Controllers for heating TECH Controllers. Aries trm232m - a new controller for heating and hot water systems Controller for heating and hot water
Maintaining a pleasant temperature in the house is not easy: traditional heating systems are static and do not take into account weather changes during the day and season. At the same time, for residents, a difference of several degrees seems significant and is capable of completely destroying the desired comfort. However, in last years electronics made it possible to make a huge step in this area too, 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 weather-controlled heating systems, having received a signal from temperature sensors that it has become warmer or colder outside, programmable controllers, according to the graph depending on the outdoor temperature, calculate how much it is necessary to warm up (or cool down) the batteries, 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 system to be added to the coolant in the strictly required proportion.
A programmable controller responsible for such delicate work, in modern heating systems ah relegated essential role. The Moscow-based company has been developing such devices for over 20 years and has accumulated extensive experience in this area.
Controllers and, developed and released by OWEN, regularly serve in utility systems by regulating the temperature in the heating and hot water supply (DHW) circuits. However, as time goes on, the requirements for equipment increase. Today, the company has prepared for release a new controller (Fig. 1) with enhanced capabilities, designed to control the 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 to automate 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 the engineering systems of houses, including systems " smart home". It provides:
Automatic tuning of PID controllers;
Automatic selection of modes (heating / night / summer, etc.);

Support for ARIES, Modbus-RTU, Modbus-ASCII exchange protocols;
Ability to update the firmware (the necessary devices are included in the delivery);
Quick configuration of the controller from the panel or using the configurator.
Using the proportional-integral-differential 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 the outside air, direct water, pressure in the make-up circuits. The controller generates control signals for the output elements and maintains the temperature in the circuit in accordance with a fixed setpoint (for DHW circuits) or a schedule (for heating circuits). To control the heating schedule, it has a built-in real-time clock. Specifications are presented in table. one.
The controller is equipped with a symbolic liquid-crystal indicator, thanks to which it is convenient to set up and operate the device using the keypad. The indicator displays measured values, operating modes and alarm messages in the system.

Therefore, if installation is necessary, we recommend contacting our qualified specialists who have completed special training courses and have extensive experience in setting up and adjusting this equipment.
Controller control screen using ST-409n as an example
The owner can set different brightness of the controller screen day and night. Clicking the "Night" icon shows a panel for setting the night view of the screen: Daytime, 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, just touch the screen. The user can define the time at which the controller will go into night mode (Night from the hour) and at which it will return to day mode (Day from the 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 pumps and mixing valves. After enabling the Internet module and selecting the DHCP option, the controller will automatically configure the parameters local network such as: IP address, subnet mask, gateway address, DNS address. If you have problems loading network settings, you can set them manually.
In the absence of the cottage WiFi networks can remotely control heating using a Tech controller and a Tech ST-65 GSM module.
The GSM module is an additional device that 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 (make and break contact) and one control output (for example, with the possibility of connecting an additional contactor to control any electrical circuit). Normally open or normally closed contacts can be used, for example, for simple property protection.
Terminals for connecting controllers Tech ST-409n, 408n, 407n
The controllers are equipped with the following protections:

Rice. 1. Smile controller
Changes in operating parameters allow a certain level of flexibility in the management of heating systems. Although these controllers have rigid algorithms of operation, they can be adapted to a specific scheme. Suppose the controller controls a mixing circuit consisting of a valve, a pump and two sensors on the supply and return pipelines. When it changes certain parameters, responsible for the mixing valve, you can connect the circulation pump of the hot water supply system to the controller, place the temperature sensors in the heat exchanger - and the controller no longer controls the heating system circuit, but fully controls the operation of the DHW system. That is, the same output can be used for different circuit components. Such flexibility is relevant in the reconstruction of premises with the equipment of additional heating circuits, for example, partial replacement of radiator heating with a “warm floor” or expansion of the DHW system. At the same time, 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 plug-in modules have a setting change knob and an Economy/Schedule/Comfort mode switch, a digital display, and duplicate the controller's setting buttons, providing full access and remote control mode. Individual control of a separate circuit of the heating system from one room is possible. To do this, it is necessary to integrate a wall module of a suitable model into the heating system.
Specifications of Smile controllers: power consumption - 5.8 VA, they work from household AC mains. Degree of protection IP 30. Dimensions (W×H×D) - 144×96×75 mm. The case is made of ABS plastic with an antistatic coating. Maximum length tires - 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.
Using several "stand alone" controllers, you can create a sufficiently large and complex control system, suitable even for a large public building.
In individual construction, controllers allow organizing systems in which it is possible to use various heat generators, including those using alternative sources energy.
It is practically impossible to create such systems without controllers. After all, all their components have different algorithms and modes of operation. It is advisable to turn on the electric boiler at night, when the electricity tariff is cheaper (with multi-tariff accounting). Or use a heat pump at the same time. During daylight hours, the collectors of the solar system are turned on, and at peak loads on the hot water supply in the morning and evening, one cannot do without gas boiler. Accordingly, it is possible to turn off the electric boiler during the daytime. At the same time, all heat sources work for the 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.
Combined schemes
One of the most relevant is the use in one system of a gas and electric boilers or a gas boiler and a solid fuel boiler (the first one as the main one, the second one as an additional one) (Fig. 2).
Rice. 2. Scheme with the joint use of electric and gas boilers:
AF, WF1, WF2, VF1, RLF1, SF - temperature sensors (outside air, boilers, coolant in the supply and return pipelines, DHW storage tank); MK1 - three-way mixing valve with electric drive; Tmax - overhead thermostat; P1, SLP, ZKP - pumps
Moreover, 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 the reliability of the system under certain other force majeure circumstances.
In this case, the controller provides boiler control, limiting the maximum temperature at the outlet of the boilers, stepless (smooth) control of the gas boiler with the optimal load on it. It is possible to organize work management taking into account the air temperature in the room and weather correction. Frost protection functions are available, automatic protection against legionella, as well as hot water priority.
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. Use of gas boiler, heat pump and buffer tank:
AF, WF, VF1, KSPF, VE1, SF - temperature sensors for outdoor air, boiler, coolant on 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 - heating mixing circuit pump; 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 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 in the 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, a solar collector and a buffer tank:
AF, WF1, VF1, VE1, SF, VE2, KSPF, KRLF, KVLF - temperature sensors for outdoor air, boiler, heat carrier on 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 electric drive (heating 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 maintaining the set temperature at the inlet and outlet of the boiler, controlling the temperature of the water in the solar collector, switching the flow of water entering the solar collector from the DHW tank and the 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 also cope with (Fig. 5). At the same time, optimal parameters and accounting for the operating hours of each heat generator are ensured.
Rice. 5. Connecting gas boilers to the cascade:
AF, WF1, WF2, VF1, VF2, VF3, SF, RLF1, RLF2 - temperature sensors for outdoor air, boiler, coolant in the supply pipeline, DHW storage tank, water in the return pipeline; MK1, MK2, MK3, R1, R2 - electrically operated three-way mixing valves
In any case, for specific conditions, you can choose the most appropriate scheme for them, which manufacturers of control devices offer dozens of.
Perspective - universal controller
Currently, there is a noticeable trend towards the complication of air conditioning systems in buildings. Accordingly, controller developers are also adapting to this trend.
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 wide use received touchscreen monitors with the ability to integrate with operating systems smartphones such as Android. Thus, it is possible to remotely control the operation parameters of climate systems, which may include not only heating, but also ventilation, 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 embedded in it software can be used to control various engineering systems 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 introducing freely programmable controllers lies, first of all, in the high cost of software. In addition, the issue of compliance with the level of user training, the availability of qualified service personnel and the exclusion of unauthorized interference in the operation of control devices is relevant.
