Honeywell automation for a gas boiler – quality proven over a century. Honeywell automation for a gas boiler: what it is and the advantages of the system Honeywell automation for gas boilers
The German company Honeywell has a history of more than a century (founded in 1885 by the inventor of the thermostat and regulator for coal furnace Albert Buts) and during this time became one of the world leaders in production various kinds automation, including automation for gas boilers.
Honeywell products have always been distinguished by high accuracy, efficiency and quality, regardless of the price niche, be it budget mechanical thermostats or high-tech weather-sensitive automatic modules, therefore it is 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, Honeywell brand automation for gas boiler In its assortment it has offers for various wallet options. There are the simplest, fairly cheap automation mechanisms, the price of which ranges from $40-60, such as Honeywell vs8620, Honeywell v5475, Honeywell v9500. These automatic systems have basic set controllers that contribute to the safety of the gas boiler and maintaining a certain temperature of the energy carrier (water) in the system, technical characteristics with the most popular indicators, are 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 bitter 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 the budget for gas fuel payments.
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 a modern electronic automation Honeywell for a gas boiler, which can be programmed to maintain a certain temperature in the room depending on weather conditions (weather-dependent automation), as well as to change temperature regime indoors, 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 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 gas boilers is available in a very wide range, allowing you to select controllers with optimal technical characteristics, suitable for your equipment, needs and wallet.
Below we will describe the most incomprehensible malfunction in the entire history of our work. Moreover, we are not 100% sure until the end. The details of what was happening were understood almost completely and this issue had been resolved more than once with a positive result. But, nevertheless, some uncertainty is still present. Maybe it will go away with time, after complete disassembly 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. Idle speed 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 solenoid valve, located inside the gas. Replacing the gas valve with a new one does not solve the problem. 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 units are installed on AOGV 29.1 and 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 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..

Automation for heating units can be divided into:
- volatile (operating from the power supply network);
- non-volatile (mechanical devices).
Types of volatile systems
An autonomous gas boiler involves the installation of complex electronic devices, dependent on the power supply network. These devices independently adjust the fuel supply and flame power.
Room thermostats
Volatile automation systems are presented the following types devices:
- daily programmer;
- programmer for a week.
Room thermostat Mounted in a room where the temperature needs to be controlled. Sensors take measurements.
When the temperature drops, the thermostat reacts and sends a signal to the gas boiler. The boiler starts.
Upon reaching optimal temperature indoors, the valve closes and the gas boiler stops working.
Connects room thermostat to the unit using 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. After 24 hours the cycle resumes.
The device is connected to the gas unit using a cable and via a radio channel.
Programmer for a week. Such a weekly device has more possibilities for changing the indoor climate. There are built-in modes and those that can be configured manually. The action takes place within a radius of 30 meters or more. Data can be monitored on the backlit display.
Devices can be selected by color depending on the design of the room.
Devices modern type can not only control the temperature, but also conduct independent diagnostics of equipment. They control the performance of the pump and protect the gas boiler from freezing.

Operating principle of non-volatile automation
Energy-independent devices are autonomous, they do not care about the presence of an electrical network, they have an easy manual control. After self-installation 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 compliance of the temperature with the set parameters is monitored. installed in the heat exchanger, records the temperature of the coolant. Main element thermocouples are an 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 coolant changes. One sensor is sensitive to deterioration in smoke draft, the other is sensitive to a strong decrease in gas pressure in the pipe. The principle of operation of the automation is the same: expansion or deformation of the material under strong heating. The draft sensor, which is located in the smoke hood, includes a bimetal plate. As traction deteriorates, flammable smoke gases accumulate and overheat the plate. The plate bends, the contacts are disconnected, and gas does not enter the combustion chamber. The flame sensor functions in a similar way.
Despite the convenience of electronics, many still choose mechanical automation for a gas boiler. There are several reasons for this:
- Control of such automation is elementary.
- A non-volatile system costs much less than devices that consume energy.
- It is not afraid of power outages or power surges, which does not force you to purchase.
Manufacturers
Many companies that produce automation for gas units also produce solid units, which contain all the most necessary devices:
- thermostat;
- valve;
- pressure meter;
- performance relay.
The automation design may vary depending on the manufacturing company, although the devices function by analogy. Automation from Italy SIT is reliable and simple. The most popular model is the 630 EUROSIT.
Domestic analogues can be seen under the SABC and Orion brands.
