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 brand automation of the Honeywell brand for gas boiler in its assortment has offers for various possibilities of the wallet. 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 produced in a very a wide range, allowing you to choose controllers with optimal technical specifications, suitable for your equipment, needs and wallet.

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 gas valve, claim that it is faulty, or the solenoid valve located inside the gas. 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 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. 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 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.


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 a Honeywell gas boiler 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 work control unit 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.

The conventional gas valve has simple design. 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 package of domestic-made boilers, in fact, the control unit can be found in European products, including well-known brands, for example,.

Boilers equipped with modern gas automation Honeywell, operate in a completely autonomous mode, independently changing 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. In addition to high quality and reliability, the control unit has another undoubted 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.
