning of the system, it is in a slightly bent state.

In this way, the part keeps the shut-off valve in the " Open". When the flame becomes smaller, the plate is leveled and the valve closes under its pressure.

Design and principle of operation

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 comfortable mode for the user.

Components of the 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 the gas in a timely and reliable manner and prevents leakage.
  2. Thermostat– maintains the set temperature of the coolant and protects the system from overheating. When the coolant cools down to the minimum temperatures, the module starts the boiler into operation, and after fixing the peak-high rates, 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 features that increase the comfort of using the equipment.

The device is auto-igniting gas burner, selects the most efficient operating mode, contributes to the rational use of energy resources and conducts independent diagnostics, saving the owners from all these activities.

The principle of operation of safety automation

The current regulatory documentation says that the gas boiler safety complex must be equipped with a device that stops the operation of the entire system and shuts off the gas supply in the event of an unexpected breakdown or any other force majeure.

To accomplish this task, automation must control such parameters as:

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

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

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

With an increase in the number of atmospheres, 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.

Troubleshooting and somehow interfering with the basic functionality of the equipment is prohibited by law. Any problems that have arisen can only be corrected by a qualified specialist - an employee of the gas supply company

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

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

The nuances of the functioning of the system

Volatile electronic automation in work relies on information received from sensors. The microprocessor and the internal controller analyze this data, process and give the system commands that are best suited for a particular situation.

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

Mechanics has a slightly different principle. When the boiler is 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. The ignition stimulates the heating of the thermocouple and voltage is generated on it.

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

Overview of popular models and manufacturers

In the progressive market gas equipment and related elements, automation of both domestic and foreign manufacturers. By the principle of operation, all devices are exactly the same, however, in terms of design, there are significant differences between them.

The presence of control automation in the system gas heating makes it possible to comfortably heat the room and rationally consume 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 much more valuable, but provide the user with more advanced options for individual settings and control of work.

Some devices, such as SABC automation, in addition to basic functions, are equipped with a built-in pressure stabilizer. This allows for more fine adjustment operation of gas equipment
