Maintaining a pleasant temperature in your home is not easy: traditional heating systems are static and do not take into account weather changes throughout the day and season. At the same time, to residents, a difference of several degrees seems significant and can completely destroy the desired comfort. However, in last years Electronics have made it possible to make a huge step in this area, because with its help it is possible to create heating systems that respond to temperature changes almost with the sensitivity of a living organism.
In heating systems with weather regulation Having received a signal from temperature sensors that it has become warmer or colder outside, programmable controllers, based on a graph depending on the outside air temperature, calculate how much the batteries need to be heated (or cooled) and send a control signal to the valve in the heating circuit. Following the instructions of the controller, it slightly opens or, conversely, partially closes the damper, allowing boiling water from the boiler or heating network to be added to the coolant in strictly required proportions.
In modern heating systems, the programmable controller responsible for such delicate work is given vital role. The Moscow company has been developing such devices for over 20 years and has accumulated extensive experience in this area.
Controllers and, developed and manufactured by OWEN, regularly serve in utility systems, regulating the temperature in heating and hot water supply (DHW) circuits. However time is running, and equipment requirements are increasing. Today the company has prepared for release a new controller (Fig. 1) with expanded capabilities, designed to regulate temperature in both one and two independent circuits. In other words, these devices can be used:
In one heating circuit or underfloor heating;
In one DHW circuit;
In two heating circuits;
In two hot water supply circuits;
In one heating system and one domestic hot water system.
It will be in demand in housing and communal services engineering systems, block individual heating points (IHP), systems with dispatching.
Versatility (one controller can be used for automation various types systems);
Flexibility (easily reconfigured to work with one or two circuits);
Easy to set up.
Controller capabilities
The controller performs all the necessary functions that are in demand today in building engineering systems, including “ smart home" It provides:
Automatic tuning of PID controllers;
Automatic selection of modes (heating/night/summer, etc.);
Diagnostics emergency situations(break of communication lines, pump malfunction);
Setting the values of process parameters using the built-in keyboard or on a PC via the RS‑485 and RS‑232 network;
Support for OWEN, Modbus-RTU, Modbus-ASCII exchange protocols;
Possibility of firmware update ( necessary devices included in the delivery package);
Quick setup of the controller from the panel or using the configurator.
Using the proportional-integral-derivative control law, it controls and regulates the temperature of the coolant in the circuits and the temperature return water. In addition, it measures the temperature of outside air, direct water, and pressure in the make-up circuits. The controller generates control signals for the output elements and ensures that the temperature in the circuit is maintained in accordance with a fixed setpoint (for DHW circuits) or a schedule (for heating system circuits). It has a built-in real-time clock to manage the heating schedule. Specifications are presented in table. 1.
The controller is equipped with a symbolic liquid crystal indicator, thanks to which it is convenient to configure and operate the device using a push-button keyboard. The indicator displays measured values, operating modes and messages about emergency situations in the system.
For single-circuit systems
The controller allows complete automation of one circuit without additional modules.
Automatic temperature control in the circuit in accordance with the outside air (direct water) temperature schedule or with a given setpoint;
Automatic temperature control trev in accordance with the return water temperature schedule with protection against over/under temperature;
Charge pump control;
Rice. 1. Smile controller
Changes in operating parameters allow you to achieve a certain level of flexibility in the control of heating systems. Although these controllers have strict operating algorithms, they can be adapted to a specific scheme. Let's say the controller controls a mixing circuit consisting of a valve, a pump and two sensors on the supply and return pipelines. When changing certain parameters responsible for the mixing valve, you can connect the hot water supply system circulation pump to the controller, place temperature sensors in the heat exchanger - and the controller no longer controls the heating system circuit, but completely controls the operation DHW systems. That is, the same output can be used for various components scheme. This flexibility is relevant when reconstructing premises with additional heating circuits, for example, partial replacement radiator heating on a “warm floor” or expansion of the hot water system. In this case, one controller will control the “warm floor” system, radiator heating, boiler and hot water supply system.
It is possible to connect remote modules with indoor air temperature sensors. The connected modules have a knob for changing settings and a mode switch “Economical/Scheduled/Comfortable”, a digital display, and duplicate the controller setting buttons, providing full access mode and remote control. Individual control of a separate heating circuit from one room is possible. To do this, it is necessary to integrate a wall module of a suitable model into the heating system.
Technical characteristics of Smile controllers: electricity consumption - 5.8 VA, operate from a household AC network. Protection degree IP 30. Dimensions (WxHxD) - 144x96x75 mm. The housing is made of ABS plastic with antistatic coating. Maximum length buses - 100 m. The device is mounted on the wall using terminal boxes.
Modern controllers are suitable both for creating weather-dependent systems for regulating the temperature of the coolant flow (for example, radiators, convectors), and for systems where it is necessary to maintain a constant temperature of the coolant (for example, underfloor heating systems, or for swimming pools) through mixing circuits, including solar systems.
By using several “stand alone” controllers, you can create a fairly large and complex system controls, suitable even for large public buildings.
In individual construction, controllers make it possible to organize systems in which it is possible to use various heat generators, including those using alternative sources energy.
It is almost impossible to create such systems without controllers. After all, all their components have different algorithms and operating modes. It is advisable to turn on an electric boiler at night, when the electricity tariff is cheaper (with multi-tariff metering). Or use a heat pump at the same time. During daylight hours, the solar system collectors are turned on, and during peak loads on the hot water supply in the morning and evening, you cannot do without gas boiler. Accordingly, it is possible to turn off the electric boiler during the daytime. In this case, all heat sources work on the accumulator, the temperature in which also needs to be controlled and, in accordance with it, the operation of the entire system must be balanced. At the same time, a work schedule is established by time of day and days of the week.
Combined schemes
One of the current ones is the use of gas and electric boilers or a gas boiler and a solid fuel boiler in one system (the first as the main one, the second as an additional one) (Fig. 2).
Rice. 2. Scheme with the combined use of electric and gas boilers:
AF, WF1, WF2, VF1, RLF1, SF - temperature sensors (outside air, boilers, coolant in the supply and return pipelines, hot water storage tank); MK1 - three-way mixing valve with electric drive; Tmax - overhead thermostat; P1, SLP, ZKP - pumps
In the first case, since it is advisable to turn on the electric boiler at night, when the electricity tariff is lower, a timer with a daily, weekly schedule and a weekend program is used. In the second case, in the absence of gas, a solid fuel boiler will ensure that the heating and hot water systems operate at the required level. Also heat sources various types fuels make it possible to ensure reliable operation of the system under other certain force majeure circumstances.
In this case, the controller provides control of the boilers, limitation of the maximum temperature at the outlet of the boilers, stepless (smooth) control of the gas boiler with optimal load on it. It is possible to organize work management taking into account the air temperature in the room and weather correction. Anti-freeze, automatic legionella protection and hot water priority functions are available.
Connection heat pump allows you to create systems in which alternative energy is the base for heating water in buffer capacity(Fig. 3).
Rice. 3. Using a gas boiler, heat pump and buffer tank:
AF, WF, VF1, KSPF, VE1, SF - temperature sensors for outside air, boiler, coolant on the supply pipeline, at the inlet and outlet of water from the buffer tank, and the hot water storage tank; KVLF - water temperature sensor; MK1, VA1- three way valves with electric drive; P1 - pump of the mixing circuit of the heating system; VA2- buffer tank loading pump from the heat pump
At the same time, automation will provide control of the water temperature at the outlet of the heat pump and optimization of equipment operation processes. In this scheme, the base heat source is the heat pump, and the gas boiler covers the peak load of the system. Greater freedom in choosing fuel can be provided by a scheme using a solid fuel boiler and solar collector (Fig. 4).
Rice. 4. Scheme using a solid fuel boiler, solar collector and buffer tank:
AF, WF1, VF1, VE1, SF, VE2, KSPF, KRLF, KVLF - temperature sensors for outside air, boiler, coolant on the supply pipeline, at the water outlet from the buffer tank, the DHW storage tank, water at the inlet to the DHW storage tank from the solar collector, at the water inlet to the buffer tank, at the water inlet to solar collector, water in the solar collector; MK1, MK2, U1 - three-way mixing valves with an electric drive (heating system circuit, to maintain the set temperature at the inlet to the solid fuel boiler, valve between the buffer tank and the solar collector); P1 - heating mixing circuit pump
This ensures the maintenance of a given temperature at the inlet and outlet of the boiler, control of the water temperature in the solar collector, and switching of the flow of water entering the solar collector from the hot water tank and buffer tank. Parallel weather-compensated operation with a mixing heating circuit is possible.
To create large heating systems, it is often necessary to connect boilers in a cascade, which controllers can also handle (Fig. 5). This ensures optimal parameters and accounting of the operating hours of each heat generator.
Rice. 5. Connecting gas boilers in a cascade:
AF, WF1, WF2, VF1, VF2, VF3, SF, RLF1, RLF2 - temperature sensors for outside air, boiler, coolant in the supply pipeline, hot water storage tank, water in the return pipeline; MK1, MK2, MK3, R1, R2 - three-way mixing valves with electric drive
In any case, for specific conditions, you can choose the most appropriate scheme, of which manufacturers of control devices offer dozens.
Perspective - universal controller
Currently, there is a noticeable trend towards more complex building air conditioning systems. Controller developers are adapting to this trend accordingly.
These devices already allow you to send data about the operation of systems via mobile communications or via the Internet. For example, in the USA, touchscreen monitors with the ability to integrate with operating systems Android smartphones. Thus, it is possible to remotely control operating parameters climate systems, which may include not only heating, but also ventilation systems, air conditioning, security and fire systems.
Because the different manufacturers protected their products with various data transfer protocols, controllers have now appeared that allow the use of all existing protocols (for example, CentraLine (Honeywell)). This is especially true in the case of installing regulators at modernized facilities.
However, with the increasing complexity of systems, the question arises of creating a kind of universal controller. This is currently the main perspective and challenge for developers. A single controller, depending on what is included in it software can be used to control various engineering systems building. This is a kind of small computer for which you only need to install “software” for specific tasks and program it directly for a specific object.
The difficulty of implementing freely programmable controllers lies, first of all, in the high cost of the software. In addition, the issue of compliance with the level of user training, the availability of qualified maintenance personnel and the exclusion of unauthorized interference in the operation of control devices is relevant.

Constantly monitoring the operation of the heating system requires a lot of effort and time. However, the emergence of new control devices can significantly simplify this process, and in some cases completely automate it. To do this, you will need to install an appropriate controller for heating and boiler control systems.
Purpose of heating controllers
The main purpose of this electronic device is to change the parameters of control devices connected to it to correct their operation. The most simple example an elementary similar control element can be considered a control automatic protection system in gas boilers. But controllers for heating and hot water supply have wide functionality.
They are an electronic unit with the ability to control the main elements of the heating system. To do this, it provides the ability to program parameters depending on the data received, from external temperature and pressure sensors. Thus, a controller for a heating boiler can regulate the operation of a heated floor collector or individual thermostats on radiators.
TO general characteristics electronic control units include the following:
- System flexibility. To connect to heating components, you do not need to reprogram the device. In most cases, manufacturers provide several operating modes for one connection terminal;
- Possibility of choice convenient place to install the control panel. Controller heating Honeywell can be mounted at a distance of up to 100 m from the control element;
- Monitoring the functioning of not only heating systems, but also hot water supply;
- If you have a GPS unit, you can receive data online about the state of the heating and send commands to change its parameters.
The function of connecting the device to a computer is also important. A similar additional module is installed on the Aries heating controller. It is noteworthy that it is not included in the required package.
The controller can be installed on an old gas boiler. To do this, just change the heating pad to a new modular one.
Selecting a heating controller
In what cases is it necessary to install a heating control controller? First of all, this device is necessary when residents are often absent from the house or apartment. By connecting the electronic unit to external temperature sensors (outdoor and indoor) and boiler control terminals, you can use the built-in software package set up an automatic change in the burner operating intensity.
How to choose the optimal controllers for heating systems? The easiest option is to consult with specialists. But nowadays it is difficult to find one, since this product is relatively new. Therefore, it is recommended that you first study the basic selection parameters yourself:
- When comparing a controller for a heating boiler, make sure that installed equipment has the ability to connect to the control unit. Most often, the boiler is characterized by one-stage or two-stage external control. This only applies to gas models– coordination with solid fuel is impossible;
- Number of managed components. For a Honeywell heating controller, this value can reach 15 depending on the specific model;
- Availability of GPS unit. As mentioned above, this function makes it possible to remotely control the heating;
- Software update frequency. The modern controller of heating and hot water systems TRM 32 can be connected directly to a computer. You can always find it on the manufacturer's website latest version BY.
An additional function is to adjust the operation of the components according to the configured heating schedule. This feature is provided in the Aries heating controller. You should also pay attention to the accuracy of measurements. IN professional models this indicator should not exceed ±0.01 scale.
Repair of heating controllers is rare. But it is still recommended to choose a manufacturer who has service centers in the region of residence.
Review of popular controller models
Having decided on the required parameters of controllers for heating and hot water supply, you can begin to analyze the products offered. Despite a large assortment, the market is oversaturated with low-quality models. Their actual parameters do not correspond to the declared ones, which subsequently leads to incorrect operation of the heating. Let's look at truly popular and reliable examples of heating control controllers.
Honeywell
Among the entire product range of the company, the Smile SDC7-21N model occupies a special place. In addition to an affordable price, it is characterized by optimal functionality, which is important for heating system controllers.
It is important for the consumer to know the characteristics of an electronic device. It should immediately be noted that for optimal performance Honeywell controller in the heating system will need to purchase additional modules - terminal blocks for connecting system components, a set of temperature sensors, a 3-way mixing valve and actuators. After assembling the controller, it will be possible to control heating and hot water according to the following parameters:
- The ability to regulate the operation of the boiler burner with two-stage control;
- Simultaneous control of 2 cascade type boilers. But for this you will need to install an additional temperature sensor at the output of the second one;
- Controller for heating system can adjust the direct and mixing circuit depending on the street and room temperature;
- DHW pump control;
- Possibility of setting a 7-day heating control program.
In its minimum configuration it will only work as a controller for a heating boiler. But this will not prevent you from purchasing additional modules and upgrading the system over time. The cost of a complete set is about 45 thousand rubles.
Best to buy full set equipment, since all its components are guaranteed to work normally when connected to each other.
Aries TRM 32
If you need to choose an option for more affordable price– it is recommended to pay attention to the heating controller Aries TRM 32. This domestic product is in no way inferior in functionality to its foreign analogues. It is noteworthy that with its help you can control not only heating, but also hot water supply according to several parameters.
You should immediately warn that the controller unit for heating and hot water systems TRM 32 is more massive than the similar Honeywell one. Therefore, you need to think about the location of its installation in advance. In addition to it, the manufacturer offers a remote panel.
As for functionality, in addition to standard capabilities, the following features of the controller for heating and hot water supply of this type should be noted:
- Automatic maintenance of water temperature in the DHW circuit;
- Using PID controllers, high accuracy of coolant temperature is ensured;
- Built-in heating protection against reverse water flow;
- Day/night mode available. This function is especially relevant for two-tariff electricity meters
But the most interesting for the consumer is the cost of the Aries heating controller. Basic model price without additional equipment is 8-10 thousand rubles.
Is it possible to install a controller for heating and boiler control systems yourself? Despite the apparent complexity, the instructions for each model describe in detail which terminals the heating components should be connected to. If you carefully study technical documentation controller and boiler - you can install the automation yourself.
