Automation for gas boilers: types, principle of operation
5 (100%) votes: 1Modern automation ensures the reliability and high operating 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 the heating equipment, since 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 shut down on its own 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 for heating units can be divided into:
An autonomous gas boiler implies 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 represented by the following types of devices:
Room thermostat mounts in a room where you want to regulate the temperature. The sensors are taking measurements.
When the temperature drops, the thermostat reacts and sends a signal to the gas boiler. The boiler starts up.
Upon reaching optimal temperature indoors, the valve closes and the gas boiler stops working.
The room thermostat is connected to the unit with a cable.
Daily programmer. Functions of this appliance the same as for the thermostat, but it is possible to set programs for a day. The programmer also works with a hot water supply system. After 24 hours, the cycle resumes.
The device is connected to the gas unit using a cable and radio channel.
Weekly programmer. Such a weekly appliance has more possibilities for changing the indoor climate. There are built-in modes and those that can be manually configured. The action takes place within a radius of 30 meters or more. The data can be monitored on the backlit 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 pump operation and protect the gas boiler from freezing.

Energy-independent devices are autonomous, they do not care about the availability electrical network, they have easy manual control. After self installation by the owner of the required temperature, heating is maintained in automatic mode, that is, by adjusting the gas supply to.
The automation for the gas unit operates in this way: in the operating boiler, using a thermostat, which is connected to the valve and supplies fuel to the burner, the temperature is monitored for the set parameters. installed in the heat exchanger records the temperature of the heat carrier. The main element of the thermocouple is the Invar rod. He is sensitive to temperature changes. The rod acts on the gas regulating valve, 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 the draft and flame sensors is similar to the operation of the boiler automation when the temperature of the heat carrier changes. One sensor is sensitive to a deterioration in smoke draft, the other to a strong decrease gas pressure in the pipe. The principle of operation of the 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 draft 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 functions in a similar way.
Despite the convenience of electronics, many still choose mechanical automation for gas boiler... There are several reasons for this:
Many companies that produce automation for gas units also manufacture solid blocks, which have all the most necessary devices in stock:
The automation device may vary depending on the issuing company, although the devices function by analogy. Automation from Italy SIT is reliable and simple. The 630 EUROSIT model is in the greatest demand.
Domestic counterparts can be seen under the brands SABK and Orion.
American Honeywell gas boiler automation is one of the most popular.
Honeywell has been known since 1885 and is currently one of the leaders in the production of various automation.
The popular Honeywell VR 400 model has two servo valves for operation with electronic boiler control units or remote controllers. The device has the following characteristics:
Honeywell products are high-precision, high-quality and efficient regardless of the price category, which is why they are so popular in many countries. Budget automation for a gas boiler from this company costs about $ 50 (models Honeywell vs8620, Honeywell v5475, Honeywell v9500). Such devices include:
Honeywell systems can perform the following functions:
Automation for a Honeywell gas boiler is currently popular and is produced in a large assortment, so the buyer always has a choice of controllers. The safety automation of gas boilers from Honeywell has established itself as a high-quality, accurate and efficient technology. And this applies to all models of the company, regardless of the price.
Modern automation for gas heating boilers is of great importance in safe operation heating device, and now it is almost impossible to do without it. Foreign models of automation are distinguished by high reliability and long service life, which is proved by the time-tested operation of devices on different gas boilers.
The American company Honeywell was founded by Albert Butts immediately after his invention of the simplest regulator device for operating a coal furnace. Today, the automatics of the enterprise 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 can 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.
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 class modification, only high-quality assemblies are used that undergo mandatory testing in the factory.
As already noted, the automation is a conventional thermostat that turns on and off when it reaches certain conditions... The more complex the automation unit is, the more control it provides. Modern versions of control valves are controlled by a microprocessor, they have a built-in programmer for the boiler, which allows you to set the temperature regime for several days in advance.
Normal gas valve It has simple design. Temperature regime 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 analogs with digital control, but it is inferior to them in terms of the number of available functions.
Although the Russian consumer is primarily familiar with the Honeywell company by what is included in the boiler package domestic production, in fact, the control unit can be found in European products, including well-known brands, for example,. The boilers, equipped with modern Honeywell gas automatics, operate in a completely autonomous mode, independently changing the settings depending on the weather outside. Control is carried out using a remote control panel or a remote control. In this case, the adjustment of the Honeywell automation is also carried out automatically, using a special program.
What is automation needed for? It serves two main purposes: 
Automation adjustment is carried out at the factory, on site from the master it may be required to connect external room sensors to the controller and install all additional equipment.
Honeywell Automation is enough a good option for use as a control valve. In addition to high quality and reliability, the control unit has another undoubted advantage. Honeywell parts are easy to obtain and nearly always in stock, so even the most complex repairs won't take long.
Automated control systems increase the efficiency of production, the intensity of production and its quality, and allows to operate complex equipment without failures, malfunctions in strict accordance with labor safety requirements. The most advanced ideas require the use of modern, high-tech materials, elements, devices.
