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 a 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. Replacing the gas valve with a new one does not fix the problem. 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 been 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 holds open valve. 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. With poor draft 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. gas valve Honeywell.

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 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 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.

Honeywell automation is an affordable multifunctional non-volatile device that allows you to regulate the gas supply, taking into account the water temperature and electrical energy in the system.

Honeywell gas valve is able to create a mode effective use fuel and a high rate of fire safety.

Choosing and purchasing Honeywell spare parts is no longer a problem, just look here. You can also consult with experts.

Modern automation ensures reliability and high working efficiency of gas boilers. Automation allows you not to worry about the safety of the boiler, and makes its use comfortable and economical. The owner does not need to constantly pay attention to heating equipment, as the system is automated. Thanks to the ability to fine-tune the devices, the owner can easily set and change the operating parameters.

An automatic gas boiler can even turn itself off in the event of an emergency. Automation devices clearly set the parameters of combustion and fuel consumption. This gives the owner the opportunity to save money on space heating.

Automation SIT 630 EUROSIT

Automation for heating units can be divided into:

volatile (functioning from the power supply network);
non-volatile (mechanical devices).

Types of volatile systems

An autonomous gas boiler involves the installation of complex electronic devices that are dependent on the power supply network. These devices independently adjust the fuel supply, flame power.

Room thermostats

Volatile automation systems are represented by the following types of devices:

programmer for a day;
weekly programmer.

Room thermostat mounted in a room where you want to regulate the temperature. Sensors take measurements.

When the temperature drops, the thermostat reacts and sends a signal to the gas boiler. The boiler starts up.

Upon reaching optimum temperature indoors, the valve closes and the gas boiler stops working.

connects room thermostat to the unit with a cable.

Daily programmer. The functions of this device are the same as those of the thermostat, but it is possible to set programs for the day. The programmer also works with the hot water supply system. The cycle restarts after 24 hours.

The device is connected to the gas unit using a cable and via a radio channel.

weekly programmer. Such a weekly device has more opportunities for changing the indoor climate. There are built-in modes and those that can be configured manually. The action takes place in a radius of 30 meters or more. Data can be monitored on the illuminated display.

Devices can be selected by color depending on the design of the room.

Devices of a modern type can not only control the temperature, but also carry out independent diagnostics of equipment. They control the operation of the pump and protect the gas boiler from freezing.

The principle of operation of non-volatile automation

Energy-independent devices are autonomous, they do not care about the presence of an electrical network, they have easy manual control. After self installation the owner of the required temperature, heating is maintained automatically, that is, by adjusting the gas supply to.

Automation for a gas unit functions in this way: in a working boiler, using a thermostat, which is connected to a valve and supplies fuel to the burner, the temperature is monitored to match the set parameters. , installed in the heat exchanger, fixes the temperature of the coolant. The main element of the thermocouple is the invar rod. It is sensitive to temperature changes. The rod acts on the valve that adjusts the gas supply, it lengthens when heated and becomes shorter when cooled.

As the temperature rises, the flow of fuel becomes less - and the flame goes out until the rod becomes cold.

The principle of operation of draft and flame sensors is similar to the operation of boiler automation when the temperature of the heat carrier changes. One sensor is sensitive to a deterioration in smoke draft, the other is sensitive to a strong decrease in gas pressure in the pipe. The principle of operation of automation is the same: expansion or deformation of the material with strong heating. The draft sensor, which is located in the smoke hood, includes a bimetal plate. As thrust deteriorates, combustible smoke gases accumulate and overheat the plate. The plate bends, the contacts are disconnected, the gas does not enter the combustion chamber. The flame sensor works in a similar way.

Despite the convenience of electronics, many still choose mechanical automation for gas boiler. There are several reasons for this:

The control of such automation is elementary.
A non-volatile system costs much less than devices that consume energy.
Not afraid of a power outage, power surges, which does not force you to purchase.

Manufacturers

Many companies that produce automation for gas units also produce solid blocks in which all the most necessary devices are available:

thermostat;
valve;
pressure meter;
execution relay.

The automation device may vary depending on the issuing company, although the devices operate by analogy. Automation from Italy SIT is reliable and simple. The 630 EUROSIT model is in the greatest demand.

Domestic analogues can be seen under the brands SABC and Orion.

The German company Honeywell has more than a century of history (founded in 1885 by the inventor of the thermostat and regulator for a coal stove, Albert Bats) 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 precision, efficiency and quality, regardless of the price niche, be it budget mechanical thermostats or high-tech weather-compensated automatic modules, therefore it is in high demand all over the world.
Representative offices of this company are available in 95 countries of the world, including almost all countries of the former Soviet Union.

Prices

As already noted, the Honeywell brand automation for a gas boiler in its range has offers for various wallet options. There are simple, 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 maintain a certain temperature of the energy carrier (water) in the system, technical specifications with the most popular indicators, are equipped with a mechanical temperature control knob. These systems are capable of:

automatically maintain the specified coolant temperature (from 40 to 90 °C)
automatically turn off the boiler when the gas disappears;
automatically turn off the boiler in the absence of draft in the chimney or in the event of reverse draft;
automatically turn off the gas supply when the fire goes out.

Operation of Honeywell vs8620 automation

But, you yourself understand, if there is a thaw outside, then a boiler equipped with such a simple automation system will still work the way you set it up 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 consumption of gas fuel. In this case, you will have to constantly adjust and reconfigure the automation parameters manually with any change in external factors.

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 prevents the heating system from freezing. As a rule, in residential premises it is day, and in office premises it is night. It is calculated that a decrease in the temperature of the heated room at this time by only 1 ° C leads to a saving of 6%. And if you constantly regulate the operation of the boiler, bringing it to optimal performance, you can save 40-50% of the budget for paying for gas fuel.
For those who do not want or do not have the opportunity to constantly adjust the boiler settings on their own, but at the same time want to save energy and be constantly in a comfortable room 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 from weather conditions (weather-dependent automatics), as well as for changing the temperature regime 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 versatile of these models are the models of the Smile series, which are able to control and manage 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 by its high quality, expressed in accuracy and efficiency. Moreover, this is inherent in all models, regardless of the price niche, whether it is budgetary 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 non-budget price, which can vary depending on the specified parameters and the required technical characteristics.
In the line of Honeywell automation systems for a gas boiler, there are also middle-class models that, for example, have only a few heating modes, depending on the time of day and days of the week, but do not control the street temperature. These models include, for example, the Honeywel CT series chronothermostats or the Honeywell YRLV430A1005 programmable thermostat.

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 automations have very accessible, intuitive control modules. Whether it's the simplest mechanical temperature switch knobs or control modules for multifunctional systems, any average layman can handle them by reading the available instructions.

Summing up, we note that honeywell automation for a gas boiler is available in very a wide range, allowing you to choose controllers with optimal technical specifications, suitable for your equipment, needs and wallet.
