The thermostat is a device for monitoring the air or water temperature that enters the device. When a temperature setpoint is achieved in the thermostat, it turns off the heating device. Subsequent inclusion occurs after the temperature decreased. Some heating devices are equipped with temperature regulators or built-in relays, but for those whose package does not include such an addition, it is purchased separately.

What does the thermostat need
Heating systems not equipped with thermostators are not convenient for use. They must be disconnected periodically, independently focusing on the level of housing level. The temperature regulator performs this operation automatically and makes it possible to heat the dwelling or industrial premises in advance.
Thermostators reduce the level of fire happiness of the heating equipment. The heater with the thermostat operates for a long time and does not overheat, due to the temperature sensor, which adjusts the level of heating. From here it follows another plus of the use of thermostators - electricity savings. Use thermostators and the owners of the aquariums. With the help of these devices, the optimum temperature in the abdication of fish is maintained.
The thermostat functions simply simply - the optimum temperature is set for an air or aqueous medium, the relay in the thermostat is triggered when the specified value is reached and turns off the heating device. It is very convenient for any types of premises - warehouses, residential buildings, administrative buildings, etc.
Thermostators work not only on heat, but also on the cold. An example of this is the equipment of refrigerators, which turns off the engine when the desired temperature is reached in the chamber. All heat regulators are divided into three main groups:
- electronic;
- electromechanical;
- mechanical.
Electronic thermostators
Electrical thermostators have one main advantage - a high indicator of the definition and adjustment of the heating of housing. They are easily configured and managed by heaters connected to them. The thermostat of this type of:
- determining the heating of the air of the sensor;
- microprocessor processing and transmitting signal;
- details of control switching, which in this case serves as a thermorel.
Use electronic thermostators to configure the total heating system of industrial building and private housing, adjusting the functioning of air conditioners and climate control. The thermostators of such a design are often included in the configuration of the "Smart House" system, they are monitored not only for heating the air in the house, but also by the number of degrees in the instruments included in the system. This is necessary to reduce the likelihood of fire.
Electromechanical thermostators
Electromechanical thermostators in design are the simplest. The heart of this device is a relay, it makes it off and connecting devices. Devices of this type are installed in iron, electric stoves, puffers and other devices for life, which change the temperature of their surface or internal elements.
The design of the relay in these devices is a group of contacts and a double metal plate. When the plate is heated, changes its position and dispels the contacts, it stops the course of the current to the plate and spiral. When cooled, the plate comes to its original position and the contacts closes. This cycle keeps the temperature at the required level.
There is another popular variety of mechanical thermostators, they have a slightly different design and principle of operation. The relay in these devices is expanding when exposed to high temperatures. This thermostat is installed in heating tanks, oil heaters. The relay in such a type of construction has the form of a cylinder filled with a sensitive to the increase and decrease in temperature by the substance. With increasing temperature, this substance expands and opens contacts. There is a special and complex chain drive. When cooled, the substance returns to the initial volume and contacts are closed.
Thermostats
The thermostat regulator is another wide-used group of thermostators in devices. One of the popular applications of the regulators of this type - heating systems. Externally, the thermostat is similar to a locking crane. Such a device helps to hold the necessary temperature level in residential, administrative and office space. Also equip automotive engines with these devices. For flexible temperature mode, the thermostat is not recommended to use the thermostat, as they have the main functioning modes, leaving the scope of which the system loses hermeticity and fails.
The thermostat design is a thermal cylinder with a rod, which is filled with a substance sensitive to temperature increase. When the substance is heated to a certain mark, it increases in volume, the rod extends out and overlaps the movement of water in the pipes.
Mechanical thermostators for infrared heaters
Infrared heaters are very popular in domestic and industrial use. The principle of their work lies in the heating of objects in the zone of radiation. These instruments, as well as other heaters, are equipped with thermostators, but somewhat different designs. The first major category of thermostators for infrared heaters - mechanical.
Mechanical thermostators for infrared heaters are presented on the market by most trademarks producing this type of product. Each brand has some structural features and differences, but in general, on the principle of operation, all mechanical thermostators are similar to each other. In most cases, the installation of such regulators is made on the wall - superimposed or crashed into it. Due to this, there is a compound of the thermostat with wiring of any type.
The range supported by the temperature thermostat - from +5 to +30 C. Dimensions of the device are small - size with an ordinary standard household outlet. This allows harmoniously to enter the equipment in the interior. The regulator has a handle to determine the temperature level, to which the heater heats up the system. There is also a button to turn off or turn on the thermostat itself.
Programmable thermostators for infrared heaters
A programmable or digital thermostat for infrared heaters makes it possible to achieve maximum comfort in the house. This is the most perfect type of equipment, easy to use and practical. The range of the set temperature is wider than that of mechanical devices and is 5-45 C. This allows you to significantly increase the scope of the equipment and the level of comfort created by them.
The main difference of programmable equipment is the ability to set a complex heating program that will function for several days or weeks. At the same time, the program makes it possible to specify a different sequence of change of temperature and control over it every day. It is equipped with such a thermostat with two sensors, the purpose of the first is to monitor the heating of the room as a whole, the second is for heating the heater itself. Programmable devices are used for smart home systems.
Choosing, what a thermostat to buy, you need to consider such factors:
- conditions of the external climate;
- the quality of thermal insulation of the heated structure;
- the number of heaters in the system;
- type of used appliances for heating.
Regulators intended for infrared heaters are able to maintain the operation of several heaters, but their total capacity should not exceed the mark of 3-3.5 kW. For circuits exceeding this value, an embedded magnetic starter is used, which redistributes the load on different network devices.
Overview of manufacturers of thermostators
1. Devi thermostators, Poland. The main part of the products of this manufacturer is intended for installation in separate buildings. Devireg TM540 and 550 models help to create optimally comfortable conditions and energy consumed.

-
- the RT500 model and its wireless version of RT500RF have 5 programs for daily work that the user specifies. The RT300 and RT300RF models support one user specified temperature level. All models are equipped with a LCD display and illumination.
Choosing a thermostat for private purposes, two main rules should be followed:
- select products that meet requests;
- pay attention to the price.
A good temperature controller will not cost less than 15-20 EUR. Cheaper products increase the risk of acquiring a fake made of low-quality materials. As a result, the losses will be calculated not only by the price of the thermostat itself, but also the equipment connected to it, if it breaks down as a result of overheating.
