When considering home heating options, the most common choice is to use gas boiler. If there is a main gas pipeline near the house, this heating option is considered the most economical and efficient.
When installing any heating boiler, including gas, automation is a mandatory component of the system. Such automation for heating boilers allows, without human intervention, to maintain the specified climatic conditions in the heated room and ensure optimal conditions operation of such a boiler.
What does automation for gas heating boilers consist of?
Typically, such automation includes the following elements:
- fittings These are actuators that, under the influence of commands, turn the boiler on and off, and also regulate its power;
- valves designed to shut off the gas supply;
- maximum and minimum pressure switch. Designed to protect the system when pressure drops or increases too much;
- thermostat;
- water and gas pressure sensors;
- controller - an electronic device that, based on the data received, calculates the optimal operating mode of a gas boiler and generates control commands.
Types of automation for heating boilers
From a power supply point of view, there are two types of automatics for gas boilers:
- non-volatile automation;
- volatile automation.
These two types of automation differ in that the first system does not require power from electrical network, and for the second one to work, electricity must be supplied
Accordingly, these two automation systems will include different elements.
Non-volatile automation is simpler and more reliable, as it does not react to a sudden power outage.
Non-volatile automation
Such automation systems include:
- ignition system, which uses a piezoelectric element;
- thermostat;
- draft and flame sensor.
Mechanical automation begins to work after starting the boiler. Depending on the temperature of the heated water, the thermostat changes the amount of fuel supplied to the burner. Structurally, the thermostat is a metal rod. It changes its length with temperature changes. Thus, it opens or closes the gas supply.
The draft and flame sensor is designed to interrupt the gas supply when the burner flame goes out or there is poor draft in the chimney. Structurally, such a sensor consists of a bimetallic plate, which, under the influence of temperature, changes its position and closes the gas supply.
The control and measuring equipment used in such systems is a pressure gauge and a thermometer. This system is configured manually.
Modern non-volatile automation systems for gas boilers can have a much larger number of components. For example, Italian non-volatile automation has the following components:
- temperature switching and control system;
- flame protection system;
- device for setting minimum gas flow;
- pressure regulator;
- thermostat with burner shut-off function.
Volatile automation
Volatile automation is more complex. Such an electronic system includes a larger number of elements.
For regulation in volatile automation, electromagnetic valves are used. The operation of these valves is carried out according to commands generated in the processor. Using a special display, the operator can select one of the possible modes. A correct execution This mode will be provided automatically.
In terms of the functions performed, automation for gas heating boilers can be of two main types:
- room thermostat;
- weather-sensitive.
Room thermostat
In the first case, the main indicator for controlling the operation of a gas boiler is the room temperature. Depending on this temperature, the boiler operating mode is selected. When the temperature in the room drops, the boiler starts working, and when the temperature exceeds a preset level, it will turn off.
Thermostat designs may vary. For example, SEITRO's thermostat operates using a membrane sensor. At a certain temperature, the sensor closes and a switching command is sent to the gas boiler.
Thermostats can be installed in any convenient location premises, and communication with the gas boiler control unit can be carried out using a cable or wireless connection.
SEITRO thermostat
A type of thermostat is a programmer. From such a programmer, commands are transmitted to the gas boiler throughout the day, in accordance with which its operating mode is carried out. The work cycle is repeated every day.
The weather-sensitive automatic gas boiler operates taking into account the outside ambient temperature. Appropriate adjustment of the automation allows you to maintain a constant climate in the house when the outside air temperature changes.
Weather-compensated automation
Basic automation functions
The main functions of the automatic gas heating boiler are the following functions:
- automatic start of the gas boiler;
- stopping the operation of the gas boiler;
- control and adjustment of burner power using an appropriate sensor;
- emergency stop of the gas boiler in case of any malfunction.
When you turn on the gas boiler, the automation first starts the hardware of the system. In this case, the temperature is measured and the amount of gas that must be supplied to the gas burner is estimated. On next stage the automation starts the gas fittings, as a result of which gas is supplied to the system. At the same time, a spark is ignited in the combustion chamber, which ignites the gas. Under the influence of the flame in the heat exchanger, water is heated, which is then supplied to the batteries.
One of the options is automatic sabc for a gas heating boiler
An important part of the automation system of a gas heating boiler is the safety subsystem. This includes:
- overheating protection;
- frost protection;
- anti-blocking;
- anticyclical function;
- control of flame and draft presence.
To protect against overheating, duplication of sensors is often used - a temperature sensor and a limit thermostat. To protect against freezing, when the water is cooled to a temperature of + 5 degrees, the automation lights the burner and heats the water.
Anti-blocking ensures that the pump automatically turns on every 24 hours to combat scale. The anti-cycling function assumes that the automation prevents frequent ignition of the burner, which reduces its working life. When a signal of lack of flame or draft appears, the automation system turns off the gas supply.
In volatile automation systems, the gas supply is turned off using solenoid valve, through which gas enters the burner. The valve automatically turns off if the gas supply stops. The disadvantage of such a valve is that when gas appears, it cannot open automatically and must be done manually. At the same time, in the event of a power failure, after the electrical circuit is restored, the system starts automatically.
Modern automation systems for gas heating boilers allow reliable and safe operation of gas boilers
In modern automation systems for gas boilers, system malfunctions are diagnosed automatically. The results of this diagnostic are shown on the display. This greatly facilitates and speeds up the repair of a gas boiler.
Bottom line
Choosing which automation to buy for a gas boiler it is necessary to understand that the most modern systems are energy dependent. If the customer has doubts about the reliability of the electrical network in his home, then it is necessary to consider the use of non-volatile automation systems.

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.
The room thermostat is connected 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.
Modern devices can not only control temperature, but also conduct self-diagnosis technology. 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 easy manual control. After self-installation owner required temperature, heating is maintained in automatic mode, 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. The main element of a thermocouple is 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 - 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 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.

American company Honeywell was founded by Albert Butts immediately after his invention of a simple control device for operating a coal furnace. Today, enterprise automation can be found in both domestic and foreign boilers.
The uniqueness of Honeywell products is the ability to select high-precision monitoring 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 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.
What is Honeywell automation
If you describe in simple language, then the automation system for gas boilers from Honeywell is a control unit for the operation of heating equipment. Depending on the modification, the main functions and tasks may change, but in general the main control is exercised over the following systems:
If we take into account the five main processes controlled by automation for Honeywell gas boilers, the role and purpose of this unit for the operation of water heating equipment becomes clear.
The main goal of the company is to ensure reliability and safety through the operation of the boiler controller. Both the budget series and the premium modification use only high-quality components that undergo mandatory testing in the factory.
How Honeywell systems work
As already noted, the automation is a regular thermostat that turns on and off when it reaches certain conditions. The more complex the automation unit is, the more control possibilities it provides. Modern versions of control valves are controlled by a microprocessor and have a built-in programmer for the boiler, which allows you to set the temperature regime several days in advance.
Ordinary gas valve It has simple design. Temperature is set using mechanical regulators, and the operating principle is based on the use of a thermocouple. Despite such a device, a mechanical gas supply regulator is no different in reliability from expensive digitally controlled analogues, but is inferior to them in the number of available functions.
Why do we need control systems from Honeywell?
Although the Russian consumer is primarily familiar with Honeywell because of 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 gas automatics Honeywell operate in completely autonomous mode, independently changing settings depending on the weather outside. Control 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 necessary? It serves two main purposes: 
The automation is set up in the factory; on site, the technician 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. Besides High Quality and reliability, the control unit has another undoubted advantage. Honeywell components are easy to obtain and are almost always in stock, so even the most complex repairs will not take much time.
