Rice. 1. Smile controller
Changes to operating parameters allow you to achieve a certain level of flexibility in the management of heating systems. Although these controllers have rigid algorithms of work, 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, it can be connected to the controller circulation pump hot water supply systems, place temperature sensors in the heat exchanger - and the controller no longer controls the heating system circuit, but completely controls the operation of the DHW system. That is, the same output can be used for different circuit components. This flexibility is relevant when reconstructing premises with additional heating circuits, for example, partial replacement of radiator heating with a "warm floor" or expanding the DHW system. In this case, one controller will also 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 plug-in modules have a knob for changing the settings and a switch of the “Economy / Schedule / Comfort” modes, a digital display, and duplicate the controller settings buttons, providing a mode of full access and remote control. Individual control of a separate heating circuit from one room is possible. To do this, a wall module of a suitable model must be built into the heating system.
Technical characteristics of Smile controllers: power consumption - 5.8 VA, they operate from a household AC network. Protection degree IP 30. Dimensions (W × H × D) - 144 × 96 × 75 mm. The housing is made of anti-static ABS plastic. Maximum length busbars - 100 m. The device is wall-mounted using terminal boxes.
Modern controllers are suitable both for creating weather-dependent systems for regulating the temperature of the heat carrier flow (for example, radiator, convector), and for systems where it is necessary to maintain a constant temperature of the heat carrier (for example, systems of the "warm floor" type, or for swimming pools) by means of mixing circuits, including heliosystems.
Using several "stand alone" controllers, it is possible to create a sufficiently large and complex control system, suitable even for a large public building.
In individual construction, controllers allow you to organize systems in which it is possible to use various heat generators, including those using alternative energy sources.
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 the electric boiler at night, when the electricity tariff is cheaper (with multi-tariff metering). Or use a heat pump at the same time. During the daytime, the solar collectors are switched on, and at peak loads on hot water supply in the morning and in the 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 operate on a storage tank, the temperature in which must also be controlled and, in accordance with it, the operation of the entire system must be balanced. At the same time, a work schedule is laid down by time of day and days of the week.
One of the most relevant is the use of gas and electric boilers in one system or a gas boiler and a solid fuel boiler (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 (outdoor air, boilers, heating agent in the supply and return pipelines, hot water storage tank); MK1 - electrically operated three-way mixing valve; Tmax - surface-mounted thermostat; P1, SLP, ZKP - pumps
In this case, 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 day, weekly schedule and a weekend program is used. In the second case, in the absence of gas, the solid fuel boiler will maintain the operation of the heating and hot water supply systems at the required level. Also heat sources on different types fuels allow to ensure the reliability of the system under certain other force majeure circumstances.
In this case, the controller provides control of boilers, limitation of the maximum temperature at the outlet from the boilers, stepless (smooth) control of a gas boiler with optimal load on him. It is possible to organize the control of work taking into account the air temperature in the room and weather correction. Anti-freeze, automatic anti-legionella 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 a buffer tank (Fig. 3).
Rice. 3. Using a gas boiler, heat pump and buffer tank:
AF, WF, VF1, KSPF, VE1, SF - sensors for the temperature of the outside air, boiler, coolant in the supply pipeline, at the inlet and outlet of water from the buffer tank, DHW 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- pump for loading the buffer tank from the heat pump
At the same time, the automation will provide control of the water temperature at the outlet of the heat pump and optimization of the equipment operation processes. In this scheme, the base heat source is the heat pump and the gas boiler covers the peak loads of the system. Greater freedom of choice of fuel can be provided by a scheme using a solid fuel boiler and a 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 - sensors for the temperature of the outside air, boiler, coolant in the supply pipeline, at the outlet of water from the buffer tank, 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, a valve between the buffer tank and the solar collector); P1 - pump of the mixing circuit of the heating system
This ensures that the set temperature at the inlet and outlet from the boiler is maintained, the temperature of the water in the solar collector is monitored, and the flow of water entering the solar collector from the DHW tank and the buffer tank is switched. 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 is also handled by controllers (Fig. 5). At the same time, optimal parameters and accounting of the operating hours of each heat generator are ensured.
Rice. 5. Connecting gas boilers to a cascade:
AF, WF1, WF2, VF1, VF2, VF3, SF, RLF1, RLF2 - temperature sensors for the outside air, boiler, coolant in the supply pipeline, DHW 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 dozens of control device manufacturers offer.
Currently, there is a tendency towards more sophisticated air conditioning systems in buildings. Developers of controllers adapt accordingly to this trend.
These devices already allow you to send data about the operation of systems via mobile communication or via the Internet. For example, in the USA wide use received touchscreen monitors with the ability to integrate with the operating systems of smartphones such as Android. Thus, it is possible to remotely control the operating parameters of climate systems, which can include not only heating, but also ventilation systems, air conditioning, security and fire systems.
Since different manufacturers have protected their products with different data transfer protocols, now there are controllers that allow using all existing protocols (for example, CentraLine (Honeywell)). This is especially true when regulators are installed 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 embedded in it software can be used to control various engineering systems of a building. This is a kind of small computer, for which it is only necessary to install "software" for specific tasks and program it directly for a specific object.
The complexity of the implementation of freely programmable controllers lies, first of all, in the high cost of the software. In addition, the issue of compliance with the level of training of the user, the availability of qualified service personnel and the exclusion of unauthorized interference in the operation of control devices is relevant.

Therefore, we recommend that, if installation is necessary, contact our qualified specialists who have passed special training courses and have extensive experience in setting up and commissioning this equipment.
Controller control screen on the example of ST-409n
The owner can adjust the brightness of the controller screen to different day and night. When you press the "Night" icon, a panel is displayed for adjusting the appearance of the screen at night: Same as Day, Clock or Off. This screen is activated at night after 20 seconds from the last touch on the screen. To return to the main menu, simply touch the screen. The user can define the time at which the controller switches to night mode (Night from hour) and at which it returns to day mode (Day from hour).
The controllers provide the ability to remotely control heating via the Internet using an additional Internet module Tech ST-505 or Tech WiFi RS.
The Internet module is a device that allows you to remotely control the operation of the boiler via the Internet and a local Wi-Fi network. The user controls the state of all boiler devices on the computer screen, the operation of each device is presented in the form of animation. In addition to the ability to view the temperature of each sensor, the owner has the ability to change the set temperatures of the pumps and mixing valves. After enabling the Internet module and selecting the DHCP option, the controller will automatically configure the parameters of the local network, such as: IP address, subnet mask, gateway address, DNS address. If you have problems loading the network parameters, you can set them manually.
If there is no Wi-Fi network at the dacha, you can remotely control the heating using the Tech controller and the Tech ST-65 module GSM.
The GSM module is additional device which works with the boiler controller. The owner is informed about all alarms by means of SMS messages, and by sending a corresponding SMS message, he receives a response with information about the current temperature of all sensors. It is also possible to change temperatures remotely after entering the appropriate code. The GSM module can also operate independently of the boiler controller. It consists of two inputs with temperature sensors, one docking input for use in any configuration (NO and NC contact) and one control output (for example, with the ability to connect an additional contactor to control any electrical circuit). Make or break contacts can be used, for example, for simple protection of property.

In such cases, with the controller to protect the heating system from various emergency positions, it is used safety unit... And also apply additionally flow control sensors(coolant), special valves.
In the house you can use thermostatic valves or room temperature controllers... The first one permits to ask desired mode to any source, and the second is responsible for the operation of the pump, which supplies the coolant to the radiator.
If there is no Internet in a private house, then it is used GSM module allowing you to control the situation via your smartphone.
Pay attention to the nuances when installing the controller:
You can do it yourself with a controller connect in two options:
Important! Such a process not worth doing in the kitchen or bathroom, since due to a possible increase in temperatures, malfunctions in the thermostat are permissible.
Practically each boiler has special contacts for connection controller to it. It is required to find this place and remove the jumpers and connect the thermostat. About, how to set up the device itself and start it working, indicated in the instructions.
have successfully passed many years of testing in engineering systems Housing and communal services. On their basis, a new controller for heating and hot water supply systems has been developed - ... Unlike its predecessors allows you to control one- and two-circuit heating and hot water supply systems.
Maintaining a pleasant temperature in your home is not easy: traditional heating systems are static and do not take into account the weather changes during the day and the season. At the same time, a drop of several degrees seems significant to residents and is able to completely destroy the desired comfort. However, in recent years, electronics has made it possible to take a huge step in this area, because with its help it is possible to create heating systems that react to temperature changes almost with the sensitivity of a living organism.
In heating systems with weather regulation, having received a signal from the temperature sensors that it is warmer or colder outside, the programmable controllers, according to the schedule depending on the outside air temperature, calculate how much to heat (or cool) the batteries, and send a control signal to the valve in the heating circuit ... Following the instructions of the controller, he slightly opens or, conversely, partially closes the damper, allowing boiling water from the boiler or heating network to be added to the coolant in the strictly required proportion.
The programmable controller responsible for such delicate work in modern heating systems the most important role is assigned. The Moscow company has been developing such devices for over 20 years and has accumulated extensive experience in this area.
The controllers and, developed and released by the OWEN company, regularly serve in the engineering systems of housing and communal services, regulating the temperature in the heating and hot water supply (DHW) circuits. However, as time goes on, the requirements for equipment are increasing. Today the company has prepared for release a new controller (Fig. 1) with expanded capabilities, designed to control 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 circuits of hot water supply;
In one heating system and one DHW system.
It will be in demand in engineering systems of housing and communal services, block individual heating points (ITP), systems with dispatching.
Versatility (one controller can be used for automation different types systems);
Flexibility (easily reconfigured to work with one or two circuits);
Easy to set up.
