Comfort and energy efficiency in your home both depend on how well you control the temperature. You can accomplish that with a heating control unit that is operating properly. This appliance reduces energy consumption and helps control the heating system in your house, maintaining the desired temperature. Let’s examine the operation of heating control units, their parts, and the reasons they improve the insulation and heating system in your house.
Your heating system’s central nervous system is essentially a heating control unit. In order to know when to turn on or off the heat, it communicates with other sensors and thermostats. This rule makes sure your house stays cool when you’re not using it and warm when you are. A control unit can save energy waste and utility costs by preserving a steady temperature.
The majority of heating control units have a fairly simple design. A central processor, relays or switches to regulate heating components, and interfaces for user settings and thermostat connections are usually what make them up. You can even use voice commands or a smartphone to remotely control your heating system with some of the more advanced models that support smart home integration. With the added convenience of being able to change settings while on the go, this can further improve energy efficiency.
Installing a heating control unit has several benefits. They can, first and foremost, result in significant energy savings by lowering needless heating. This may result in lower monthly utility bills for you. Additionally, they provide increased comfort by preserving a constant interior temperature, which can be crucial in areas with variable weather. Lastly, a seamless experience and increased control over the environment of your home can be had by integrating modern units with other smart home systems.

The design of the traction regulator
A mechanical traction regulator is made up of various parts. The gadget has a handle to install the preferred temperature indicator, regardless of the maker. An alloy that is heat-resistant and temperature-resistant is incorporated into the design. A thermo-sensitive element and a chain that fastens the handle to the lever are features of every traction thermoregulator. The regulator case is made of a robust metal that is unafraid of mechanical deterioration and deformation.
The lever with the chain is connected to the air supply damage. Maintaining fuel combustion in boiler equipment is impossible without enough oxygen. If he does not grab it, the flame will quickly go out. Solid fuel equipment works on different types of fuel, which has different properties, and therefore consumes different amounts of oxygen during combustion. Due to the traction regulator, you can choose optimal conditions for the boiler regarding the type of fuel. The traction regulator will ensure the economical operation of boiler equipment and a comfortable microclimate in the room. Thanks to the use of the device, maximum fuel combustion is excluded, which means that the number of harmful emissions into the environment is reduced.
A heating control unit is the brain behind your home"s heating system, ensuring that it operates efficiently and effectively. It regulates temperature by controlling when the heat turns on and off, usually based on a programmed schedule or sensors that detect room temperature. This device can also help save energy by allowing you to set specific heating times, reducing the need to heat rooms when they"re not in use. The advantages of a heating control unit include greater comfort, energy savings, and the ability to customize heating to suit your lifestyle. Some units even connect to smart home systems, enabling remote control through your smartphone, so you can adjust the temperature on the go. Overall, a heating control unit is a valuable addition to any modern home, providing both comfort and energy efficiency.
Design and principle of operation
Inertia is a feature of fire automation. When creating the control unit, the designer took precautions to ensure that there were no false works and that an overly sensitive sensor wouldn’t cause flooding in the office or production space.
Two sensors must operate in order to turn on the pumps: a thermal sensor in the spraying head and an air or hydraulic sensor in the control node between the outer pipes, which is filled with compressed air or water and has a water reservoir that is blocked by a spring valve. A spraying head is installed on the output.
The UU is separated into the following categories based on the working environment that caused the sensor:
- Air;
- Air control and launch;
- Waterfounded.
Constructively, UU are separated into corners and direct flows. Devices that are explosion-proof are designed for specific situations.
Regulate and initiate UU are equipped to perform remote diagnostics. Regular tests are conducted while they are in operation.
Think about the design and operation of the water-filled UU.
An increase in the moving fluid’s pressure to the compensator activates the control device. When the sprinkler head is opened and the thermal cutter is destroyed, water starts to flow. Unwanted signals can quickly put pressure on the compensator.
For instance, shock waves resulting from the overlap of the large consumer are linked to pressure surges in the water supply network. Such waves have a series of damped effects on the compensator sensor as they travel long distances through the hydraulic system. These hydraulic boards continue for a fraction of a second to ten or thirteen seconds, depending on the initial intensity. For this reason, the sensor UU is made inertial to trigger with a delay.
Liquid will move continuously and have a longer effect on the sensor if the sprinkling head’s shutter was destroyed by heat and water seeped through the holes.
There is an inertial thermal cutter installed in the sprinkler head. A glass flask filled with liquid serves as the terminal’s barely fixed shutter. It is destroyed when the temperature rises because of the stresses brought on by thermal expansion.
Water initially flows out of the holes by gravity and without pressure; however, this is insufficient to put out a fire. However, fluid flow facilitates both the opening of the valve and the water’s passage along the signaling line UU from the outer pipes. Pressure signals are generated, the pump is engaged, and high-pressure water is pumped into the sprayer as a result of the moving fluid’s continuous pressure on the sensor. The flame is effectively put out by a dense cloud of water spray created by a spraying head.
What happens if pressure fluctuations in the tap system cause the compensator’s hydraulic pressure to increase for unrelated reasons? It stops false operations. To do this, delay timers are built into pressure alarms; the timer is set based on predetermined parameters.
An alternate to an electronic timer is a delay camera. Water pressure does not respond to pressure alarms until it is filled. The water in the reserve chamber stops flowing and is drawn into the sewer if the movement of water is due to an unrelated cause other than the sprinkler head opening.
If there are many combustible materials and a high risk of fire, the delay time is minimally displayed. In this instance, the cost of the false operation’s losses is far lower than the fire’s catastrophic costs. When the damage from flooding is similar to the damage from fire, the delay chamber is important.
What are the control units of heating and water supply systems
Any equipment that directs energy or resource toward consumers and modifies its parameters as needed is considered a control node for that type of resource or energy. Even the collector in the home can be linked to the heat control unit, which transfers coolant to different parts of the heating system based on the parameters required.
Elevator nodes, automated control units, and high coolant parameters (overheated to 150 ° with water) can all be installed in the MKD and connected to a heating network. Additionally, the DOS’s parameters can be changed.
One of the primary control functions is performed in the elevator node when the coolant’s parameters (temperature and pressure) are lowered to predetermined levels.
Automation with feedback in an automated control unit controls the coolant parameters, maintaining the required pressure drop in the supply and reverse pipelines and supplying the room with the specified air temperature regardless of the outside air temperature.
There are two varieties of heating system automated control units (AUU CO).
With the first type of auu, the supply and reverse pipelines’ water is mixed with network pumps to bring the coolant temperature to the desired levels without the need to install an elevator. The room’s temperature sensor provides feedback, which the automated process uses to complete the task. Additionally, the coolant pressure is controlled automatically.
The most varied names are given by manufacturers to these kinds of automated nodes: automated mixing unit, heat control unit, weather regulation unit, automated mixing unit, etc. P.
Subtile
Adjustment should be complete
Certain businesses manufacture automated nodes that solely control the coolant’s temperature. An accident may result from a pressure regulator not being present.
The second type of auu forms an independent heating system with plate heat exchangers. Producers frequently refer to them as thermal points. This is untrue and causes uncertainty when making orders.
Liquid thermoregulators (TRSH), which control the water’s temperature and act as automated hydraulic system control units to guarantee that the water is supplied at the specified temperature in accordance with an independent scheme, can be installed in the DHW MKD systems.
As you can see, control nodes are not limited to automated nodes. Furthermore, it is incorrect to believe that TRZH and outdated elevator nodes are incompatible with this idea.
The formation of an erroneous opinion was influenced by the wording in h. 2 tbsp. 166 LCD RF: “Models of control and regulation of thermal energy consumption, hot and cold water, gas”. It cannot be called the correct. Firstly, regulation is one of the management functions, and you should not use this word in the above context. Secondly, the word "consumption" can also be considered excessive: all energy entering the knot is consumed and measured by devices. At the same time, there is no information about the purpose to which the control unit directs thermal energy. We can say more definitely: the control unit of thermal energy consumed for heating (or for DHW).
In the end, we are able to regulate thermal energy to regulate DIA or heating systems. As a result, we’ll refer to them as "hydraulic control system control unit" and "heating system control unit."
The control nodes of the new generation are automated nodes. They enable you to advance the technological level of these systems to the point where the processes of controlling the parameters of the temperature regime of the air in the premises and the water in the hot water supply, as well as the automation of the heat consumption accounting, are fully automated. They also satisfy the most recent requirements for the control subject of heating and hydropower plants.
Due to their design, elevator nodes and TRZh are unable to satisfy the aforementioned specifications. We therefore identify them as belonging to the control nodes of the earlier (older) generation.
Let us now review the initial findings. The control units for DIS and heating systems come in four different varieties. Determine the type of control unit you are selecting.
The principle of the functioning of the traction regulator
The regulation of the air supply to the combustion chamber forms the foundation of the traction regulator’s operation principle. For the intensive combustion of fuels, oxygen is required. The boiler’s operating mode is adjusted via the regulator. The manufacturer sets the traction regulator’s price, material by execution. Because the combustion chamber can open and close, the device lets you change the temperature in the heating system. The handle-mounted temperature indicator of the coolant that exits the boiler is kept at a steady level.
In the case of an increase in the temperature of the coolant above the set mark, the thermo element affects the lever mechanism, which causes it to lower it. As a result, the chain drive closes the chamber damper, which reduces the supply of oxygen. Thus, the intensity of combustion decreases, the fuel in the chamber begins to smolder. When the temperature in the boiler drops below the given mark, the drive opens the damper. A large amount of oxygen enters the camera, the combustion intensity increases.
To ensure the optimal operation of the regulator to control the temperature, you need to connect the chain so that it can quickly change the amount of incoming oxygen. In this case, the chain should not hang out. Excessive tension of the chain leads to extension of the links and rupture of the chain.
Whatever the manufacturer, the procedure for setting the traction regulator on a solid fuel boiler is the same. The length of the chain is adjusted and fixed on the thrust door once the device is connected to the apparatus. When the regulator handle reaches the 60-degree mark, the boiler operates with the door open. The temperature indicator on the door is set to open by approximately 1 mm when the chain is fixed in place. You cannot adjust the regulator handle to the required temperature until you have completed these adjustments.
How much does the control node cost
Air is more expensive than UU filled with water. The cost of models filled with water ranges from 30,000 rubles to 60,000 rubles, while models filled with air cost twice as much.
An inexpensive control device brand is a UU Shaltan that is filled with water.
Although Air UUs are more costly, their application is more extensive. They work best in negative temperatures and should only be used in positive water temperatures. They act quickly and don’t require long delays because they have fewer excuses for false works. An electronic timer governs the functioning of air artificial intelligence.
The performance, working conditions, required speed, and protection against false works of the fire extinguishing system are taken into consideration when selecting the control unit.
The most popular type of UU are filled with water and placed in heated rooms, which have constant temperatures above zero.
Use air nodes in rooms where the temperature can drop below zero. They are more costly, but they are distinguished by their speed and resilience to phony works.
Specifications
The following UU qualities are significant to users:
- Hydraulic loss coefficient;
- Water pressure in the system;
- Response time;
- Recovery time;
- Lifetime;
- Term between major repairs.
Which portion of the water pressure is lost during device passage is indicated by the coefficient of hydraulic losses. This number varies for control nodes between 0.0005 and 0.0076, depending on the design.
Less loss occurs the greater the structure’s mass and size as well as the signaling line’s diameter.
Normalized water pressure (0.14 MPa) is maintained for both working conditions and a calm regime. when 1.6 MPa of water is pumped to put out a fire. Prior to turning on the pumps, the sensors’ operation is adjusted for minimum pressure.
Without a pause, the operation takes two seconds. 0.6 seconds in systems where performance is necessary. 11–13 seconds if a delay chamber is present; any time can be set if there is an electronic timer. It is generally set for a duration of 2 to 11 seconds; any longer than that is not advised.
Following the completion of the fire extinguishing process, the sprinkler system can be operational again. In 0.5 hours, the control unit is operational again after a fresh thermal intake is installed in the spraying head.
Typically, a UU needs to be overhauled every three years during its 10-year service life.
